The last day of the ISDB saw also the last plenary session. One of the highlights of this session was also a talk by Patricia Delgado. Patricia works on the molecular and evolutionary basis of butterfly wing patterning. Her talk included beautiful pictures of butterflies, including an image (not from her lab) of the alphabet written on naturally occurring butterfly wing patterns.

There were two more concurrent sessions, before a few free hours in the afternoon. This being the last day in Cancun, and such a sunny day as well, conference attendees could probably be spotted in every pool/beach in Cancun! Everyone was then back to the conference center for the conference dinner. But a surprise expected us: by the entrance were three actors dressed in quite impressive mayan-inspired outfits! It became the thing to do, to take photos with them. Not even Nobel prize winners were immune, as Martin Chalfie was spotted posing!

The conference dinner then took place, and included the poster prize award ceremony. With three different organisations giving prizes, a lot of the students and postdocs saw their work recognized at this meeting. As is the tradition here on the Node, the winner of the poster prize at the BSDB, Aditya Saxena (who we interviewed a few weeks ago) interviewed the winner of the SDB poster prize, Kara Nordin- so look out for this interview here on the Node soon! The band then took over, and the combination of alcohol and music had the effect that it always has- a lot of scientists on the dance floor!

Although it is sad to see the end of this meeting, and leave the sunny Cancun, there is definitely something to look forward to: it was announced today that the next ISDB meeting in four years time will take place in Singapore, where the new ISDB president, Phil Ingham, is based. It seems that developmental biologists know how to choose good locations to hold their meetings!

Today was the day when the excellent work of many developmental biologists was recognized by the community. The first prize to be awarded was the brand new Latin American Society of Developmental Biology prize. The winner, Roberto Mayor, was awarded this prize not only for his excellent body of work on neural crest cells, but also his efforts in promoting developmental biology in Latin America- he was the founder and first president of the LASDB, and is still very much involved, running for example, an embryology course in Chile every year. The actual prize was a beautiful and unique art piece by a Brazilian artist- a very special prize indeed. On a lighter note, Roberto Mayor also received an additional prize. Marianne Bronner awarded him a more comical gift, from all the neural crest scientists who are not fortunate enough to work, like him, in the more tractable Xenopus. Roberto then delighted the audience with a great talk on the mechanisms at work in neural crest migration.

The two prizes received by Roberto Mayor. Any guesses on which one was the official prize?

Marianne Bronner was herself the receiver of an award today- the Conklin Medal awarded by the SDB to recognize her work. She very sweetly thanked her current and previous lab members (her ‘progeny’ as she calls them) for their hard work that made it all possible, and for having contributed for her nomination to the award. We interviewed Marianne today, so look out for the interview on the Node soon. Other awardees included Bill Wood, who was awarded the Victor Hamburger Outsanding Educator Prize, for his many contributions to the way science is taught (or should be taught) in the lecture room. Another awardee was John Fallon, who received a SDB Lifetime Achievement Award for his body of work on limb development.

But the conference was not only awards. There were of course more concurrent sessions, covering a range of topics: from how environmental factors can influence development to cell shape and the cytoskeleton. At the evening poster session a rumour started going around that turtles could be spotted by the beach. And we must confess that we did go for a night walk on the beach, and that we could observe turtles laying their eggs. And even if a beach at the back of a strip of hotels cannot be really considered their natural habitat, after so many talks using turtles as subjects of study it was nice to see these beautiful animals in the ‘wild’!

Day 3 of the ISDB was really only half a day, with the only free afternoon/evening in the intense meeting program.

The first part of the morning featured two parallel sessions. One of the sessions was a roundtable discussion on how to succeed in science, and included a panel of very successful developmental biologists, sharing their advice and experience. The Node, however, attended the other session, an Education symposium sponsored by the SDB. It included a series of talks by different scientists who teach developmental biology to undergraduates, providing case studies and suggestions on how to engage students and effectively teach developmental biology concepts. One of the highlights of this session included the case study of Michael Barresi, who developed a semester-long practical class in which students learnt about embryonic development by testing the effects of crude oil in zebrafish development. Different students conducted proper scientific research on the effects on different aspects of development, and presented their results in a scientific symposium-style gathering at the end of the course. Some of the most enthusiastic students even continued the work during the summer, culminating with the publication of a paper. According with Michael Barresi, students cared about this project for two reasons: first, because they were conducting proper scientific research, and second because the project focused on a very topical issue that the students could relate to and feel engaged with (the big Gulf of Mexico oil spill had happened very recently before this course took place).

Indeed, the importance of teaching basic developmental biological concepts alongside real world, topical contextualisation of the importance of these studies, was a point stressed in this session. If the students care about it, they will be interested. Other useful suggestions included the use of texting, twitter or simple cards with A, B, C and D on them to ask questions to the whole class during lectures, making lectures dynamic and the students more engaged.

Following the education symposium there were several concurrent sessions, and the Node chose a session on emerging model organisms. One of the highlights of this session was a talk by Shigeru Kuratani, on the evolution of turtle body plans. His talk included some incredibly useful (and professional looking!) animations, which showed great 3D representations of the bones and muscles being studied, and how they are arranged in different organisms across evolution. They say a picture is worth a thousand words, and indeed it should not be underestimated how they can help understand complex scientific concepts. Another highlight from this session was Nanette Nascone-Yoder, who introduced the audience to the Budgett’s frog. The audience reacted both to the potentially useful properties of this animal for developmental biology studies (e.g. fast development rates, and big embryo size), but also to some more creepy features, such as how bigger tadpoles often eat their smaller siblings!

Not a Budgett’s frog… but this little fellow has been spotted at a poster, alongside a QR code linking to more poster images!

During the afternoon off the Node was not resting- we have been interviewing some great scientists during this ISDB meeting, and the interviews will be posted on the Node in the near future. As for tomorrow… another full day of science ahead of us!

Let’s be honest- the first talk of the morning session in a conference is always badly attended, right? Well, not at the ISDB! In a clever move by the organisers, the very first speaker of day 2 was no other than Sir John Gurdon, and consequently the room was full. The chair of that plenary session was Eddy DeRobertis, who did a postdoc with John Gurdon. When introducing him, Eddy DeRobertis mentioned not only John Gurdon’s scientific achievements, and his recent Nobel Prize, but also his contributions to the scientific community: as president of the ISDB, his work at the Company of Biologists and Development, his travels around the world to teach and lecture. At Eddy DeRobertis’s request the whole room welcomed John Gurdon to the podium with a standing ovation, a memorable moment of this ISDB.

Day 2 also saw the beginning of the concurrent sessions. Each of the three simultaneous sessions has an overall theme that runs throughout the conference: ‘Molecules to Cells’, ‘Cells to Organs’ and ‘Organs to Organisms’, reflecting in a way the scale of the research presented in each session. The themes being covered each time vary however. For example, the ‘Organs to Organisms’ session in the morning focused on models of human diseases, while the one in the afternoon featured growth control. In addition to the plenary sessions, you can imagine the wide range of amazing research that is being covered at this meeting!

Another very nice moment of day 2 was the ISDB Harrison Medal Lecture. The Harrison Medal was previously known as the Harrison Prize, and was established in 1981 to recognize ‘scientists whose contributions have significantly advanced the field of developmental biology’. It is only awarded every four years, and hence to only a very select number of scientists. At this ISDB, the Harrison Prize became the Harrison Medal, and many of the previous winners, including Sir John Gurdon, Eddy DeRobertis, Masatoshi Takeichi and Elliot Meyerowitz, were present to receive their own, brand new, Harrison Medal. The winner of this year’s Harrison Medal was Janet Rossant. She gave a very entertaining talk- a fascinating overview of her career, which started as an undergraduate being taught by John Gurdon (science is such a small world!), but which also included some of the scientific questions that interest her the most at the moment. The Node will be interviewing Janet Rossant, so look out for a post about it in the near future.

The day concluded with another poster session. And for those of you that might have been jealous of the beautiful beach photo of the previous post, you might like to know that is not always openly sunny here in Cancun, and that there was also some rain!

Final day at the ISSCR. No posters. No concurrent sessions.  Just pure plenary all day. And indeed, the eclectic mix of talks provided a fitting end to 4 days of diverse science.

Ian Chambers kicked things off with an excellent talk describing the surprising recent finding by his laboratory that reduced levels of Oct4 actually improves self-renewal of mouse ES cells and reduces heterogeneity. Elena Cattaneo presented some beautiful stainings of early neural development in human fetuses, work that will surely interest many in the field, while Oliver Brustle gave a good overview of his laboratories work in modelling neural disease using neural stem cells derived from pluripotent stem cells. Benoit Bruneau described his labs impressive efforts to characterise the epigenome of cells at various stages during in vitro cardiac differentiation while Mitinori Saitou provided fascinating insights into the transcription factor control of primoridal germ cell specification. The morning talks were noteworthy not only for their high quality but also the diversity of experimental approaches used; including an assortment of pluripotent stem cell manipulations, reprogramming strategies, in vitro differentiation, -omics, and human in vivo studies.

The afternoon session talks were equally strong. Ken Zaret introduced characteristically meticulous work looking at pioneer transcription factors and the manipulation of chromatin states during both cellular differentiation and reprogramming. Kristin Baldwin presented her recent attempts to characterise the somatic mutational spectra using the formidable combination of somatic cell nuclear transfer (using terminally differentiated neurons) followed by ES cell derivation and whole genome sequencing! The theme of nuclear transfer then continued as one of the most eagerly awaited speakers – Shoukhrat Mitalipov – took to the stage. The recent publication of his derivation of cloned human ES cells created a major stir in the build up to the conference and many were eager to hear the full story of this major feat. They weren’t disappointed and were also treated to his thoughts on the applicability of this technique in the treatment of mitochondrial diseases. Next, Shinya Yamanka returned to the platform to present Marius Wernig with the ISSCR Outstanding Young Investigator Award. Wernig was then given the opportunity to present the work that merited this accolade, namely his groundbreaking studies on trans-differentiation. As well as giving the background to these landmark findings he presented more recent data in which he has taken an –omics approach to try and better characterise the process – including slavishly mapping the binding pattern of the ‘reprogramming’ factors in different cellular contexts. His talk provided an indication that not all his chosen transcription factors function in the same way during the transdifferentiation process, and he presented evidence of pioneer factor activity – an interesting link to Ken Zaret’s talk. Next, the topic shifted to regenerative medicine and included fascinating talks from Hans Snoeck, Graziella Pellegrini and Timothy Bertram. The later two presentations featured data generated following cell transplantation into patients – a goal of many in the field and an exciting way to finish the conference. However, there was just enough time for Eric Lander to provide an intriguing insight into his adventures unlocking the secrets of the human genome – admitting in the process that everything he taught his undergraduate students about the human genome in 2001 has now been proven wrong! I wonder what he taught this year that will suffer the same fate…?!

With a goodbye from Shinya Yamanaka, in his own inimitable style, the 2013 ISSCR came to an end. Although one final surprise came in the lobby where we were met by not only a free bar, but a free bar with some decent beers behind it too! Next year rolls on to Vancouver – although this blogger may well be hanging up his keyboard well before then!

Due to lack of internet at the ISDB conference venue, it is not possible for the Node to tweet live from the conference. Instead we will try to post regular updates!

Day one of the International Society for Development Biology meeting, and boy is it hot here in Cancun! Not that anyone is complaining really- the Caribbean sea looks beautiful, and it is likely that conference attendees might be going for a morning swim before the morning sessions… not a bad way to do scientific conferencing!

The main conference started this afternoon, but many attendees arrived a few days earlier for the satellite symposium on the establishment and breaking of the left-right axis in development and disease. This will be the topic of a later post.

The conference started with a Presidential symposium packed full of interesting talks. Alejandro Sanchez Alvarado kicked off the event with a talk about his research on planaria. These little organisms have amazing regenerative properties, and this ability relies on the presence of adult stem cells called neoblasts. A lot of his talk, however, focused on the unusual embryogenesis of planarian which includes, among others, a yolk localized on the outside of the egg! He also suggested that maybe in the age of molecular biology we might need to develop a new vocabulary to describe embryological processes.

The next speaker was Celest Nelson. Cells in the developing embryo not only apply forces to their neighbors but are also exposed to a complex mechanical environment (e.g. surrounding fluids or contracting movements of nearby tissues). Her lab uses both experimental biology and computer modeling to address how some of these forces can influence processes such as the branching of the lung. The interplay between mechanical forces and known chemical and genetic pathways was also the topic of a later talk by Elliot Meyerowitz. He focused on how patterns are established in the formation of plant meristems, and his talk included beautiful images of meristems.

Elly Tanaka described the work of her lab and others on how the mechanisms of muscle regeneration following limb amputation varies between salamander species. Finally, James Sharpe talked about his work combining advanced imaging with computational modeling to understand how vertebrate limb shape is achieved.

In addition to the great talks, one of the highlights of the first day was actually in the RIKEN institute booth. Up for collection were beautiful postcards of model organisms portrayed in the style of traditional Japanese decorative arts. You might remember an older post by Eva where she first mentioned these beautiful designs, and which included a link to a page where you can download them. Following the tradition of bringing developmental biology and Japanese traditions together, members of the RIKEN institute were also distributing developmental biology-themed origami! In beautiful Japanese patterns, and including instructions on how to make your own model organism, these were definitely very popular! If you are at the meeting, this is definitely one to collect. Alongside, of course, the Node tea bags! Although the hot weather here in Mexico means that you might have to wait to drink it until you get back to the lab…

After a fun night socialising, the stem cell science kicked off again in earnest on Friday morning. The morning session turned to ‘Cell and Gene Therapy’ – the final goal of many at the meeting. David Williams and Alesandra Biffi provided fascinating insights into the past and future of the gene therapy field, with a particular focus on gene delivery using haematopoeitic stem cells (HSCs). It’s good to see that the gene therapy has had somewhat of a resurgence in recent years, in part due to its interface with stem cell biology. The ethical dilemmas that these experimental therapies undoubtedly raise were summarised and expanded upon by Nancy King, while Sarah Ferber described a different approach to regenerative medicine, detailing her work on transdifferentiation of liver to pancreas as a potential therapy for diabetes. The final talk of the morning plenary came from Charles Murry who works on cardiac regeneration. He described the challenges – financial, practical and scientific – of using the non-human primate (NHP) as a model to study cell therapy for cardiac disease. Indeed, throughout the conference there have been frequent discussions about how we can properly characterise human pluripotent cells and their derivatives, and many have expressed the opinion that validating findings in the NHP is an important step. Murry’s contribution certainly focussed the debate on both the trials and benefits of such an approach. The sight of human ES cell-derived cardiomyocytes integrating and apparently functioning in vivo in the NHP heart was certainly a very exciting end to the morning plenary– regardless of your stance on NHP research.

The concurrent sessions included epigenetics, HSCs, chemical conrol of stem cell behaviour, organ development, stem cell therapies and germ cell biology. The two main speakers in the germ cell session were presenting on haploid ES cells – an exciting new tool in stem cell biology. Jinsong Li provided a good overview of the field and his own work in the mouse system, before describing the successful derivation of NHP haploid ES cells.  Josef Penninger focussed on the application of mouse haploid cells for genetic screens and his belief that ‘yeast genetics’ is now possible in mammalian cells. He also plans to make the powerful platforms his lab has developed accessible to the whole community – a massive undertaking for which he deserves a great deal of credit. Robin Hobbs brought the focus back to germline developmental biology with his latest insights into Tsc2-mTORC1 signalling in spermatogonial stem cells and I was delighted to be able to share some of my work on the connection between pluripotency and the germline. Concurrent session 2 featured many more exciting presentations, including sessions on immunology, cancer and chromatin regulation – something for everything on another full day of science.

In the evening Shinya Yamanaka hosted the president’s reception at the lavish Harvard Club in town. In an entertaining speech he revealed that the phone call from Stockholm interrupted his attempts to fix his washing machine – ‘luckily I don’t have to do this any more’ he quipped!

Day 2 featured a full scientific program, including a morning plenary and two afternoon sessions with concurrent talks running in five different rooms. Luckily many of the talks are being videoed and will be available to attendees for a few weeks after the event – a good idea as it’s impossible not to feel like you’re missing exciting science even with the most careful scheduling.

We kicked off with a disease modelling session, certainly a popular topic which has also featured in many posters and short talks throughout the conference so far. It is clear that many labs and institutions are investing huge efforts in collecting and cataloguing induced pluripotent stem (iPS) cells from patients with a vast array of different diseases. The plenary talks from Lawrence Goldstein, Haruhisa Inoue and Joseph Wu focussed on using iPS cells to interrogate the pathogenesis of amyotrophic lateral sclerosis (ALS), Alzheimer’s disease and cardiovascular disease. The general consensus was that the standard of the presentations was very high, really raising the bar of what can be achieved even when modelling complex diseases in the dish. Ludovic Vallier also presented his lab’s efforts to understand genetic and phenotypic variability in a large cohort of iPS cell lines derived using different tissues of origin and reprogramming methods. iPS cells were also well represented in the concurrent session on pluripotency and there remains a great deal of interest in the mechanism of reprogramming. A particularly noteworthy talk by Jacob Hanna presented incredible data demonstrating that knocking out one component of a chromatin remodelling complex can lead to 100% reprogramming efficiency on expression of the Yamanaka factors. The cell fate conversion session featured talks on ‘direct reprogramming’ (or trans-differentiation) emphasising not only how malleable cell fate is, but also the challenges in manufacturing fully functional, terminally differentiated cell types in vitro. Indeed, some discussions have focussed on whether this is necessary or even desirable in all contexts – as long as cells can safely and efficiently ‘do the job’ asked of them. The idea of completely new cell types is certainly intriguing, although maybe not to the developmental biologist still struggling to understand the cells we have already! On a related note, Pentau Liu presented his lab’s work on designer transcription factors which are custom made to turn your gene of interest on or off. Certainly a neat trick which sparked debate as to how one might utilise these in the future to answer different biological questions. Other sessions included neural stem cells, tissue engineering, stem cell signalling and niches, aging and metabolism, and ‘new technologies’ to name but a few. Each concurrent session has also featured poster teasers which are an excellent recent addition to many conferences – one speaker even used their allotted time to sing/rap about their work. I’m sure this poster got plenty of foot traffic… although I’m not convinced this approach will, or should (!), necessarily catch on!

The day ended with a social event for young investigators at a local Irish bar – although even the more senior scientists who sneaked in couldn’t resist the lure of the dance floor! I won’t name any names… but the blood stem cell field was certainly well represented!

Are you attending the ISDB meeting starting this sunday in Cancun, Mexico? If not, don’t worry- the Node will be there, and we will be tweeting using the #ISDB2013 hashtag. If you are not a Twitter user, Cat will also be posting updates from the meeting here on the Node, so that is another way you can follow the conference!

If you are going, then why not say hello? Cat will be at the Company of Biologists booth (Booth 10) quite a lot of the time with some Node freebies (including our tea bags!), but feel free to chat to her if you see her around elsewhere. It would be great to meet some of you, and find out about what you think about the Node. Hopefully see you there!
