BSDB/GenSoc 2020 had a fantastic planned line up of plenary speakers. Over the past three days we managed to sit down for a virtual chat with five of them – in these short videos, you’ll hear about their science, their connection to the BSDB, how the coronavirus has been affecting their labs, and more. […]

This interview, the 75th in our series, was recently published in Development. Our understanding of lineage decisions in early human development has been greatly aided by embryonic stem cell lines, which avoid many of the practical and ethical difficulties of in vivo material. A new paper in Development exploits naïve human embryonic stem cells to generate in vitro models for the extra-embryonic[…]

This interview, the 74th in our series, was recently published in Development. Dysregulated activity of cell surface proteolytic enzymes has a wide range of developmental and pathological consequences, but the underlying mechanisms are often poorly understood. A new Development paper uses mice to model a severe inherited form of enteropathy and the role of the serine protease matriptase[…]

This interview, the 73rd in our series, was recently published in Development. Animal cytokinesis is driven by an actomyosin ring that assembles at the cell equator and constricts to physically separate the two daughters. Although myosin is known to be essential for cytokinesis in multiple systems, whether this requirement reflects its motor or actin crosslinking activities has[…]

This interview, the 72nd in our series, was recently published in Development. Heart development in mammals is a beautifully complex process. Patterning, proliferation and differentiation are all coordinated with cell movements and tissue morphogenesis (for instance elongation, fusion, folding, looping). However, our knowledge of the molecular regulators of heart development currently outstrips what we know about the[…]

This interview, the 71st in our series, was recently published in Development. Our understanding of many fundamental aspects of early human development is still in its infancy, but a promising avenue for research uses advanced in vitro culturing techniques. For instance, confining human embryonic stem cells to micropatterned substrates and directing differentiation with signalling molecules has proved a powerful[…]

This interview, the 70th in our series, was recently published in Development. Drosophila wing discs are epithelial sac-like organs and a powerful model for investigating the link between proliferation and patterning. Of particular interest is the question of how single cells in the disc integrate information regarding position and growth control, as morphogens that pattern an axis can[…]

This interview, the 69th in our series, was recently published in Development. The apical hook is a transient structure that functions to protect the vulnerable apical meristem from damage when the seedling penetrates the soil. Although some of the molecular players regulating its development have been identified, many aspects have remained opaque, including how an early auxin[…]

This interview, the 68th in our series, was recently published in Development. See also the Press Release associated with the paper and also Brazilian newspaper Folha’s piece on the work Retinal ganglion cells connect the retina to the brain, and their degeneration underlies glaucoma, which is the leading cause of irreversible blindness in humans and currently untreatable.[…]

This interview, the 67th in our series, was recently published in Development Most bones in the vertebrate skeleton are made in the same way – endochondrial ossification – yet they display a variety of shapes and sizes. The question of how these unique bone morphologies, including the superstructures that protrude from their surfaces, arise during development is[…]
