This interview, the 55th in our series, was published in Development last year Sperm development and differentiation are regulated by somatic cells and the extracellular signals they produce – often regulators of proteolysis. Premature or delayed differentiation can compromise fertility, and thus tight spatiotemporal control of the process is crucial. A paper in Development addresses how two secreted proteins[…]

A day in the life of a sponge lab (yes, there are labs devoted to these animals!)

Forget about those large amounts of bottles containing thousands of flies, those huge piles of boxes containing different lineages of mice or large tanks filled with happy-hopping frogs. Also, forget about transgenic, mutant, knockout litters… what I am going to tell you is the routine of an emergent lab working (or, better, trying to) with[…]

Here are the highlights from the current issue of Development: How transcriptional silencing goes into reverse The Polycomb group (PcG) machinery silences terminal differentiation genes in stem cell lineages. Reversal of this epigenetic transcriptional silencing is implicated in the selective activation of these genes during differentiation, but little is known about the mechanism of this[…]
