Plasticity of photoreceptor-generating retinal progenitors revealed by prolonged retinoic acid exposure.
Retinoic acid (RA) is important for vertebrate eye morphogenesis and is a regulator of photoreceptor development in the retina. The vertebrate retina forms from a neuroepithelium that develops into a complex, layered structure of neurons consisting of
Analysis of the dynamics of limb transcriptomes during mouse development.
The development of vertebrate limbs has been a traditional system to study fundamental processes at work during ontogenesis, such as the establishment of spatial cellular coordinates, the effect of diffusible morphogenetic molecules or the translation between gene activity and morphogenesis. In addition,
Growing Without Cell Division: Mechanism Responsible for Cell Polyploidy Pinpointed?
Do Bacteria Age? Biologists Discover the Answer Follows Simple Economics
When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria.
