... and from changes in the expression of genes marking the excretory system. Finally, we show that HrT, a T-box transcription factor, is a Bmp-regulated gene that has an essential function in cloacal development. We conclude that sustained Bmp signaling plays an important role in specification...

... in a number of cell lineages in the developing peripheral and central nervous systems, as well as in the excretory system. In the cranial region at day 8.5-9.5, c-ret mRNA was restricted to a population of neural crest cells migrating from rhombomere 4 and forming the anlage of the facioacoustic ganglion...
