Changing of the cell division axes drives vulva evolution in nematodes.

abstract：:Induction and branching morphogenesis of the prostate are dependent on androgens, which act via the mesenchyme to induce prostatic epithelial development. One mechanism by which the mesenchyme may regulate the epithelium is through secreted growth factors such as FGF-10. We have examined the male reproductive tract of...
