Cell ablation experiments have shown that fates of teloblasts N, P and Q in Tubifex embryos are determined rigidly as early as their birth. In contrast, the O teloblast and its progeny...

Experiments have revealed a number of cell interactions at this stage that transfer patterning information from cell...

Thus, the expression of Wnt-5a in the adult uterus occurs in developmentally plastic stromal cells involved in cell-cell interactions with epithelium. By contrast, adult vaginal stroma...
