Neural crest stem cell maintenance by combinatorial Wnt and BMP signaling

Abstract: Canonical Wnt signaling instructively promotes sensory neurogenesis in early neural crest stem cells (eNCSCs) (Lee, H.Y., M. Kléber, L. Hari, V. Brault, U. Suter, M.M. Taketo, R. Kemler, and L. Sommer. 2004. Science. 303:1020–1023). However, during normal development Wnt signaling induces a sensory fate only in a subpopulation of eNCSCs while other cells maintain their stem cell features, despite the presence of Wnt activity. Hence, factors counteracting Wnt signaling must exist. Here, we show that bone morpho… Show more

“…Complementary to this, embryos expressing a constitutively active form of b-catenin specifically in NCSCs develop sensory neurons at the expense of virtually all other neural crest derivatives . Recently, BMPs have been shown to antagonize this Wnt response, but when added simultaneously with Wnt1 suppress all neural differentiation and maintain NCSC multipotency (Kleber et al, 2005). These data indicate that in NCSCs combined BMP and Wnt signals regulate self-renewal, whereas the individual factors alone promote specific lineage differentiation.…”

“…Wnts on the other hand direct NCSCs towards sensory neuronal fate . Surprisingly, unlike their individual activities, treating NCSCs with Wnt and BMP together maintains the cells in a pluripotent state (Kleber et al, 2005). Since Wnt pathway components interact physically with Smads (Labbe et al, 2000), this distinct response to concomitant activation may reflect unique cellular activities of this crosstalk.…”

“…During neural crest development, Wnt and BMP act synergistically on early, emigrating neural crest stem cells (eNCSC) to suppress differentiation and keep the cells in a multipotent stem cell state [18]. Wnt signaling on its own instructively promotes sensory neurogenesis in eNCSCs [19,20].…”
