Abstract

WNT and PGE2 signaling pathways are each associated with stem cell activity in the hematopoietic system. In a recent issue of Cell, Goessling et al. (2009) use the zebrafish model to reveal a conserved PKA-dependent mechanism that connects the two pathways via beta-catenin, enhancing stem cell proliferation and tissue regeneration.
