Wnt to notch relay signaling induces definitive hematopoiesis

Cell Stem Cell. 2011 Jul 8;9(1):2-4. doi: 10.1016/j.stem.2011.06.011.

Abstract

The molecular mechanisms specifying hematopoietic stem cells (HSCs) in the vertebrate embryo remain poorly understood. Recently in Nature, Traver and colleagues demonstrate that timed wnt to Notch relay signaling across multiple cell types serves as an early upstream mechanism of HSC induction in zebrafish (Clements et al., 2011).
