Galpha(s) uncouples hematopoietic stem cell homing and mobilization.
Defects of hematopoietic stem cell adhesion or migration generally lead to reduced homing to, and enhanced mobilization from, the bone marrow. In a recent publication in Nature, Adams et al. (2009) demonstrate that the guanine-nucleotide-binding stimulatory alpha subunit (Galpha(s)) can, unexpectedly, promote both phenomena.
