Regulation of stem cell pluripotency and neural differentiation by lysophospholipids.

Lysophospholipids are bioactive signalling molecules able to act through the binding of their specific G-protein-coupled receptors to exert pleiotropic effects on a wide range of cells. The most widely studied signalling lysophospholipids are lysophosphatidic acid (LPA) and sphingosine-1-phosphate (S1P). LPA and S1P have been identified to have widespread developmental, physiological and pathological actions in the central nervous system and more recently have been shown to induce biological effects on various stem cell types. This review aims to summarise the current knowledge on LPA and S1P regulation of embryonic and neural stem cell biology. Copyright (c) 2009 S. Karger AG, Basel.
