WebACTIVIN and BMP-induced mesoderm patterned into cardiac but not somitic subtypes. Conversely, PS precursors induced by GSK3-β inhibition did not generate lateral plate and cardiac mesoderm and favored instead somitic differentiation. The mechanism of these cell fate decisions involved mutual repression of NANOG and CDX2. Websomitic mesoderm (PSM) cells that give rise to bones and muscles and motor neurons in mouse and human provide insight on the mechanisms behind allochrony. They both are based on the premises that (i) in vitro models recapitulate intrinsic in vivo timing, (ii) differences exist in the tempo chivalric education
