... and Mesp2 has been prevented by the early developmental arrest of Mesp1/Mesp2 double–null embryos. Here we performed chimera analysis, using either Mesp2-null cells or Mesp1/Mesp2 double–null cells, to clarify (1)possible functional redundancy and the relative contributions of both Mesp1 and Mesp2...

... endoderm might be responsible for the maintenance of anterior neural marker expression. We also performed a chimera analysis to further study the functions of MesP1 and MesP2 in the development of mesodermal derivatives. In the chimeric embryos, dKO cells were scarcely observed in the anterior-cephalic...
