From: Sox7 is dispensable for primitive endoderm differentiation from mouse ES cells
Differentiation of Sox7-null ES cells by Gata6GR. (a, b) The morphology of XEN-like cells induced by the activation of Gata6GR with Dex treatment for 4 days in Sox7 (+/−) (a) and Sox7 (−/−) (b) ES cells. Scale bars are 200 μm. (c) Western blot analysis of the expressions of the extraembryonic endoderm-associated transcription factors in XEN-like cells with or without Sox7
