STAT3 has been studied extensively in the context of self-renewal of naïve pluripotent mouse embryonic stem cells. We uncovered acute roles for STAT3 and its target, TFCP2L1, in maintenance of epiblast and primitive endoderm duringin vivodiapause. On an outbred genetic background, we observed consistent developmental retardation from implantation until embryonic day 11.5, beginning with significant reduction of epiblast cells at implantation inStat3null embryos. Remarkably, mutants closely resemble non-affected embryos from the previous day at all postimplantation stages examined. We attribute this phenotype to loss of the active serine phosphorylated form of STAT3 required for neural differentiation and implicated in growth defects in mice and humans. Bulk RNA-sequencing analysis of isolated epiblasts revealed compromised lipid metabolism inStat3null embryos by embryonic day 6.5. Furthermore, we demonstrate that gastruloids generated fromStat3null ESCs failed to extend the posterior axis or maintain BRACHYURY expression and were underrepresented in this region when mixed with wild type cells in chimaeric gastruloids. Our study implicates a role for STAT3 in temporal control of embryonic progression and metabolic mechanisms.
