Mammalian embryonic development is a complex process driven by self-organization, and understanding this process remains a fundamental challenge in biology. Stem cells have been used as in vitro models for investigating mammalian development and are promising building blocks for regenerative therapies. Recent advances in stem cell models of embryos have focused on signaling activities that underpin cell fate decisions in space and time.
Mammalian embryonic development is a complex process driven by self-organization. Understanding how a fertilized egg develops into an embryo composed of more than 200 cell types in precise spatial patterns remains one of the fundamental challenges in biology. Pluripotent stem cells have been used as in vitro models for investigating mammalian development, and represent promising building blocks for regenerative therapies. Recently, sophisticated stem cell-based models that recapitulate early embryonic fate patterning and morphogenesis have been developed. In this article, we review recent advances in stem cell models of embryos in particular focusing on signaling activities underpinning cell fate decisions in space and time.
