Abstract:
:Specialized areas in the vertebrate retina are critical for high-acuity vision, yet the molecular mechanisms driving the development of high-acuity areas (HAAs) remain largely unknown. In Developmental Cell, da Silva and Cepko (2017) show that restricted degradation of retinoic acid and elevated FGF8 signaling give rise to the chick HAA.

评论,杂志文章abstract::The gastrulating vertebrate embryo develops three germlayers: ectoderm, mesoderm, and endoderm. Zebrafish endoderm differentiation starts with the activation of sox17 by casanova (cas). We report that spg (pou2/Oct4) is essential for endoderm formation. Embryos devoid of maternal and zygotic spg function (MZspg) lack ...
