Cortical bone maturation in mice requires SOCS3 suppression of gp130/STAT3 signalling in osteocytes.

abstract：:Forebrain precursor cells are dynamic during early brain development, yet the underlying molecular changes remain elusive. We observed major differences in transcriptional signatures of precursor cells from mouse forebrain at embryonic days E8.5 vs. E10.5 (before vs. after neural tube closure). Genes encoding protein ...
