Fig. 7From: Notch signaling in mouse blastocyst development and hatchingRepresentative photographs illustrating the morphological staging of embryonic development. Mouse embryos were in vivo collected at 2.5 dpc (a), in vitro cultured, and morphologically evaluated according to Nagy et al. 2003 [44] at 3.5 dpc (cultured for 24 h; b), 4.0 dpc (cultured for 36 h; c) and 4.5 dpc (cultured for 48 h; d). CM = compact morula, BL = blastocyst, EBL = expanded blastocysts, eHBL = early hatching blastocyst, HBL = hatched blastocystBack to article page
