Theiler Stage 9 (E6.5) Stage Definition

The ectoplacental cone is further invaded by maternal blood and the original lumen of the uterine crypt has disappeared.  ES: Late in this stage gastrulation begins, producing the first mesodermal cells.  6.5 dpc (range 6.25-7.25)  Downs & Davies  PS - ES:  prestreak to early streak  Witschi Stage 11 (rat)  Carnegie Stage 6-7 (human)    Scale bar in microns.
