[Morphologic characteristics of successive transformations of mouse blastocysts into teratoids during development under the testicular capsule].
Blastocysts of the CBAXC57Bl mouse strain transplanted under the testicular albuminous membrane normally develop (but delay in time) during 7-9 days forming embryos at the stage of the deep neural groove. The data obtained demonstrate that there is a definite autonomy in the development of early embryos not depending on any influence from the uterus at this stage. Desorganization of the embryo occurs 9-11 days after transplantation of the blastocyst. Further (14-20 days after transplantation) as a result of active histogenesis and atypical organogenesis, immature teratoid is forming. Secondary giant cells of the trophoblast develop in the presence of the internal cellular mass derivatives.
