Hatching of blastocyst
WebIronically, blastocyst hatching is tacitly linked to peri-implantation events, although it is a distinct developmental phenomenon. The exact molecular network regulating hatching is still unclear. A number of implantation-associated molecular factors are expressed in the pre-implanting blastocyst. WebThe blastocyst so formed consists of two distinctive tissues, the outer trophoblast, and the inner cell mass. Finally, the stretched zona pellucida breaks and releases the blastocyst. This is known as hatching. The blastocyst then undergoes implantation in the uterus. The blastocyst adheres to the endometrial wall of the uterus.
