| The blastocyst forms into a hollow ball that implants itself in the uterine lining. |
| Their reproductive cycle is characterized by a period of embryonic diapause, during which the blastocyst suspends implantation and development. |
| Normally, the result of doing this is a chimera an animal that consists of a mixture of cells derived from the injected cell and the blastocyst. |
| You had mentioned that twins can develop when the inner cell mass splits in the blastocyst and forms two embryos enclosed in a common trophoblast. |
| After about five or six days in vitro human embryos will reach a stage that is called the blastocyst stage. |
| Stem cells would be harvested from the blastocyst and transformed into the desired tissues for transplant. |
