blastulation การใช้
- This allows the developing TE to protrude after blastulation, facilitating the biopsy.
- During early embryonic development, paracrine / juxtacrine signaling of hCG induces blastulation and neurulation.
- Also, morphological features of the oocyte that can be obtained by standard compaction, blastulation and pregnancy.
- Gardner, R . L . ( 2007 ) The axis of polarity of the mouse blastocyst is specified before blastulation and independently of the zona pellucida . " Hum.
- Through the processes of compaction, cell division, and blastulation, the conceptus takes the form of the blastocyst by the fifth day of development, just as it approaches the site of implantation.
- Suppression of P4 signaling following withdrawal of progesterone, or treatment with the progesterone receptor antagonist RU-486 ( mifepristone ), inhibits the differentiation of hESC colonies into embryoid bodies ( blastulation ) or rosettes ( neurulation ).
- Studies using the EmbryoScope ( tm ) time-lapse incubator have used several indicators for embryo quality, such as direct cleavage from 1 to 3 cells, as well as the initiation of compaction and start of blastulation.
- An in vitro model of early human embryogenesis ( human embryonic stem cells ( hESCs ) ) has demonstrated that hCG promotes cell proliferation via the LH / hCG receptor ( LHCGR ) . hCG signaling upregulates the expression of steroidogenic acute regulatory protein ( StAR )-mediated cholesterol transport and the synthesis of progesterone in hESC . The production of progesterone at this time induces embryroid body ( akin to blastulation ) and rosette ( akin to neurulation ) formation in vitro.
