Improved Development of Somatic Cell Cloned Mouse Embryos by Vitamin C and Latrunculin A
Impaired development of embryos produced by somatic cell nuclear transfer (SCNT) is mostly associated with faulty reprogramming of the somatic nucleus to a totipotent state and can be improved by treatment with epigenetic modifiers. Here we report that addition of 100 μM vitamin C (VitC) to embryo culture medium for at least 16 h post-activation significantly increases mouse blastocyst formatio...
متن کاملDefective chromatin structure in somatic cell cloned mouse embryos.
Epigenetic reprogramming plays a central role in the development of cloned embryos generated by somatic cell nuclear transfer, and it is believed that aberrant reprogramming leads to the abnormal development of most cloned embryos. Recent studies show that trimethylation of H3K27 (H3K27me3) contributes to the maintenance of embryonic stem cell pluripotency because the differentiation genes are ...
متن کاملImproved development of somatic cell cloned bovine embryos by a mammary gland epithelia cells in vitro model
Previous studies have established a bovine mammary gland epithelia cells in vitro model by the adenovirus-mediated telomerase (hTERT-bMGEs). The present study was conducted to confirm whether hTERT-bMGEs were effective target cells to improve the efficiency of transgenic expression and somatic cell nuclear transfer (SCNT). To accomplish this, a mammary-specific vector encoding human lysozyme an...
متن کاملLatrunculin A Treatment Prevents Abnormal Chromosome Segregation for Successful Development of Cloned Embryos
Somatic cell nuclear transfer to an enucleated oocyte is used for reprogramming somatic cells with the aim of achieving totipotency, but most cloned embryos die in the uterus after transfer. While modifying epigenetic states of cloned embryos can improve their development, the production rate of cloned embryos can also be enhanced by changing other factors. It has already been shown that abnorm...
