Freeze-Dried Somatic Cells Direct Embryonic Development after Nuclear Transfer
The natural capacity of simple organisms to survive in a dehydrated state has long been exploited by man, with lyophylization the method of choice for the long term storage of bacterial and yeast cells. More recently, attempts have been made to apply this procedure to the long term storage of blood cells. However, despite significant progress, practical application in a clinical setting is stil...
متن کاملUncoupled Embryonic and Extra-Embryonic Tissues Compromise Blastocyst Development after Somatic Cell Nuclear Transfer
Somatic cell nuclear transfer (SCNT) is the most efficient cell reprogramming technique available, especially when working with bovine species. Although SCNT blastocysts performed equally well or better than controls in the weeks following embryo transfer at Day 7, elongation and gastrulation defects were observed prior to implantation. To understand the developmental implications of embryonic/...
متن کاملEffects of Various Activators on Bovine Embryonic Development Following Intracytoplasmic Sperm Injection
The objective of this study was to compare the effectiveness of various combination activators of bovine oocyte following intracytoplasmic sperm injection (ICSI) in terms of cleavage and embryo development. Bovine ICSI oocytes were treated with a variation of treatments of combined or single activators as follows; 30 V for 15 x 2 μsec of electrical pulse +10 μg/mL cycloheximide (CHX),7% ethanol...
متن کاملEmbryonic Development following Somatic Cell Nuclear Transfer Impeded by Persisting Histone Methylation
Mammalian oocytes can reprogram somatic cells into a totipotent state enabling animal cloning through somatic cell nuclear transfer (SCNT). However, the majority of SCNT embryos fail to develop to term due to undefined reprogramming defects. Here, we identify histone H3 lysine 9 trimethylation (H3K9me3) of donor cell genome as a major barrier for efficient reprogramming by SCNT. Comparative tra...
متن کاملHuman Embryonic Stem Cells Derived by Somatic Cell Nuclear Transfer
Reprogramming somatic cells into pluripotent embryonic stem cells (ESCs) by somatic cell nuclear transfer (SCNT) has been envisioned as an approach for generating patient-matched nuclear transfer (NT)-ESCs for studies of disease mechanisms and for developing specific therapies. Past attempts to produce human NT-ESCs have failed secondary to early embryonic arrest of SCNT embryos. Here, we ident...
