Recipient cell nuclear factors are required for reprogramming by nuclear transfer.

Nuclear transfer allows the reprogramming of somatic cells to totipotency. The cell cycle state of the donor and recipient cells, as well as their extent of differentiation, have each been cited as important determinants of reprogramming success. Here, we have used donor and recipient cells at various cell cycle and developmental stages to investigate the importance of these parameters. We foun...

I-12: Nuclear Reprogramming in Bovin Somatic Cell Nuclear Transfer

Somatic cell nuclear transfer (SCNT or cloning) returns a differentiated cell to a totipotent status; a process termed nuclear reprogramming. Reproductive cloning has potential applications in both agriculture and biomedicine, but is limited by low efficiency. To understand the deficiencies of nuclear reprogramming, our research has focused on both candidate genes and global gene expression pat...

Epigenetic reprogramming by somatic cell nuclear transfer in primates.

We recently demonstrated that somatic cells from adult primates could be reprogrammed into a pluripotent state by somatic cell nuclear transfer. However, the low efficiency with donor cells from one monkey necessitated the need for large oocyte numbers. Here, we demonstrate nearly threefold higher blastocyst development and embryonic stem (ES) cell derivation rates with different nuclear donor ...

Epigenetic reprogramming and nuclear transfer

Nuclear transfer, also referred to as cloning, attracted public attention when the first mammal, the sheep Dolly, was cloned from an adult cell. In this review, we highlight some of the milestones reached in the 50 years following the first nuclear transplantations in frogs. We also address the problems associated with nuclear transfer and provide an survey on current stem-cell technology. In t...

network analysis of transcription factors for nuclear reprogramming into induced pluripotent stem cell using bioinformatics

objective: research related to induce pluripotent stem (ips) cell generation has increased rapidly in recent years. six transcription factors, namely oct4, sox2, c-myc, klf4, nanog, and lin28 have been widely used for ips cell generation. as there is a lack of data on intra- and inter-networking among these six different transcription factors, the objective of this study is to analyze the intra...
