John Gurdon is a Distinguished Group Leader in the Wellcome Trust/Cancer Research UK Gurdon Institute and Professor Emeritus in the Department of Zoology at the University of Cambridge. In 2012, he was awarded the Nobel Prize in Physiology or Medicine jointly with Shinya Yamanaka for work on the reprogramming of mature cells to pluripotency, and his lab continues to investigate the molecular me...

The process of 'cell reprogramming' can be achieved by somatic cell nuclear transfer, cell fusion with embryonic stem cells, exposure to stem cell extracts, or by inducing pluripotentcy mediated by defined factors giving rise to what are termed induced pluripotent stem cells. More recently, the fate of a somatic cell can be directly induced to uptake other cell fates, termed lineage-specific re...

Direct reprogramming of somatic cells into a pluripotent state has been achieved with a set of just four transcription factors. Many scientists and medical doctors are trying to elucidate the causes of intractable diseases and discover new drugs using the newest types of technology. Various methods have been developed to produce clinical-grade fully reprogrammed cells for cell transplantation t...

Although somatic cell nuclear transfer (SCNT) and induction of pluripotency (to form iPSCs) are both recognized reprogramming methods, there has been relatively little comparative analysis of the resulting pluripotent cells. Here, we examine the capacity of these two reprogramming approaches to rejuvenate telomeres using late-generation telomerase-deficient (Terc(-/-)) mice that exhibit telomer...

Low development of somatic cell nuclear transfer embryos could be due to the incomplete DNA methylation reprogramming, and Dnmt1s existing in donor cells may be one cause of this disrupted DNA methylation reprogramming. However, the reprogramming pattern of Dnmt1s and its effect on DNA methylation reprogramming in cloned embryos remain poorly understood. Here, we displayed that along with the s...

A surprising link between innate immunity and nuclear reprogramming is reported by Lee et al.; this discovery may boost the efficiency of stem cell production.

Aberrant epigenetic nuclear reprogramming results in low somatic cloning efficiency. Altering epigenetic status by applying histone deacetylase inhibitors (HDACi) enhances developmental potential of somatic cell nuclear transfer (SCNT) embryos. The present study was carried out to examine the effects of Oxamflatin, a novel HDACi, on the nuclear reprogramming and development of bovine SCNT embry...

Human adipose tissue stem cells (ATSCs) can differentiate into various types of cell in response to lineage-specific induction factors. Reprogramming cells using nuclear and cytoplasmic extracts derived from another type of somatic cell is an effective method of producing specific types of differentiated cell. In the present study, the ability of reprogrammed ATSCs to acquire epidermal keratino...
