In Advanced Science, a team of researchers has explained how partial cellular reprogramming through the OSKM factors restores nerve repair ability to older animals. Stress as a signal This paper focuses on Schwann cells, glial cells that are often responsible for maintaining the protective sheaths of myelin around neuronal axons and help peripheral nerves to...

In a recent study, researchers investigated aging- and disease-associated changes in gene expression related to epithelial-mesenchymal transition. Inducing the Yamanaka factors in mice allowed them to rejuvenate cells and tissues and reverse some of these aging-associated changes [1]. Rejuvenating cellular identity Aging-related epigenetic changes result in decreased capacity to maintain cellular identity [2], and some...

The authors of a recent study reported that OSKM/Yamanaka factor gene therapy in rats results in higher fertility at an older age compared to controls and allows older rats to have regular cycles [1]. Rejuvenating Yamanaka factors Yamanaka Factors - Opportunities for RejuvenationDrs. Takahashi and Yamanaka showed that they could use Oct4, Sox2, Klf4, and c-Myc...

Scientists have shown that long-term intermittent reprogramming limited to hippocampal neurons increases their fitness and improves cognitive function in a mouse model of Alzheimer’s disease [1]. Targeted in time and space Partial cellular reprogramming is one of the hottest directions in longevity research for a reason: it allows to rejuvenate cells without driving them all...

Scientists have shown that prolonged, continuous expression of reprogramming factors counters cognitive decline in old rats and probably decreases their epigenetic age [1]. Reprogramming and cognitive function Cellular reprogramming, the act of bringing differentiated cells back to a stem-like pluripotent state by expressing certain genes, has been one of the hottest subfields in longevity in...

Scientists have found that partial cellular reprogramming, both full-body and restricted to specific brain regions, rescues neurogenesis in the brains of old mice [1]. Cells going back in time Yamanaka Factors - Opportunities for RejuvenationDrs. Takahashi and Yamanaka showed that they could use Oct4, Sox2, Klf4, and c-Myc (OSKM) to reprogram cells back to pluripotent, embryonic...
