Study from @salkinstitute found that partial reprogramming using the #Yamanaka transcription factors (#Oct4, #Sox2, #Klf4 & #cMyc) for short periods of time:

-restored a youthful #epigenetic signature to #aging cells & extends the life span of a #premature #aging mouse model. -long-term partial reprogramming led to rejuvenating effects in different tissues, such as the #kidney & #skin, and at the #organismal level; duration of the treatment determined the extent of the beneficial effects.
