Lapho ezwa lokhu, ososayensi baye basebenzisa ukudala pluripotent eyenga lwama-stem cell umbhalo isici 2 - LIN28 futhi NANOG.

ucwaningo

Kufanele kuqashelwe ukuthi rejuvenation nge-stem cell, abantu 74-101 bangase bathi ngalezi ucwaningo. Amaseli zobhejane nakomaka eziningana ezibalulekile zokuguga, kuhlanganise usayizi telomere - "ofeleba" ezincane zokuzivikela, okuyinto zitholakala imikhawulo chromosome.

Telomere futhi telomerase (ukulawula enzyme yabo) kuthiwa eziyinhloko okwandisa ubude besikhathi sokuphila rejuvenation.

Amaseli telomere ngemva division kancane ngamunye bafake. Kulokhu, umsebenzi telomerase Iwukubuyisela kancane kubo, kodwa kuza isikhathi lapho ama-telomere uzokhathala, bese leli ngqamuzana liyafa.

reprogramming amaseli

Rejuvenation lwama-stem cell umzimba indlela zokuthumela reprogramming, okungase kube esikhathini esizayo esiseduze esetshenziswa ukuqeda rejuvenation. Kodwa ososayensi bathi okwamanje ekuseni kakhulu ukugubha bese uqale uhlela ukuphila kwakho phambili iminyaka engu-150.

Ukuhlolwa ku amagundane luye lwabonisa ukuthi ukusungulwa omdala stem cells usengakwazi kusho ukubhekana nobunzima obuthile.
