Waxay ka soo saareen nuucyada fibroblasts ee jiirka uurjiifka ah (macaca crab-eating macaque ama Macaca fascicularis) waxayna ku dhex rogeen unugyada ukunta (ova) oo laga saaray nuucyada ay leeyihiin. Kooxdu waxay isticmaaleen laba enzymes si ay u tirtiraan xusuusta epigenetic ee nuucles loo wareejiyay inay yihiin unugyo somatic ah. Tallaabadan dib-u-habaynta muhiimka ah waxay u oggolaatay cilmi-baarayaashu inay ka gudbaan caqabadda ugu weyn ee hor istaagtay guusha nuqulinta primates ilaa hadda. Kadibna 21 ka mid ah ukuntaas ayaa la geliyey hooyo hooyo macaques, taasoo keentay lix uur, laba ka mid ah kuwa nool.
