WebThis cell is in interphase (late G _2 2 phase) and has already copied its DNA, so the chromosomes in the nucleus each consist of two connected copies, called sister chromatids. You can’t see the chromosomes very clearly at this point, because they are still in their long, stringy, decondensed form. WebAug 10, 2016 · Erasure of epigenetic memory is required to convert somatic cells towards pluripotency. Reactivation of the inactive X chromosome (Xi) has been used to model epigenetic reprogramming in mouse, but human studies are hampered by Xi epigenetic instability and difficulties in tracking partially reprogrammed iPSCs.

Highly purified SSCs and testicular somatic cells were isolated by fluorescence-activated cell sorting using SSEA-4 and THY1 as markers of SSCs and somatic cells.
WebCultured human thyroid cells were X-irradiated in vitro and assayed for resistance to 6-thioguanine. The average mutant frequency was 1.69 +/- 1.34 X 10(-5) (mean +/- SD) in controls, 3.74 +/- 2.21 X 10(-5) in cells exposed to 1 Gy, and 7.19 +/- 5.37 X 10(-5) in cells exposed to 2 Gy.
