Tīmeklis2006. gada 13. jūn. · The long-term label-retaining assay indicated that ≈10% of Lin − CSCs are slow-cycling and conform to the paradigm of SCs. The BrdU pulse/chase protocol, however, did not provide information regarding the pattern of growth at the single SC level. Two main assays are used to detect immortal DNA strand segregation: label-retention and label-release pulse/chase assays. In the label-retention assay, the goal is to mark 'immortal' or parental DNA strands with a DNA label such as tritiated thymidine or bromodeoxyuridine (BrdU). These types of DNA … Skatīt vairāk The immortal DNA strand hypothesis was proposed in 1975 by John Cairns as a mechanism for adult stem cells to minimize mutations in their genomes. This hypothesis proposes that instead of segregating their Skatīt vairāk The complete proof of a concept generally requires a plausible mechanism that could mediate the effect. Although controversial, there is a … Skatīt vairāk Evidence for the immortal DNA strand hypothesis has been found in various systems.
