Influence of metabolic DNA on determinations of the cell cycle.

摘要: . Evidence in favour of labelling DNA excess requirements for mitosis was found adult organs showing no (heart muscle and brain), with low mitotic indexes (liver, seminal vesicle) and, more recently, the small intestine rodents, bone formation growing roots Vicia faba. A survey published data showed higher than would be expected from S, M tc deducted labelled mitoses curves. to improve accuracy needed a complete assessment duration (M) proportion cells which are longer cycle crypts were determined using Colcemid. fact that all villi derived there is cell-loss checked by cell-counts. The results show 3040%of nuclei jejunum mice at 1 hr after injection 3H-thymidine do not proceed mitosis. The last interpreted as metabolic necessary function differentiated villi. There some evidence processes might lost
