Intensity of RNA and protein synthesis in fibroblasts during wound healing in mice
RNA and protein synthesis in fibroblasts was studied by a double-labeling method on the 3rd and 7th days of wound healing in mice by electronmicroscopic autoradiography. The ratio of protein synthesis in the cytoplasm and RNA synthesis in the nucleus was shown to differ significantly in individual cells, with the result that fibroblasts with relative predominance of one of the two types of synthesis were found at both stages of wound healing. On average fibroblasts showed a higher level of protein synthesis on the 3rd day of healing. This high mean level was maintained by an increase in the proportion of fibroblasts in which protein synthesis predominated over RNA synthesis.
