The assessment of post mortem PCNA+ cell frequency in the rat epidermis
1Department of Histology and Embryology, Medical University, Lódź, Poland.
Abstract:
PCNA-positive nuclei (nPCNA+) in the basal layer of rat epidermis were assessed in the period of 0-19 days after death. The PCNA+ nuclei were present in this layer up to 12th day. The decrease in PCNA+ nuclei ratio was highly correlated with the time and followed the equation y = a + b square root(x) (y = nPCNA fraction, x = time post mortem).
