Comparison between nuclear chromatin patterns of digitalized images of cells of the mammalian testicular and renal tissues: an imaging segmentation study.

Testicular and renal tissue, obtained from adult cattle, pigs, rats, and human was processed by image digital segmentation and pixel texture analytical techniques for comparative evaluation of nuclear chromatin pattern of testicular primary spermatocytes and renal glomerular endothelial cells. The post mortem performed for the animals and the human subject were for reasons not related with either testicular or renal conditions. The objective was to establish a benchmark for identification of rapidly multiplying cells in images of sections of normal, as well as abnormal mammalian tissue. Based on the observed morphological and texture pattern of the nuclear chromatin of the testicular primary spermatocytes, it was determined that the renal glomerular endothelial cells exhibit similar nuclear chromatin morphology consistent with an ongoing rapid multiplication process. The nuclear chromatin of both cell types manifest identical mitotic figures which are strongly indicative of cellular proliferation.
