Cytology can identify the cell types involved in the disease process to decide if the skin condition is inflammatory or neoplastic, as well as the presence of bacteria and yeast.Mar 2, 2019.
Here, using genetic mouse models of nevi 2,3, we show that dermal clusters of senescent melanocytes drive epithelial hair stem cells to exit quiescence and change their transcriptome and composition, potently enhancing hair renewal.
Nevus melanocytes activate a distinct secretome, enriched for signalling factors.
Knowledge of hair follicle structure and the hair cycle is vital in the understanding of hair disorders. There are three distinct phases of the hair cycle:
