    Studysummary This study observed that in androgenetic alopecia patients, the expression of CD34+ progenitor cells significantly decreased in frontal scalp biopsies, while Sox9 expression remained consistent, suggesting that altered conversion of hair follicle stem cells to progenitors may significantly contribute to AGA development.
