TL;DR: It is shown that bulge cells in adult mice generate all epithelial cell types within the intact follicle and hair during normal hair follicle cycling and provide potential targets for the treatment of hair loss and other disorders of skin and hair.

TL;DR: It is shown that ablation of bulge cells by targeting them with a suicide gene encoding herpes simplex virus thymidine kinase leads to complete loss of hair follicles but survival of the epidermis, indicating that bulge stem cells respond rapidly to epidermal wounding by generating short-lived 'transient amplifying' cells responsible for acute wound repair.

TL;DR: It is demonstrated that bulge cells possess a stem cell phenotype characterized by their slowly-cycling nature, preferential proliferation at the onset of new hair follicle growth, high level of beta1 integrin expression, and expression of cytokeratin 19.

TL;DR: It is found that patterns of K15 expression and promoter activity changed with age and correlated with levels of differentiation within the cutaneous epithelium; less differentiated keratinocytes in the epidermis of the neonatal mouse and in the bulge area of the adult mouse preferentially expressed K15.

TL;DR: PGD2 is defined as an inhibitor of hair growth in AGA and the PGD2-GPR44 pathway is suggested as a potential target for treatment, providing new insight into the pathogenesis of AGA.
