Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Local skin glucocorticoid production is crucial for healthy skin, and its disruption can lead to skin diseases.
