Fetal skin heals without scarring due to unique cells and processes not present in adult skin healing.

Platelet-rich plasma might help tissue regeneration in dentistry, but results vary and more research is needed.

Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

A certain smell receptor in hair follicles can affect hair growth when activated by a synthetic sandalwood scent.

Hidradenitis suppurativa is caused by genetic factors, inflammation, bacteria, hormones, and lifestyle factors like obesity and smoking.
