Developing hair follicles form from ring-shaped patterns, with future stem cells originating from the outer ring, not the upper layers, as previously thought.

Keratins provide structural strength in epithelial cells and help identify cell origins.

Sweat gland stem cells help maintain glands, aid wound healing, and can regenerate skin structures.

Mouse stem cells from hair follicles can improve wound healing and reduce scarring.

Epidermal stem cells show promise for treating orthopedic injuries and diseases.

Rat vibrissae structure relates to their sensory function.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

Rat vibrissae have sensory terminals with specific structures that help detect hair movements.

Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.

Steroids affect skin health and healing, offering new treatment options.

Scarring alopecia affects different hair follicle stem cells than nonscarring alopecia, and the infundibular region could be a new treatment target.
