Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.

Hair loss in middle-aged women is often linked to insulin resistance and a family history of hair loss, particularly from their fathers.

There are two types of stem cells in rodent hair follicles, each with different keratin proteins.

Researchers developed a 3D model of human hair follicle cells that can help understand hair growth and test new hair loss treatments.

Scientists discovered that certain stem cells from mice and humans can be used to grow new hair follicles and skin glands when treated with a special mixture.

TGFβ signaling prevents sebaceous gland cells from producing fats.

Epidermal Growth Factor helps hair follicle cells grow and move by activating a specific cell signaling pathway.

The research found that polycystic ovary syndrome (PCOS) has two distinct types, with one having more severe hormone and insulin issues.

CRAC channels are crucial for the development and function of specialized immune cells, preventing severe inflammation and autoimmune diseases.

Hair follicle regeneration in skin grafts may be possible using stem cells and tissue engineering.

New treatments targeting skin stem cells show promise for skin repair, anti-aging, and cancer therapy.

Stress can cause early aging in certain skin cells, leading to problems with hair growth.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Human skin can provide stem cells for tissue repair and regeneration, but there are challenges in obtaining and growing these cells safely.

Hair restoration surgery effectively treats hair loss with natural-looking results, using techniques like stem cells and platelet-rich plasma.
