Hair follicle bulge cells don't help skin regrow after glucocorticoid damage; interfollicular epidermis cells do.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

Notch signalling helps skin cells differentiate and prevents tumors.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

The conclusion is that FFA and LPP have similar scalp biopsy features, making them hard to distinguish histologically, and FFA may be a specific kind of scarring hair loss.

EGFR is essential for normal hair development and follicle differentiation.

Scientists created stem cells that can grow hair and skin.

Injecting CD34+ cell-containing platelet-rich plasma into the scalp can improve hair count and thickness in people with pattern hair loss.

Retinoic acid-binding proteins in skin are regulated by β-catenin and Notch signalling.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

Minoxidil foam enters hair follicles and skin for hair growth.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

Parathyroid hormone-related protein helps control hair growth phases in mice.

Retinoic acid production and signaling in hair follicles are regulated by location and timing, affecting hair growth and cycling.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Psoriasis can cause temporary or permanent hair loss.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Polarized dermoscopy is slightly better than nonpolarized for diagnosing hair disorders, with each method having its own strengths.

Human hair follicle dermal cells can effectively replace other cells in engineered skin.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

The document suggests that certain protein deficiencies and scalp blistering in Epidermolysis Bullosa may cause hair loss.

The gene Msx2 is crucial for hair follicle regeneration during wound healing.

The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

Hair follicles significantly affect the skin absorption of some drugs.

Keratinocytes from dog hair follicles can create a functional skin layer in a lab model, useful for dog skin therapy.
