Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

MCSP may help identify and regulate skin stem cells, affecting hair growth and regeneration.

The circadian clock in skin cells controls their growth and rest cycles.

Activating Sonic Hedgehog signaling in cancer stroma may help treat basal cell carcinoma.

Human hair follicle cells can be used to help heal and replace skin.

Canine hair follicles contain stem-like cells with high growth potential.

CD4+ skin cells may be precursors to basal cell carcinoma.

Sebaceous glands can form new hair follicles when activated, but hair follicle bulges cannot.

Stem cells are in deep skin layers, while differentiating cells are in shallow layers.

Nuclear shape and chromatin changes affect gene expression in skin cell differentiation.

Epidermal cysts come from the skin, while pilar cysts come from hair follicles.

Different substances affect hair and skin cell growth in various ways, with some promoting and others inhibiting cell proliferation.

ePUKs could be valuable for regenerative medicine due to their wound healing abilities.

Higher levels of nidogen1 and type IV collagen are found in basal cell carcinoma compared to normal skin.

Keratin K14 expression varies between hair follicles and epidermis, affecting cell differentiation.

Basonuclin is crucial for hair follicle development and cycling in mice.

ErbB2 signaling is crucial for skin cell growth and cancer development in mice.

A unique skin cell similar to hair bulb melanocytes was identified, with better preservation using permanganate fixation.

Dermal papilla cells help skin stem cells grow into hair.

Overexpressing GLI-1 in mice skin can cause tumors like human basal cell carcinomas.

Bikunin is found on the cell boundaries of certain skin layers and may help regulate skin and hair functions.

Matrical tumors share a common growth mechanism involving the Wnt pathway and consistent PHLDA1 expression.

MTS24 marks a new type of skin cell that helps hair growth and repair.

Keratin expression reflects cell organization and differentiation, not causes it.

Basonuclin helps identify and track hair follicle development and cycling in mice.

PmtHEE is a better model for studying pigmented skin because it includes melanocytes and shows improved cell differentiation.
