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

Cyclosporin A and FK506 can start new hair growth in mice, but ascomycin and rapamycin cannot.

Active oxygen scavengers can reverse the suppression of hair cell growth caused by androgens.

Mouse hair cells respond to male hormones by growing less, and this can be stopped by certain blockers.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Improving artificial vascular grafts requires better materials and surface designs to reduce blood clotting and support blood vessel cell growth.

Targeting colon cancer stem cells might lead to better treatment results.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Melanocyte stem cells in hair follicles are key for hair color and could help treat greying and pigment disorders.

Certain cells from hair follicles can create new hair and contribute to hair growth when implanted in mice.

Sebocytes play a key role in controlling androgen levels in human skin.

Skin cells produce and activate vitamin D, which regulates skin functions and supports hair growth.

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Vitamin D and its receptor regulate skin functions like cell growth, immunity, hair cycle, and tumor prevention.

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

The enzyme 25 Hydroxyvitamin D 1 α-Hydroxylase is essential for healthy skin and recovery after skin damage.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Hibiscus rosa-sinensis leaf extract helps hair grow longer and faster.

Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.

Cytokeratin 19 and cytokeratin 15 are key markers for monitoring the quality and self-renewing potential of engineered skin.

Blocking the Wnt pathway could lead to new treatments for cancer and tissue repair but requires careful development to avoid side effects.

Melatonin helps regulate hair growth and protects the hair follicle from stress.

Notch/CSL signaling controls hair follicle differentiation through Wnt5a and FoxN1.

Newborn mouse skin cells can grow hair and this process can be recreated in adult cells to potentially help with hair loss.

Using human fat tissue derived stem cells in micrografts can safely and effectively increase hair density in people with hair loss.

Scientists made the first metal-based compounds from a nonsteroidal antiandrogen drug, which showed potential in fighting both hormone-dependent and independent prostate cancer cells.
