Epidermal stem cells use integrin β1 and α6 as markers and CD271+ cells help maintain skin health and heal wounds.

Human sweat glands have a type of stem cell that can grow well and turn into different cell types.

Keratinocytes and adipose-derived stem cells can effectively heal difficult skin wounds.

Freezing and storing special stem cells from hair follicles keeps their ability to grow hair and turn into different cell types.

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

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Fat-derived stem cells and their secretions show promise for treating skin aging and hair loss.

Rat whisker cells can help turn other cells into nerve cells and might be used to treat brain injuries or diseases.

Substances from dental stem cells might help treat hair loss.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

In vivo lineage labelling is better than in vitro methods for identifying and understanding stem cells.

Nrf-2-modified stem cells from hair follicles significantly improve ulcerative colitis in rats.

The new microwell device helps grow more hair stem cells that can regenerate hair.

Androgen is important in controlling stem cell differentiation, reducing fat development, and increasing lean mass.

Both human platelet lysate and minoxidil can promote hair growth, but they affect different genes and cell survival rates.

Glycyrrhizic acid and licorice extract can significantly reduce unwanted hair growth.

Valproic Acid helps regrow hair in mice and activates a hair growth marker in human cells.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Transplanted whisker follicles caused hair growth on the spine of mice.

Activating TRPMLs helps human cells important for hair growth and increases hair growth in mice.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Topical drugs and near-infrared light therapy show potential for treating alopecia.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Two drugs, tofacitinib and ruxolitinib, may help regrow hair by activating hair follicles.

The book "Hair Follicle Regeneration" discusses the potential of regenerating human hair follicles or activating dormant ones as a possible cure for baldness, and the promising role of new technologies like 3D printing in this field.

The new method can create hair follicle-like structures but not complete hair with roots and shafts, needing more improvement.

Old hair follicles grew better when moved to a young environment.

Baicalin may help treat hair loss by promoting hair follicle growth and activating specific cellular pathways.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.
