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.

Probiotic bacteria improved skin and hair health in aged mice.

Stress can stop hair growth in mice, and treatments can reverse this effect.

Stem cell plasticity is crucial for wound healing but can also contribute to cancer development.

Male pattern baldness involves hormones and cell signals affecting hair growth.

The document concludes that while significant progress has been made in understanding skin biology and stem cells, more research is needed to fully understand their interactions with their environment.

Macrophages help regrow hair by activating stem cells using AKT/β-catenin and TNF.

Trilostane effectively and safely treats dogs with pituitary-dependent hyperadrenocorticism, improving symptoms and adrenal gland size.

Hair loss occurs due to fewer papillary cells, smaller follicles, and shorter growth phases.

Liposomes could improve how skin care products work but are costly and not very stable.

Minoxidil is the only FDA-approved topical drug for treating male or female pattern hair loss, and other medications like finasteride and dutasteride can also increase hair growth.
