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.

Surgeons must understand the full care process for gender confirmation surgery to help transgender individuals effectively.

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

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Formyl-peptide receptor agonists could be new anti-inflammatory drugs.

MicroRNA-214 is important for skin and hair growth because it affects the Wnt pathway.

Different soft tissue fillers can cause various skin reactions; biodegradable fillers are safer and non-biodegradable ones like silicone can lead to long-term problems.

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

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

New antifungal treatments for a children's scalp infection are effective and safe, but it's not decided if they will become the preferred option over the old treatment.

Women with PCOS may take longer to get pregnant but can have a normal family size, and should manage their overall health to reduce long-term health risks.

Older adults have a high rate of skin cancers like basal cell carcinoma and melanoma, mainly due to UV exposure and age.
