Some patients taking finasteride or dutasteride may have ongoing sexual problems and depression even after stopping the medication.

ATP-dependent chromatin-remodeling complexes are crucial for gene regulation, cell differentiation, and organ development in mammals.

Stem cell niches support, regulate, and coordinate stem cell functions.

TGF-β is crucial for controlling stem cell behavior and changes in its signaling can lead to diseases like cancer.

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

Stem cell self-renewal is complex and needs more research for full understanding.

Aging causes skin stem cells to work less effectively.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

Key genes and factors crucial for hair follicle development and wool traits in Merino sheep were identified.

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

Skin-derived precursors in hair follicles come from different origins but function similarly.

Removing both Atr and Trp53 genes in adult mice causes severe tissue damage and death due to DNA damage.

The Wnt/β-catenin pathway is important for tissue development and has potential in regenerative medicine, but requires more research for therapeutic use.

Conditioned media from mesenchymal stem cell cultures could be a more effective alternative for regenerative therapies, but more research is needed.

Skin development in mammals is controlled by key proteins and signals from underlying cells, involving stem cells for maintenance and repair.

Certain genes control the color of human hair by affecting pigment production.

5α-reductase inhibitors can cause sexual problems, higher risk of aggressive prostate cancer, and depression.

Disrupting the Sox21 gene in mice causes hair loss and regrowth cycles.

Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.

New LPA receptors (LPA4, LPA5, LPA6) have diverse roles in the body.

SDF-1/CXCL12 and its receptor CXCR4 are crucial for melanocyte movement in mouse hair follicles.

β-catenin, Shh, and Bmp signaling control hair follicle development.

High proliferation and cell delamination drive early skin development, while later stages may not rely on cell division orientation.

Wnt signaling is important for development and cell regulation but can cause diseases like cancer when not working properly.

3,4,5-tri-O-caffeoylquinic acid promotes hair growth by activating the β-catenin pathway.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

Adult skin quickly reacts to short-term environmental and internal stress, leading to various skin issues and the need for protective measures.
