The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

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

K6hf is a unique protein found only in a specific layer of hair follicles.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

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.

Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Men generally have more severe COVID-19 cases and higher death rates than women due to biological differences.

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

MicroRNA-302 helps improve the conversion of body cells into stem cells by blocking NR2F2.

Different PIN proteins affect plant root hair growth by changing how auxin is transported.

The article concludes that the wool follicle is a valuable model for studying tissue interactions and has potential for genetic improvements in wool production.

The research found that Atypical Progeroid Syndrome has unique symptoms and is not caused by the buildup of a certain mutant protein.

Men, especially older ones with health issues like prostate cancer, may have worse COVID-19 outcomes and could benefit from therapies targeting male hormones.

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.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

A genetic region near the PAX1 gene is linked to a higher risk of scoliosis in females.

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

Thymus transplantation successfully restored immune function in infants with FOXN1 deficiency.

One minoxidil-sensitive potassium channel exists in human hair follicles.

Scientists created stem cells that can grow hair and skin.

Hair follicles are hormone-sensitive and involved in growth and other functions, with potential for new treatments, but more research is needed.

Sensitive skin is often caused by nerve fibers and environmental factors, and can be managed with mild skincare and professional advice.

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

All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.

A new mutation in the human glucocorticoid receptor reduces its function and causes resistance to glucocorticoids.

The EDAR gene greatly affects hair thickness in Asian populations.
