Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.

Obese mice with a leptin gene mutation have a longer resting phase in their hair cycle, which may help understand certain hair loss conditions.

New technique implants pigment in scalp with less pain and damage.

Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

Hair quality is genetically determined and linked to its composition and strength.

The pituitary gland functions normally even after losing most SOX2+ stem cells.

Fat-related cells are important for initiating hair growth.

SKPs are similar to adult skin stem cells and could help in skin repair and hair growth.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Wnt ligands are crucial for hair growth and repair.

4D polycarbonate scaffolds show promise for soft tissue repair due to their biocompatibility, shape memory, and minimal immune response.

Blocking β-catenin in skin cells improves hair growth during wound healing.

Oncogenic melanocyte stem cells can develop into melanoma similar to human cases.

Scientists successfully created and transplanted bioengineered hair follicles that function like natural ones, suggesting a new treatment for hair loss.

Hair can regrow after certain stem cells are lost because other stem cells can take over their role.

Mutations in the hairless gene in mice affect its expression and lead to a range of developmental issues in multiple tissues.

Activating Notch in adult skin causes T cells and neural crest cells to gather, leading to skin issues.

Mice can correct hair follicle orientation without certain genes, but proper overall alignment needs those genes.

Senescent melanocytes can boost hair growth by activating hair stem cells.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Dying cells can help with faster healing and new hair growth by releasing a growth-promoting molecule.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

The guide explains how to study human skin fat cells and their tissue, aiming to improve research and medical treatments.

A rare gene variant causes hair and nail issues in a family.

Male rats have more somatostatin neurons than females due to testosterone converting to estrogen during early development.

The microneedle arrays effectively promote wound healing and have potential for clinical use.

Blocking 5α-reductase can harm memory and brain structure, and increase harmful brain changes in male mice used for Alzheimer's disease research.

The study concluded that hair growth in mice is regulated by a stable interaction between skin cell types, and disrupting this can cause hair loss.

A gene deletion in mice causes weak protein, immune issues, hair loss, airway problems, and wasting disease.

Eating selenium-rich rice improved antioxidant activity and signs of aging in mice.
