Scientists developed tools to observe hair regeneration in real time and assess skin health, using glowing mice and light-controlled genes.

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

A young man was unexpectedly diagnosed with basal cell carcinoma after a scalp examination and confocal microscopy.

Skin stem cells help repair damage and maintain healthy skin.

Scientists grew hair follicles from mouse stem cells in a lab setting.

Human dermal fibroblasts are the main cells targeted by a virus that can cause a deadly skin cancer, and a certain inhibitor can effectively block this infection.

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.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Stem cell treatments may improve burn wound healing.

Scientists created keratinocyte cell lines from human hair that can differentiate similarly to normal skin cells, offering a new way to study skin biology and diseases.

Indian Hedgehog helps control skin cell growth and protects against aggressive skin cancer.

Maintaining natural oxygen levels is crucial for healthy skin cells and effective treatments.

Middle-aged skin shows aging signs, and quercetin might help delay them.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Ancestry affects skin healing, with non-Hispanic Black patients showing more healing-related fibroblasts than White patients.

CD4+ skin cells may be precursors to basal cell carcinoma.

The combined stem cell secretome in the skin care product effectively reduces inflammation and promotes tissue regeneration.

Radiotherapy can cause skin fibrosis, which is often overlooked and needs better treatment and evaluation.

Keratin 15 helps maintain skin cell growth and repair.

Combining stem cells and organoids could improve skin regeneration treatments.

The article concludes that creating a detailed map of normal human skin at the single-cell level is important.

Boosting HGF signaling could improve the creation of hair follicles in lab-made skin.

Phospholipase Cδ1 is crucial for normal skin and hair development.

Abnormal ECM and immune cell interactions can cause skin diseases.

Hair follicle regeneration needs special conditions and young cells.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Epigenetic and metabolic changes affect stem cell function and aging in skin.

Sorafenib causes skin reactions by increasing the number and activity of skin mast cells.
