Different types of stem cells and their environments are key to skin repair and maintenance.

The research reveals how early embryonic mouse skin develops from simple to complex structures, identifying various cell types and their roles in this process.

Hair can regrow in adult mice's skin after injury, and this regrowth doesn't come from existing hair cells but from skin cells in the wound, with Wnt7a protein helping this process. This could help treat baldness and scarring.

Hair can regrow in adult mice's skin after injury, and this process can be boosted by increasing Wnt7a, a protein. This could potentially help treat baldness and change our understanding of hair growth.

Adipocytes can change into fibroblast-like cells to help with wound healing.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

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

Aging reduces skin stem cell function, leading to changes like hair loss and slower wound healing.

Hedgehog signaling in skin cells is crucial for hair growth and skin healing, but needs to be balanced to avoid harmful effects like scarring and cancer.

Mice without the p21 gene can fully regenerate injured ears due to reduced Sdf1 increase and leukocyte recruitment, suggesting new ways to induce tissue regeneration in mammals.

Krt15+ cells in the mouse intestine resist radiation and can start tumors.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

LGR5 and LGR6 are expressed differently in various skin tumors, which may offer clues about their origins.

Different types of fibroblasts play various roles in both healthy and diseased tissues, and understanding them better could improve treatments for fibrotic diseases.

Eating grape powder may reduce the severity of skin allergy symptoms.

Calcium signals and SHH guide the direction of feather growth in chicken skin.

Women with scarring alopecia are less likely to have used hormone replacement therapy or oral contraceptives compared to those with female pattern hair loss.

When skin blisters, healing the wound is more important than growing hair, and certain stem cells mainly fix the blisters without helping hair growth.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Lower proximal cup cells, not bulge stem cells, regenerate hair follicles after chemotherapy.

Hair growth and development are controlled by specific signaling pathways.

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

Different types of sun exposure damage skin cells and immune cells, with chronic exposure leading to more severe and lasting damage.

Deleting the BRD4 protein in certain skin cells causes hair loss and skin inflammation.

Mutations in the SHH pathway in certain skin cells can cause skin tumors and abnormal hair growth.

The study found that aging hair follicle stem cells change behavior, leading to hair loss, but drugs targeting these cells may help restore hair growth.

Boosting certain cell signals can prevent hair loss from chemotherapy and radiation.

Boosting certain cell signals can prevent hair loss from chemotherapy and radiation.

Blocking TSLP reduces skin inflammation and cell overgrowth in psoriasis.

Blocking cell death in certain stem cells can improve wound healing and tissue regeneration.
