Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

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

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

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

Compartmentalized organization might be crucial for stem cells to effectively respond to growth or injury.

Premature graying of hair may suggest health issues and currently lacks effective treatments.

The document concludes that understanding how adult stem and progenitor cells move is crucial for tissue repair and developing cell therapies.

Blocking interferon-gamma might help treat various autoimmune diseases.

The study showed that some hair follicle stem cells wake up to grow hair while others stay asleep, and that the environment around them is important for hair growth.

Stem cells regenerate tissues and their behavior varies by environment, suggesting the hematopoietic system model may need revision.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

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

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.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Dogs could be good models for studying human hair growth and hair loss.

Epidermal stem cells have various roles in skin beyond just maintenance, including forming specialized structures and aiding in skin repair and regeneration.

Royal jelly can protect the heart from damage caused by paclitaxel.

Lack of Ctip2 in skin cells delays wound healing and disrupts hair follicle stem cell markers in mice.

Estrogen can temporarily slow down hair growth but this can be reversed.

CRISPR/Cas9 gene-editing shows promise for improving sheep and goat breeding but faces challenges with efficiency and accuracy.

Wounded skin cells can revert to stem cells and help heal.

EGFR helps control how hair grows and forms without needing p53 protein.

Astaxanthin may improve health by reducing inflammation, stress, and cholesterol, and by enhancing skin health and sports performance.

Intermediate filaments are crucial for cell differentiation and stem cell function.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

Hair follicle stem cells from Arbas Cashmere goats can become fat, nerve, and liver cells.

Epithelial stem cells can adapt and help in tissue repair and regeneration.

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.
