Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

MSC-derived exosomes can help treat COVID-19, hair loss, skin aging, and arthritis.

Disrupted cholesterol production impairs hair follicle stem cells, leading to hair loss.

Hair follicle stem cells in hairpoor mice are disrupted, causing hair loss.

The secretions of mesenchymal stem cells could be used for healing without using the cells themselves.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

The research found that different types of fibroblasts are involved in wound healing and that some blood cells can turn into fat cells during this process.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Lactate production is important for activating hair growth stem cells.

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

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

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

Interferon, especially alfa interferon, is an effective treatment for cutaneous T-cell lymphoma with manageable side effects.

The conclusion is that hair growth can be improved by activating hair cycles, changing the surrounding environment, healing wounds to create new hair follicles, and using stem cell technology.

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

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

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

Stem cells help repair tissue mainly by releasing beneficial substances, not by replacing damaged cells.

Researchers created rat liver stem cells that could help repair liver failure in rats and may be useful for studying human liver diseases.

Fat cells are important for tissue repair and stem cell support in various body parts.

Peptide hydrogel scaffolds help grow new hair follicles using stem cells.

PBX1 helps hair stem cells grow and change by turning on certain cell signals and preventing cell death, which may be useful for hair regrowth treatments.

The environment around melanocyte stem cells is key for hair regeneration and color, with certain injuries affecting hair color and potential treatments for pigmentation disorders.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

HPV16 oncogenes disrupt the normal activity of hair follicle stem cells.

Understanding hair follicle biology and stem cell control could lead to new hair loss treatments.

3D cell-derived matrices improve tissue regeneration and disease modeling.

The conclusion is that teeth, hair, and claws have similar stem cell niches, which are important for growth and repair, and more research is needed on their regulation and potential markers.

Fetal-maternal stem cells in a mother's hair can help with tissue repair and regeneration long after childbirth.
