Concentrated nanofat helps mice grow hair by activating skin cells and may be used to treat hair loss.

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

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

Researchers successfully grew hair follicle stem cells from mice and humans, which could be useful for tissue engineering and regenerative medicine.

Inactive hair follicle stem cells help prevent skin cancer.

Hair growth environment recreated with challenges; stem cells make successful skin organoids.

Androgen is important in controlling stem cell differentiation, reducing fat development, and increasing lean mass.

Fully regenerating human hair follicles not yet achieved.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

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

Different types of skin cells play specific roles in development, healing, and cancer.

Stem cells, especially from fat tissue and Wharton's jelly, can potentially regenerate hair follicles and treat hair loss, but more research is needed to perfect the treatment.

Regenerative therapies show promise for treating vitiligo and alopecia areata.

Stem cell therapy shows promise for hair loss treatment, but more research is needed to confirm its effectiveness.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Improving dermal papilla cells can help regenerate hair follicles.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

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

Understanding how hair follicle stem cells work can help find new ways to prevent hair loss and promote hair growth.

Changing the environment around stem cells could help tissue repair, but it's hard to be precise and avoid side effects.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

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

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

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Hair follicles are valuable for regenerative medicine and wound healing.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

Fibroblasts, cells usually linked to tissue repair, also help regenerate various organs and their ability decreases with age. Turning adult fibroblasts back to a younger state could be a new treatment approach.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

Mice lacking the PPARγ gene in their fat cells had almost no fat tissue, severe metabolic problems, and abnormal development of other fat-related tissues.

The review concluded that keeping the hair-growing ability of human dermal papilla cells is key for hair development and growth.
