PDGF signaling is crucial for maintaining fat stem cells in the skin, and its level of activation can either preserve these cells or cause fibrosis.

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.

The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.

M-CSF-stimulated myeloid cells can turn into skin cells and help heal wounds and regrow hair.

Human dermal stem cells can become functional skin pigment cells.

Both immature and mature fat cells are important for hair growth cycles, with immature cells promoting growth and mature cells possibly inhibiting it.

ILK is essential for proper hair follicle development and structure.

A mix of specific inhibitors and a growth factor helps keep hair growth cells from losing their properties in the lab.

Changing hair follicle identity could potentially reverse balding.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

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.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

New methods for skin and nerve regeneration can improve healing and feeling after burns.

Progress has been made in skin and nerve regeneration, but more research is needed to improve methods and ensure safety.

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

Improving the environment and cell interactions is key for creating human hair in the lab.

Aconiti Ciliare Tuber extract may help hair grow by activating a specific cell signaling pathway.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

Fully regenerating human hair follicles not yet achieved.

The document concludes that while lab results for hair growth promotion are promising, human trials are needed and better testing methods should be developed.

Using certain small proteins with a growth factor and specific materials can increase the creation of neurons from stem cells.

Skin stem cells are maintained by signals from nearby cells and vary in their ability to renew and mature.

Glycyrrhizic acid may help reduce unwanted hair growth.

Aging scalp skin contributes to hair aging and loss, and more research is needed to develop better hair loss treatments.

Both human platelet lysate and minoxidil can promote hair growth, but they affect different genes and cell survival rates.

Only skin melanocytes, not other types, can color hair in mice.

Sox2 controls hair color by affecting pigment production in hair follicles.

Human hair grows better in a special gel that mimics skin.

Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.
