Exosomes from hair stem cells can reduce skin aging from UVB exposure.

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

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.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

Conditioned media from human amniotic fluid-derived stem cells helps skin heal and protects against aging from sun exposure.

Stress hormone stops a growth signal and keeps hair stem cells inactive, reducing hair growth.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Apple stem cell extract may increase the number of stem cells in a part of the hair follicle.

Fat-derived stem cells may help treat skin aging and hair loss.

Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.

Removing a key gene in mice leads to premature aging and loss of stem cells.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

Stuff from umbilical cord stem cells helps skin heal and look younger.

Adipose stem cell-derived exosomes may improve hair count and scalp health, potentially outperforming current treatments like minoxidil.

Vav2 changes how hair follicle stem cells' genes work as they age, which might improve regeneration but also raise cancer risk.

Adipose Stem Cell-derived Exosomes (ASCE) could potentially be used for hair loss treatment and scalp rejuvenation, as they have shown to increase hair length, thickness, and count, and improve conditions like androgenic alopecia and alopecia areata.

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.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

Hair graying happens because certain cells aren't maintained properly.

RT1640 treatment reverses gray hair and promotes hair growth in mice.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.
