Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Sox2-positive dermal papilla cells have unique characteristics and contribute more to skin and hair follicle formation than Sox2-negative cells.

The WNT signaling pathway is important in many diseases and targeting it could offer new treatments.

Mammals might fail to regenerate not because they lack the right cells, but because of how cells respond to their surroundings, and changing this environment could enhance regeneration.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Cellular senescence has both cancer-blocking and cancer-promoting effects, and targeting senescent cells may improve health and lifespan.

Fat cells are important for healthy skin, hair growth, and healing, and changes in these cells can affect skin conditions and aging.

Human hair follicle stem cells can be turned into red blood cells.

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

Hair follicle stem cells are promising for blood vessel formation and tissue repair.

The synthetic retinoid EC23 thickens skin and promotes hair growth more effectively and with a lower dose than natural retinoids.

The conclusion is that genetic differences affect how the cochlea heals after hair cell loss, which may challenge the creation of hearing loss treatments.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Researchers found 63 genes linked to male-pattern baldness, which could help in understanding its biology and developing new treatments.

Zebrafish need MYC and FGF to regenerate inner ear hair cells.

Th22 cells are essential for Tβ15-induced hair growth in mice.

Tiny particles from 3D-grown skin cells speed up wound healing by promoting blood vessel growth.

The conclusion is that accurately replicating the complexity of the extracellular matrix in the lab is crucial for creating realistic human tissue models.

New treatments for skin damage from UV light using stem cells and their secretions show promise for skin repair without major risks.

Adding insulin-like growth factor 1 and bone marrow-derived stem cells to a collagen-chitosan scaffold helps wounds heal faster and regrows hair follicles.

Baricitinib and its combination with lonafarnib improve fat cell formation in certain genetic disorders.

Melatonin, usually known for sleep regulation, also has antioxidant properties that can protect skin, stimulate hair growth, and improve skin conditions, with topical application being more effective than oral use.

Wnt/β-catenin signaling is important for keeping skin cell attachment structures stable.

Fibroblast Growth Factors (FGFs) are important for tissue repair and regeneration, influencing cell behavior and other factors involved in healing, and are crucial in processes like wound healing, bone repair, and hair growth.

Radiation therapy damages skin structure and immune function, causing inflammation and potential hair loss.

The Hedgehog Signaling Pathway is important for skin and hair development and skin cancer treatment, but more research is needed to understand it fully.

Vitamin A is important for healthy skin and hair, influencing hair growth and skin healing, but UV light reduces its levels.

Regenerative medicine shows promise for improving hair and skin but needs more research for standard use.

Exosome therapy shows promise for treating skin conditions and improving wound healing.

The method can test hair growth products using a lab-made hair-like structure that responds to known treatments.
