More dermal papilla cells in hair follicles lead to larger, healthier hair, while fewer cells cause hair thinning and loss.

The best method for urethral reconstruction is using hypoxia-preconditioned stem cells with autologous cells on a vascularized synthetic scaffold.

Three specific proteins can turn adult skin cells into hair-growing cells, suggesting a new hair loss treatment.

Coating surfaces with human hair keratin improves the growth and consistency of important stem cells for medical use.

Using a drug to activate bone marrow stem cells can help the liver regenerate and function better after major surgery in rats.

Operative hysteroscopy is still the main treatment for Asherman syndrome, but more research is needed on post-surgery methods.

Electrospun scaffolds can improve healing in diabetic wounds.

Colostrum-derived exosomes can promote hair growth and may be a promising treatment for hair loss.

Cell polarity signaling controls tissue mechanics and cell fate, with complex interactions and varying pathways across species.

Researchers created a potential skin substitute using a biodegradable mat that supports skin cell growth and layer formation.

Stem cells could potentially rebuild missing structures in wounds, improving facial skin replacement techniques.

Communication between blood vessel and hair follicle cells decreases with age, affecting hair growth and blood vessel formation.

The CuCS/Cur wound dressing helps regenerate nerves and heal deep skin burns by rebuilding hair follicles.

The gene Tfap2b is essential for creating a type of stem cell in zebrafish that can become different pigment cells.

ATP-dependent chromatin remodeling is crucial for skin development and stem cell function.

New regenerative treatments for hair loss show promise but need more research for confirmation.

Special proteins are important for skin balance, healing, and aging, and affect skin stem cells.

Targeting the HEDGEHOG-GLI1 pathway could help treat keloids.

A new vaccine using a porous scaffold boosts immunity and protects against the flu better than traditional methods.

Hyaluronic acid and versican are important for skin healing and hair growth and might help in regenerative medicine.

Epigenetic factors play a crucial role in skin health and disease.

High DHA levels delay wound healing and worsen skin repair quality.

Adult esophageal cells can start to become like skin cells, with a key pathway influencing this change.

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

Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.

Stress hormone corticosterone blocks a growth factor to slow down hair stem cell activity and hair growth.

Prostaglandin D2 blocks new hair growth after skin injury through the Gpr44 receptor.

EdnrB signaling helps melanocyte stem cells regenerate and could be targeted to treat pigmentation issues.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Certain human skin cells marked by CD44 and ALDH are rich in stem cells capable of long-term skin renewal.
