The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

A new microneedle patch made from hair proteins helps regrow hair faster and better than current treatments.

Regulatory T-cells are important for healing and regenerating tissues in various organs by controlling immune responses and aiding stem cells.

The PDGF/PDGFR pathway is a potential drug target with mixed success in treating various diseases, including some cancers and fibrosis.

Special fiber materials boost the healing properties of certain stem cells.

New effective scar treatments are urgently needed due to the current options' limited success.

Isotretinoin is highly effective in treating severe acne, rosacea, and gram-negative folliculitis.

Different types of skin cells have unique genetic markers that affect how likely they are to spread cancer.

Telocytes might help with skin repair and regeneration.

Blocking JAK-STAT signaling can lead to hair growth.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

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.
