The skin has a complex immune system that is essential for protection and healing, requiring more research for better wound treatment.

Scientists made working salivary glands in mice using bioengineered cells, which could help treat dry mouth.

Chitosan/LiCl composite scaffolds help heal deep skin wounds better.

Mesenchymal stem cells, especially injected into the skin, heal wounds faster and better than chitosan gel or other treatments.

Stem cell therapies show promise for treating various diseases but face challenges in clinical use and require better monitoring techniques.

Human fetal placental stromal cell injections speed up healing and improve skin and hair recovery after radiation damage.

3D-printed membranes with smart sensors can greatly improve tissue healing and have many medical applications.

Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.

Applying a special compound can promote hair growth without harmful side effects.

Alkylation of human hair keratin allows for adjustable drug release rates in hydrogels for medical use.

Keratins are important for skin cell health and their problems can cause diseases.

The 3D scaffold helped maintain hair cell traits and could improve hair loss treatments.

MMP-2 and MMP-9 help hair grow, while their inhibitors peak when hair growth slows.

Small molecule IM boosts hair growth by changing stem cell metabolism.

The osteopontin gene is active in a specific part of rat hair follicles during a certain hair growth phase and might affect hair cycle and diseases.

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

The composite sponge helps heal diabetic wounds by reducing inflammation and promoting new blood vessel growth.

Magnesium Silicate Sprays help heal burn wounds and regrow skin features better than commercial products.

Epidermolysis bullosa simplex causes easily blistered skin due to faulty skin cell proteins, leading to new treatment ideas.

A special stem cell fluid can speed up wound healing and hair growth in mice.

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

Jagged-1 in skin Tregs is crucial for timely wound healing by recruiting specific immune cells.

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.

Wnt and Notch signaling help wound healing by promoting cell growth and regulating cell differentiation.
