Layer-by-Layer self-assembly is promising for biomedical uses like tissue engineering and cell therapy, but challenges remain in material safety and process optimization.

New methods to improve the healing abilities of mesenchymal stem cells for disease treatment are promising but need more research.

Different species and human skin models vary in their skin enzyme activities, with pig skin and some models closely matching human skin, useful for safety assessments and understanding the skin's protective roles.

Facial plastic surgery has evolved to focus on less invasive techniques and innovative technologies for cosmetic and reconstructive procedures.

Activating β-catenin in certain skin cells speeds up hair growth in mice.

3D bioprinting in plastic surgery could lead to personalized grafts and fewer complications.

The new 3D bioprinting method successfully regenerated hair follicles and shows promise for treating hair loss.

Wnt proteins from certain skin cells are crucial for normal hair growth and renewal.

Fat grafting reduces scar fibrosis but may slow skin healing.

Hydrogels combined with extracellular vesicles and 3D bioprinting improve wound healing.

3D-printed microneedles improve drug delivery and diagnostics but face scalability and regulatory challenges.

3D printed microneedles are likely to become more common in cosmetics for better skin delivery.

Keratin hydrogels from human hair show promise for tissue engineering and regenerative medicine.

The research showed that Vitamin D and its receptor are important for healthy bones and normal hair and skin in rats.

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

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

Stem cells and their surrounding environment in hair follicles work closely together, affecting hair growth and having implications for cancer and tissue regeneration.

Skin cells can help create early hair-like structures in lab cultures.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Gene network oscillations inside hair stem cells are key for hair growth regulation and could help treat hair loss.

Human mesenchymal stem cells can become dermal papilla cells, aiding hair growth.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

Pantothenic acid helps mink hair follicles grow by affecting certain cell signals.

Certain genes are more active in baby scalp cells and can help grow hair when added to adult mouse skin cells.

Hdac1 and Hdac2 help maintain and protect the cells that control hair growth.

Electrospun 3D nanofibrous materials show promise for bone regeneration in orthopaedics.

Human stem cells were turned into cells similar to those that help grow hair and showed potential for hair follicle formation.

Scientists successfully grew mini hair follicles using human skin cells, which could help treat baldness.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
