Bioprinting is improving skin models for better testing of skin diseases without using animals.

In vitro skin models are improving but still need more innovation to fully replicate human skin.

Conditioned medium from keratinocytes can improve hair growth potential in cultured dermal papilla cells.

Nanoplastics can penetrate skin cells, triggering inflammation and immune responses.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

Hydrogels can enhance stem cell activity, but more research is needed to optimize their use.

Engineered skin tissue is a promising tool for safer cosmetic testing.

Blue light therapy is safe for skin and may protect against UV radiation.

Functionalized hydrogels can help heal tissues and fight infections by delivering beneficial bacteria and antimicrobials.

Using Matrigel with stem cells improves tissue healing.

3D bioprinting shows promise for better skin regeneration by creating structures similar to natural skin.

Progesterone reduces anxiety and depression in female mice by increasing BDNF in the brain, needing 5α-reduction and estradiol.

3D models and organoids improve liposarcoma research and therapy development.
