Fetal cells could improve skin repair with minimal scarring and are a potential ready-to-use solution for tissue engineering.

Hair restoration surgery effectively treats hair loss with natural-looking results, using techniques like stem cells and platelet-rich plasma.

The document concludes that while "hair follicle cloning" shows promise for unlimited donor hair, it faces challenges with consistency and safety in humans.

Extracellular vesicles show promise for wound healing, but more research is needed to improve their stability and production.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

Transplant success has improved with better immunosuppressive drugs and donor matching.

New cell-based therapies may improve hair loss treatments in the future.

Scientists created early-stage hairs from mouse cells that grew into normal, pigmented hair when implanted into other mice.

Bioengineering can potentially treat hair loss by regenerating hair follicles and cloning hair, but the process is complex and needs more research.

Host cells are crucial for the maturation of reconstructed hair follicles.

Intestinal stem cells can help repair skin damage from radiation.

Stem cells show promise for hair loss treatment, but no effective product for hair regeneration has been developed yet.
