BMP2 needs periosteal tissue to help regenerate mouse middle finger bones within a specific time.

Using polyethylenimine-DNA to deliver the hTERT gene can stimulate hair growth and may be useful in treating hair loss, but there could be potential cancer risks.

Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.

Insect wax, especially its policosanol content, may help hair regrow by changing hair follicle phases and increasing nutrient supply.

Balding and low testosterone increase risk of urinary stones.

Mechanical forces are crucial for shaping cells and forming tissues during development.

The document concludes that treatments for cicatricial alopecia are not well-supported by evidence, but hair transplantation shows more predictable and satisfactory results.

Peps help Arabidopsis plants grow more root hairs by affecting specific genes and calcium signaling.

Biomaterials with MSC-derived substances could improve tissue repair and have advantages over direct cell therapy.

Wnt activation shows promise for regenerative medicine but requires selective targeting to minimize risks like cancer.

The gelatin/β-TCP scaffold with nanoparticles improves wound healing and skin regeneration.

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.
