TLDR 3D skin bioprinting, using skin bioinks like collagen and gelatin, is growing fast and could help treat wounds, burns, and skin cancers, as well as test cosmetics and drugs.
The study analyzed granted patents for skin bioinks intended for 3D skin bioprinting from 2017 to 2022. The search yielded 550 patents, of which 45 were included in the analysis. The patent applications were filed by nine countries, with South Korea (20) and China (15) filing the most. The most common materials used in a hydrogel composition were collagen (13) and gelatin (8). The skin bioinks were intended for use in vivo (24), in vitro (12), or both (5). The study concludes that 3D skin bioprinting is expected to rapidly expand in the near future and could be beneficial for a range of conditions, including chronic wounds, burns, and skin cancers. Skin bioinks could also be used for in vitro cosmetics, drug, and toxicity testing.
