Platelet-rich plasma (PRP) is a natural healing substance in our blood. This study explores ways of enhancing the wound healing process. It can be done through extracting PRP from the blood of a patient with a complex skin wound. 3D printing can manipulate it to form an implant for tissue repair. Above all, difficult-to-heal skin wounds would be able to treat with this in a single surgical procedure.
In conclusion, the results showed that application of the 3D-printed PRP implant helped to speed up the healing of the wound. This is by enabling efficient vascularisation (meaning development of new blood vessels) and inhibiting fibrosis (scarring/thickening of tissue). For effective wound healing, both of these are essential.
