What is a Tissue Graft?
Tissue transplantation is a technique in which autogenous tissue or artificial materials are transplanted to a part of the body to restore deformities or tissue defects caused by congenital or acquired factors.

- Defects or tissue defects caused by congenital or acquired factors can lead to dysfunction of the body. The traditional solution is autologous tissue transplantation. Although satisfactory results can be obtained, it is at the expense of autologous healthy tissue. The "Western Wall" approach will lead to many complications and additional damage.
- The filling of artificial biological materials is one of the more popular schemes at present, but the rejection response of the body to artificial materials is the first problem that needs to be solved urgently in clinical applications.
- Tissue engineering Tissue transplantation has gradually risen with the development of tissue engineering. Tissue engineering is a new medical-industrial technology developed in the 1990s. The application of this technology can form biological tissues inside and outside the body to repair human tissue defects. The advantages are:
- It can form living tissue with vitality, reconstruct the morphology, structure and function of the damaged tissue and achieve permanent replacement;
- A small amount of tissue cells can be used to repair large tissue defects to achieve minimally invasive repair and functional reconstruction;
- It can be shaped according to the tissue defect to achieve morphological repair. Although great progress has been made in tissue-engineered bone and cartilage, so far, the repair of defects with tissue-engineered bone tissue is still far from clinical requirements. The main problem is that seed cells can age after certain passages and cannot continue to proliferate, making it difficult to solve large or extra large tissue defects.
