Processing method of tissue engineered implant

Abstract

The invention discloses a disposal method for a tissue-engineered graft, comprising the following steps: (a) placing a bone graft or a cartilage graft and osteogenesis induced liquid or chondroblast induced liquid in a container for 2 hours to 14 days under 37 plus or minus 2 DEG C; (b) taking out of the bone graft or the cartilage graft from the container as the preparation material for transplant operation. The method can preserve the graft in a short term but brings no damage to the graft and keep good physical performance while the cost is low and the operation is easy.

Description

technical field [0001] The invention relates to the field of medical engineering, in particular to a method for preserving tissue engineered grafts. Background technique [0002] The industrialization of tissue engineering grafts requires the production and clinical use of large quantities of products. More importantly, when tissue defect patients urgently need tissue transplantation, it is hoped that implantable engineered products can be provided immediately. In order to shorten the time required for the construction of engineered grafts and provide replacement materials for transplanted defect tissues or parts as soon as possible, it is necessary to solve the problem of preservation of tissue engineered grafts. [0003] According to different storage temperatures, storage methods can be divided into normal temperature storage and low temperature storage. For active tissue engineering products, all biochemical reactions should be reduced or even shut down during storage, ...

Problems solved by technology

[0006] For transplants that are urgently needed, if low temperature or cryogenic storage is still used, it will not only be time-consuming, labor-intensive, and costly, but also cause damage to cells due to resuscitation and other processes
