Prepn of ZQ bioloigcal membrane

Abstract

The present invention discloses the preparation process of ZQ biological membrane with natural structure. The ZQ biological membrane has excellent cell affinity and its decomposition product has no poisoning to cell and degradation rate adaptive to tissue regeneration speed, so that the ZQ biological membrane is an excellent cradlle material. It can be used in planting and bridging of peripheral nerve, repair of ligament, repair of bone and soft tissue holes, etc. and has practical significance in the tissue engineering of peripheral nerve and excellent application foreground.

Description

1. Technical field

[0001] The invention belongs to biomedical soft tissue engineering support materials, and in particular relates to a ZQ biofilm preparation method. 2. Background technology

[0002] At present, PLA, PGA and surface-modified synthetic materials or collagen materials are used as scaffold materials for soft tissue engineering scaffolds to inoculate composite cells for tissue engineering technology, but there are generally poor tissue affinity, and the degradation products are acidic, which is not conducive to the growth and survival of tissue cells. , Collagen degradation too fast and other shortcomings. 3. Contents of the invention

[0003] Aiming at the shortcomings of existing soft tissue engineering scaffold materials such as poor affinity with cells, degradation products that are unfavorable to cell growth, and collagen materials that degrade too quickly and cannot be maintained until the replacement time of regenerated tissue, etc., the present invent...
