Embodiment 1
[0062] The invention discloses a method for constructing a pig-derived collagen membrane-autologous chondrocyte composite scaffold, and the specific steps are as follows:
[0063] (1) Take about 300 mg of articular cartilage in the non-weight-bearing area of the patient, remove the clean soft tissue, put the remaining transparent cartilage tissue pieces into a centrifuge tube filled with PBS buffer, shake and wash until the residual blood is rinsed away;
[0064] (2) In a sterile plate, cut the cartilage tissue into pieces of 1 mm with ophthalmic scissors 3 fragments of
[0065] (3) Digest the above fragments with 0.25% (m / v) trypsin for 30 minutes, and discard the supernatant;
[0066] (4) Digest the fragments with 5ml of 0.02% (m / v) type II collagenase at 37°C in a 5% CO2 incubator for 8 hours, shake once every 1 hour until they become flocculent, and obtain cell suspensions. liquid;
[0067] (5) Filter the cell suspension with a 100um filter, add FBS-containing high-su...
