Abstract:
[Objective]To study the effects of different storage method on the viability of cheodroeytes so as to find out the idem method for preservation of articular cartilage.[Method]Under the aseptic condition,acquiring 240 pieces of osteoehondral plugs from both condyles of femur and tibial plateau.The control group was not treatment using any preserved means.The tissue-cultured group was to used F12-DMEM medium long-term preserved osteochondral plugs under the conditions of 37 ℃.At preserve 8 weeks,takes the osteochondral section to carry on examination observation ohondrocytes Viability activeness change separately.[Result]The control group chnadrocyte survival rate was 94.4%.At preserves 8 weeks,the cell survival rate of the tissue-cultured group was 76%,the grading-cooling cryopreservation group was 66%,the constant-cooling cryopreservation group only was 41.80%.[Conclusion]Under the condition of 37 ℃,tissue culture method can long term preservation of vital articular cartilage in vitro.The chondrocyte survival rate of the preservation of vital articular cartilage in vitro.The chondrocyte survival rate of the tissue-cultured method obvious higher than constant-cooling cryopreservation method.
