Following the peritendon was removed by means of microsurgical technique, the tenocyte was isolated from the human embryonic tendons by digesting it with trypsin and collagenase. These cells were all stored in frozen condition until they were cultured by F12 culture fluid added with 20% FBS to the 15th generation.These cells were able to grow adhering to the wall and stop growing with contact inhibition. The time of cellsgroup duplication was 4 days, which was similar to the peak time of its mitosis. The number of its chromosome group 2n=46 was 87.5-91.0%. The optimal conditions for tendon cell culture in vitro were investigated, and it was found that after they were reaminated and subcultured the frozen storage didn’t influence their growth, morphology, genetic characteristics. In our research we detected the content generation cells and found the cultured human embryonic tenocyte had same ability never changed with the cells subcultured. We also disscussed the future of tenocyte-a biomaterial in the field of artificial implant.
