ABSTRACT
Microencapsulated recombinant cells technology is a novel approach to tumors therapy. It is necessary to prepare a plenty of the microcapsules with better cell viability and higher endostatin production in order to bring this technology into the clinic. The in vitro culture and cryopreservation are very important parameters in the preparation of microencapsulated cells. In this work, we studied the effect of the in vitro culture and cryopreservation on microencapsulated recombinant cells growth and endostatin production and the effect of the in vitro culture on the cryopreservation of microencapsulated recombinant cells. The results showed that the time of in vitro culture potently affected microencapsulated recombinant CHO cells growth in vivo, endostatin production and the microcapsule stability. The microcapsule kept intact after 36 days of implantation when the in vitro culture time was under 4 days. The thawed microencapsulated recombinant CHO cells had better cell growth and higher endostatin production after 40 days of cryopreservation when the in vitro culture time was 4 days and 8 days. Therefore, the best in vitro culture time was 4 days according to the results of the in vivo culture and cryopreservation and the cryopreservation did not affect microencapsulated recombinant CHO cells growth in vivo, endostatin production and the microcapsule stability.
