Abstract

Tissue engineering (TE) is a new discipline that offers the potential to create replacement structures from autologous cells and biodegradable polymer scaffold. Various vascular and valvular grafts have been tried to create with this TE approach. In clinical use of this technique, harvested and cultured cells have to keep viability until implantation as tissue engineered tissue. But few research for cryopreservation of vascular mixed cells has been performed. So, we investigated the proper method for cryopreservation of vascular mixed cells harvested from femoral artery and vein of dogs. Cells were cultured and divide into three groups, A: cryopreserving in 5% dimethylsulfoxide (DMSO), hydroxyethyl starch (HES), and fetal bovine serum (FBS) with -80 degrees C freezer; B: cryopreserving in 10% DMSO and FBS with programmed freezer; C: control (continuous culture in media). After rapid thawing at 40 degrees C, group A showed higher viability than group B with flow cytometry. The results means that vascular mixed cells can be successfully cryopreserved in the DMSO/HES mixture simply and inexpensively, without rate controlled freezing.
