Comparison of Three Different Methods for Cryopreservation of Fibroblast and Study on Factors Which Influence Cell Viability |
|
() |
Abstract: |
Fibroblast is a crucial kind of cell in the construction of tissue engineered dermal equivalent. The cryopreservation of fibroblast has great significance to the tissue-engineered dermis. The pretreatment processes and three different cryopreservation methods of fibroblast were studied in this study. And the cell viability, the temperature history, and instruments required of these three methods were compared. In addition, the influences of DMSO concentration, and pretreatment time, and temperature on cell viability were also invesgated. |
