[Quantitative assessment of fibroblast viability in cryopreserved aortic valve allografts].

The purpose of this study is to clarify whether serum (fetal bovine serum or human serum) is necessary or not for cryopreservation of aortic valve allografts. The protective effects of fetal bovine serum compared with human serum were evaluated by means of quantitative assessment of fibroblast viability. Porcine aortic valves were excised and rinsed… CONTINUE READING
