The aim of the experiment was to investigate the effect of vitrification on viability and the cell cycle of bovine cumulus cells and fibroblasts after culture with or without serum starvation. In all vitrified-thawed bovine somatic cells, the number of samples that reached the confluence stage was high (50 to 100%). The viability of vitrified somatic cells depended on the concentration of the cells. The viability was higher for cells vitrified at the concentration of 10 × 106/ml than for cells vitrified at a concentration of 1 × 106/ml (P<0.05; for cumulus cell, and fibroblast). Time of cell starving has had no impact on their susceptibility to vitrification in case of vitrified cumulus cells. Starving time caused shifts in proportions of subsequent cell cycle phases of vitrified fibroblasts and cumulus cells. In conclusion, the bovine cumulus and fibroblast cells can be cryopreserved successfully by vitrification procedure.

CryoLetters is a bimonthly international journal for low temperature sciences, including cryobiology, cryopreservation or vitrification of cells and tissues, chemical and physical aspects of freezing and drying, and studies involving ecology of cold environments, and cold adaptation
The journal publishes original research reports, authoritative reviews, technical developments and commissioned book reviews of studies of the effects produced by low temperatures on a wide variety of scientific and technical processes, or those involving low temperature techniques in the investigation of physical, chemical, biological and ecological problems.
