The formation of somatic cell banks is affected by, amongst other factors, the cryoprotectant solution used. The selection of an effective solution, therefore, is a primary parameter.We optimized the cryoprotectant used for collared peccary somatic cell cryopreservation.We categorized cells into different groups based on their cryopreservation and evaluated the morphology, viability, proliferative activity, metabolism, and oxidative stress. One group was cryopreserved in 10% DMSO with 10% fetal bovine serum (DMSO-10FBS), and another with 50% FBS (DMSO-50FBS). The cryopreservation of both groups included the presence of 0.2 M sucrose (DMSO-SUC-10FBS and DMSO-SUC-50FBS). Non-cryopreserved cells and cells cryopreserved with 10% DMSO (DMSO) supplemented with 0.2 M sucrose (DMSO-SUC) were used as controls.There was no difference observed in morphology or viability among the groups. Proliferative activity was reduced in DMSO-10FBS when compared to controls. Although cryopreservation reduced metabolism, no difference was observed among solutions. A lower level of reactive oxygen species was observed in cells of DMSO-SUC-50FBS when compared to other cryoprotectants. Only cells of DMSO-SUC-50FBS had mitochondrial potential similar to non-cryopreserved cells.10% DMSO supplemented with 50% FBS and 0.2 M SUC was observed to be the most efficient cryoprotectant for preserving collared peccary somatic cells. |
