Abstract (original English)

Mesenchymal Stromal Cells (MSCs)-based therapies are rapidly gaining interest in veterinary medicine. Cellular therapy represents a new challenge for practitioners and requires precise coordination between the cell processing laboratory and the veterinary clinic. Cryopreservation is the best method to provide fast, in-time, and long-distance delivery of cells for therapeutic applications. However, potentially toxic cryoprotectants and xenobiotic products make the direct administration of cells impracticable for patients. Alternatively, the cells may be resuspended in a ready-to-use vehicle and shipped to the veterinary clinic. In this study, two nutrient-poor vehicles (physiologic saline and ringer lactate solutions) and two nutrient-rich vehicles (the releasate derived from autologous Platelet Poor Plasma and Platelet Rich Plasma) were tested on adipose tissue-derived canine MSCs (AD-MSCs). AD-MSCs stored for 2, 4, or 24 h in the different media were compared regarding mortality, metabolic activity, and replicative capacity. Furthermore, antioxidant activity and the pattern of expression of genes related to AD-MSCs function were performed following 24 h of storage. The results showed that all the different vehicles preserve cell vitality and replication following short-term storage. In long-term storage, the vehicle and cell density affect cell vitality, proliferation, and gen
