Abstract (original English)

Cell-based therapies, such as the use of mesenchymal stromal cells (MSCs), are becoming popular in veterinary medicine. When MSCs are not cryopreserved, they are shipped in suspension, but no previous studies have analyzed MSC viability during delivery. Here, the impact of several experimental shipping conditions on the number of equine blood-derived (ePB-MSC) and canine adipose-derived (cA-MSC) MSCs were evaluated. Among the different parameters tested, only time and temperature influenced MSC number during the experimental shipping conditions. Cells were monitored over different time intervals for gene expression of typical MSC markers and to evaluate acquired resistance to apoptosis and beta-galactosidase activity. Overall, these results indicate that ePB-MSC and cA-MSC should be delivered in phosphate buffered saline at room temperature and within 9-12 h.
