Abstract

BACKGROUND: Stem cell therapy in small animal medicine
is still in its infancy and few in vitro and in vivo research projects
regarding animal Mesenchymal Stem Cells (MSCs) have been
carried out. On the other hand, Cell tracking is the first step of the
cell-based therapies and is essential to recognize cell fate post
transplantation. OBJECTIVES: The aim of this study was to
isolate, characterize, and transduce cBM-MSCs. METHODS:
Canine Bone Marrow-derived Mesenchymal Stem Cells (cBMMSCs)
were isolated from bone marrow of dogs and
characterized based on morphology, differentiation capacities,
and surface marker expressions. For the first time, we labeled
cBM-MSCs by GFP-encoding lentiviral vector to track them.
RESULTS: cBM-MSCs were successfully isolated and proliferated.
Morphologically, these cells were similar to other
MSCs from other sources and species and were able to
differentiate into osteocytes and adipocytes. cBM-MSCs
expressed surface marker CD44 but were not able to express
CD34. Approximately, 70% of cells efficaciously expressed
GFPafter labeling; CONCLUSIONS:We found that GFP labeling
is an easy and effective technique to track transplanted cBMMSCs.
Our results also provide fundamental information about
canine BM-MSCs in order to use in veterinary medicine.
