ABSTRACT Adult stem cells derived from all possible sources of livestock serve as the best possible alternative to embryonic stem cells. The discovery of mesenchymal stem cells has provided the new horizon to stem cell therapy. Adipose tissue derived mesenchymal stem cell (ADSCs), an easy source of adult stem cell has created a lot of interest among researchers as patient specific treatment and autologous transplantation in animals is becoming a viable option. The proposed study was carried out for 1) isolation of ADSCs from dogs, suffering from hip dysplasia or from paraplegia, 2) ADSC characterisation and in vitro differentiation ability into osteocytes, chondrocytes, adipocytes and neurocytes specific cells. Adipose tissues were collected from belly/umbilical cord region. ADSCs were isolated by enzymatic digestion method followed by enriching through a 41μm filter. Filtered cells were then resuspended in cell culture flasks containing growth enriching medium and cultured in 5% CO2 in air at 37°C for 5 days. ADSCs were characterised by amplification of mesenchymal stem cell specific markers i.e. CD29, CD44, CD90, and CD166 and by immunocytochemistry of mesenchymal stem cell specific protein i.e. CD44 and CD90. ADSCs were further in vitro differentiated. ADSCs derived osteocytes, chondrocytes, and adipocytes were validated through the amplification of specific markers of osteocytes (Osteopontin, Collagen I); chondrocytes (Aggrecan and Collagen II) and adipocytes (LPL, PPARα, PPARγ). Dog ADSCs were further autogenic transplanted into hip dysplasia and paraplegic patients. These patients recovered well one month from transplantation and were able to move freely. It may be concluded that these findings may have implications for defining the physiological roles of ADSCs in arthritis; orthopaedic ailments, joint regeneration, neuronal disorders, and several other applications leading to novel therapeutic opportunities.
