    Abstract:
    Amniotic fluid (AF) represents heterologous cell types and a specific group of these cells show high growth rate and multipotent characteristics. The aim of the present study was to culture and fully characterize the putative stem cell population isolated from caprine mesenchymal stem cells. Plastic adherent fibroblastoid cell population could be successfully isolated from the caprine amniotic fluid. In vitro expanded caprine amniotic fluid derived mesenchymal stem cells (cAF-MSCs) showed high proliferation ratio with a doubling time of 33.1h and stained positive for alkaline phosphatase. Relative transcript abundance of CD-73, CD-90 and CD-105 surface markers were analyzed by SYBR green based real time PCR and their respective proteins were localized through immunocytochemistry, however cAF-MSCs were found negative for haematopoietic marker CD-34. When exposed to corresponding induction condition, cAF-MSCs differentiated into osteogenic, adipogenic and chondrogenic lineages which was confirmed through von Kossa, Oil Red O and Alcian blue staining respectively. Furthermore, these cells were found positive for undifferentiated embryonic stem cell markers like Oct-4, Nanog, Sox-2, SSEA-1 and SSEA-4 which accentuate their pluripotent property. In conclusion, caprine amniotic fluid represents a promising source of mesenchymal stem cells with high proliferative and differentiation potential and these cells offer their scope for multiple regenerative therapies.
