Abstract

|

Background: Mesenchymal stem cells (MSCs) from different sources have different characteristics. Moreover, MSCs are not isolated and characterized in Guinea pig for animal model of cell therapy.
Aim of the Work: was the isolating of bone marrow MSCs (BM-MSCs) and adipose tissue MSCs (AT-MSCs) from Guinea pig and assessing their characteristics.
Material and Methods: In this study, bone marrow and adipose tissue were collected from three Guinea pigs and cultured and expanded through eight passages. BM-MSCs and AT-MSCs at passages 2, 5 and 8 were seeded in 24-well plates in triplicate. Cells were counted from each well 1~7 days after seeding to determine population doubling time (PDT) and cell growth curves. Cells of passage 3 were cultured in osteogenic and adipogenic differentiation media.
Results: BM-MSCs and AT-MSCs attached to the culture flask and displayed spindle-shaped morphology. Proliferation rate of AT-MSCs in the analyzed passages was more than BM-MSCs. The increase in the PDT of MSCs occurs with the increase in the number of passages. Moreover, after culture of BM-MSCs and AT-MSCs in differentiation media, the cells differentiated toward osteoblasts and adipocytes as verified by Alizarin Red staining and Oil Red O staining, respectively.
Conclusion: BM-MSCs and AT-MSCs of Guinea pig could be valuable source of multipotent stem cells for use in experimental and preclinical studies in animal models.
