Abstract: | Adipose tissue-derived stem cells (ADSCs) represent a promising subpopulation of adult stem cells for tissue engineering applications
in veterinary medicine. In this study we focused on the morphological and molecular biological properties of the ADSCs. The
expression of stem cell markers Oct4, Nanog and the surface markers CD90 and CD105 were detected using RT-PCR. ADSCs showed
a proliferative potential and were capable of adipogenic and osteogenic differentiation. Expression of Alkaline phosphatase
(AP), phosphoprotein (SPP1), Runx2 and osteocalcin (OC) mRNA were positive in osteogenic lineages and peroxisome proliferator
activated receptor (Pparγ2) mRNA was positive in adipogenic lineages. ADSCs show stem cell and surface marker profiles and
differentiation characteristics that are similar to but distinct from other adult stem cells, such as bone marrow-derived
mesenchymal stem cells (BM-MSCs). The availability of an easily accessible and reproducible cell source may greatly facilitate
the development of stem cell based tissue engineering and therapies for regenerative equine medicine. |
