Equine mesenchymal stem cells from bone marrow, adipose tissue and umbilical cord: immunophenotypic characterization and differentiation potential

Mesenchymal stem cells (MSC) represent a heterogeneous population with the capacity to self-renew and differentiate into different cell types. At the middle of the last century these cells initially were described in bone marrow (BM), thence this tissue has become the gold standard for obtaining and characterization of MSC. It is known that these cells are housed in specific areas called niches distributed throughout all body, where they contribute to tissue regeneration processes of self-tissue were they are located. However, finding an alternative source of CTM with the same characteristics that have showed in MO, but its obtention no represent a risk since the donor is essential to their use for therapeutic purposes. In this study we isolated mesenchymal stem cells from bone marrow, adipose tissue and Wharton’s jelly and they were compared in their characteristics in according to the standards of the International Society for Cellular Therapy (ISCT). The results showed that the morphology as well as adipogenic and osteogenic differentiation and also the expression of surface antigens (CD90, CD73, and CD105) from all tissues accomplished the standards, although Wharton’s jelly represented the best option.

Mesenchymal stem cells (MSC) can be applied for treatment of different diseases. Human MSC have been isolated from bone marrow, adipose tissue, umbilical cord blood. umbilical cord MSCs (uC- MSC) are obtained during birth with non-invasive, non-traumatic methods and thus seem a good candidate for clinical practice instead of bone-marrow MSC (BM-MSC). It is yet unknown wheth- er the immunophenotype and proliferation capacity of uC-MSC are similar to adipose-derived stem cells (AdSCs) or BM-MSC. The goal of this research was to study the immunophenotype and prolifer- atiion capacity of uC-MSC, AdSCs and BM-MSC. The results indicated that MSC of different origin had similar morphological and immunophenotypic characteristics with minor differences. uC-MSC differed from other cultures by constant level of Cd105 expression, the presence of minor Cd10 - and Cd13 - populations and higher proliferative activity. BM-MSC were characterized by reduced expres- sion levels of Cd90, compared with the uC-MSCs and AdSCs. These data confirm the similarity of uC-MSC with BM-MSCs and AdSCs and the possibility of their use in clinical practice instead of hard-to-obtain BM-MSC.
