The purpose of this work was to isolate and cultivate mesenchymal stem cells (MSC) derived from equine adipose tissue and conduct cellular characterization with the following markers: CD90, CD44 and CD13. Adipose tissue collection was performed at the base of the horses' tails, followed by immediate isolation and cultivation of the MSC and posterior characterization by flow cytometry for the interspecies reaction test using mouse anti-rat CD90 monoclonal antibody (mAb), fluorescein isothiocyanate (FITC), and tests with specific mAb mouse anti-horse CD13 and mouse anti-horse CD44. The technique used for isolation and cell cultivation proved to be safe and viable. The CD90 mAb expressed cross-reaction with MSC derived from equine adipose tissue and CD44 showed greater expression in cells as the number of culture passages increased. Although marker CD13 expresses reaction in other studies involving MSC in different species, it presented no expression in the experiment realized. The results obtained revealed the immunophenotypic characterization of the surface of isolated and cultivated MSC, classifying these cells as a promising type of progenitor cells that can be applied in equine cellular therapy.

D002469 Cell Separation Techniques for separating distinct populations of cells. Cell Isolation,Cell Segregation,Isolation, Cell,Cell Isolations,Cell Segregations,Cell Separations,Isolations, Cell,Segregation, Cell,Segregations, Cell,Separation, Cell,Separations, Cell
D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D000273 Adipose Tissue Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.
