Tri-lineage differentiation of equine BMSCs. Representative microscopic images of Oil Red O, Alizarin Red, and Toluidine Blue staining to confirm adipogenic, osteogenic and chondrogenic differentiation of plastic adherent bone-marrow derived cell populations from four adult equine primary BMSC donors 7–14 days post-induction. Representative non-induced images from donor 1 are included for comparison. All images are obtained with a × 20, 0.7 NA objective
