Fig. 1From: Zonal characterization and differential trilineage potentials of equine intrasynovial deep digital flexor tendon-derived cellsEquine intrasynovial TDC in vitro morphology and CFU. a Morphology of TDC during monolayer passage. At passage 0 (P0), attached cells from the fibrocartilaginous and tendinous zones were polygonal and elongate/spindle-shaped cells, respectively. At passage 3 (P3), both fTDC and tTDC were homogenous and exhibited fibroblast-like morphology. Scale bar = 100 microns. b Colony forming unit assay of cells from the fibrocartilaginous and tendinous zones after 10 days of culture. Scale bar = 1 cm. Bars represent mean ± SD CFUBack to article page
