Isolation and Characterization of Human Synovial Fluid-Derived Mesenchymal Stromal Cells from Popliteal Cyst

Figure 2

Morphological characteristics of SF-MSCs. P0: representative characteristics of SF-MSCs at primary passage within 48 h—the cell exhibiting individual colony adhered to the culture plates and nonadherent or few adherent small round cells are scattered in the culture plates (100x). P1-P4: representative characteristics of SF-MSCs from passage 1 to passage 3, between day 3 and day 10—cells exhibit the fibroblastic spindle-like shape (100x). P5-P8: representative characteristics of SF-MSCs from passage 4 to passage 8—the cells show fibrocyte-like form with long fusiform shape, grow in the same direction, and maintain the morphology (100x).
