Repair of Osteochondral Defects Using Human Umbilical Cord Wharton’s Jelly-Derived Mesenchymal Stem Cells in a Rabbit Model

Figure 2

Human umbilical cord Wharton’s jelly mesenchymal stem cells (hWJMSCs) cultured on cartilage extracellular matrix-derived scaffolds. Most cells were alive when stained with fluorescein diacetate (FDA) (a) and propidium iodide (PI) (b), (c) merge, (d) quantification of the live and dead cells in the confocal image. Scanning electron microscopic (SEM) examination revealed that cells grew well on the scaffolds after 14 days of culture ((e) and (f)).
