Isolation, Characterization, and Multipotent Differentiation of Mesenchymal Stem Cells Derived from Meniscal Debris

Figure 1

Magnetic resonance imaging (a) showing a typical bucket-handle tear of medial meniscus in sagittal view and arthroscopic examination (b) of patients with meniscal tears. Meniscal debris (c) was obtained during surgery. At 35 d after plating, some cells were observed to adhere to the culture dish (d). Cells took on a swirling or cluster appearance by 10–12 d (e), and they remained homogeneous until the third passage (f). Scale bar = 100 μm.
