Figure 2 Morphological comparison of primary cells. A: Conventional adherence (group A): 48 hours, cells migrated out (a1); 7 days, island-like colonies with contaminants (a2); 10 days, target cells and contaminants coexisted (a3); B: Density gradient centrifugation (group B): 48 hours, rapid adhesion (b1); 7 days, homogeneous colonies (b2); 10 days, uniform fibroblast-like morphology (b3). Scale bars: 500 μm (a1, a2, b1, b2) and 200 μm (a3, b3).
