Isolation and Characterization of an Adult Stem Cell Population from Human Epidural Fat

Figure 4

Collagen contraction assay. Representative images demonstrating contractile activity of HEF cell populations. The area of gel contraction at 24 hr postcell seeding is presented compared to negative (cell-free) control (a). There was no association between cell potency and collagen contraction ability (b). Scale bars represent 1000 μm.
