Figure 4From: Similar cellular migration patterns from niches in intervertebral disc and in knee-joint regions detected by in situ labeling: an experimental study in the New Zealand white rabbitViability tests. Upper row: 64.4% small cells (cell diameter <10 μm) and 23.7% large cells (cell diameter >10 μm) of the total IVD (AF and NP) cell population were sorted by size by using the forward-scatter parameter, and gating parameters are indicated by squares. Outcome of the test of viability was 96.5% viable and 3.5% nonviable cells. Lower row: 3. 8% GDF5+ cells were sorted from the total cell population by using an antibody directed toward GDF5.Back to article page
