Researches on Stem and Progenitor Cells in Intervertebral Discs: An Analysis of the Scientific Landscape

Figure 7

Keywords clusters on stem and progenitor cells in intervertebral discs. (A point in the figure represents a keyword. The color of the point represents different clusters, and the size of the point represents the co-occurrence for each keyword. The more the co-occurrence, the larger the point; # represents different cluster labels, #0 human intervertebral disc, #1 adipose-derived mesenchymal stem cell, #2 intervertebral disc degeneration, #3 degenerative disc model, #4 nucleus pulposus regeneration, #5 human cartilage, #6 3d culture, #7 shrinkage-free preparation, and #8 polylactide disc.)
