Intervertebral Disc-Derived Stem/Progenitor Cells as a Promising Cell Source for Intervertebral Disc Regeneration

Figure 1

Schematic overview of the location of different kinds of IVDSCs. The stem cells located in IVD and the adjacent vertebras are indicated with dots. Elliptical broken line indicates the area of stem cell niche. The arrows indicate the possible migration pathways of SCNSCs. BMSC: bone marrow-derived stem cells; SCNSC: stem cell niche-derived stem cells; CESC: cartilage end plate-derived stem cells; NPSC: nucleus pulposus-derived stem cells; AFSC: annulus fibrosus-derived stem cells; CEPC: cartilage end plate cells. AFC: annulus fibrosus cells.
