Figure 3From: 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 rabbitInjections of cell tracer in IVDs and KJs into niche regions. X-ray images showing injections of cell tracers (iron nanoparticles or CDFA-SE) in (A) the IVD niche region and (B) the niche region of KJs located adjacent to the epiphyseal plates (EPs). A 20-gauge needle was used for the injections of cell tracers.Back to article page
