From: The efficacy of Link N as a mediator of repair in a rabbit model of intervertebral disc degeneration
Histologic changes after injection of saline or Link N. Safranin O-stained sections of control (nonpunctured), saline-treated, and Link N-treated discs comparing the degree of degeneration. In comparison with the saline-treated group, the Link N group displayed a restoration of the nucleus pulposus (NP) with the presence of intensely stained matrix and large cells typical of a control nucleus pulposus. AF, annulus fibrosus; GP, growth plate.
