Effect of Static Load on the Nucleus Pulposus of Rabbit Intervertebral Disc Motion Segment in an Organ Culture

Table 2

Collagen type II IHC staining intensity of the NP during organ culture.

Culture time point	Day 0	Day 3	Day 7	Day 14
Static load		61.54 ± 5.91	22.97 ± 5.03	30.43 ± 2.13

The values represent the means ± SD. Significance of differences between culture time point and fresh tissue (day 0); significance of differences between culture time point and day 3. IHC: immunohistochemistry; NP: nucleus pulposus; SD: standard deviation.
