Figure Lengend Snippet: (A) Cartilage degeneration scores and representative histological images of knee sections from WT mice injected with vehicle, low NGF or high NGF, respectively; (B) Small chondrophytes or pre-osteophytes developed on the medial side. The graph shows the width in µm with representative histological images of wild-type (WT) mice injected with vehicle (5 µL, 2x/week), low NGF (50 ng, 5 µL, 2x/week), or high NGF (500 ng, 5 µL, 2x/week) for 4 weeks, n=5 mice/group. Black insets in B showing examples of developing pre-osteophytes in low dose and high dose NGF groups; (C-F) Bone volume / Trabecular volume (BV/TV) ratio, bone mineral density (BMD, in mm), mean trabecular thickness (Tb.Th, in mm), mean trabecular separation (Tb.Sp, in mm) respectively in the medial and lateral tibial subchondral trabecular bone from knees injected with NGF (500ng, n=6) or Vehicle (n=4); (G) Representative µCT scans of the subchondral trabecular bone from vehicle and NGF groups, respectively. For A and B, we used two-way ANOVA with Sidak’s post-test. For C-F, we used unpaired two-tailed t test. Scale bar=100µm.
Article Snippet: In Experiment 1, NGF (R&D systems, # 1156-NG-100), 50ng or 500ng in 5 μL, or vehicle control (0.1% BSA) (05470, Sigma) (n=5 mice/group) were injected IA into the right knee joint of naive 12-week-old male WT mice, twice a week for 4 weeks.
Techniques: Injection, Two Tailed Test
