Figure 4. Quantification of BrdU labeling and histomorphometry of the proliferating zone. (A) The average BrdU labeling index of the proliferating zone treated with cyclic force (N = 7) was significantly greater than that of static force (N = 6) (p < 0.05) and sham control (N = 7) (p < 0.01). (B) The average total area of the proliferating zone treated with cyclic force was significantly greater than those of static force (p < 0.05) and sham control (p < 0.01).
