Fig 3. Decellularization efficiencies of study 1 and study 2 treatments.

(A) Cell densities (mean±SD; averaged over sample) were calculated for each treated group and compared with control and group 5, which showed the lowest cell density after treatment (*compared with control *** p<0.001; ^#compared with group 5, ^## p<0.01, ^### p<0.001,). (B) Decellularization efficiency was defined as the ratio of removed cells and compared with group 5 (** p<0.01, *** p<0.001). (C, D, E) Cells were efficiently removed from all three regions of the sample in group 5, 6, and 10. Scale bar = 100 μm. T, I, B refer to tendon, interface region, and bone, respectively.
