Percentage summary of interzone formation and cartilage fusion. All the samples analyzed for in situ hybridization were individually scored for the presence and absence of the interzone and cartilage fusion. A) The percentage of samples that display interzone formation after window excision (WE) and slice excision (SE) at 60h and 72h after surgery. At both time points, a significantly higher number of samples after WE have interzone formation, 88% at 60h and 67% at 72h. In contrast, only 12.5% of samples have interzone formation at 60h and none of them display a joint interzone at 72h. Interzone formation indicates joint regeneration. B) A significantly higher percentage of samples after SE surgery display fusion of the humerus and the ulna at 60h (75%) and 72h (100%), in contrast to WE samples which do not show fusion at 60h or a much lower percentage of samples at 72h (22%). Skeletal fusion indicates failure of regeneration.
