Figure 2. Swim-training accelerated both chondrogenesis and osteogenesis.

A) CF50_age values of trained fish plotted against CF50_age values of control fish with a linear regression fit (solid line). Dashed line is a reference line which indicates the CF50_age values which are not different between control and trained fish. Plus signs indicate cartilage structures without BF50_age values, squares are with BF50_age values. B) Similar plot as in A but with CF50_lgt values. C) Duration of cartilage phase for cartilage bones (in days, indicated with squares in A and E) plotted against the CF50_age values of control and trained fish with a linear regression fit (solid lines) (trained fish: black dots and black regression line, control fish: grey dots with grey regression line). D) Similar plot as in C but with duration of cartilage phase (days) plotted against the CF50_lgt values of control and trained fish. E) Similar plot as in A but with BF50_age values. Red dots indicates BF50_age values of dermal bones, plus signs of cartilage bones without CF50_age values, squares of cartilage bones with CF50_age values. Dashed line see A. F) Similar plot as in E but with BF50_lgt values.
