Parameters for post-operative tail volumes were shown by the calculations as previously reported (by using the parameters (C1, C2,…., C8) in Fig. 1A) [14]. Figure 1B shows the sequential observation of the swelling status of TEST-operated mouse tail with the illustration for the volume calculations. POD0 (post-operated day 0) and the gradual increase (POD0–21) and plateau (POD21–35) points of the operated tails were shown (Fig. 1B)
