Figure 4: Changes in Pax7+ve and Pax3+ve cell numbers were also similar between muscle types. The numbers of Pax7+ve and Pax3+ve cells (Red) were counted sequentially (a). The number of Pax7+ve cell in the tibialis anterior muscles was markedly lower the number of Pax3+ve cell (b). The number of Pax3+ve cell in the tibialis anterior muscles increased from the 1st week and declined (c). In the soleus muscles, both Pax7+ve and Pax3+ve cell number increased from the 1st week, but declined from the 2nd week (d and e). The changes in the cell numbers were consistent with the results of quantitative polymerase chain reaction (f).
