Figure 2. IKK2 muscle depletion increases number of intermediate fibers.

(A and B) Increased number of intermediate fibers in Ikk2^mko soleus with similar number of slow fibers. (C) Mean percentage increase in Ikk2^mko soleus total CSA. (D–F) The number of intermediate fibers in the Ikk2^mko EDL was modestly but not significantly increased while the number of other fiber types remained unaltered. (G) Mean percentage of total CSA of the EDL was similar between control and Ikk2^mko animals. **Mean values differ significantly from those of control (P < 0.002).
