LB in skeletal muscle.

<p>(a) Muscle from a LKO mouse stained with PAS-D. Note presence of numerous LB in many fibers; bar, 100 µm; arrows, LB-replete myofibers; arrowheads, myofibers not containing LB. (b) Comparable field from a DKO mouse; bar, 50 µm. Higher magnification chosen for the DKO example to illustrate lack of even small LB.
