Dynamics of Acute Local Inflammatory Response after Autologous Transplantation of Muscle-Derived Cells into the Skeletal Muscle
Figure 6
The skeletal muscle stained with hematoxylin and eosin. Images present the area of injection at days 1, 3, and 7 after procedure in subsequent rows. (a and b) Cross sections from transplanted group in two different magnifications. Distinct clusters of injected cells are visible. Dashed lines drawn on images in column A indicate approximate area of clusters located between muscle fibers. At day 1, neutrophils can be recognized within the cluster (arrows). At day 3, identification of neutrophils is not obvious; large mononuclear cells dominate in the cluster. At day 7, inflammatory infiltration is not clearly visible anymore; (c and d) cross sections from group injected with vehicle only in two different magnifications. Some inflammatory cells could be recognized in samples collected at day 1 time point.
