Figure 4. 6mer and 40 kDa HA moderately increase macrophage infiltration during wound repair.

A: Cross sections of 7 days old wounds were stained with INOS specific antibodies as described in Materials and Methods. Positive cells were counted/area granulation tissue. Graph shows Mean±SE of N = 18 (6 sections, three areas/section). B: Cross sections of 7 days old wounds were stained with ARG1 specific antibodies as described in Materials and Methods. Positive cells were counted/area granulation tissue. Graph shows Mean±SE of N = 18 (6 sections, three areas/section).
