A: postnodal lymphatic vessel sections stained with Masson's Trichrome and hematoxylin and eosin (H&E) to estimate the percent area of the constituents of interest: vessel total area (TA), medial area (MA), area occupied by collagen (TCA), and smooth muscle cells (SMCA). B: between the Sham (n = 8) and MVH (n = 8) groups, there were no significant differences in the smooth muscle cell area/total area ratio (SMCA/TA), total collagen area/total area ratio (TCA/TA), medial collagen area/total area ratio (MCA/TA), smooth muscle cell area/medial area ratio (SMCA/MA), and medial collagen area/medial area ratio (MC/MA). C: Ratio of total cross-sectional area for SMC/TA, TCA/TA, and MCA/TA. Data are presented as means ± SE.
