Figure Lengend Snippet: (A) Schematic illustrating site of tissue collection from below- and above knee amputations. (B) Myography showing increased endothelial dysfunction in female vs male patient arteries. Left , endothelial-dependent relaxation in response to acetylcholine (ACh). Right , No difference in vascular smooth muscle cell (VSMC), sodium nitroprusside (SNP)- mediated relaxation (n=3-5). (C) Left, representative image of microvessels in tibialis anterior (CD31 + SMA + , yellow arrows). Laminin (myocytes, white), CD31 (ECs, red) and SMA (pericytes, green); scale bar 50 μm. Right , quantification (n=5/sex). (D) Myocyte area is unaltered with sex (n=5). (E) NADPH oxidase ( Nox ) mRNA marker expression in muscle measured by qPCR, normalized to β -actin (n=5). (F) 8-isoprostane levels in plasma remain unchanged with sex (n=5). Results are mean±SEM; two-way ANOVA, Student’s t -test or Mann–Whitney U -test; * P <0.05, ** P <0.01, *** P <0.001.

Figure Lengend Snippet: (A) Schematic to show vessel collection for myography. (B) Myography showing increased endothelial dysfunction in female vs male arteries. Left , endothelial-dependent relaxation in response to acetylcholine (ACh). Right , sodium nitroprusside (SNP)-mediated relaxation (n=5-7). (C) Myography in non-injured vessels (N=5-7). (D) Plasma nitrite/nitrate levels (n=4-6). Laser Doppler imaging showing reduced blood perfusion over time with diabetes in (E) male and (F) female mice. Left, representative image of blood flow at 14 d. Right, quantification. (n=9-11). (G) Laser doppler perfusion index at 14 days (n=9-11). (H) Microvessel number (CD31+SMA+, <50 µm in diameter) in gastrocnemius tissues normalized to the number of myocytes and control non-ischemic limbs (n=9-11). (I) Tubule formation of male and female murine ECs shows an altered phenotype. (J) Tubulogenesis is reduced in female ECs under diabetic conditions. Left, Wimasis platform for vessel coverage and networks. Right , quantification (n=5/group). Results are mean±SEM; two-way ANOVA, Student’s t -test or Mann–Whitney U -test; * P <0.05, ** P <0.01, *** P <0.001 and **** P <0.0001.
