Fig. 3

Ex vivo RSOM images of healthy compared to KO mice. A, B Exemplary MIP images of female (A) and male (B) kidneys are shown. Top row WT genotype, bottom row KO genotype. Merged frequencies (big and small vessels, red-green), low frequencies (bigger vessels = red), and higher frequencies (smaller vessels = green) are shown. Scale Bars 1mm. C, D WT and KO female (C) and male (D) kidneys were compared for absolute kidney area in mm2, relative vessel area, and absolute vessel area in mm2 derived from merged images. Bars and whiskers mark mean±SD. A p value <0.05 indicates statistical significance. ns=not significant, MIP=maximum intensity projection. LF=low frequencies, HF=high frequencies, MF=merged frequencies, WT=wildtype genotype, KO=knock-out genotype, min.=minimum, max.=maximum
