Figure Lengend Snippet: LVs localized subepicardially and perivascularly in left ventricles of hearts from control ( a – h ) and db/db ( i – p ) mice. Most of the lymphatic vessels express all three markers: Lyve-1 (red), Pdpn (white) and CD31 (green) (merge; yellow arrows); few Pdpn-positive cells do not express Lyve-1 or CD31 (merge; white arrows). Merged panels ( d , h , l , p ) include DAPI staining of nuclei (blue). ( m – p ) shows zoomed region of ( i – l ). ( q ) shows relative quantification of mRNA level for Pdpn. ( r ) presents the percentage of Pdpn-positive LVs among all cardiac LVs, as shown in representative confocal microscope images. Scale bars—100 µm. Abbreviations: LV—lymphatic vessel, Pdpn—podoplanin. Statistically significant differences ( p -value < 0.05) are marked (*).
