FIGURE 5.
Matrigel embedded capillary sprouting capacity and Griffonia Simplicifolia Lectin-IB4 IF-staining of isolated MRPECs 10 days post-isolation. Representative phase-contrast photomicrographs and IF-images of MRPECs embedded in a Matrigel assays 36 h after Griffonia Simplicifolia Lectin-IB4 (GSL-1) staining and implantation. (A) Nuclear staining, DAPI (blue), (B) GSL-I staining (green), (C) phase-contrasted photomicrograph of embedded MRPECs (gray), and (D) overlay (merged); white arrows indicate capillary spouts/tubes. All representative images were taken at 20× magnification. All images were obtained on an EVOS-M5000 fluorescence microscope system and merged by overlay in FIJI (ImageJ) software. N = 4 isolations. Scale bars, 50 μm.
