Article Title: High-throughput differentiation of human blood vessel organoids reveals overlapping and distinct functions of the cerebral cavernous malformation proteins

doi: 10.1007/s10456-025-09985-5

Figure Lengend Snippet: High-throughput (HT)-compatible and nearly xeno-free synthesis of vascular networks and blood vessel organoids from fluorescently tagged human induced pluripotent stem cells (hiPSCs). A Schematic illustration of the new differentiation protocol and representative images for the main differentiation steps (scale bars: d-2, d0, d3, d5 = 100 µm; d7, d12 = 250 µm; d14, d17 = 500 µm). Created in BioRender. Skowronek, D. (2025) https://BioRender.com/e70e302 . B Shown are the steps of embedding the vascular aggregates in an Akura 96-well plate and transferring the vascular networks from the Akura 96-well plate to a PrimeSurface 96 Slit-well plate. C The use of PrimeSurface 96 Slit-well plates reduces the time required for medium exchange (left image). Akura 96-well plates allow aggregates to be embedded in small cavities, minimizing the matrix surrounding the vascular networks (black arrows) and allowing direct transfer of vascular networks (white arrows) to new plates without time-consuming manual extraction of the networks from the gel (middle and right images). D The new protocol is simple to handle and achieves high synthesis efficiency after minimal training. Shown are the efficiencies of three training runs. E The sprouting efficiency is maintained when fetal bovine serum (FBS) is replaced with human platelet lysate (hPL) or chemically defined Panexin CD (PCD). The total numbers of sufficiently sprouted networks and vascular aggregates with insufficient sprouting are written inside the bars. F,G HiPSC-derived vascular networks (F) and blood vessel organoids (G) differentiated with the HT-compatible and nearly xeno-free protocol consist of a complex network of endothelial cells (CD31) and associated pericytes (PDGFR-β) [representative images; scale bars: 50 µm ( F ); 200 µm ( G )]. White arrowheads indicate angiogenic sprouts. H Perfusion of vascular networks with TMR-amino-dextran in OrganoPlate graft plates shows anastomoses between the GFP-labeled vascular networks and the HUVEC-derived vascular bed (top, white arrowheads) as well as correct formation and permeability of the vascular networks (bottom, scale bar: 50 µm)

(2025) https://BioRender.com/n06n764 . B Shown are blood vessel organoids cultivated on the CAM associated with chicken blood vessels. The pictures were taken on day 1 and day 6 (scale bars = 2 mm). C Sectioning and H&E staining demonstrated nucleated chicken erythrocytes within the vascular structures of the blood vessel organoid (black arrow head) (upper scale bar = 500 µm; bottom scale bar = 25 µm). D The expression of CD31 (upper image) and PDGFR-β (lower image) were verified by immunohistochemistry staining (brown) (scale bar = 100 µm)

Figure Lengend Snippet: Structural defects in KO vascular networks. A Immunofluorescence staining for CD31 (endothelial marker, green) and PDGFR-β (pericyte marker, red) indicated a reduced correlation between ECs and pericytes in CCM1, CCM2, and CCM3 KO vascular networks (scale bar: 100 µm). Correlation was evaluated by using the Pearson’s correlation coefficient (r) calculated with the JACoP ImageJ plugin. B , C Immunofluorescence staining for ZO-1 (B) and VE-cadherin ( C ) revealed irregular tight and adherens junctions in CCM1 , CCM2, and CCM3 KO vascular networks (Alexa 647; scale bars: 25 µm). Statistical analyses demonstrated a significant reduction of Alexa 647 (ZO-1) fluorescence intensity in CCM2 and CCM3 KO networks. Data are presented as individual data points and means. Multiple two-sample t-tests with Welch's correction and Holm-Šídák adjustment for multiple testing were used for statistical analyses (* = Padj < 0.05)
