Figure Lengend Snippet: a, Schematic of microwell plates in 96-well plate format and representative phase contrast image of a GRi3D organoid array within a single well. Scale bar, 1 mm. b, Quantification of blood-brain barrier organoid diameter in GRi3D microwell arrays within 24- or 96-well plate compared to organoids grown on agarose substrate. Each dot represents a single organoid, while different colors represent independent experiments. c, Representative confocal images of a blood-brain barrier organoid labelled with cell type-specific markers showing specific layering and organization of brain endothelial cells (P-gp, magenta), pericytes (NG2, green) and astrocytes (GFAP, cyan) when grown in GRi3D arrays. Nuclei are labelled with DAPI (grey). Scale bars, 100 μm. d, Representative fluorescent image of a live/dead staining showing the viability of blood-brain barrier organoids grown on GRi3D arrays. Calcein AM in green labels live cells whereas ethidium homodimer-1 in magenta labels dead cells. Scale bar, 1 mm. Images on the right show a higher magnification of the boxed area. Scale bar 500 μm.
Article Snippet: Human brain microvascular pericytes (HBVP, ScienCell Research Laboratories) were cultured in Pericyte Growth Medium (PGM) composed of Pericytes Medium (PM, ScienCell Research Laboratories) supplemented with 2% FBS, 1% Pericytes Growth Supplement (PGS, ScienCell Research Laboratories) and 1% penicillin/streptomycin.
