Fig. 1: Heterogeneous high-grade serous ovarian tumoroids were created with 23 different cell compositions.

A Bar graph showing the total cell number in each tumoroid composition distributed between high-grade serous cell line OVCAR3 (blue), mesenchymal stem cells (MSCs) (red), endothelial cells (ECs) (green), and U937 monocytes (purple). B Bar graph showing the percentage of each cell type in each composition, with OVCAR3 represented in blue, MSCs in red, ECs in green, and U937 monocytes in purple. C Phase contrast image of tumoroids taken on day 5, made with each cell composition showing heterogeneous size and morphology. Scale bar = 200 μm.
