A. Phase-contrast micrograph of the HUH-7, HUVEC, and BM-MSCs cells (a-c). B. Micrograph of 3D HUH-7 organoids and C. 3D Mixed organoids, (a) stained with Calcine AM (b) Hoechst (c) and merged (d) H & E stained cryosections show the structure and lumen (*) of the 3D Mixed organoids surrounded by a network of stromal cells (e). D. Flow cytometry analysis of cell viability using propidium iodide staining. (a) HUH-7 organoids (b) 3D Mixed organoids after 14 days. E. RT-qPCR shows relative levels of expression of cell cycle regulator (CCNA1, CCNB1, CCND, and CCNE), proliferation (BAX, BCL2), and apoptosis genes (P21, P53, APAF1) in HUH-7 2D, 3D HUH-7, 3D Mixed, and HCC tissue. Values represent relative gene expression mean ± SD. *p < 0.05, **p < 0.01, and ***p < 0.001 respectively
