Human brain organoids (HBOs) derived from pluripotent stem cells hold great potential for disease modeling and high-throughput compound screening, given their structural and functional resemblance to fetal brain tissues. These organoids can mimic early stages of brain development, offering a valuable in vitro model to study both normal and disordered neurodevelopment. However, current methods of generating HBOs are often low throughput and variable in organoid differentiation and involve lengthy, labor-intensive processes, limiting their broader application in both academic and industrial research.

Human liver organoids (HLOs) derived from pluripotent stem cells hold potential for disease modeling and high-throughput compound screening due to their architectural and functional resemblance to human liver tissues. However, reproducible, scale-up production of HLOs for high-throughput screening (HTS) presents challenges. These include the high costs of additives and growth factors required for cell differentiation, variability in organoid size and function from batch to batch, suboptimal maturity of HLOs compared to primary hepatocytes, and low assay throughput due to excessive manual processes and the absence of assay-ready plates with HLOs.

Recent advancements in three-dimensional (3D) cell culture technologies, such as cell spheroids, organoids, and 3D bioprinted tissue constructs, have significantly improved the physiological relevance of in vitro models. These models better mimic tissue structure and function, closely emulating in vivo characteristics and enhancing phenotypic analysis, critical for basic research and drug screening in personalized cancer therapy. Despite their potential, current 3D cell culture platforms face technical challenges, which include user-unfriendliness in long-term dynamic cell culture, incompatibility with rapid cell encapsulation in biomimetic hydrogels, and low throughput for compound screening.
