Bridges the gap between 2D cell culture and animal models
This technology is a new 3D bioprinted method to create in vitro tumor models. The 3D printed microenvironments reconstruct the chemical, physical and/or spatiotemporal aspects of native biological microenvironments. The design incorporates the vasculature and stromal elements involved in tumor microenvironments (e.g., tumor cells, fibroblasts and blood vessels). In addition, the technology has integrated spatiotemporal control of tumor cell migration and angiogenesis by creating chemical gradients of growth factors using 3D printed stimuli-responsive capsules.The model provides tools for understanding the mechanism of cancer metastasis, for drug screening and testing patient specific therapies.
Models tumor cell migration and other complex cell behaviors
Many anticancer drugs succeed in cell culture yet fail in pre-clinical testing because “drug-in-a-dish” assays doesn’t replicate the complexity of a tumor’s microenvironment. Conventional 2D monolayer cell cultures cannot accurately mimic characteristics of native tumor microenvironments, and current 3D cultured tumor cells, while able to more closely mimic natural behaviors, still cannot model the tumor microenvironment. This new 3D bioprinted platform helps bridge the gap between 2D cell cultures and animal models. The 3D models establish physiological cell–cell, cell–extracellular matrix (ECM) and cell–chemical signal interactions with precise spatiotemporal resolution. In addition, the constructs consist of human cells, rendering them more clinically relevant and versatile with the option to incorporate a patient's own cells for precise selection of effective therapies.
