3D tumor models are in vitro / ex vivo mimics of human tumor biology that aim to reduce and eventually replace animal tumor models in predicting efficacy and MOA outcomes in an accelerated timeline for the next generation of targeted and immunotherapies
Complex in vitro models come in many flavors – 3D spheroids, organoids, ex vivo fragments, extracellular matrix domes, engineered hydrogels, co-culture, tri-culture, and microfluidics. We at Cypre believe the ideal model combines:
(a) the complexity of human tumor microenvironment (TME) biology, including fibroblasts, immune cells, and ECM density
(b) the predictivity of a wide range of therapeutic classes (e.g. chemotherapy, targeted therapy, immunotherapy)
(c) the throughput for comprehensive and standardized analytics such as high content imaging, cytokines and flow cytometry.
To this end, we are proud to share with you the Cypre 3D tumor model platform.
Modeled by Cypre™
Tumor cells orchestrate a complex, physiologically relevant response when combined with fibroblasts and PBMCs. Key cytokines are upregulated such as SDF-1 alpha, MCP-1, IL6, and TNF-alpha, to name a few. And the propogation of 3D models in our hydrogel enable long term durability of immune phenotypes such as CD3, CD4 (T helper cells), CD8 (cytotoxic T cells), CD56 (NK cells), CD163 (M2 Macrophages), and CD19 (B cells).
Schematic of our streamlined workflow for 3D model setup and execution. Patient-derived xenograft (PDX) cells from Charles River are mouse-depleted and expanded in vitro prior to their incorporation into our proprietary hydrogel, VersaGel®, along with human fibroblasts and PBMCs. Compounds are dosed in a 6-dose, serially diluted format in 96-well plates. Efficacy readouts include tumor killing and growth delay via high content image analysis and MOA analytics such as T cell infiltration, cytokines, and immune phenotyping.
Cypre partnered with Charles River Labs to leverage their PDX models listed here for Cypre 3D tumor models. Parental PDX and PDX-derived cell lines have been genomically characterized for RNAseq and WES expression.
