MetabolomicsLiquid chromatography coupled to high-resolution mass spectrometry metabolomics: A useful tool for investigating tumor secretome based on a three-dimensional co-culture model

Three-dimensional (3D) cell culture technologies, which more closely mimic the complex microenvironment of tissue, are being increasingly evaluated as a tool for the preclinical screening of clinically promising new molecules, and studying of tissue metabolism. Studies of metabolites released int...

MetabolomicsOrganotypic microfluidic breast cancer model reveals starvation-induced spatial-temporal metabolic adaptations
BACKGROUND: Ductal carcinoma in situ (DCIS) is the earliest stage of breast cancer. During DCIS, tumor cells remain inside the mammary duct, growing under a microenvironment characterized by hypoxia, nutrient starvation, and waste product accumulation; this harsh microenvironment promotes genomic in...

TranscriptomicsGene expression profile of A549 cells from tissue of 4D model predicts poor prognosis in lung cancer patients
Tumor microenvironment plays an important role in regulating cell growth and metastasis. Recently we developed an ex vivo lung cancer model (4D) that forms perfusable tumor nodules on a lung matrix that mimics human lung cancer histopathology and protease secretion pattern. We compared the gene ex...

ProteomicsProteome comparison of a new human cholangiocarcinoma 3D co-culture tumor model to 3D single cultures.
Cholangiocarcinomas (CCA) are characterized by their desmoplastic and hypervascularized tumor microenvironment (TME) which is mainly composed of tumor cells and cancer-associated fibroblasts (CAFs). CAFs play a pivotal role in tumor progression, angiogenesis, metastasis and the development of therap...

MetabolomicsEffects of hypoxic preconditioning on neuroblastoma tumour oxygenation and metabolic signature in a chick embryo model
Hypoxia episodes and areas in tumours have been associated with metastatic dissemination and poor prognosis. Given the link between tumour tissue oxygen levels and cellular metabolic activity, we hypothesised that the metabolic profile between metastatic and non-metastatic tumours would reveal poten...

ProteomicsExtracellular vesicles secreted by 3D tumor organoids are enriched for immune regulatory signaling biomolecules compared to conventional 2D glioblastoma cell systems
Background: Newer 3D culturing approaches are a promising way to better mimic the in vivo tumor microenvironment and to study the interactions between the heterogeneous cell populations of glioblastoma multiforme. Like many other tumors, glioblastoma uses extracellular vesicles as an intercellular c...

TranscriptomicsGene expression profile of A549 Circulating Tumor Cells from 4D Model.
CTCs in cancer patients are thought to be responsible for metastasis. Currently, there is no ex vivo model that can isolate this group of cells. We have developed an ex vivo 4D lung cancer model that forms perfusable tumor nodules and form CTCs. Gene array analyses show 2504 differentially expressed...

ProteomicsA Vascularized Three-Dimensional Breast Cancer Model: Mimicking the Tumor Microenvironment and Chemoresistance
Tumorigenesis is a complex and dynamic process in which the tumor microenvironment (TME) plays a central role. In solid tumors, the TME contributes to key mechanisms of tumor progression, including metastasis, immune evasion, and resistance to therapies. One major challenge in preclinical cancer res...

ProteomicsHigh throughput microfluidic 3D biomimetic model enabling quantitative description of human breast tumor microenvironment
Cancer is driven by genetic aberrations in the tumor cells and fundamental changes in the tumor microenvironment (TME). These changes offer potential targets for novel therapeutics, yet lack of in vitro 3D models recapitulating this complex microenvironment impedes such progress. Here, we generated ...

In vitro cell culture studies are common in cancer research field, and reliable biomimetic 3D models are needed to ensure physiological relevance. In this manuscript, we hypothesized that decellularized xenograft tumors can serve as an optimal 3D substrate to generate a top-down approach for in vitr...
