3d-1d Multidimensional Cancer-on-a-chip

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a specialized lab-on-a-chip device, called a "3D-1D Multidimensional Cancer-on-a-Chip," designed to analyze single tumor cells in vitro. It works by capturing tumor cells in tiny, hydrogel-based microcapsules that mimic the physical properties of real tumors. As the cells are released from these capsules, they migrate onto narrow, one-dimensional paths made of biological materials similar to those found in the human body. This setup enables researchers to study the behavior of individual cancer cells as they move from a 3D (tumor-like) environment to a 1D (migration path), closely simulating the progression and spread of cancer in the human body.

Use CasesContent extracted from patent full text and abstract with AI.

• Personalized drug testing and screening for cancer therapies using patient-derived tumor cells.
• Detailed study of tumor cell migration, heterogeneity, and metastatic potential at the single-cell level.
• Separation and analysis of tumor cells from mixed cell populations such as biopsies, without the need for prior purification.
• High-throughput drug screening and cytotoxicity testing to evaluate new anti-cancer agents in an environment that mimics in vivo conditions.
• Long-term, dynamic studies of cancer cell behavior in response to drugs, biological or physical stimuli.
• Reducing animal use in preclinical cancer research by providing a more accurate in vitro model.

BenefitsContent extracted from patent full text and abstract with AI.

• Closely mimics the mechanical and topographical environment found in real tumors, enabling more physiologically relevant studies.
• Allows single-cell resolution analysis, capturing cancer cell heterogeneity and unique behaviors lost in bulk assays.
• Selective for tumor cells—the device enables discrimination and separation of tumor cells from healthy cells.
• Flexible and modular system design allows customization to specific research needs (different cell types, migration paths, mechanical properties, etc.).
• Supports dynamic and prolonged experiments, including real-time monitoring and time-lapse studies.
• Can be applied directly to cells from human biopsies, reducing the need for pre-isolation or expansion and saving time/resources.
• Potentially reduces reliance on animal models for cancer research and drug development, supporting ethical research approaches.

Patent Abstract

The present invention relates to an apparatus for analyzing single tumor cells, said apparatus comprising a hydrogel-based polymeric microcapsule for entrapping cells and a hydrogel having on its surface a single cell migration path being formed by one or more extracellular matrix proteins and/or one or more polymers comprising RGD peptides or proteins, wherein the polymeric microcapsule and the path are placed in the apparatus such that upon the release of cells from the polymeric microcapsule a single tumor cell can migrate from the polymeric microcapsule on the path.
