3D Angiogenesis Assay

Angiogenesis is an incredibly intricate step in the development of a blood vessel, tightly controlled in space and time by pro- and anti-angiogenic molecules. This is important in both health and disease. Specifically, solid tumour growth and dissemination depends on angiogenesis, while other pathologies, such as atherosclerosis, are also directly dependent on angiogenesis. As a result, a variety of models have been developed to study the potential mechanisms of angiogenesis and their clinical applications. For in vitro studies, 3D modeling systems have irreplaceable advantages.

Why 3D angiogenesis?

Angiogenesis in the tumor microenvironment is a multidimensional process, with complex interactions between tumor cells, stromal cells and capillaries in the microenvironment.
In contrast to conventional 2D structures, 3D culture plates can mimic the structural and functional hallmarks of angiogenesis: endothelial cell migration, proliferation and lumen growth, branching and anastomosis.
These in vitro 3D culture systems are useful both for the discovery of new drugs and the explanation of cancer drug resistance, and are suitable for high throughput analysis.

Creative Bioarray's angiogenesis assay utilizes a cutting-edge 3D model culture system that mimics in vivo angiogenesis and allows large-scale testing of test compounds for their pro- and anti-angiogenic activity on 96-well plates.

FAQ

Q1: What is the difference between a 3D model and a 2D model?

The 3D angiogenesis assay allows you to more accurately model the 3D anatomy and cell microenvironment of tumor tissues, as well as the cell-cell interactions and the development of vascular networks, whereas 2D models are limited to a flat surface and are inadequate for studying more biological activity.

Q2: Which cells can be used in the assay?

Endothelial cells are our primary focus for angiogenesis, but we can scale the service to accommodate cell types you require for your specific research.

Q3: Does the 3D culture substrate used in the experiment comply with biosafety standards?

The 3D culture substrates we use comply with international biosafety standards to ensure the safety and reliability of the experiments.

Q4: Do you provide statistical analysis service for experimental data?

Yes, we provide professional statistical analysis services to help customers extract meaningful conclusions from experimental data.
