Abstract
Source: Cvetković, D., et al. Quantification of Breast Cancer Cell Invasiveness Using a Three-dimensional (3D) Model. J. Vis. Exp. (2014).
This video provides a detailed methodology to grow breast cancer cells in a 3D basement membrane protein matrix, exemplifying the potential of 3D culture in the assessment of cell invasion into the surrounding environment.
Protocol
1. Three-dimensional Culture of Breast Cancer Cells in Basement Membrane Matrix (The Embedment Technique) Handling Matrigel basement membrane matrix: Thaw on ice overnight at 4 °C. Basement membrane matrix is liquid at low temperature but solidifies at room temperature. Keep basement membrane matrix on ice (Figures 1A-B). Cover the Confocal No.1 glass-bottom dish with 50 μl of basement membrane matrix by means of spreading the matrix using the tip of a P-2…
