Has anyone co-cultured cancer cells with muscle cells to study their potential interaction? And which cell lines and systems would be appropriate to use?
Very intriguing experimental designs can be considered in your experiment!!!
For example, why not set up the extracellular matrix (ECM) such as matrigel or collagen layer between tumor cell zones and muscle layer? Tumor cells have to exhibit the invasion into the muscle tissue before destroying the ECM as described in the below figure.
