We present here the effect of extracellular matrix (ECM) on the proliferation and physiology of HL-1 cardiac cells. HL-1 cell is from AT-1 mouse atrial cardiomyocyte tumor lineage. HL-1 cell can be serially passaged, yet they maintain the ability to contract which is a promising character of HL-1 cell for the cell based biosensors. HL-1 cells grow up on the ECM which can affect on the attachment and growth of HL-1. In this paper, we discuss HL-1 cell-ECM interactions with three different ECMs and non-treated surface. HL-1 cells are grown for 4 days after seeding then observed their attachment. Also they were immunostained by hoechst and EthD-1 for proliferation, phalloidin for Factin, and DAPI for nuclei. Fibronectin was revealed as the proper ECM material for HL-1 cell culture. This study can provide basic information for understanding the cell-ECM interactions and growth of HL-1 cells.
