Cardiac diseases are the most prominent cause of death worldwide. Cardiomyocyte regeneration is imperative, due to the human body lacking in the ability to sufficiently regenerate cardiomyocytes (CMs). One-way cardiomyocytes can be regenerated is through differentiating human induced pluripotent stem cells(hiPSCs) into cardiomyocytes. In order to attach hiPSCs derived-cardiomyocytes in a manner that would mimic native conditions, various techniques can be used, such as microcontact printing. The microcontact printing technique allows for a specified geometry or pattern to be transferred onto the substrate that will be used for cardiomyocyte seeding. The pattern utilized in this study comes from the rectangular-pillared-array stamp. The preliminary results show that a general cell line of mouse embryonic fibroblasts (MEFs) can be constrained to this pattern.
