Thymus mesenchymal stromal cells (MSCs) increase the rate of self-organization of cardiomyocytes. Thymus MSCs were added in increasing concentrations to 1 × 106 cardiomyocytes and allowed to self-organize in a custom culture dish. (A) Day 2 after plating, fibers containing more MSCs were more self-organized as compared with controls without MSCs. (B) Graphic representation of self-organization as a function of time and number of MSCs. Fibers with more MSCs self-organized more rapidly (n = 3/group).
