crMPD™: Cold Responsive MicroPatterned Dish

Culture dish that enables production of human induced pluripotent stem cell (iPSC, or other pluripotent stem cell) colonies of a homogeneous size (e.g., 100, 200, 300, or 400  um in diameter) for 3D culture with ~100% viability and high quality, without using any chemicals like Versene or ROCK inhibitor that compromises the iPSC quality. The colonies can be conveniently detached by simply putting the crMPD™ on ice for 10-15 min without using any chemica
