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 chemical
