Fig. 4. Effect of concave diameter on spheroid size. (A) Phase-contrast images of spheroids created in concave with diameter of 500 μm, 750 μm, 1000 μm at day 2, 4, 6, 8. Scale bar = 500 μm. (B) The average diameter of spheroids cultured in 500 μm, 750 μm, 1000 μm concave microwells. (C) Size distribution of spheroids cultured in 1000 μm concave microwells after 8 days.
