The average dynamic response of the spheroid area and circularity for each condition.

<p>(A), (B) Average response of the area for the two agarose types, respectively for the small- and large-sized spheroids. (C), (D) Average response of the circularity for the two agarose types, respectively for the small- and large-sized spheroids. (E), (F) Images of the cell aggregation process over time for the two agarose types, respectively for the small- and large-sized spheroids. The black scale bars represent 200 μm.
