A device for aggregating cells includes a cavity. The cavity includes a plurality of microwells for receiving at least one cell. Each of the microwells includes a vertical sidewall and a curved bottom. The microwells are made in a hydrogel layer. Each of said microwells has a diameter and an interwell distance between one microwell and another microwell, wherein a ratio for the interwell distance to the diameter is less than or equal to 1/10.
