^*p < 0.0001 ^ap = 0.65 ^bp = 0.42 ^cp = 0.0004 compared with human. Islet size is described as an effective diameter of a circle, which depicts the same area as a measured islet area. β-cell ratio is the area ratio of β-cells in an islet. Both data sets are expressed as the mean value with its standard deviation.
