Optimization of the size of gelatin microspheres for the MCO fabrication. a. The statistical summary of follicle diameters cultured in different sizes of cavities, n > 8, the error bar stands for standard error of the mean, the p-value passed two-way ANOVA test, ns: p > 0.05; *: p < 0.05; **: p < 0.01. b. Folliclular growth and ovulation in different sizes of cavities created by gelatin microspheres, the bar was 200 μm. c. The distribution of follicle diameters cultured in different sizes of cavities, the p-value passed the Chi-square test, ****: p < 0.0001.
