Immunofluorescence expression of key proteins at each stage and Glucose stimulation release experiment in vitro; each sample in triplicates from three independent experiments. A Immunofluorescence expression of key proteins at each stage; all images are magnified 100×; B glucose stimulation release experiment in vitro; ** indicates p < 0.05; the difference is statistically significant. All images have a resolution of 300dpi. All images are made using Photoshop. The intensity of Merge’s fluorescence signal was adjusted
