Figure Lengend Snippet: Synthesis and characterization of BA-HPCS@CGRP microspheres based on microfluidic fabrication. A. Fourier transform infrared spectroscopy spectra of the HPCS, 3-Carboxyphenylboronic acid (BA), and BA-HPCS. B. The hydrogel precursors appear as a liquid macroscopically before gelation. C. The hydrogels appear milky white after photo-crosslinking. D. The imaging of BA-HPCS@CGRP microspheres based on microfluidic chips: macroscopic and microscopic observations. E. Particle size distribution of BA-HPCS@CGRP microspheres. F and G. Representative scanning electron microscope images of BA-HPCS@CGRP microspheres. H. The pore size distribution of lyophilized BA-HPCS@CGRP microspheres. I. The releasing of CGRP from BA-HPCS@CGRP in PBS and different glucose conditions (100 mg/dL, 400 mg/dL). J. Representative live/dead fluorescence images of L929 cells after co-culture with microspheres (green calcein-AM for live cells, red propidium iodide for dead cells). K. The quantitative analysis of L929 cell viability co-cultured with microspheres. ns, no significance. ∗∗∗ p < 0.001; ∗∗ p < 0.01; ∗ p < 0.05; ns, no significance.
