a Dorsal root ganglion cells were cultured in fibrin hydrogels containing 6% superparamagnetic iron oxide nanoparticles (SPIONs) and PLLA fibers. Dorsal root ganglion cells were labeled with RT-97 for neurofilament, white dotted lines Indicates the area with nerve fibers, and the white arrow indicates the three longest neurites. b Histograms showing the distribution of neurite growth angles (±180°), Each bar represents a 10° bin (% of total)
