a Fluorescence images of the axons in the regions near and far away from the astrocytes on day 1, day 4, day 7, and day 14 (Scale bar: 50 μm); b A comparison of the number of short, long, and medium axons and the total number of axons in the N and F groups in the N&G-L group (N denotes the regions near the astrocytes; F denotes the regions far from the astrocytes, n = 4; Long: axons > 100 μm; middle: axon = 50–100 μm; short: axons = 0–50 μm (*p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001)
