a Phase-contrast and anti-laminin staining images of ablated regions with different laser power densities. The green region indicates intact laminin, which was originally below the hydrogel and then revealed after agarose ablation. Scale bar: 50 μm. The images shown are representative of three independent experiments. b Ablated width of agarose hydrogel against power density. n = 9 ablated lines. Data are presented as mean ± SD. c Immunostained images of extended neurites along the ablated lines (green: MAP2, somatodendritic marker; red: tau-1, axonal marker). Scale bar: 100 μm. The images shown are representative of two independent experiments. Source data are provided as a Source Data file.
