Extended Data Fig. 2. Intravital 2-photon imaging does not affect proliferation or lineage commitment of Gli1-targeted NSCs.

Extended Data Fig. 2

a, Explanatory scheme of the different parameters extracted from lineage data of the imaged clones. b, Comparison of cell proliferation in contralateral and ipsilateral side in Gli1 mice after 2 months of 2-photon imaging (dorsal DG, horizontal sections). c, Quantification of Ki67+ cells and Ki67+ tdTom+ cells in contra- and ipsilateral side. Horizontal sections, first 360 μm of DG are considered (Ki67+ ipsilateral: 1345 ± 235.7, n = 3 mice; Ki67+ contralateral: 1278 ± 252.2, n = 3 mice; Paired t-test: t = 0.2631; df = 2; p = 0.817, two-tailed. Ki67+/tdTom+ ipsilateral: 28 ± 11.06, n = 3 mice; Ki67+/tdTom+ contralateral: 68.33 ± 26.1, n = 3 mice; Paired t-test: t = 2.678; df = 2; p = 0.116, two-tailed). d, Percentage of Ki67+ tdTom+/tdTom+ cells in contra- and ipsilateral side (ipsilateral: 7.26 ± 1.84, n = 4 mice; contralateral: 8.58 ± 0.63, n = 4 mice; Paired t-test: t = 0.895; df = 3; p = 0.436, two-tailed). e, Percentage of tdTom+ Hopx+ Ki67+/tdTom+ Hopx+ cells in contra- and ipsilateral side (ipsilateral: 9.0 ± 1.83, n = 3 mice; contralateral: 9.63 ± 1.91, n = 3 mice; Paired t-test: t = 0.392; df = 2; p = 0.733, two-tailed). f, Comparison of the number and identity of tdTom+ cells in contralateral and ipsilateral side in Gli1 mice after 2 months of 2-photon imaging (dorsal DG, horizontal sections). g, Quantification of tdTom+ neurons and Sox2+ tdTom+ glial cells in contra- and ipsilateral side. Horizontal sections, first 360 μm of DG are considered (tdTom+ ipsilateral: 475.3 ± 45.16, n = 3 mice; tdTom+ contralateral: 424.7 ± 128.2, n = 3 mice; Paired t-test: t = 0.475; df = 2; p = 0.681, two-tailed. tdTom+ SOX2+ ipsilateral: 279.3 ± 36.5, n=3 mice; tdTom+ Sox2+ contralateral: 293 ± 75.5, n = 3 mice; Paired t-test: t = 0.345; df = 2; p = 0.762, two-tailed). h, Percentage of Sox2+ tdTom+/tdTom+ in contra- and ipsilateral side (ipsilateral: 36.93 ± 3.78, n = 3 mice; contralateral: 41.49 ± 2.49, n = 3 mice; Paired t-test: t = 1.347; df = 2; p = 0.31, two-tailed). i, Quantification of the DG area covered by GFAP+ cells/area tot in Gli1 contra- and ipsilateral side at 2 weeks after surgery (ipsilateral: 0.77 ± 0.03, n = 3 mice; contralateral: 0.73 ± 0.01, n = 3 mice; Paired t -test: t = 2.004; df = 2; p = 0.183, two-tailed). j, Quantification of the DG area covered by Iba1+ cells/area tot in Gli1 contra- and ipsilateral side at 2 weeks after surgery (ipsilateral: 0.51 ± 0.05, n = 3 mice; contralateral: 0.5 ± 0.04, n = 3 mice; Paired t-test: t = 0.677; df = 2; p = 0.568, two-tailed). k, Quantification of the DG area covered by GFAP+ cells/area tot in Gli1 contra- and ipsilateral side at 2.5 months after surgery (ipsilateral: 0.79 ± 0.03, n = 3 mice; contralateral: 0.83 ± 0.02, n = 3 mice; Paired t-test: t = 1.654; df = 2; p = 0.24, two-tailed).
