(a) Isolation of Dlxi1/2b::eGFP+ cells for
transcriptional analysis. (b) t-SNE visualization of single cell
gene expression at day 121 (4 weeks after hSS-hCS assembly). (c)
Distribution across clusters (χ2-test,
χ2= 43.39, P< 0.0001). (d)
Expression of ERBB4, NXPH1, IGF1,
TCF4, FOS, RAD1. (e)
Morphology of Dlxi1/2b::eGFP+ cells before and after
migration into hCS (f) Action potential generation in
Dlxi1/2b::eGFP+ cells (one-way ANOVA, F(2, 30)=
1.25; ***P< 0.001; Bonferroni post-hoc,
**P< 0.01; ***P< 0.001).
(g) GABAergic synapse (by AT) on the pallial side of hCS-hSS
with SYN1, GPHN and VGAT. (h) EPSCs and IPSCs in
Dlxi1/2b::eGFP+ cells after migration. (i)
Synaptic responses in Dlxi1/2b::eGFP+ cells (two-way ANOVA,
interaction F(2, 61)= 18.46, P< 0.0001; Bonferroni post-hoc for
EPSCs, ***P< 0.0001,
**P< 0.001). (j) Synaptic responses in
excitatory cells (two-way ANOVA, cortical neurons in hCS before and after
assembly F(1, 26)= 5.6, P< 0.05; Bonferroni post-hoc for IPSC,
*P< 0.05).
