Sensory functions of aged mice are improved by engraftment of GPC-derived astrocytes in the somatosensory cortex. A Schematic illustration of the experimental protocol used for testing escape response latency. B Response traces of mice after footshock stimulation (grey bar) in adult-control, aged-control, and aged-engrafted mice groups. C Summary of escape response latencies in adult-control, aged-control, and aged engrafted mice group (n = 6 mice per group; Adult-control versus Aged-control, P = 0.0401; Aged-control versus Aged-engrafted, P = 0.0022; Adult-control versus Aged-engrafted, P = 0.5265; *P < 0.05, **P < 0.01, two-way ANOVA with Bonferroni post hoc comparisons test). All data in the figure are shown as mean ± s.e.m.
