(
A) Representative examples of somatosensory cortex LII/III pyramidal neurons filled with biocytin in control (P24) and ΔNp73
cre/+;R26
Kir2.1/+ (P27) mice. (
B) Quantification of number of dendritic branches of LII/III pyramidal neurons in controls and ΔNp73
cre/+;R26
Kir2.1/+ mice, expressed as a percentage relative to the mean of controls (apical dendrites n = 7 for controls and n = 9 for mutants at P23-P29, p=0.550; basal dendrites n = 7 for controls and n = 8 for mutants at P23-P29, p=0.199; Mann-Whitney U Test). (
C) Sholl analysis for the apical and basal dendrites in control and ΔNp73
cre/+;R26
Kir2.1/+ mutant mice showing no significant change in cell complexity with respect to the distance from the soma, (apical dendrites n = 7 for controls and n = 9 for mutants; basal dendrites n = 7 for controls and n = 8 for mutants). Multiple T-test. Scale bar represents 100 μm. Data used for quantitative analyses as well as the numerical data that are represented in graphs are available in
