A) Clustered (DCCs) and layered-continuous DLK1 expression in physiologically normal human adrenals are expressed as percentage of total cortical DLK1 staining in each age group. Error bars represent standard error of the mean, two-way ANOVA: * (p < 0.05), *** (p < 0.001) B) Quantitative analysis of the size of DCCs with age. Pearson correlation test. C) Percentage of total DLK1 staining expressed as percentage of DLK1 staining/total cortical area showing a non-significant trend of reduction of DLK1 positivity up to approximately 60 yo. ns, not significant. For A–C (also applicable to Fig. 1), n = 11 (FAs), 7 (0–25 yo), 6 (26–40 yo), 5 (41–50 yo), 6 (51–60 yo), 8 (61–70 yo).
