From: Quantification of dendritic cell subsets in human thymus tissues of various ages
The ratio between the medulla and cortex area in the human thymus increases with age. A, HE staining of thymus tissue slides with different ages showed medulla, cortex, and gradually increasing adipose tissue in the thymus. B, the ratio of thymic medulla area to cortical area (M/C) and the relationship between M/C and ages, the variable x in the formula is ln(M/C), n = 23
