From: Genetic and non-genetic determinants of thymic epithelial cell number and function

Functional characteristics of thymopoiesis in different mouse strains. (a) Number of thymic epithelial cells (TECs) in mice at 10 weeks of age. F1 denotes a hybrid between CBA/J and PWK/PhJ. (b) Number of CD45+ thymocytes. (c) Thymopoietic indices, calculated as dimensionless thymocyte/TEC ratios. (d) Non-linear relationship between thymocyte and TEC numbers; all mice were pooled for this analysis. In (a) to (c), means ± s.e.m.
