Figure 1From: TSLP is involved in expansion of early thymocyte progenitorsTSLP enhances early thymopoiesis in mouse fetal thymic organ culture. E15 fetal thymus organs were cultured with different doses of TSLP (10, 30 or 100 ng/ml) (A) for 2 weeks. Total thymocytes were harvested and counted. B, TSLP increased the relative frequencies of CD4-CD8- (DN) and CD4-CD8+ thymocytes in FTOC. C, TSLP preferentially increased the number of DN thymocyte cells. Shown are representative data from at least 4 independent experiments. Standard deviation (SD) is shown as error bars. *: P < 0.05, * *: P < 0.01, compared with medium control.Back to article page
