From: TSLP is involved in expansion of early thymocyte progenitors
TSLP and IL-7 both enhances early T progenitor cells and thymopoiesis in mouse fetal thymic organ culture. E15 fetal thymus organs were cultured with either TSLP (30 ng/ml) and/or IL-7 (100 ng/ml) for 2 weeks. Total thymocytes were harvested and counted (A). Thymocytes that were negative for expression of CD3/CD4/CD8 were further analyzed for DN subpopulation based on the expression of CD44 and CD25 (B). The data is a summary of 2 independent experiments. Standard deviation (SD) is shown as error bars. *: P < 0.05, * *: P < 0.01, compared with medium control.
