Transient populations of TdT+ cells are present in peripheral blood, lung, liver, and spleen of rats and mice between birth and 7 wk of age. TdT+ blood cells appear to be post-thymic cells, as evidenced by their absence from nu/nu mice and their pattern of TdT fluorescence. TdT+ cells in lung, liver, and spleen appear to be prethymic cells. All transient populations of TdT+ cells are sensitive to dexamethasone. Only TdT+ cells in bone marrow and thymus persist into adult life.
在出生至7周龄的大鼠和小鼠的外周血、肺、肝和脾中存在短暂的末端脱氧核苷酸转移酶（TdT）阳性细胞群。TdT阳性血细胞似乎是胸腺后细胞，这在裸鼠中不存在以及它们的TdT荧光模式中得到证明。肺、肝和脾中的TdT阳性细胞似乎是胸腺前细胞。所有短暂的TdT阳性细胞群对地塞米松敏感。只有骨髓和胸腺中的TdT阳性细胞持续到成年期。
