Issue Title: This issue is a translation of Byulleten Eksperimentalnoi Biologii i Meditsiny (Bulletin of Experimental Biology and Medicine) and Kletochnye Tekhnologii v Biologii i Meditsine (Cell Technologies in Biology and Medicine) The efficiency of cloning of stromal precursor cell increased more than 2-fold in splenic cultures and more than 3-fold in bone marrow cultures 24 h after injection of Profetal preparation to mice in vivo. The number of nucleated cells did not change in the bone marrow and slightly increased in the spleen. Addition of Profetal in vitro 2-fold decreased the efficiency of stromal precursor cells colony formation in mouse splenic cultures and dose-dependently decreased this process in bone marrow cultures derived from these animals, the maximum (5-fold) inhibitory effect was observed in a dose of 50 µg/ml. Addition of Profetal to cultured human bone marrow fibroblasts did not change the content of stromal fibroblasts in cultures. These data indicate the possibility of indirect effect of α-fetoprotein on the number of stromal precursor cell in hemopoietic and lymphoid organs.
