[Factors controlling the recirculation of hematopoietic stem cells. IV. The effect of thymosin on the migration and differentiation of hematopoietic stem cells]

Abstract

Thymosine, a thymus hormone, restores the thymectomy induced deterioration of the routine pathways of migration and differentiation ofhemopoietic stem cells in mice. Administration of thymosine together with bone marrow cells from thymectomized mice to irradiated recipients also restores the level of migration and differentiation of hemopoietic stem cells. The inducing effect of thymosine on the maturation of T-lymphocyte precursors, which in their turn restore the usual rate of migration and differentiation of hemopoietic stem cells, has been suggested.
