Thymohexine treatment of intact CFU-S was shown not to change their capacity to form
colonies both in vivo and in vitro. Thymohexine, similarly to thymus cells, increased colony …

Whether accessory T cells can be replaced by the synthetic immunomodulators thymogen
(Glu-Trp) and thymohexin (Arg-Lys-Asp-Val-Tyr-Arg) was studied. The latter …

The study investigates the effect of humoral factor isolated from calf-thymus (thymosin) upon
regeneration of lymphatic and haemopoietic tissues of female (CBA times C57BL/10ScSn) …

In vitro incubation of spleen cell suspensions in dilutions of anti-thymocyte globulin (ATG)
leads to abrogation of the capacity of such cells to mount a graft-vs-host reaction; however …

Following transplantation of bone marrow into recipient mice subjected to irradiation with
four weekly fractions of 1.8 Gy, donor progenitor cells were found to compete with host …

This study reports on the in vivo effects of thymustimulin (TST), a thymic extract, on the
hematopoiesis of mice treated with cyclophosphamide (CTX). Peripheral blood counts and …

It is well established that normal lymphopoiesis in the adult thymus is dependent upon the
existence of an intact pool of pluripotent stem cells in the bone marrow. The factors which …

Natural killer (NK) activity and interferon (IFN) production of spleen and bone-marrow
lymphocytes were investigated in 8 to 10-wk-old C3HeB/FeJ/Cne mice, before and after in …

The hypothesis that cells located in mouse bone marrow can acquire immunological
competence by a process that involves interaction with a noncellular component of the …

Highly purified calf thymus preparations were obtained by sulfuric acid extraction procedure.
These were further purified by ion-exchange chromatography on a CM-cellulose column …
