Hemopoieitc Spleen Colony Studies
The polycythemic repression of erythropoiesis and the restoration of erythropoiesis by specific stimulation were studied in the spleen colony system in irradiated mice. 1. A 5 day period of erythropoietin stimulation (exogenous erythropoietin) or repression (polycythemia) of the bone marrow donor only, does not significantly alter the number or type of colonies formed by the transplanted marrow...
متن کاملHemopoietic Spleen Colony Studies
The effects of phytohemagglutinin (PHA) were studied in irradiated mice to see if a definite myeloproliferative effect could be demonstrated in vivo. The data obtained suggested the following conclusions. PHA treatment of the bone marrow donor only, causes a consistent but slight reduction in transplantable spleen colony-forming unit (CFU) content of the bone marrow 24 hr after the last PHA inj...
متن کاملSpleen: Case Studies
The aim on this lecture is to present a pragmatic diagnostic guide to tumorous lesions in the spleen, whether reactive or neoplastic and not to provide an update or a compendium of the disorders that commonly involve the splenic white and red pulp. The lecture is based on four case studies that are employed to illustrate a practical approach to solving the issue of newly discovered splenic mass...
متن کاملHemopoietic Colony Studies
In heavily irradiated mice, bone marrow regeneration of either endogenous or exogenous origin was shown to occur in discrete foci comparable to the more intensively studied spleen colonies. The number of endogenous bone marrow colonies was inversely related to dose of whole body X-irradiation. Endogenous marrow colonies were found after higher doses of irradiation than were endogenous spleen co...
متن کاملSTUDIES ON THE TISSUE SPECIFICITY OF COLONY STIMULATING FACTOR
In this study granulocyte-macrophage colony stimulating factor (CSF) was prepared from rabbit and guinea pig lung tissues. The biological activity of these CSFs was measured on semisolid agar culture and compared with those of mouse and rat. Weight of animals, incubation time and cross-reactivity of CSFs with different bone marrow sources were also investigated. The results showed that both...
