WebInhibit immunity (T cell function) Tumor-derived osteopontin suppresses antitumor immunity by promoting extramedullary myelopoiesis. In this study, we found that osteopontin expressed by tumor cells enhances extramedullary myelopoiesis in a CD44-dependent manner through the Erk1/2-MAPK pathway. 25035397. WebMyelopoiesis. Myelopoiesis is defined as the development of non-lymphoid leukocytes. The stages of myelopoiesis are variable among species, cells types, and model system. Generally speaking, monocytes/macrophages, granulocytes, and mast cells arise from a common myeloid progenitor (humans) or a granulocyte/monocyte progenitor (mice). dr thierry novello https://creafleurs-latelier.com
