Biochem/physiol Actions

Interleukin-3 (IL-3) is a multifunctional protein, originally called colony forming unit-stimulating activity (CFU-SA), and is produced by activated T lymphocytes. IL-3 supports the formation of multilineage colonies in the early development of multipotent hematopoietic progenitor cells. IL-3 has been shown to induce colony formation of macrophages, neutrophils, mast cells, and megakaryocytes from agar-suspended bone marrow cells. IL-3 also interacts with IL-2 to stimulate growth of T lymphocytes and to induce IgG secretion from activated B cells. Other synonyms for IL-3 include pan-specific hemopoietin, multicolony stimulating factor, mast cell growth factor, burst promoting activity, histamine-producing cell stimulating factor, P cell stimulating factor, and WEHI-3 factor.

Physical form

Lyophilized with no additives. Sterile filtered through a 0.2 μm filter.

Analysis Note

The biological activity is measured by the dose-dependent stimulation of the proliferation of human TF-1 cells.

Ribosomal protein dysfunction causes diverse human diseases, including Diamond-Blackfan anemia (DBA). Despite the universal need for ribosomes in all cell types, the mechanisms underlying ribosomopathies, which are characterized by tissue-specific defects, are still poorly understood. In the present study, we

The role of SET domain containing 7 (SETD7) during human hematopoietic development remains elusive. Here, we found that deletion of SETD7 attenuated the generation of hematopoietic progenitor cells (HPCs) during the induction of hematopoietic differentiation from human embryonic stem cells

Basophils are primarily associated with immunomodulatory functions in allergic diseases and parasitic infections. Recently, it has been demonstrated that both activated human and mouse basophils can form extracellular DNA traps (BETs) containing mitochondrial DNA and granule proteins. In this report

Treatment with erythropoietin (EPO) in several cancers is associated with decreased survival due to cancer progression. Due to the major importance of telomerase in cancer biology we hypothesized that some of these effects may be mediated through EPO effect on

Impaired megakaryocyte maturation and insufficient platelet production have been shown to participate in the pathogenesis of immune thrombocytopenia (ITP). Our previous study demonstrated that low expression of tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) in megakaryocytes contributed to impaired platelet production
