Supplier: VWR International
Description: GM-CSF is a hematopoietic growth factor with the ability to form colonies of granulocytes and macrophages. Enhances the number of circulating white blood cells and function of neutrophils and monocytes. Regulates multiple functions via transcription factors in the differentiated cells, including cell survival, proliferation, and maturation. Generates in vitro murine and human DC populations from bone marrow precursors and blood monocytes, respectively.

Description: <p>Growth differentiation factor 15 (GDF-15) is a member of the transforming growth factor beta (TGF-β) family and is made by the placenta and cardiovascular tissues. GDF-15 regulates inflammatory and apoptotic pathways during cellular stress and injury. GDF-15 is emerging as a biomarker of early heart disease, such that increased levels of circulating GDF-15 are associated with an increased risk of developing heart failure. The GDF-15 D variant has a Histidine to an Aspartate substitution at amino acid position 7.</p>

Description: Placenta growth factor (PlGF) is a member of the vascular endothelial growth factor (VEGF) family and promotes endothelial cell growth and angiogenesis. PlGF is secreted as a homodimer and may also form a heterodimer with VEGF. PlGF is detected in the placenta, heart, lungs, thyroid, and adipose tissues. Circulating PlGF levels are correlated with colorectal and renal cancers, as well as atherosclerosis and ischemic heart disease. There are four alternatively spliced PlGF isoforms (PlGF-1, PlGF-2, PlGF-3, and PlGF-4), each with unique secretion patterns and heparin-binding affinities. PlGF-3 lacks a heparin-binding domain and signals through the VEGFR-1 receptor.

Description: Macrophage colony-stimulating factor (M-CSF) is a hematopoietic growth factor with broad production across different cell types (1). The regulation of monocyte and macrophage development to maintain homeostasis is primarily governed by M-CSF, which is generated by stromal cells present in both the bloodstream and tissues. Mature mononuclear phagocytes, in response, possess CSF-1 receptors (CSF-1R) and eliminate circulating CSF-1. This process creates a feedback mechanism responsible for diminishing monocyte proliferation (2, 3, 4). M-CSF also exerts its effects by interacting with CSF1R, influencing various processes related to immunology, bone health, fertility, and pregnancy regulation (5). Human M-CSF has cross reactivity to mouse cells, whereas mouse M-CSF does not exhibit activity on human cells (6).
