Descrição: Bone morphogenetic protein 2 (BMP-2) is a member of the transforming growth factor beta (TGF-β) superfamily. BMP-2 is a disulfide-linked homodimer, acts as a ligand for complexes of type I and II BMP receptors, and primarily activates SMAD1/5/8 signaling (Nohe <i>et al.</i>). BMP-2 is a potent differentiation factor and directs human pluripotent stem cells (hPSCs) towards various cell types including extra-embryonic endoderm, mesenchymal cells, and chondrocytes (Pera <i>et al.</i>). Although BMP-2 expression is low in healthy cartilage, its expression is upregulated at the site of cartilage damage (Blaney Davidson <i>et al.</i>). BMP-2 induces bone and cartilage formation in vitro and is able to induce chondrogenesis in human mesenchymal stem cells (Schmitt <i>et al.</i>). This product is animal component-free.

Descrição: Interleukin 1 alpha (IL-1α) is a member of the IL-1 family and a dual-function cytokine. Both the unprocessed precursor and a processed IL-1α protein signal through IL-1 receptor type 1 (IL-1R1). Various cells, including keratinocytes, thymic epithelium, hepatocytes, endothelial cells, fibroblasts, and the epithelial cells of mucous membranes, have high levels of intracellular IL-1α precursor. The precursor is also expressed on the surface of monocytes and B lymphocytes (Netea <i>et al.</i>). IL-1α recruits infiltrating cells to a site of injury during necrosis and plays an important role during processes of sterile inflammation (Cohen <i>et al.</i>; Rider <i>et al.</i>). During hypoxia, IL-1α contributes to angiogenesis (Carmi <i>et al.</i>). Studies in mice show that IL-1α is produced by microglia-like cells after ischemic brain injury, which contributes to the inflammation (Luheshi <i>et al.</i>).

Descrição: Interleukin 1 beta (IL-1β) is synthesized as an inactive precursor protein or pro-IL-1β. This precursor is cleaved intracellularly by caspase 1 (IL-1β convertase) to form the active form of the protein that is later secreted (Allan <i>et al.</i>). IL-1β binds to IL-1 receptor and activates intracellular signaling via the MAPK or NF-κB pathway. IL-1β is released by monocytes, tissue macrophages, and dendritic cells in response to infection or injury and induces expression of acute-phase proteins. It also promotes the infiltration of inflammatory and immunocompetent cells from the circulation into the extravascular space and affected tissues, by stimulating the expression of adhesion molecules on endothelial cells. IL-1β also affects other immune cells; for example, it co-stimulates T cell functions together with an antigen or mitogen. It also stimulates Th17 differentiation and B cell proliferation in an IL-6-dependent manner.

Descrição: Lipocalin-2 (LCN2) is a member of the lipocalin superfamily, which share a highly conserved fold containing an eight-stranded antiparallel beta barrel (Flower), and transport small hydrophobic molecules. Playing a role in innate immunity, Lipocalin-2 acts as a potent bacteriostatic reagent by sequestering iron-containing siderophores (Flo <i>et al.</i>). It is mainly expressed in activated neutrophils, but is also secreted by other immune cells in response to infection. Lipocalin-2 has been implicated in multiple cellular processes, such as differentiation (Yang <i>et al.</i>), migration (Du <i>et al.</i>), and apoptosis (Devireddy <i>et al.</i>). <i>In vitro</i> studies suggest that lipocalin-2 is a potential therapeutic target for certain cancers, including colorectal cancer (CRC; Zhang <i>et al.</i>) and chronic lymphocytic leukemia (Bauvois <i>et al.</i>). This protein product contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, lipocalin-2 from STEMCELL comes lyophilised with ≥94% purity, and endotoxin levels are verified to be ≤1.0 EU/μg protein.

Descrição: A member of the pentraxin family of proteins, C-reactive protein (CRP) plays important roles in host defenses, including regulating complement activation in vivo (Sjoberg <i>et al.</i>), decreasing nitric oxide production, and inhibiting angiogenesis in vitro (Verma <i>et al.</i>, 2002). At specific concentrations, CRP directly inhibits endothelial progenitor cell (EPC) differentiation, survival, and function, and is thus implicated in the development of cardiovascular diseases (Verma <i>et al.</i>, 2004). CRP is primarily synthesized by liver hepatocytes, but also by other immune cells, such as macrophages and lymphocytes (Sproston and Ashworth). The expression of this acute-phase protein is induced by IL-6 and IL-1 secretion of macrophages and T-cells during inflammation. For consistency and reproducibility across your applications, C-reactive protein from STEMCELL comes lyophilised with ≥87% purity, and endotoxin levels are verified to be ≤1,0 EU/μg protein.

Descrição: Vascular endothelial growth factor D (VEGF-D) is a member of the VEGF/platelet-derived growth factor (PDGF) family of proteins. VEGF-D is a potent angiogenic factor and promotes lymphangiogenesis, endothelial cell growth and survival, and can affect blood vessel permeability. VEGF-D is expressed in the lung, heart, small intestine, fetal lung, and at lower levels in the pancreas, colon, and skeletal muscle (Otrock <i>et al.</i>; Roy <i>et al.</i>; Stacker <i>et al.</i>; Yamada <i>et al.</i>). VEGF-D is a ligand for VEGF receptors 2 (Flk1) and 3 (Flt4) (Baldwin <i>et al.</i>). VEFGR-3 is highly expressed in lymphatic endothelial cells and is essential for their growth and differentiation (Otrock <i>et al.</i>; Roy <i>et al.</i>). Binding of VEGF-D to neuropilins contributes to VEGFR-3 signaling during lymphangiogenesis, whereas binding to integrin α9β1 promotes endothelial cell adhesion and migration (Roy <i>et al.</i>; Otrock <i>et al.</i>). During embryogenesis, VEGF-D also plays a role in the formation of the venous and lymphatic systems.

Descrição: Heparin-binding epidermal growth factor (EGF)-like growth factor (HBEGF) is a member of the EGF family (Nishi and Klagsbrun). HBEGF promotes blastocyst adhesion to the uterine wall (Iwamoto and Mekada). It also plays a role in smooth muscle cell hyperplasia and brain injury (Nishi and Klagsburn). HBEGF produced by CD4+ T cells promotes wound healing by stimulating migration and proliferation of keratinocytes, fibroblasts, and smooth muscle cells (Blotnick <i>et al.</i>). It binds to EGFR, ErbB4, ErbB2, and ErbB3, activating the PI3K/AKT signaling cascade (Iwamoto and Mekada). HBEGF is produced in a variety of cells, where it contributes to physiological and pathological processes. HBEGF is overexpressed in ovarian, breast, gastric, colorectal, pancreatic, and endometrial cancers, which likely contributes to pathogenesis (Miyata <i>et al.</i>). This product is animal component-free.
