Description: Interleukin 31 (IL-31), a four-helix bundle inflammatory cytokine, belongs to the IL-6 cytokine family which includes IL-6, oncostatin M, leukemia inhibitory factor (LIF), and cardiotrophin-1 ( Dillon <i>et al.</i>). IL-31 signals through a heterodimer composed of IL-31RA (also known as gp130-like receptor or GPL) and the oncostatin-M receptor (OSMR), both of which are expressed on monocytes (Diveu <i>et al.</i>; Ghilardi <i>et al.</i>), epithelial cells (Ip <i>et al.</i>), and keratinocytes (Kato <i>et al.</i>). Signaling through the GPL/OSMR complex activates the JAK/STAT, RAS/ERK, and PI3K/AKT signaling pathways, resulting in the downstream activation of STAT1, STAT3, and STAT5 transcription factors (Cornelissen <i>et al.</i>; Dambacher <i>et al.</i>; Dillon <i>et al.</i>; Ip <i>et al.</i>). IL-31 responses have been associated with allergic responses and inflammatory skin diseases including atopic dermatitis (Cornelissen <i>et al.</i>; Gangemi <i>et al.</i>).

Description: Interleukin 19 (IL-19) is a member of the IL-10 cytokine family and is produced by keratinocytes, B cells, and monocytes (Romer <i>et al.</i>; Wolk <i>et al.</i>). Expression of IL-19 can be induced by granulocyte-macrophage colony-stimulating factor (GM-CSF) or lipopolysaccharide (LPS; Gallagher <i>et al.</i>). IL-19 is considered to be a proinflammatory cytokine, as it upregulates IL-6 and tumor necrosis factor alpha (TNF-α; Liao <i>et al.</i> 2002). IL-19 binds the IL-20 receptor complex (IL-20R) which comprises IL-20R alpha and IL-20R beta to activate the STAT3 pathway (Dumoutier <i>et al.</i>). IL-19 also induces T-helper cell differentiation towards a Th2 response, resulting in the production of IL-10 and additional IL-19 (Liao <i>et al.</i> 2002; Liao <i>et al.</i> 2004). IL-19 has been implicated in aging, vascular disease, Type I diabetes, and rheumatoid arthritis.

Description: 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.

Description: The platelet-derived growth factor (PDGF) family has five heparin-binding members that assemble into four homodimers (PDGF-AA, PDGF-BB, PDGF-CC, and PDGF-DD) and one heterodimer (PDGF-AB; Fretto <i>et al.</i>; Li and Eriksson). PDGF signals through the receptor tyrosine kinases PDGFRα and PDGFRβ. It has been shown that PDGF-induced migration involves signaling pathways involving MEK/ERK, EGFR, Src, and PI3K/AKT (Kim <i>et al.</i>). PDGF is a potent mitogen for cells of mesenchymal origin, such as fibroblasts, glial cells, and vascular smooth muscle cells. PDGF has been implicated in pathogenesis of atherosclerosis, glomerulonephritis, cancer, and in the contraction of vascular smooth muscle cells of rat aortic tissues (Fretto <i>et al.</i>; Sachinidis <i>et al.</i>). PDGF-DD promotes growth and survival of renal artery smooth muscle cells and lens epithelial cells, and can act as a macrophage chemoattractant (Changsirikulchai <i>et al.</i>; Lokker <i>et al.</i>; Ray <i>et al.</i>; Uutela <i>et al.</i>).

Description: 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.

Description: Platelet-derived growth factor (PDGF) is a dimeric glycoprotein consisting of two disulfide bridge-stabilized polypeptide chains, A and B, which are assembled as heterodimers (PDGF-AB) or homodimers (PDGF-AA and PDGF-BB) (Fretto <i>et al.</i>; Westermark and Heldin). PDGF signals through the receptor tyrosine kinases PDGFRalpha and PDGFRbeta. It has been shown that PDGF-induced migration involves signaling pathways involving MEK/ERK, EGFR, Src, and PI3K/AKT (Kim <i>et al.</i>). PDGF is a potent mitogen for cells of mesenchymal origin, such as fibroblasts, glial cells, and vascular smooth muscle cells. PDGF has been implicated in pathogenesis of atherosclerosis, glomerulonephritis, cancer, and in the contraction of vascular smooth muscle cells of rat aortic tissues (Fretto <i>et al.</i>; Sachinidis <i>et al.</i>). It has been suggested that PDGF-AA is an important autocrine regulator of vascular endothelial growth factor (VEGF) expression in non-small cell lung carcinomas (Shikada <i>et al.</i>). PDGF-AA also mediates proliferation of oligodendrocyte progenitor cells and oligodendrocyte lineage differentiation through the activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2) (Hu <i>et al.</i>). PDGF-AA is commonly used to differentiate human pluripotent stem cell (hPSC)-derived neural progenitor cells into oligodendrocyte precursor cells (Piao <i>et al.</i>).

Description: 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.

Description: Granulocyte colony-stimulating factor (G-CSF) is a member of the CSF family of glycoproteins that regulate hematopoietic cell proliferation, differentiation, and function. It is a key cytokine involved in the production of neutrophils and the stimulation of granulocyte colony formation from hematopoietic progenitor cells (Metcalf and Nicola). G-CSF causes a range of effects including a transient reduction of SDF-1 expression (Petit <i>et al.</i>), the activation of metalloproteases that cleave VCAM-1 (Levesque <i>et al.</i>), and the release of norepinephrine from the sympathetic nervous system (Katayama <i>et al.</i>), leading to the release or mobilisation of hematopoietic stem cells from the bone marrow into the periphery. The G-CSF receptor is expressed on a variety of hematopoietic cells, including myeloid-committed progenitor cells, neutrophils, granulocytes, and monocytes. In addition to hematopoietic cells, G-CSF is also expressed in cardiomyocytes, neuronal cells, mesothelial cells, and endothelial cells. Binding of G-CSF to its receptor leads to activation of the JAK/STAT, MAPK, PI3K, and AKT signal transduction pathways. This product is animal component-free.

Description: 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>).

Description: 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.
