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 andamp; 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.

Description: Vascular endothelial growth factor (VEGF) is a heparin-binding homodimeric glycoprotein involved in vasculogenesis and angiogenesis. VEGF binds to FLT1 (VEGFR-1) and KDR (VEGFR-2), and activates Raf/MEK/ERK and PI3K/AKT pathways (Ferrara <i>et al.</i>). VEGF exists in multiple isoforms that result from alternative splicing of VEGF mRNA in the terminal exon. Proximal splice-site selection in exon 8 results in pro-angiogenic VEGFxxx isoforms (xxx is the number of amino acids), whereas distal splice-site selection results in anti-angiogenic VEGFxxxb isoforms (Nowak <i>et al.</i>). VEGF plays an important role in neurogenesis both in vitro and in vivo (Storkebaum <i>et al.</i>). It has neurotrophic effects on neurons of the central nervous system, and it promotes growth and survival of dopaminergic neurons and astrocytes. VEGF also promotes growth and survival of vascular endothelial cells, monocyte chemotaxis, and colony formation by granulocyte-macrophage progenitor cells (Ferrara <i>et al.</i>). Various splice variants of VEGF exist, with different functions. For example, it has been shown that VEGF isoform VEGF-164(165) and not VEGF-120(121) induces inflammation, stimulates intracellular adhesion molecule (ICAM)-1 expression on endothelial cells, and induces chemotaxis of monocytes (Usui <i>et al.</i>).

Description: Noggin binds to and antagonizes bone morphogenetic protein (BMP) ligands of the transforming growth factor beta (TGF-β) family. Noggin supports maintenance of undifferentiated human embryonic stem cells cultured in mouse embryonic fibroblast (MEF)-conditioned medium (Chaturvedi <i>et al.</i>), and promotes dopaminergic differentiation of embryonic stem cells and subsequent survival of dopamine neurons (Chiba <i>et al.</i>). Noggin is essential for development of ectodermal structures including neural tube, tooth, hair follicle, and eye, as well as patterning of mesodermal somites and skeletal structures. It also influences chondrogenesis, osteogenesis, and joint formation (Krause <i>et al.</i>).

Description: The B18R protein, which is encoded by the B18R open reading frame in the Western Reserve (WR) strain of vaccinia virus, is a type I interferon (IFN)-binding protein that is known to inhibit IFN antiviral response (Colamonici <i>et al.</i>). B18R protein has been shown to exhibit neutralizing activity to type I interferon family members (Meyers <i>et al.</i>) and to protect cells from the antiviral effects of interferon (Vancová <i>et al.</i>). It was recently shown that HIV-1–dependent induction of type I IFN activity and BAFF protein levels was abrogated by the soluble B18R protein, with no effect observed on the cell viability (Gomez <i>et al.</i>). B18R protein has been reported to aid in cellular reprogramming using RNA-mediated gene delivery (Warren <i>et al.</i>; Yoshioka N <i>et al.</i>).

Description: Interleukin 7 (IL-7) is a member of the type I cytokine family that is critical for T and B cell development and survival. It is produced by non-hematopoietic cells in the thymus, lymphoid organs, and by bone marrow stromal cells (Lundström <i>et al.</i>). IL-7 binds to a receptor composed of common gamma chain and IL-7Ra (CD127) and signals through the JAK/STAT and PI3K pathways. IL-7 regulates the survival of naïve and memory CD4+ and CD8+ T cells, γδ T cells, NK T cells, innate lymphoid cells, and T regulatory cells (Carrette and Surh), and provides signals to promote survival, proliferation, and differentiation during B cell development (Clark <i>et al.</i>; Corfe and Paige).

Description: Interleukin-8 (IL-8) is a member of the CXC subfamily of chemokines and is produced by leukocytic cells (monocytes, T cells, neutrophils, and natural killer cells) and non-leukocytic somatic cells (endothelial cells, fibroblasts, and epithelial cells), with the most prominent source being monocytes and macrophages. Its production is induced by inflammatory stimuli, such as IL-1. IL-8, also known as CXCL8, activates neutrophils inducing chemotaxis, exocytosis, and the respiratory burst (Baggiolini and Clark-Lewis; Mukaida). IL-8 is considered one of the most potent neutrophil chemoattractants in inflammation and binds to two different chemokine receptors on leukocytes: the G protein-coupled receptors CXCR1 and CXCR2 (Hoffmann <i>et al.</i>; de Oliveira <i>et al.</i>). IL-8 has angiogenic effects on human intestinal microvascular endothelial cells in vitro that are mediated by CXCR2 (Heidemann <i>et al.</i>). IL-8 is reported to promote breast cancer progression by increasing cell invasion, angiogenesis, and metastasis and has been reported to be involved in regulating breast cancer stem-like cells (Singh <i>et al.</i>). IL-8 also has proangiogenic properties in inflammatory diseases of the conjunctiva, cornea, iris, retina, and orbit (Ghasemi <i>et al.</i>). It was also shown that a major T cell effector function in human newborns is IL-8 production, which has the potential to activate antimicrobial neutrophils and gamma/delta T cells (Gibbons <i>et al.</i>). A variety of human pathogens, such as HIV and Mycobacterium tuberculosis, have been shown to induce IL-8 production by monocytes and macrophages (Friedland <i>et al.</i>; Meddows-Taylor <i>et al.</i>).
