Interleukin 13 (IL-13) is a type I cytokine, and signals through type I cytokine receptors to activate JAK/STAT and IRS-1/IRS-2 pathways. IL-13 is produced by T cells and innate lymphoid cells (Pulendran and Artis) and it inhibits production of pro-inflammatory cytokines, prostaglandins, and reactive oxygen and nitrogen species by monocytes and macrophages (Hershey). Unlike human B cells, IL-13 has no effect on mouse B cell development and function. IL-13 promotes eosinophil survival, activation, and recruitment, and also activates mast cells (Hershey). IL-13 regulates gastrointestinal parasite expulsion, airway hyperresponsiveness, allergic inflammation, tissue eosinophilia, goblet cell hyperplasia, intracellular parasitism, tissue remodeling, tumor cell growth, and fibrosis. IL-13 induces hypercontractility of smooth muscles by directly acting on the muscle cells as well as the enteric nerves (Wynn).

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 et al.), the activation of metalloproteases that cleave VCAM-1 (Levesque et al.), and the release of norepinephrine from the sympathetic nervous system (Katayama et al.), leading to the release or mobilization 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. Mouse G-CSF was first purified from cultures of the WEHI-3B myelomonocytic leukemia cell line as the inducer of the terminal differentiation of WEHI-3B and other myeloid leukemia cell lines (Nicola et al.). It was later cloned in monkey COS cells from a cDNA library prepared with mRNA derived from mouse fibrosarcoma NFSA cells that produce G-CSF constitutively (Tsuchiya et al.). Binding of G-CSF to its receptor leads to activation of the JAK/STAT, MAPK, PI3K, and AKT signal transduction pathways.

Fibroblast growth factor 7 (FGF-7) is a member of the FGF family, and acts exclusively through a subset of FGF receptor isoforms expressed predominantly by epithelial cells (Finch and Rubin). FGF-7 seems to act specifically on epithelial cells and stimulates proliferation, migration, and differentiation of these cells, and also participates in epithelial protection and repair both in vitro and in vivo (Finch and Rubin; Werner). In contrast, FGF-7 is produced solely by cells of mesenchymal origin, and functions as a paracrine mediator of mesenchymal-epithelial communication (Rubin et al.). FGF-7 has also been shown to supplement several wound-healing properties of bioengineered skin (Erdag et al.) and to induce autophagy in human keratinocytes (Belleudi et al.). Additionally, FGF-7 has a role in pluripotent stem cell differentiation to endodermal pancreatic-like insulin-producing cells and thymic epithelial cells (Inami et al.; Niu et al.).

Heregulin-beta 1 also known as neuregulin-1 (NRG-1) is a member of the epidermal growth factor (EGF) family of growth factors and acts as a ligand for ErbB family receptor tyrosine kinases (Britsch et al.). Heregulin/neuregulin is a family of structurally related polypeptide growth factors derived from alternatively spliced genes (NRG1, NRG2, NRG3, and NRG4). Heregulin-beta 1 plays an important role during the development of the nervous system, heart, and mammary glands (Britsch). Heregulin-beta 1 is expressed in neuronal cells, and modulates cell growth and differentiation of the cells during development and wound healing (Mei and Xiong). It has been implicated through in vivo and in vitro studies that heregulin-beta 1/ErbB signaling is crucial for multiple aspects of cardiovascular development and protects the heart from ischemic injury (Odiete et al.). Heregulin-beta 1 also promotes invasiveness and metastasis of breast cancer cells (Hutcheson et al.). It has also been shown that heregulin-beta 1 has a role in the growth and maintenance of human embryonic stem cells (Wang et al.).

Interleukin 33 (IL-33) is a pro-inflammatory cytokine from the IL-1 family. It binds to the ST2 receptor and activates NF-kB and MAPK pathways. IL-33 is expressed by epithelial cells, smooth muscle cells, and fibroblasts in various tissues and organs, as well as resting basophils, mast cells, eosinophils, natural helper cells, group 2 innate lymphoid cells, dendritic cells, and activated macrophages (Schmitz et al.; Yasuda et al.). It contributes to allergic inflammation by stimulating production of the cytokines IL-4, IL-5, and IL-13 in Th2 cells, and stimulates host defense against microbial and viral infections (Liew; Yasuda et al.). In the central nervous system, IL-33 is produced by endothelial cells and astrocytes. It induces proliferation of microglia and mediates production of pro-inflammatory cytokines (Yasuoka et al.).

Interleukin 10 (IL-10) is the founding member of the IL-10 family of class II cytokines. All of the IL-10 cytokine family members have a four-helix bundle consisting of α-helical folds. Upon binding to its receptor, IL-10 activates signaling through JAK1 and STAT3. It is produced by dendritic cells, macrophages, and CD4+ T cells, as well as mast cells, NK cells, neutrophils, and B cells, under specific stimulating conditions (Saraiva and O'Garra). IL-10 can inhibit the expression of pro-inflammatory cytokines and promote healing processes, and is important for the function of regulatory T cells. IL-10 also enhances B cell proliferation, immunoglobulin secretion, and class II MHC expression, while IL-10 produced by macrophages inhibits activation of neighboring macrophages, thus allowing a level of self-regulation (Ouyang et al.).

Sonic hedgehog (Shh) is a member of the Hedgehog family of secreted signaling proteins that has a prominent role in patterning during early mammalian development (Ho and Scott). It is expressed during early embryogenesis in a variety of tissues (Finco et al.). During patterning of the central nervous system, Shh directly acts on cells to specify neural cell fates, regulates proliferation and survival of oligodendrocytes precursors and neural crest cells and stimulates proliferation, differentiation and axon growth (Ho and Scott; Martí). Shh also regulates T cell differentiation and activation (Crompton et al.). Recombinant human Shh (C24II; rhShh) is a fully biologically active molecule.

Thrombopoietin (TPO) is a key regulator of megakaryocytopoiesis and thrombopoiesis in vitro and in vivo. TPO stimulates the proliferation and maturation of megakaryocytes and has an important role in regulating the level of circulating platelets in vivo. TPO also promotes the survival, self-renewal, and expansion of hematopoietic stem cells and primitive multilineage progenitor cells. It is commonly used with other cytokines such as stem cell factor (SCF) and Flt3/Flk-2 Ligand to promote expansion of primitive hematopoietic cells in culture (Hitchcock andamp; Kaushansky). The TPO receptor, c-Mpl, is expressed at all stages of megakaryopoiesis, from hematopoietic stem and progenitor cells to mature platelets.

Tumor necrosis factor-α (TNF-α) is a pro-inflammatory cytokine that activates NF-kB, MAPK, and PI3K/AKT pathways. Activated T cells and macrophages are the primary producers of TNF-α in response to inflammation and infectious conditions. Many other cell types have been shown to produce TNF-α, among them B cells, NK cells, mast cells, neutrophils, dendritic cells, microglia, endothelial cells, smooth muscle cells, cardiomyocytes, and fibroblasts. TNF-α has cytotoxic effects on cancer cells in vitro by stimulating anti-tumor immuno- suppressive responses. TNF-α stimulates expression of E- and P-selectins, thus facilitating adhesion of neutrophils, monocytes, and memory T cells to activated platelets and endothelial cells (Zelová and Hosek). Other effects of TNF-α include vasodilatation and edema formation.
