Interleukin 17A (IL-17A) is the founding member of the family of cytokines that includes IL-17B through IL-17F. It is a potent pro-inflammatory cytokine that plays a key role in defense against pathogens. IL-17A and IL-17F signal as homodimers or heterodimers through the same receptor, and activate NF-κB, MAPK, and C/EBP pathways (Gaffen). IL-17A is produced by Th17 cells, CD8+ T cells, γ/δ T cells, natural killer (NK) T cells, B cells, innate lymphoid cells, and mesenchymal stromal cells (MSCs) (Cua and Tato; Gaffen; Mojsilović et al.). IL-17A mediates protection against extracellular pathogens, and together with IL-22 stimulates production of antimicrobial peptides. It induces granulopoiesis factors and neutrophil-specific chemokines. Together with tumor necrosis factor alpha (TNF-α), IL-17A induces a sustained neutrophil recruitment during inflammation (Cua and Tato). IL-17A receptor is expressed at particularly high levels on stromal cells, including MSCs. IL-17A increases the frequency and the average size of fibroblast colony-forming units (CFU-F), as well as the proliferation of marrow-derived MSCs. It enhances osteogenic differentiation, and inhibits adipocyte differentiation and chondrogenesis (Mojsilović et al.).

Leukemia inhibitory factor (LIF) is an interleukin 6 class cytokine that regulates a broad variety of developmental functions. After LIF binds to LIF receptor (LIFR), LIFR associates with gp130 and activates JAK/STAT and MAPK signaling (Auernhammer and Melmed; Suman et al.). LIFR activation of STAT3 is essential for maintaining the mouse embryonic stem cell phenotype (Niwa et al.). Produced by the endometrium, LIF plays an important autocrine and paracrine role in implantation by regulating proliferation, invasion, and differentiation of trophoblasts following blastocyst attachment (Auernhammer and Melmed; Suman et al.). Human LIF can be used for the maintenance of mouse embryonic stem cells, however mouse LIF cannot bind to the human receptor, thus rendering mouse LIF inactive (Dahéron et al.). LIF is produced by CD4+ and activated regulatory T cells, and promotes Foxp3 expression, while repressing Th17 lineage-specific genes (Metcalfe). LIF is also secreted by mesenchymal stromal cells, where it supports hematopoiesis and immune modulation (Nasef et al.). This product is animal component-free.

Interleukin 17A (IL-17A) is the founding member of the family of cytokines that includes Interleukin 17B through Interleukin 17F. It is a potent proinflammatory cytokine that plays a key role in defense against pathogens. IL-17A and IL-17F signal as homodimers or heterodimers through the same receptor, and activate NF-kB, MAPK, and C/EBP pathways (Gaffen). IL-17A receptor is expressed on a variety of cell types, including hematopoietic cell compartments. IL-17A is produced by T helper 17 cells, CD8+ T cells, γδ T cells, natural killer T cells, B cells, neutrophils, innate lymphoid cells and mesenchymal stromal cells (MSCs; Zenobia and amp; Hajishengallis; Mojsilovic et al.). IL-17A receptor is expressed at particularly high levels on stromal cells, including MSCs. IL-17A increases the frequency and the average size of colony-forming units-fibroblast derived from bone marrow, as well as the proliferation of bone marrow-derived MSCs. IL-17A suppresses osteogenic differentiation and bone formation of bone marrow-derived MSCs. The action of IL-17A on hematopoiesis is deeply reliant on the microenvironment and the induction of other regulators. In healthy mouse bone marrow, IL-17A stimulates myeloid and early stage erythroid progenitor cells but inhibits late stage erythroid progenitor cells (Mojsilovic et al.).

Stromal cell-derived factor 1 alpha (SDF-1α) is a member of the CXC group of chemokines that binds to the G-protein coupled receptor, CXCR4, to regulate migration, proliferation, differentiation, and survival of many cell types including hematopoietic stem cells, B cells, and T cells. It is produced by bone marrow stromal cells, osteoblasts, endothelial cells, and neuronal cells. SDF-1α was first identified as the pre-B-cell growth-stimulating factor (PBSF) in the mouse bone marrow-derived stromal cell line, PA6, in the growth of B cell precursors (Hayashi et al.). SDF-1α primarily regulates cell motility during development and adulthood, including the homing of hematopoietic stem cells and neutrophils to fetal bone marrow during ontogeny (Ara et al. 2003a) and the recruitment of endothelial progenitor cells from bone marrow during angiogenesis in adulthood (Zheng et al.). In addition to its role in hematopoiesis, the SDF-1α/CXCR4 signaling pathway is also essential for the homing of primordial germ cells to gonads (Ara et al. 2003b), the migration of granule cells in the cerebellum during neurogenesis (Zou et al.), and the migration of breast cancer cells to sites of metastasis (Muller et al.).

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 et al.; de Oliveira et al.). IL-8 has angiogenic effects on human intestinal microvascular endothelial cells in vitro that are mediated by CXCR2 (Heidemann et al.). 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 et al.). IL-8 also has proangiogenic properties in inflammatory diseases of the conjunctiva, cornea, iris, retina, and orbit (Ghasemi et al.). 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 et al.). A variety of human pathogens, such as HIV and Mycobacterium tuberculosis, have been shown to induce IL-8 production by monocytes and macrophages (Friedland et al.; Meddows-Taylor et al.).
