Fibroblast growth factor 9 (FGF-9) belongs to the fibroblast growth factor (FGF) family. Members of the FGF family have a broad range of mitogenic and cell survival activities and are involved in various biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth, and invasion. FGF-9 plays a crucial role in regulating embryonic development, cell proliferation, cell differentiation, and cell migration. Additionally, FGF-9 may be involved in the growth and differentiation of glial cells during development, glial proliferation during brain tissue repair and regeneration after injury, differentiation and survival of neuronal cells, and stimulation of the growth of gliomas. Recombinant Human FGF-9 is expressed by E.coli, and is produced with raw materials of pharmaceutical applicable level. The host protein residue, nucleic acid residue and common pathogens are strictly controlled, and the production and quality management procedures of the product comply with GMP regulations to ensure the traceability of the production process and all raw materials.

GM-CSF stimulates the colony formation of neutrophils and macrophages in vitro and serves for promoting the proliferation and development of early erythroid megakaryocytes and eosinophil progenitor cells. It is one of the earliest cytokines discovered to have an effect on dendritic cells (DCs). During the culture of DC, GM-CSF can promote the differentiation of monocytes into large macrophage cells, as well as the expression of MHC class II molecules on the cell surface, thus enhancing the antigen presentation function of cells. Also, GM-CSF promotes the survival of DCs. GM-CSF can activate the immune response in a variety of tumor models. The antitumor activity of GM-CSF comes from its biological function of activating macrophages and DCs. Early studies showed that CD4+ and CD8+ T cells are involved in anti-tumor immunity activated by GM-CSF. Recent studies have shown that NKT plays an important role in the antitumor activity involving GM-CSF. Recombinant Human GM-CSF is expressed by mammalian cells, and is produced with raw materials of pharmaceutical applicable level. The host protein residue, nucleic acid residue and common pathogens are strictly controlled, and the production and quality management procedures of the product comply with GMP regulations to ensure the traceability of the production process and all raw materials.

IL-1 alpha, also known as IL-1F1, upregulates the expression of IL-2R on the surface of peripheral blood lymphocytes. When IL-1 alpha is used in combination with IFN-gamma and CD3 monoclonal antibody, the cytotoxicity of CIK can be significantly increased. IL-1 alpha stimulates the proliferation of CD4+ T cells in vitro, induces the production of IL-2, co-stimulates CD8+/IL1R+ T cell activation, and stimulates mature B cell proliferation and immunoglobulin secretion. Recombinant Human IL-1 alpha is expressed by E. coli, and is produced with raw materials of pharmaceutical applicable level. The host protein residue, nucleic acid residue and common pathogens are strictly controlled, and the production and quality management procedures of the product comply with GMP regulations to ensure the traceability of the production process and all raw materials.
