小鼠脾巨噬细胞

Macrophages are cells differentiated from circulating bone marrow-derived monocytes. The main function of macrophages is to remove cellular debris and destroy invading pathogens. Mouse Splenic Macrophages (MSMa) reside in the spleen and play an critical role in maintaining blood homeostasis [1]. There are three distinct populations of splenic macrophages including: red pulp macrophages, marginal zone macrophages, and marginal zone metallophillic macrophages [1, 2]. MSMa perform iron processing functions and aid in the capture of microbes and viruses in the circulatory system [1, 2]. Recent studies have shown that splenic macrophages contribute to stroke pathology and autoimmune diseases [3, 4]. MSMa are an excellent model for studying macrophage functions under normal physiological and pathological conditions.

MSMa from ScienCell Research Laboratories are isolated from adult C57BL/6 mouse spleen. MSMa are cryopreserved after purification and delivered frozen. Each vial contains > 1 x 106 cells in 1 ml volume. MSMa are characterized by immunofluorescence with antibody to F4/80. MSMa are negative for mycoplasma, bacteria, yeast, and fungi. MSMa are guaranteed to further culture in the conditions provided by ScienCell Research Laboratories; however, MSMa are not recommended for expanding or long-term cultures since the cells do not proliferate in regular culture.
