Mouse monoclonal to Galectin3. Galectin 3 is one of the more extensively studied members of this family and is a 30 kDa protein. Due to a Cterminal carbohydrate binding site, Galectin 3 is capable of binding IgE and mammalian cell surfaces only when homodimerized or homooligomerized. Galectin 3 is normally distributed in epithelia of many organs, in various inflammatory cells, including macrophages, as well as dendritic cells and Kupffer cells. The expression of this lectin is upregulated during inflammation, cell proliferation, cell differentiation and through transactivation by viral proteins.

The development of monocytic cells from human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) is of particular interest because it provides an unlimited cell source for clinical application and basic research on disease pathology. Although the methods for monocytic cell differentiation from ESCs/iPSCs using embryonic body or feeder co-culture systems have already been established, these methods depend on the use of xenogeneic materials and, therefore, have a relatively poor-reproducibility. Here, we established a robust and highly-efficient method to differentiate functional monocytic cells from ESCs/iPSCs under serum- and feeder cell-free conditions. This method produced 1.31060.3106 floating monocytes from approximately 30 clusters of ESCs/iPSCs 5C6 times per course of differentiation. Such monocytes could be differentiated into functional macrophages and dendritic cells. This method should be useful for regenerative medicine, disease-specific iPSC studies and drug discovery. Introduction Monocytic lineage cells, such as monocytes, macrophages and dendritic cells (DCs), are central to immune responses and play key roles in various pathological conditions. [1]C[2] Monocytes are the myeloid progeny of hematopoietic stem/progenitor cells [3]; they are a type of mononuclear cell circulating in the bloodstream and act as gatekeepers in innate immunity. While they replenish macrophages and DCs, monocytes themselves respond to various inflammatory stimuli by migrating into inflamed tissues, phagocytosing pathological small particles and producing proinflammatory cytokines and chemokines. Therefore, monocytes not only contribute to host defense against pathogenic microorganisms, but are from the pathogenesis of chronic sterile irritation carefully. [4] Macrophages have a home in tissue and robustly phagocytose microorganisms and mobile debris. Among the essential BAPTA/AM hallmarks of monocytic lineage cells is certainly their useful plasticity. In response BAPTA/AM to cytokines and microbial items, macrophages polarize into distinct M1 and M2 cells functionally. [5] Classically turned on M1 macrophages are induced by interferon- (IFN), while activated M2 macrophages could be alternatively.
