- Description
- Description: This 2A9-1 monoclonal antibody reacts with human CX3CR1, which is the receptor for fractalkine, a transmembrane chemokine of the CX3C family. CX3CR1 is a seven transmembrane G protein-coupled receptor expressed on CD16+ NK cells, T cells (e.g. CD8+, CD4+, and gamma/delta), and monocytes. In non-immune cells, CX3CR1 has been found on osteoclast precursors and microglia. Little to no CX3CR1 surface expression can be detected on B cells and granulocytes. Together, fractalkine and its receptor mediate cell-cell adhesion and chemotaxis of NK cells, T cells, and monocytes. The expression of CX3CR1 has also been correlated with high levels of intracellular perforin and granzyme B. Applications Reported: This 2A9-1 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 2A9-1 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Filtration: 0.2 µm post-manufacturing filtered.

Samples were subsequently stained intracellularly with Anti-Human Perforin FITC (Product # 11-9994-42). Cells were gated on CD16+CD56+ using Anti-Human CD16 eFluor® 450 (Product # 48-0168-42) and Anti-Human CD56 APC.

- Figure 2. Microglia-like cells (ScMglia) differentiated from hPSC develop microglia-like morphology and express microglia/myeloid markers. (a, b) Representative images (taken with 4 x objective) of cystic (a) and dense, noncystic (b) EBs in culture at Day 10. (c) Representative phase contrast images at 10 x of differentiating cells at Day 21 and (d) magnified 32 x images of microglial-like precursor cells at Day 21 exhibiting rounded morphologies with microglia-like processes (red box inset in (c)). (e) Phase image (32 x objective) of microglia-like cells (ScMglia) differentiated from iPS cells at Day 28, showing ramified morphology and even spacing among cells that have migrated away from the EB. (f) Most cells with this morphology also stained positively for microglial marker Iba1 (red). (g) Phase imaging showing fewer ScMglia were observed after extended culture (8 to 10 days after P1 plating) and (h) Iba1 immunolabeling demonstrates iPS-derived microglia-like cells continued to be Iba1 immunoreactive. Some microglia-like cells began to exhibit a more rounded morphology. (i) Representative flow cytometry analysis of ScMglia derived from an iPSC line showing 20.02% of gated cells express TREM2 (the M1 population); a total of 4,924 cells (events) were counted. (j) Flow cytometry analysis of ScMglia derived from both iPS and ES cells demonstrates both ES and iPSC-derived microglia-like cells express CX3CR1. (k) Differentiated ScMglia show double immunolabeling for CD11b and C

- Fig. 4 oMG expressed microglia-characteristic cell surface markers and showed similar functional immune and phagocytic properties as adult MG. a Flow cytometric analyses of the expression pattern of microglial extracellular markers on CD11b+-gated oMG (oMG 1, 3, and 5) compared to adult MG derived from three separate brain regions from adult MG1.1. (eight organoids were pooled per donor (oMG 1, 3, and 5) after 52 days in culture). b Morphology of magnetic automated cell sorted CD11b+ oMG 1 and adult MG in bright field microscope after 1 week in culture. Scale bar 40 mum. c mRNA expression, determined by qRT-PCR, of pro-inflammatory cytokines IL6 and IL1B after 6 h stimulation with LPS was significantly higher in oMG compared to adult MG (Mann-Whitney test IL6 and IL1B: U = 0, n = 4, p = 0.03). LPS-stimulated response relative to control condition without LPS. ( n = 4 experiments, eight organoids pooled per experiment; adult MG1.1) (* p < 0.05). d Anti-inflammatory response of oMG and adult MG was compared by qRT-PCR for expression of anti-inflammatory genes CD163 and MRC1 upon 72 h stimulation with dexamethasone. Dexamethasone-stimulated response relative to control condition without dexamethasone. (oMG, n = 3 separate experiments in which oMG were isolated from > 4 pooled cerebral organoids from iPSC 1 per experiment; adult MG, n = 4). e Phagocytosis capacity was tested oMG 1 and adult MG by performing a phagocytosis assay with iC3b-coated green-yellow
