Transcript The overall goal of this procedure is to isolate human and mice alveolar macrophages from lungs and bronchoalveolar lavage fluid and develop the method for their in vitro culture. Monocyte-derived macrophages (MDMs) generated from peripheral blood monocytes are widely used to model human macrophages for in vitro studies. However, the possible impact of different isolation methods on the resulting MDM phenotype is poorly described. Primary macrophage cultures may be derived from density gradient separated whole blood or bone marrow by culturing these isolates in the presence of specific growth factors in order to encourage the growth, expansion and differentiation of the macrophage cell type. Subsequently, the SVF cells were stained for F4/80 and CD11b and FACS analysis was performed using a flow cytometer to identify ATMs. Attach 25-G needle and inject 2 ml of the solution per mouse into the peritoneal cavity. LRSCs are usually discarded after routine donor plateletpheresis, but are an excellent source of leukocytes that can be used as an alternative source of PBMCs for research purposes. Allow inflammatory response to proceed for 4 days, then euthanize mice by rapid cervical dislocation. Lymph node: blood vessel (red), cortex and follicle (green) with CD8+ T lymphocytes (gray) in the T-cell zone and subcapsular macrophages on the edge (blue), medulla . Another factor to keep in mind is that cord blood can have very high platelet counts, which may facilitate the formation of clots.
