This mouse bone marrow isolation protocol outlines the detailed steps for isolating mouse bone marrow cells. Unlike whole blood, mouse bone marrow yields a diverse set of cells, including hematopoietic stem cells responsible for producing leukocytes, erythrocytes, and thrombocytes, as well as stromal cells such as endothelial cells, fibroblasts, macrophages, osteoblasts, osteoclasts, and adipocytes. This comprehensive method helps ensure the successful isolation of a diverse cell population for various research applications. Evaluation methods such as flow cytometry, ELISA, and cell culture assays can be used to analyze the isolated mouse bone marrow cells, helping provide valuable insights into hematopoiesis and stromal cell functions.
