Separation of Megakaryocytes From Mouse Bone Marrow by Velocity Sedimentation

A. Nakeff and B. Maat


A technique for separating mouse bone marrow megakaryocytes by unit gravity velocity sedimentation is described using a modified sedimentation chamber. The velocity sedimentation profile for megakaryocytes comprises three peaks corresponding to sedimentation velocities of 30, 60, and 100 mm/hr. Morphologic examination of megakaryocytes in the 30 mm/hr peak reveals them to be primarily immature with the latter two peaks corresponding to larger, more mature megakaryocytes.
