Differential isolation of eosinophils and myelin phagocytes from mouse peripheral nerves during Wallerian degeneration by uncoated and immunoglobulin-coated sheep red blood cells.
Highly purified (less than 95%) eosinophilic granulocytes and myelin phagocytosing macrophages were isolated from enzyme digested mouse peripheral nervous tissue undergoing Wallerian degeneration by sequential centrifugation on Ficoll-Hypaque together with uncoated and immunoglobulin-coated sheep red blood cells. Isolation of eosinophils is a first step for further investigation of the role of these cells during Wallerian degeneration. Myelin phagocytes were found in the Fc receptor positive cell population, while undigested myelin and Schwann cells remained in the interphase.
