The Origin of Alveolar Macrophages in Mouse Radiation Chimeras

Abstract

This investigation attempted to determine whether the primary source of alveolar macrophages is pulmonary or hematopoietic. We have utilized an antigenic marker to identify cells of hematopoietic origin. Mouse chimeras were produced by irradiating C57B6/AF(1) mice (900 R) and then injecting them intravenously with B10D2/AF(1) bone marrow. The donor animal… (More)
