CD34 and pulmonary emphysema: The results of flow cytometric analysis of this work indicate that phenotypically different EPC (CD45−CD309+CD117+; CD45−CD31+CD34+; CD31+CD34+CD146−) were recruited from the bone marrow to the injured lungs of mice with a combined pathology (MS and pulmonary emphysema) on the 146th experiment day (results not shown) with preservation of the pattern for 188 days.
