Proliferation and identification of the dendritic cells from the peripheral blood of patients with lung cancer / 中国肺癌杂志

ABSTRACT

<p><b>BACKGROUND</b>To culture and proliferate dendritic cells from the peripheral blood of patients with lung cancer, to observe the morphologic and phenotypic characteristics of these cells and to lay a foundation for applying dendritic cells in the biotherapy of lung cancer.</p><p><b>METHODS</b>The mononuclear cells isolated from peripheral blood of patients with lung cancer were cultured with the supplement of DCGF to generate dendritic cells. Tumor associated antigens were added into dendritic cell culture on the eighth day. The morphologic characteristics of those cells were observed with inverted or electron microscopes and the phenotypic figures were analyzed with FCM.</p><p><b>RESULTS</b>A large number of mature dendritic cells were obtained from the peripheral blood of patients with lung cancer and showed specific morphologic and phenotypic characteristics. The specific antigen expressed as follows CD80 81.8%, HLA DR 98.3%, CD86 69.8%, CD1a 19.7%, CD14 83.1%.</p><p><b>CONCLUSIONS</b>The mature dendritic cells can be obtained by culturing the peripheral blood of lung cancer patients, which lays the further foundation for clinical biotherapy of tumor.</p>
