PG - 300-312 LID - 10.18502/ijaai.v21i3.9803 [doi] AB - Dendritic cells (DCs) are a group of bone marrow-derived cells that play a crucial role in innate and acquired immune responses. Bone marrow-derived dendritic cells (BMDC) are used in many studies, so the efficiency and purity of the differentiated cells are essential. This study aimed to investigate the effect of several parameters, including the age of mice, cell culture medium, and swirling of the culture plate, to increase the efficiency of the induced cells, considering the standard protocols. Bone marrow-derived dendritic cells were induced from both juvenile and adult mice bone marrow cells. Then, the purity of CD11c+ cells was compared between juvenile mice BMDCs and adult mice BMDCs. Cells were cultured in an enriched and non-enriched medium, and some wells were swirled when changing the medium on the 3rd day. Then the effect of enriched medium and swirling before medium replacement were evaluated based on the expression of the CD11c marker. The efficiency of DCs differentiation (CD11c+ cells) was higher when juvenile mouse bone marrow precursors were used compared to adult mice; using the enriched media with supplements and swirling the well before media replacement significantly affected the purity of immature CD11c+ cells. Due to our results, using juvenile mice, an enriched culture medium, and physical removal of granulocyte cells could significantly improve the purity and efficiency of CD11c+ cells. Therefore, considering these three items in the production protocol of these cells can probably reduce the use of lymphocyte-removing antibodies and purification methods.
