GM-CSF濃度梯度對樹突狀細(xì)胞體外誘導(dǎo)培養(yǎng)的影響
[Abstract]:Aim: to observe the effects of granulocyte-macrophage colony stimulating factor (granulocyte-macrophage colonystimulating factor,GM-CSF) combined with interleukin-4 (interleukin,IL-4) on the morphology, purity and cell number of murine bone marrow-derived dendritic cells (dendritic cell,DC), and to explore the optimal conditions for the induction and culture of dendritic cells. Methods: the mouse bone marrow mononuclear cells were isolated and purified, and the morphologic and phenotypic observation and activation of allogeneic lymphocytes were performed by adding different concentration gradient GM-CSF and quantitative IL-4, respectively. Results: the number, purity and maturity of bone marrow-derived dendritic cells increased with the increase of GM-CSF concentration in a certain concentration range. Too high concentration of GM-CSF resulted in inhibitory effect. Therefore, it can be inferred that the ideal range of GM-CSF concentration should be 10-20 ng/mL.. Conclusion: the suitable concentration of GM-CSF combined with IL-4 can enhance the ability of mouse bone marrow mononuclear cells to differentiate into dendritic cells. The rational use of two kinds of cytokines can increase the number, purity and maturity of dendritic cells.
