RESUMO
Objective To investigate mechanism involved in the differentiation of FBL-3 cells(eryth-roleukemia cells)induced by dendritic cells(DC). Methods To cultural the FBL-3 cells together with the DC supematant of different concentration for 72 hours,then we used the Wright's staining methed to record the ma-ture monocyte cell population, the transmission electron microscope to observe the ultramicrostructure, the flow eytoraetry to detect the expression rate of the surface molecular CD14. Results The Wright's staining methed, the transmission electron microscope and the flow cytometry all presented that after being induced by the super-natant of the DC ,the FBL-3 cells can partly differentiate into monocytes,inversion monocyte consistent with the personal characteristics. And the intensity of the DC supernatant was connected with interleukin-12. Conclusion The DC supernatant can induce the FBL-3 cells into monocytoid cell, the differentiated cells correspond to monocyte in macro-appearance,uhramicrostructure and phenotype. The competence of the DC supematant are partly concerned with interleukin-12.
RESUMO
Being the common tumor forms,prostate cancer,its incidence is ascending year after year.Although surgery is the key treatment means in local prostate cancer, but the complications and mortality rate are frequently observed. Radiotherapy and chemotherapy, the traditional measures in prostate cancer treatment,are limited by the indication and relatively lower curative effect. So, needs to look for effective microinvasion treatments. As the new technique of microinvasion, high intensity focused ultrasound-HIFU, is remarkerablely noticed by people, in this paper, the mechanism,equipment, clinical effect and limitation were summarized.
