该方案详细描述了从正常供体的外周血细胞中获得相当数量的人肥大细胞而不使用干细胞动员处理的方法。通过使用磁性细胞分选系统,当从健康供体抽取100 ml血液时,在CD 34(+)级分中回收10(4)-10(5)个细胞。当这些细胞使用添加有干细胞因子和白细胞介素6的甲基纤维素培养基培养时,6周内形成10(3)-10(4)个肥大细胞集落。培养6周时的肥大细胞总数为10(6)-10(7)。
This protocol details a method for obtaining a considerable number of human mast cells from peripheral blood cells from normal donors without using stem cell mobilization treatment. By using the magnetic cell sorting system, 10(4)-10(5) cells are retrieved in the CD34(+) fraction when 100 ml of blood is drawn from a healthy donor. When these cells are cultured using methylcellulose medium supplemented with stem cell factor and interleukin 6, 10(3)-10(4) mast cell colonies are formed in 6 weeks. The total mast cell number at 6 weeks of culture will be 10(6)-10(7).
