Observe the morphological changes of cells by immunofluorescence staining
Part of the samples were digested by trypsin in each group and then collected by centrifugation. The cells were adjusted to about 1*105/ml, dripped onto the glass slide, smeared evenly, and dried at room temperature. The cells were then stained according to the immunofluorescence staining procedure and observed the morphological changes under a microscope. Then we compared the cells with normal nasal polyp tissue .
