It consists of plasma cells and/or plasmablasts that migrate to the red pulp from the white pulp (lymphoid follicles, germinal centers) following acute or chronic antigen-specific stimulation ( Figure 1 and Figure 2 , arrows), where they secrete large volumes of antibodies. Small foci of plasma cells that blend in with normal splenic cellular constituents frequently occur in spleens of aged rats and mice. If needed, plasma cells can be identified with immunohistochemistry for human kappa light chains or immunoglobulins. ## 英文原文 · Recommendation Plasma cell hyperplasia should be diagnosed when the number of plasma cells exceeds that seen in concurrent controls. When diagnosed, it should be graded. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0436.jpg - https://www.labsmart.cn/ntp-atlas-images/ntp_0438.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
