Human B Lymphocyte Electron Micrographs

Fig. Normal B lymphocyte with surface IgM. Microvilli are flowing toward one pole of the cell, the remaining membrane being relatively smoother and moderately labeled. An intermediate B lymphocyte is seen at upper right, and a neutrophil polymorphonuclear at lower left. The latter exhibits peroxidase-containing granules; its membrane is not labeled.x 12,000

  • N, nucleus
  • Mi, mitochondria



Fig. 9. This IgM-bearing lymphocyte exhibits a more complete polar concentration of labeled microvilli. The remaining surface is poorly labeled. x 12,000.



Fig. 10. Uropod-bearing lymphocyte exhibiting a "hand-mirror profile". sIg are detected by anti-Ig antibodies on the villous processes of the posterior end of this cell (arrows). A neighboring monocyte is also labeled. x 12,000.
