Subcellular Microanatomy by 3D Deconvolution Brightfield Microscopy: Method and Analysis Using Human Chromatin in the Interphase Nucleus

Figure 4

The basic chromatin structural unit of the plasma cell nucleus (the “clump unit” described in the text). This is essentially an ovoid curved cone. Side views (at 90 degrees to each other) are shown on the top and a plan view is shown bottom left. An oblique angle view is shown bottom right. This shape, in the arrangement shown in Figure 5, can explain the characteristic “clock-face” appearance to plasma cells in tissue sections and cytology preparations.
