Plasma cell clock face
Webfig5: The plasma cell clock-face or cart-wheel nuclear pattern as seen in 2D sections/projections from almost any angle can be explained by the multiradial arrangement of peripherally placed clump units. Top left shows 7 such units in a circle (some of these 7 will actually derive from peripheral clumps slightly out of the plane of the diagram). Webplas·ma cell ( plaz'mă sel) An ovoid cell with an eccentric nucleus having chromatin arranged like a clock face or spokes of a wheel; the cytoplasm is strongly basophilic because of the abundant RNA in its endoplasmic reticulum; plasma cells are derived from B lymphocytes and are active in the formation of antibodies. Synonym (s): plasmacyte.
