Figure 2: Cells from baby corn are varied in shape: angular, columnar, and roughly spherical in form. Within the cell, the nucleus is opaque and homogenous (A). An intact, columnar cell with the central nucleus resembles columnar respiratory cells present in BAL specimens (B). Beets stained with MGG have small spherical bodies interspersed among an amorphous, bright blue background (C). The uniform, round structures have a lighter inner core, which contrast with the thickened capsular wall. The PAP stain reveals the same round bodies, but they are opaquely black in color and the wall is not as conspicuous (D). The amorphous debris is not taken up by PAP stain.
