The Chick Chorioallantoic Membrane: A Model of Molecular, Structural, and Functional Adaptation to Transepithelial Ion Transport and Barrier Function during Embryonic Development
Figure 4
(a) A CC cell shows its typical cytoplasmic lateral projections which separate the shell membrane (sm) from the capillaries of the blood sinus (bs). Original magnification: 11,200x; scale bar: 2 m. (b) Apical pits are formed by CC cell membrane adjacent to the inner shell membrane (sm). Original magnification: 70,000x; scale bar: 0.5 m. (c) Basal cells (BC), mitochondria-rich cells (MRC), and granule-rich cells (GRC) characterize the CAM allantoic epithelium which faces the allantoic cavity (AC). Original magnification: 21,700x; scale bar: 1 m. M. G. Gabrielli, unpublished.
