Fig. 5. Ultrastructure of dermal capillaries in the skin of transgenic (B) and
control (A) mice. The plasma membrane of endothelial cells (e) appears thinner
and more irregular in transgenic mice compared with wild-type littermates.
Several fenestrae (C, arrows) and gaps (D, arrowhead) are visible in the
plasma membrane of transgenic mouse endothelial cells. p, pericyte. Bars, 1
