Montage of adult rat mesenteric lymphatic and blood microvascular networks immunolabeled for PECAM expression. Positive PECAM staining serves to identify lymphatic (L) and blood microvessels, including arterioles (A), venules (V) and capillaries (c). Endothelial cell expression of PECAM along the hierarchy of the respective networks is confirmed by continuous staining from the tissue feeding and draining vessels to lymphatic and blood capillary blind-ended vessel segments (arrows). Examples of a lymphatic/blood vessel connections are indicated by the “*”. Arrowheads indicate the endothelial cell structures disconnected from the nearby microvascular network. Scale bar, 100 μm.
