LYVE‑1 was detected in immersion fixed paraffin-embedded sections of human tonsil using 15 µg/mL Goat Anti-Human LYVE‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2089) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Overview of Multi-dimensional Microscopic Molecular Profiling (MMMP).The overall MMMP approach is depicted using an example tissue section from normal human duodenum (sample #1.9.7). (a) Slides were subjected to repeated cycles of staining and imaging with fluorescent primary antibodies and DAPI. At the end of each cycle, fluorescent signal was removed by a chemical bleaching process, and slides were again imaged, before proceeding to the next round of this iterative procedure. After the final antibody stain (#15 Sma), slides were analyzed with a series of histochemical stains. (b) A set of tiling images spanning each tissue section was initially generated by the microscope system. The tiling images were then computationally ‘stitched’ together to produce a single image per staining cycle for each sample. (c) Image registration was performed to align images from the same tissue section across cycles. Mean intensities of the DAPI signal from all immuno-fluorescence images are shown from before (Unregistered) and after (Registered) the image registration procedure was completed. (d) Following registration, signal intensities from the relevant channels for each image (columns) in the MMMP series were extracted for each pixel (rows) within the tissue section and compiled into a large data matrix of in situ molecular profiles.

TGF-beta 1, -beta 2 and -beta 3 reduce lymphatic marker expression in LECs.Primary human LECs were treated with 10, 20 or 30 ng/ml TGF-beta 1, -beta 2 and -beta 3 for 72 hours (a) or 100 hours (b). Untreated cells served as a control. Lysates were prepared and analysed by Western blot using antibodies specific for Lyve-1, Prox-1, VEGFR-3 or vimentin. Vinculin served as loading control. The experiment was performed twice with equivalent results. For densitometry evaluation, protein bands were analysed using the software ImageJ. Bands for the Prox-1, Lyve-1, vimentin and VEGFR-3 proteins were normalized to the corresponding loading control and are displayed as the expression level relative to the untreated control samples.

Background: LYVE-1

Lymphatic vessel endothelial hyaluronan (HA) receptor-1 (LYVE-1) is a receptor of HA, a linear high molecular weight polymer composed of alternating units of D‑glucuronic acid and N-acetyl-D-glucosamine. HA is found in the extracellular matrix of most animal tissues and in body fluids. It modulates cell behavior and functions during tissue remodeling, development, homeostasis, and disease (1). The turnover of HA (several grams/day in humans) occurs primarily in the lymphatics and liver, the two major clearance systems that catabolize approximately 85% and 15% of HA, respectively (1-3). LYVE-1 shares 41% homology with the other known HA receptor, CD44 (4). The homology between the two proteins increases to 61% within the HA binding domain. The HA binding domain, known as the link module, is a common structural motif found in other HA binding proteins such as link protein, aggrecan and versican (1, 5). Human and mouse LYVE-1 share 69% amino acid sequence identity.

LYVE-1 is primarily expressed on both the luminal and abluminal surfaces of lymphatic vessels (4, 5). In addition, LYVE-1 is also present in normal hepatic blood sinusoidal endothelial cells (6). LYVE-1 mediates the endocytosis of HA and may transport HA from tissue to lymph by transcytosis, delivering HA to lymphatic capillaries for removal and degradation in the regional lymph nodes (5, 7, 8). Because of its restricted expression patterns, LYVE-1, along with other lymphatic proteins such as VEGF R3, podoplanin and the homeobox protein propero-related (Prox-1), constitute a set of markers useful for distinguishing between lymphatic and blood microvasculature (4, 5, 9-11).
