Abstract
PURPOSE Tissue disaggregation and the cell sorting technique by surface markers has played an important role in isolating lymphatic endothelial cells (LECs) from lymphatic malformation (LM). However, this technique may have the drawback of impurities or result in isolation failure because it is dependent on surface marker expressions, the heterogeneity of which has been found in the lymphatic system. We developed a novel method for isolating LM-LECs without using whole tissue disaggregation. METHODS Seven LM surgical specimens were collected from seven patients with LMs. LM-LECs were detached from the LM cyst wall by "lumen digestion" and irrigating the cystic cavity with trypsin, and maintained in culture. RESULTS The cells formed a monolayer with a cobblestone-like appearance. Immunohistochemistry and quantitative RT-PCR of these cells revealed high expression of lymphatic-specific genes, confirming their identity as LM-LECs. The whole-exome sequencing and PIK3CA sequencing of these cells revealed somatic mutations in PIK3CA in all cases. CONCLUSIONS We established a novel technique for isolating LM-LECs from LM tissue by "lumen digestion" without whole-tissue disaggregation. The limited incorporation of non-LM LECs in the isolate in our method could make it an important tool for investigating the heterogeneity of gene expression as well as mutations in LM-LECs.

Abstract
The microvasculature heterogeneity is a complex subject in vascular biology. The difficulty of building a dynamic and interactive view among the microenvironments, the cellular and molecular heterogeneities, and the basic aspects of the vessel formation processes make the available knowledge largely fragmented. The neovascularisation processes, termed vasculogenesis, angiogenesis, arteriogenesis, and lymphangiogenesis, are important to the formation and proper functioning of organs and tissues both in the embryo and the postnatal period. These processes are intrinsically related to microvascular cells, such as endothelial and mural cells. These cells are able to adjust their activities in response to the metabolic and physiological requirements of the tissues, by displaying a broad plasticity that results in a significant cellular and molecular heterogeneity. In this review, we intend to approach the microvasculature heterogeneity in an integrated view considering the diversity of neovascularisation processes and the cellular and molecular heterogeneity that contribute to microcirculatory homeostasis. For that, we will cover their interactions in the different blood-organ barriers and discuss how they cooperate in an integrated regulatory network that is controlled by specific molecular signatures.

Abstract
Lymphangiogenesis and increased expression of lymphangiogenic growth factors are associated with high rates of lymph node (LN) metastasis and with poor prognosis in some, but not all, solid tumors. In addition to its involvement in metastasis, lymphangiogenesis has been shown to have other roles in tumor pathogenesis, such as the niche function of tumor stem cells and regulatory functions of antitumor immune responses. In contrast, evidence has accumulated that tumor-induced lymphangiogenesis displays the heterogeneity in gene signature, structure, cellular origins and functional plasticity. This review summarizes the advances in the research on the heterogeneity of tumor lymphangiogenesis and discusses how it may contribute to functional complexity and multiplicity of lymphangiogenesis in tumor progression.

Abstract
In this study, we modeled lymphangiogenesis and vascular angiogenesis in a microdevice using a tissue engineering approach. Lymphatic vessels (LV) and blood vessels (BV) were fabricated by sacrificial molding with seeding human lymphatic endothelial cells and human umbilical vein endothelial cells into molded microchannels (600 μm diameter). During subsequent perfusion culture, lymphangiogenesis and vascular angiogenesis were induced by addition of phorbol 12-myristate 13-acetate (PMA) and VEGF-C or VEGF-A characterized by podoplanin and Prox-1 expression. The lymphatic capillaries formed button-like junctions treated with dexamethasone. To test the potential for screening anti-angiogenic (vascular and lymphatic) factors, antagonists of VEGF were introduced. We found that an inhibitor of VEGF-R3 did not completely suppress lymphatic angiogenesis with BVs present, although lymphatic angiogenesis was selectively prevented by addition of a VEGF-R3 inhibitor without BVs. To probe the mechanism of action, we focus on matrix metalloproteinase (MMP) secretion by vascular endothelial cells and lymphatic endothelial cells under monoculture or co-culture conditions. We found that vascular angiogenesis facilitated lymphangiogenesis via remodeling of the local microenvironment by the increased secretion of MMP, mainly by endothelial cells. Applications of this model include a drug screening assay for corneal disease and models for tumorigenesis including lymphatic angiogenesis and vascular angiogenesis.

Abstract
BACKGROUND Relatively few attempts have been made to set up an assay that allows the measurement of lymphatic endothelial cells (LECs) motility. Nowadays, the most widely used methods involve adaptation of the Boyden chamber method or the wound scratch assay, both of them showing some limitations due to long and expensive setup and high variability. METHODS AND RESULTS We propose a new, economic, and easy to setup LEC Motility (ELM) assay that will contribute to the study of lymphangiogenesis. The experimental setup consists of extending the coating of the flask with extracellular matrix (ECM) proteins also at the area opposite to the cap, where the LECs will be initially seeded at various densities. The day after, the flasks will be inclined at an angle of about 20° to cover the entire coated surface. Twenty-four hours later, flasks will be moved to the standard position, and the motility of the cells will be easily observed. Using the ELM assay, we were able to compare the motility rate of LECs isolated from different origins, or seeded on different substrates. CONCLUSION We propose the use of a new method to evaluate the motility of LECs: the ELM assay. This cost-effective analysis has several advantages: It can be easily set up in any cell biology laboratory, can be carried out rapidly, and allows the monitoring of cellular motility for a long period.

Abstract
The principal function of the lymphatic system is to transport lymph from the interstitium to the nodes and then from the nodes to the blood. In doing so lymphatics play important roles in fluid homeostasis, macromolecular/antigen transport and immune cell trafficking. To better understand the genes that contribute to their unique physiology, we compared the transcriptional profile of muscular lymphatics (prenodal mesenteric microlymphatics and large, postnodal thoracic duct) to axillary and mesenteric arteries and veins isolated from rats. Clustering of the differentially expressed genes demonstrated that the lymph versus blood vessel differences were more profound than between blood vessels, particularly the microvessels. Gene ontology functional category analysis indicated that microlymphatics were enriched in antigen processing/presentation, IgE receptor signaling, catabolic processes, translation and ribosome; while they were diminished in oxygen transport, regulation of cell proliferation, glycolysis and inhibition of adenylate cyclase activity by G-proteins. We evaluated the differentially expressed microarray genes/products by qPCR and/or immunofluorescence. Immunofluorescence documented that multiple MHC class II antigen presentation proteins were highly expressed by an antigen-presenting cell (APC) type found resident within the lymphatic wall. These APCs also expressed CD86, a co-stimulatory protein necessary for T-cell activation. We evaluated the distribution and phenotype of APCs within the pre and postnodal lymphatic network. This study documents a novel population of APCs resident within the walls of muscular, prenodal lymphatics that indicates novel roles in antigen sampling and immune responses. In conclusion, these prenodal lymphatics exhibit a unique profile that distinguishes them from blood vessels and highlights the role of the lymphatic system as an immunovascular system linking the parenchymal interstitium, lymph nodes and the blood.

Abstract
The generation of new lymphatic vessels through lymphangiogenesis and the remodelling of existing lymphatics are thought to be important steps in cancer metastasis. The past decade has been exciting in terms of research into the molecular and cellular biology of lymphatic vessels in cancer, and it has been shown that the molecular control of tumour lymphangiogenesis has similarities to that of tumour angiogenesis. Nevertheless, there are significant mechanistic differences between these biological processes. We are now developing a greater understanding of the specific roles of distinct lymphatic vessel subtypes in cancer, and this provides opportunities to improve diagnostic and therapeutic approaches that aim to restrict the progression of cancer.

Abstract
We examined the immunohistochemical properties of selective lymph vessel markers such as LYVE-1, podoplanin, Prox-1, and VEGF R3, as well as NO synthase (NOS) and cyclo-oxygenase (COX) in two kinds of human lymphatic endothelial cell isolated from collecting and initial lymph vessels. The constitutively expressed genes in the two kinds of lymphatic endothelial cell were also evaluated using oligonucleotide microarray analysis and RT-PCR. We also investigated the effects of the oxygen concentration in culture conditions on the proliferative activities of the two kinds of human lymphatic endothelial cell. Immunoreactivity to LYVE-1 and the RT-PCR expression level of LYVE-1 mRNA in endothelial cells of initial lymph vessels were stronger than those of collecting lymph vessels. Immunoreactivity to ecNOS, iNOS, COX1, and COX2 was also found to be significantly higher than in collecting lymph vessels. In contrast, an increase in the O2 concentration ranging from 5% to 21% caused a significant reduction in the proliferative activity of endothelial cells in collecting lymph vessels. In conclusion, these findings suggest that there exists a marked heterogeneity in the immunohistochemical, genomic, and proliferative activity of human lymphatic endothelial cells between initial and collecting lymph vessels.

Abstract
Lymphangiogenesis is a highly regulated process that involves the reprogramming of venous endothelial cells into early lymphatic endothelial cells. This reprogramming not only displays a polarized expression pattern from the cardinal vein, but also demonstrates vascular specificity; early lymphatics only develop from the cardinal vein and not the related dorsal aorta. In our transgenic model of lymphangiogenesis, we demonstrate that Prox1 overexpression has the ability to reprogram venous endothelium but not early arterial endothelial cells in vivo, in spite of the fact that Prox1 expression is forced onto both vascular beds. Our observations suggest that this specificity during embryogenesis may be due to cell-cell interactions between the developing arterial endothelial cells and smooth muscle cells. These conclusions have far reaching implications on how we understand the vascular specificity of lymphangiogenesis.

Abstract
It is widely accepted that macrophages and other inflammatory cells support tumor progression and metastasis. During early stages of neoplastic development, tumor-infiltrating macrophages (TAMs) mount an immune response against transformed cells. Frequently, however, cancer cells escape the immune surveillance, an event that is accompanied by macrophage transition from an anti-tumor to a pro-tumorigenic type. The latter is characterized by high expression of factors that activate endothelial cells, suppress immune response, degrade extracellular matrix, and promote tumor growth. Cumulatively, these products of TAMs promote tumor expansion and growth of both blood and lymphatic vessels that facilitate metastatic spread. Breast cancers and other epithelial malignancies induce the formation of new lymphatic vessels (i.e., lymphangiogenesis) that leads to lymphatic and subsequently, to distant metastasis. Both experimental and clinical studies have shown that TAMs significantly promote tumor lymphangiogenesis through paracrine and cell autonomous modes. The paracrine effect consists of the expression of a variety of pro-lymphangiogenic factors that activate the preexisting lymphatic vessels. The evidence for cell-autonomous contribution is based on the observed tumor mobilization of macrophage-derived lymphatic endothelial cell progenitors (M-LECP) that integrate into lymphatic vessels prior to sprouting. This review will summarize the current knowledge of macrophage-dependent growth of new lymphatic vessels with specific emphasis on an emerging role of macrophages as lymphatic endothelial cell progenitors (M-LECP).

Abstract
Progressive renal diseases are characterized by tubulointerstitial inflammatory cell recruitment, tubular atrophy and fibrosis. Various aspects of the recruitment of leukocytes have been extensively studied, but the exit routes (i.e. the lymphatic vessels and their biology) have only recently found attention. Similar to the recruitment of inflammatory cells, the exit is coordinated by an orchestrated interaction of chemotactic cytokines and adhesion molecules. During inflammatory injury, new routes are created by the de novo formation of lymphatic vessels, i.e. neolymphangiogenesis. These newly formed lymphatic vessels help to cope with the increase in interstitial fluid related to inflammation. Here, we review some aspects of lymphatic biology and the current knowledge about lymphatic vessels in renal inflammation.

Abstract
The lymphatic system is essential for the maintenance of tissue fluid balance, immune surveillance and the absorption of fatty acids in the gastrointestinal tract. The lymphatic circulation is also a key player in disease processes such as cancer metastasis, lymphedema and various inflammatory disorders. With the identification of specific growth factors for lymphatic endothelial cells and markers that distinguish blood and lymphatic vessels, as well as the development of in vivo imaging technologies that provide new tools to examine the lymphatic drainage function in real time, many advancements have been made in lymphatic vascular research during the past few years. Despite these significant achievements, our understanding of the role of lymphatics in disease processes other than cancer metastasis is still rather limited. The current review will focus on the recent progress made in studies of lymphatics in inflammatory disorders.

Abstract
Endothelial cells are found in most organs and tissues in our body. Despite their apparent morphological and functional similarities, endothelial cells exhibit remarkable heterogeneity and plasticity. In a strict sense, no two endothelial cells are identical in terms of their biological, immunological, functional, metabolic, morphological, and anatomical aspects. Their heterogeneity and plasticity are now known to be dependent upon and conferred by their microenvironments, arteriovenous-lymphatic cell identity, organ-specific vascular beds, fluid dynamics, vessel sizes, anatomical locations, physiological and pathological states, and more. Although abundant evidence is available to demonstrate endothelial heterogeneity in the blood vascular system, studies of heterogeneity and plasticity of lymphatic endothelial cells are limited because of the short history of lymphatic research. Nonetheless, a growing body of exciting work has begun to discover that lymphatic endothelial cells are as heterogeneous as blood vascular endothelial cells. In this article, we discuss the heterogeneity and plasticity of lymphatic endothelial cells.

To clarify the roles of lymphatic endothelial cells (LEC) in the regulation of endothelial constitutive nitric oxide synthase (ecNOS) expression, we examined the effects of shear stress on ecNOS immunohistochemical staining and mRNA and protein expression in human LEC as well as on ATP release from these cells. Shear stress at 0.5 or 1.0 dyn/cm2 increased ecNOS immunohistochemical staining and ecNOS mRNA and protein expression in cultured LEC. The same strength of shear stress produced a significant release of ATP from the LEC. Exogenous ATP ranging in concentration from 10−9 to 10−6 M produced a significant increase in ecNOS immunohistochemical expression in a dose-dependent manner. The increase in ecNOS expression mediated by 10−6M ATP was significantly reduced by 10−5 M suramin. Suramin (10−5 M) caused a significant reduction in the shear stress-mediated increases in ecNOS immunohistochemical staining and mRNA expression. The shear stress-mediated increases in ecNOS expression were significantly reduced by 3 mM tetraethylammonium, 10−4 M apamin, 10−9 M iberiotoxin, 10−5 M 2-aminoethoxydephenyl borate, or 10−5M xestospongin C, but not 10−5 M glybenclamide or 10−5 M nifedipine. The shear stress-mediated increases in ecNOS expression were significantly potentiated by pinacidil or NS1619 in a dose-dependent manner. The immunohistochemical expression of small- (SKCa) and big-conductance (BKCa) Ca2+-activated K+ channels was confirmed on the surfaces of human LEC. These findings suggest that shear stress produces a significant release of ATP from LEC, which activates the purinergic P2X/2Y receptor, thereby facilitating ecNOS mRNA and protein expression through inositol 1,4,5-trisphosphate-mediated release of intracellular Ca2+ ions and the activation of Ca2+-activated K+ channels in LEC.

Human embryonic stem cell-derived vascular progenitor cells capable of endothelial and smooth muscle cell function. Exp Hematol 2010; 38:246-257.e1. [PMID: 20067819 DOI: 10.1016/j.exphem.2010.01.001] [Citation(s) in RCA: 65] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2009] [Revised: 12/31/2009] [Accepted: 01/04/2010] [Indexed: 01/17/2023]
Abstract
OBJECTIVE Previous studies have demonstrated development of endothelial cells (ECs) and smooth muscle cells (SMCs) as separate cell lineages derived from human embryonic stem cells (hESCs). We demonstrate CD34(+) cells isolated from differentiated hESCs function as vascular progenitor cells capable of producing both ECs and SMCs. These studies better define the developmental origin and reveal the relationship between these two cell types, as well as provide a more complete biological characterization. MATERIALS AND METHODS hESCs are cocultured on M2-10B4 stromal cells or Wnt1-expressing M2-10B4 for 13 to 15 days to generate a CD34(+) cell population. These cells are isolated using a magnetic antibody separation kit and cultured on fibronectin-coated dishes in EC medium. To induce SMC differentiation, culture medium is changed and a morphological and phenotypic change occurs within 24 to 48 hours. RESULTS CD34(+) vascular progenitor cells give rise to ECs and SMCs. The two populations express respective cell-specific transcripts and proteins, exhibit intracellular calcium in response to various agonists, and form robust tube-like structures when cocultured in Matrigel. Human umbilical vein endothelial cells cultured under SMC conditions do not exhibit a change in phenotype or genotype. Wnt1-overexpressing stromal cells produced an increased number of progenitor cells. CONCLUSIONS The ability to generate large numbers of ECs and SMCs from a single vascular progenitor cell population is promising for therapeutic use to treat a variety of diseased and ischemic conditions. The stepwise differentiation outlined here is an efficient, reproducible method with potential for large-scale cultures suitable for clinical applications.

Abstract
In this article we survey more than three centuries of observation and research into tumor-associated lymphatic vessels, and their role in the metastatic spread of cancer. This historical overview documents how questions regarding tumor lymphatics have been central to concepts about the process of metastasis, and how this has subsequently influenced the clinical treatment of cancer. In turn, we show how analysis of the efficacy of these treatments has challenged long-standing notions regarding the tumor lymphatics. Starting with the discovery of VEGFR-3 and its ligands VEGF-C and VEGF-D, we also review how the rapid developments over the last 15 years in the molecular analysis of the lymphatic system and in particular lymphangiogenesis have contributed to this debate. Finally we speculate on how apparently paradoxical bodies of evidence regarding the role of tumor lymphatics in determining patterns of metastatic spread might be reconciled.

Abstract
We examined the effects of CCL1, CCL2, CCL12 and CCL21 on the expression of adhesion molecules in cultured human lymphatic endothelial cells using immunohistochemical staining or Western blot analysis. In addition, we investigated whether the expressed adhesion molecule was able to facilitate the attachment of carcinoma cells to the lymphatic endothelial cells as an in vitro micrometastatic model. CCL2 caused a selective and significant expression of ICAM-1 on human lymphatic endothelial cells but CCL1, CCL12 and CCL21 did not. By increasing the stimulation time from 4 to 18 and 48 h, the intensity of immunoreactivity for ICAM-1 was significantly increased in a time-dependent manner up to 18 h. The ICAM-1 mRNA levels were also elevated significantly up to 18 h. The CCL2-mediated immunohistochemical expression of ICAM-1 was dose-dependently increased from 10 pg/mL to 1 ng/mL. The CCL2-mediated expression of ICAM-1 was significantly reduced by neutralization of CCL2 using a specific CCL2 antibody. The 18-h treatment with CCL2 caused a significant facilitation of in vitro attachment of MDA-MB-231 and MCF-7 cells to the lymphatic endothelial cells (LECs). The CCL2-mediated response in the attachment assay was also significantly reduced either by the neutralization of CCL2 or by additional treatment with anti-ICAM-1 antibody. Immunohistochemical expression of ICAM-1, but not E-selectin, was strongly observed around and within the metastatic region of sentinel lymph node isolated from breast cancer patients. These findings suggest that CCL2 induces selective and significant expression of ICAM-1 on cultured human lymphatic endothelial cells and then facilitates the attachment of carcinoma cells to the lymphatic endothelial cells, thus providing an in vitro micrometastatic model via the overexpression of ICAM-1.

Abstract
We examined the effects of supernatants of culture media of MDA-MB-231 and MCF-7 cells on the expression of adhesion molecules on human lymphatic endothelial cells (LECs) and evaluated whether the overexpression of adhesion molecules facilitated the attachment of carcinoma cells to LECs. The 48-h stimulation of MDA-MB-231, but not MCF-7, supernatant produced a significant expression of ICAM-1 on human LECs but little or no expression of E-selectin. Chemical treatment with dialyzed substances of <1,000 molecular weight (MW) caused a complete reduction of the supernatant-mediated response. In contrast, pretreatment with heating, digestion with protease, or chemical treatment with dialyzed substances of <500 MW produced no significant effect on the supernatant-mediated response. ATP (10(-7) M) caused overexpression of ICAM-1 on human LECs similar to that produced by the supernatant of MDA-MB-231. The ATP- and MDA-MB-231 supernatant-mediated responses were significantly reduced by treatment with 10(-6) M suramin (a purinergic P2X and P2Y receptor antagonist). In attachment assays, 10(-7) M ATP or MDA-MB-231 supernatant produced a significant increase in the attachment of carcinoma cells to human LECs. The treatment with 10(-6) M suramin caused a significant reduction of ATP- and supernatant-mediated facilitation of the attachment responses. Additional treatment with anti-ICAM-1 antibody also caused a significant reduction of ATP- and supernatant-mediated facilitation of the attachment responses. The experimental findings suggest that MDA-MB-231 may release or leak ATP, which produces the overexpression of ICAM-1 on human LECs through activation of purinergic P2X and/or P2Y receptors and then facilitates ICAM-1-mediated attachment of carcinoma cells to LECs.
