Jing Wang, Xiujuan Yue
The aim of the present study was to investigate the relationship between the expression of transcription factor forkhead box C2 (FOXC2) and the clinical features of cervical cancer. A total of 66 patients with cervical cancer, 42 patients with cervical intraepithelial neoplasia (CIN) and 25 patients with cervical inflammation were enrolled. The positive expression rates and expression levels of mRNA of FOXC2, E-cadherin, N-cadherin, vascular endothelial growth factor (VEGF), stromal cell-derived factor-1 (SDF-1), Notch protein and lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1) in cervical tissues were detected using immunohistochemistry and RT-PCR...

Purpose: Corneal neovascularization, in particular lymphangiogenesis, is a limiting factor in corneal transplant survival. Novel treatment approaches focus on (selective) inhibition and regression of lymphatic vessels. Imaging clinically invisible corneal lymphatic vessels is a prerequisite for these strategies. Using a murine model, this study investigates whether corneal lymphatic vessels can be imaged using microscopic optical coherence tomography (mOCT). Methods: Corneal neovascularization was induced by intrastromal placement of 11...

Purpose: Pathologic corneal (lymph) angiogenesis is a known risk factor for immune-mediated allograft rejections after corneal transplantation. However, there is no established treatment to regress pre-existing pathological corneal blood and lymphatic vessels. This study assessed the possibility to regress both vessel types by photodynamic therapy (PDT) after intravenous (i.v.) verteporfin injection, the influence of timing of PDT after verteporfin injection, and the effect on graft survival in high-risk keratoplasty...

The recent discovery of meningeal lymphatic vessels (LVs) has raised interest in their possible involvement in neuropathological processes, yet little is known about their development or maintenance. We show here that meningeal LVs develop postnatally, appearing first around the foramina in the basal parts of the skull and spinal canal, sprouting along the blood vessels and cranial and spinal nerves to various parts of the meninges surrounding the central nervous system (CNS). VEGF-C, expressed mainly in vascular smooth muscle cells, and VEGFR3 in lymphatic endothelial cells were essential for their development, whereas VEGF-D deletion had no effect...

Lymphangioma is a benign lesion of the lymphatic vessels. It is a rare paediatric condition and it is exceptional among adults. It mainly occurs in the neck, armpit and abdomen. It rarely occurs in the breast. We report the case of a 18 year-old female patient seen in consultation for a mass in her left breast, which had evolved over the last 23 months. Management was based on surgery. The patient underwent complete tumor resection. Anatomopathological examination showed lymphangioma of the breast. Patient's evolution was favorable and the patient had a median 10 months follow-up with no recurrences identified...

INTRODUCTION: The current state-of-the-art treatment modality for hypertrophic capillary malformations (CMs), laser therapy, has a considerable rate of non-responders and recurrence. Intralesional bleomycin injections (or 'sclerotherapy') are commonly used to treat venous and lymphatic malformations with an excellent effect, but these intravascular injections are not possible in CMs due to the small diameter of the vessels. Electroporation-an electric field applied to the tissue-could increase the permeability of endothelial cells, which could theoretically facilitate targeted localised bleomycin delivery...

PURPOSE: Corneal lymphatic vessels are clinically invisible because of their thin walls and clear lymph fluid. There is no easy and established method for in vivo imaging of corneal lymphatic vessels so far. In this study, we present a novel approach to visualize corneal lymphatic vessels in vivo by injecting intrastromal fluorescein sodium. METHODS: Six- to eight-week-old female BALB/c mice were used in the mouse model of suture-induced corneal neovascularization...

PURPOSE: To relate central corneal epithelial phenotype to degree of keratopathy in a limbal stem cell deficient population. METHODS: 37 patients (67 eyes) with aniridia-associated keratopathy (AAK) underwent corneal examination including slit lamp biomicroscopy to determine the Grade of AAK, Cochet-Bonnet esthesiometry, and in vivo confocal microscopy (IVCM) to assess morphology of the central corneal epithelium and subepithelial region. RESULTS: AAK Grade ranged from 1 (limbal involvement only) to 4 (total conjunctivalisation), with progression from Grade 1 occurring after the age of 20...

Recent reports have characterized functional lymphatic vessels, which drain both fluid and immune cells from the CSF to the deep cervical lymph nodes, lining the dural sinuses in mice. If conserved in the human brain these vessels could have profound implications for neuroinflammatory and neurodegenerative diseases. We provide evidence of the presence of lymphatic vessels in human dura obtained at autopsy, at the level of the superior sagittal sinus, in 4 individuals. Immunohistochemistry for the lymphatic vessel endothelial cell marker podoplanin revealed the widespread presence of multiple structures with a distinct lumen distributed throughout the superior sagittal sinus...

Articular cartilage is commonly described as a tissue made of up to 80% water, devoid of blood vessels, nerves and lymphatics, and populated by only one cell type: at first glance, an easy tissue for clinicians to repair and for scientists to reproduce in a laboratory. Yet, chondral and osteochondral defects currently remain an open challenge in orthopedics and tissue engineering of the musculoskeletal system, without considering osteoarthritis. Why do we fail in repairing and regenerating articular cartilage? Behind its simple and homogenous appearance articular cartilage hides a heterogeneous composition, a high level of organisation and specific biomechanical properties that taken together make articular cartilage a unique material that we are not able yet to repair or reproduce with high fidelity...

Cerebrospinal fluid (CSF) has been commonly accepted to drain through arachnoid projections from the subarachnoid space to the dural venous sinuses. However, a lymphatic component to CSF outflow has long been known. Here, we utilize lymphatic-reporter mice and high-resolution stereomicroscopy to characterize the anatomical routes and dynamics of outflow of CSF. After infusion into a lateral ventricle, tracers spread into the paravascular spaces of the pia mater and cortex of the brain. Tracers also rapidly reach lymph nodes using perineural routes through foramina in the skull...

The circulatory system consists of the heart, blood vessels and lymphatic vessels, which function in parallel to provide nutrients and remove waste from the body. Vascular function depends on valves, which regulate unidirectional fluid flow against gravitational and pressure gradients. Severe valve disorders can cause mortality and some are associated with severe morbidity. Although cardiac valve defects can be treated by valve replacement surgery, no treatment is currently available for valve disorders of the veins and lymphatics...

It has long been established that the thymus plays a central role in autoimmune myasthenia gravis (MG) because of either thymoma or thymic hyperplasia of lymphoproliferative origin. In this review, we discuss thymic changes associated with thymic hyperplasia and their implications in the development of an autoimmune response against the acetylcholine receptor (AChR).The hyperplastic MG thymus displays all the characteristics of tertiary lymphoid organs (TLOs): neoangiogenic processes with high endothelial venule and lymphatic vessel development, chemokine overexpression favoring peripheral cell recruitment, and ectopic germinal center development...

New approaches in regenerative medicine and vasculogenesis have generated a demand for sufficient numbers of human endothelial cells (ECs). ECs and their progenitors (EPCs) reside on the interior surface of blood and lymphatic vessels or circulate in peripheral blood; however, their numbers are limited and they are difficult to expand after isolation. Recent advances in human induced pluripotent stem cell (hiPSC) research have opened possible avenues to generate unlimited numbers of ECs from easily accessible cell sources, such as the peripheral blood...

The molecular pathogenesis of the development of non-small cell lung carcinomas (NSCLCs) is extremely complex. Understanding the molecular basis of the development of this malignant tumor may enable the use of targeted therapy, which may result in a better treatment outome for these patients. Adenocarcinoma (AC) is the most common NSCLC subtype, equally common among smokers and non-smokers, and its pathogenesis remains unknown. The SOX18 protein is an important protein that plays a role in the development of blood and lymphatic vessels during the process of embryogenesis...

The present study aimed to assess the prognostic significance of tumor lymphangiogenesis and lymphatic vessel density (LVD) in endometrioid carcinoma of the uterine corpus. The association between LVD and various factors, including lymphatic vessel invasion (LVI), and nodal metastases, were investigated. Among 202 surgically treated cases, 19 cases with nodal metastases with the infiltration reaching the outer-half myometrium (N(+) group) were selected. The LVDs of hotspots in each case were examined at 100× magnification on D2-40 stained slides of the inner- and outer-half myometrium of the peritumoral, and control compartments...

Previous studies have shown cost effectiveness and quality-of-life benefit of pneumatic compression therapy (PCT) for lymphedema. Insurers, such as the Centers for Medicare/Medicaid (CMS), however, desire visual proof that PCT moves lymph. Near-infrared fluorescence lymphatic imaging (NIRFLI) was used to visualize lymphatic anatomy and function in four subjects with primary and cancer treatment-related lymphedema (LE) of the lower extremities before, during, and after pneumatic compression therapy (PCT). Optically transparent and windowed PCT garments allowed visualization of lymph movement during single, one-hour PCT treatment sessions...

Lymphatic vessel invasion (LVI) is promising in determining prognosis and treatment strategies, but the application of LVI as a histopathological criterion in breast cancer patients especially those of different subgroups is controversial. This research aims to evaluate the prognostic value of LVI assessed by D2-40 not only in patients with early invasive breast cancer but also in lymph node-negative, lymph node-positive, luminal A-like, luminal B-like, HER2-enriched, and triple-negative subgroups.The study cohort included 255 patients with a median follow-up of 101 months...
