The lymphatic system is crucial for efficient immune surveillance and for maintenance of a physiological pressure in the interstitial space. Even so, almost no information is available concerning the lymph drainage of the islets of Langerhans in the human pancreas. Immunohistochemical staining allowed us to distinguish lymphatic capillaries from blood capillaries. Almost no lymphatic capillarie...

Metastatic spread to regional lymph nodes is one of the earliest events of tumor cell dissemination and presents a most significant prognostic factor for predicting survival of cancer patients. Real-time in vivo imaging of the spread of tumor cells through the lymphatic system can enhance our understanding of the metastatic process. Herein, we describe the use of in vivo fluorescence microscopy...

Horses are highly susceptible to lymphedema. Knowledge of the morphological components of lymphatic collectors is therefore essential to understanding the function of the lymphatic system. A better knowledge of the lymphatic system allows the development of more effective treatments against lymphedema. The composition of hypodermal and deep lymphatic collectors was investigated with immunohisto...

The lymphatic system is important in tissue fluid balance regulation, immune cell trafficking, edema, and cancer metastasis, yet very little is known about the sequence of events that initiate and coordinate lymphangiogenesis. Here, we characterize the process of lymphatic regeneration by uniquely correlating interstitial fluid flow and lymphatic endothelial cell migration with lymphatic functi...

INTRODUCTION Obesity is a major cause of morbidity and mortality resulting in pathologic changes in virtually every organ system. Although the cardiovascular system has been a focus of intense study, the effects of obesity on the lymphatic system remain essentially unknown. The purpose of this study was to identify the pathologic consequences of diet induced obesity (DIO) on the lymphatic syste...

The molecular mechanisms that regulate the formation of the lymphatic vascular system remain poorly characterized. Whereas studies in embryonic stem (ES) cells have provided major new insights into the mechanisms of blood vessel formation, the development of lymphatic endothelium has not been previously observed. We established embryoid bodies (EBs) from murine ES cells in the presence or absen...

HNSCC that involves the skin is able to invade the dermal lymphatic system. Currently there is no way to identify patients with dermal lymphatic invasion preoperatively. The purpose of this study is to determine whether CT can predict dermal lymphatic invasion. Medical records, CT scans, and corresponding histopathologic slides were reviewed of HNSCC patients with skin resected as part of their...

Recent evidence on the association of lymphangiogenic growth factors with intralymphatic growth and metastasis of cancers (1–4) has raised hopes that lymphatic vessels could be used as an additional target for tumor therapy. Cancer cells spread within the body by direct invasion to surrounding tissues, spreading to body cavities, invasion into the blood vascular system (hematogenous metastasis)...

Lymphatic vascular system is a relatively rare focus of the modern cardiovascular research. In this context, the paper published by Greiwe et al. (2015)in this journal seems to represent a very important body of new evidence concerning the influence of different training regimens on lymphangiogenesis and lymphatic vessel densities in skeletal muscles and myocardium. The lymphatic system has imp...
