Lymphedema (LE) is a morbid disease characterized by chronic limb swelling and adipose deposition. Although it is clear that lymphatic injury is necessary for this pathology, the mechanisms that underlie lymphedema remain unknown. IL-6 is a known regulator of adipose homeostasis in obesity and has been shown to be increased in primary and secondary models(More)
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(More)
BACKGROUND Although lymph node transplantation has been shown to improve lymphatic function, the mechanisms regulating lymphatic vessel reconnection and functional status of lymph nodes remains poorly understood. METHODS The authors developed and used LacZ lymphatic reporter mice to examine the lineage of lymphatic vessels infiltrating transferred lymph(More)
BACKGROUND The lymphatic system is commonly injured during cancer treatment. However, despite the morbidity of these injuries, there are currently no options for replacing damaged lymphatics. The purpose of this study was to optimize methods for decellularization of murine lymph nodes (LN) and to determine if these scaffolds can be used to tissue engineer(More)
Lymphangiogenesis is the process by which new lymphatic vessels grow in response to pathologic stimuli such as wound healing, inflammation, and tumor metastasis. It is well-recognized that growth factors and cytokines regulate lymphangiogenesis by promoting or inhibiting lymphatic endothelial cell (LEC) proliferation, migration and differentiation. Our(More)
Lymphedema, a common complication of cancer treatment, is characterized by inflammation, fibrosis, and adipose deposition. We have previously shown that macrophage infiltration is increased in mouse models of lymphedema. Because macrophages are regulators of lymphangiogenesis and fibrosis, this study aimed to determine the role of these cells in lymphedema(More)
INTRODUCTION Recent advances in microsurgery such as lymphaticovenous bypass (LVB) have been shown to decrease limb volumes and improve subjective symptoms in patients with lymphedema. However, to date, it remains unknown if these procedures can reverse the pathological tissue changes associated with lymphedema. Therefore, the purpose of this study was to(More)
Although obesity is a major clinical risk factor for lymphedema, the mechanisms that regulate this effect remain unknown. Recent reports have demonstrated that obesity is associated with acquired lymphatic dysfunction. The purpose of this study was to determine how obesity-induced lymphatic dysfunction modulates the pathological effects of lymphatic injury(More)
BACKGROUND The aim of this study was to determine whether sterile inflammatory reactions can serve as a physiologic means of augmenting lymphangiogenesis in transplanted lymph nodes using a murine model. METHODS The authors used their previously reported model of lymph node transfer to study the effect of sterile inflammation on lymphatic regeneration.(More)
