Sir, The histology of psoriasis vulgaris plaques is characterized by epidermal hyperplasia with uniformly elongated rete ridges enclosing presumably enlarged dermal papillae, dilated, prominent blood vessels in the upper dermis and an inflammatory infiltrate of leucocytes. Recently, Griffiths and Barker ...
response factors back to bloodstream [12]. Lymphatic system can actively promotes tumor cells migrating to lymphatic vessels [15], meanwhile tumor-derived growth factors stimulate intratumoral and peritumoral lymphangiogenesis, facilitating lymphovascular invasion (LVI) to remodel tumor microenvironment (TME)...
Structure Lymphatic capillaries; lymphatic vessels, ducts and tracts; primary and secondary lymphoid organs, Function Fluid regulation; immune surveillance; transport of large molecules Clinical relations Cancer spreadingThis article will discuss the anatomy and functions of the lymphatic system.Contents...
Our findings indicate that lymphatic vessels are not present in the normal adult intervertebral disc but that, when there is extrusion of disc material into surrounding soft tissue, there is ingrowth of reparative fibrous tissue containing lymphatic vessels. Our findings also indicate that chordoma, a...
Cranial lymphatic vessels (LVs) are involved in transport of fluids, macromolecules and CNS immune responses. Little information about spinal LVs is available, because these delicate structures are embedded within vertebral tissues and difficult to visualize using traditional histology. Here we reveal an...
Recent studies have shown that meningeal lymphatic vessels (MLVs), which are located both dorsally and basally beneath the skull, provide a route for draining macromolecules and trafficking immune cells from the central nervous system (CNS) into cervical lymph nodes (CLNs), and thus represent a ...

Lymphatic vessels play an important role in the maintenance of tissue homeostasis1 and in the transport of immune cells,2 but they also serve as the primary conduit for malignant tumor cell metastasis to regional lymph nodes.3 Although there is considerable evidence, obtained in genetic and xenotr...
The lymphatic transport system can subdivide into five components: capillaries, collecting vessels, lymph nodes, trunks, and ducts. The initial point of entry into the lymphatic system is through the capillaries, which are a single layer of partially overlapping endothelial cells creating a valve. Th...
