The lymphatic system is essential for tissue regeneration and repair due to its pivotal role in resolving inflammation, immune cell surveillance, lipid transport, and maintaining tissue homeostasis. Loss of functional lymphatic vasculature is directly implicated in a variety of diseases, including lymphedema, obesity, and the progression of cardiovascular diseases. Strategies that stimulate the formation of new lymphatic vessels (lymphangiogenesis) could provide an appealing new approach to reverse the progression of these diseases. However, lymphangiogenesis is relatively understudied and stimulating therapeutic lymphangiogenesis faces challenges in precise control of lymphatic vessel formation. Biomaterial delivery systems could be used to unleash the therapeutic potential of lymphangiogenesis for a variety of tissue regenerative applications due to their ability to achieve precise spatial and temporal control of multiple therapeutics, direct tissue regeneration, and improve the survival of delivered cells. In this review, the authors begin by introducing therapeutic lymphangiogenesis as a target for tissue regeneration, then an overview of lymphatic vasculature will be presented followed by a description of the mechanisms responsible for promoting new lymphatic vessels. Importantly, this work will review and discuss current biomaterial applications for stimulating lymphangiogenesis. Finally, challenges and future directions for utilizing biomaterials for lymphangiogenic based treatments are considered.

Light sheet microscopy and preparative clearing methods that improve light penetration in 3D tissues have revolutionized imaging in biomedical research. Here we present ADAPT-3D, a streamlined 3-step approach to turn tissues optically transparent while preserving tissue architecture with the versatility to handle diverse tissue sizes and types across species. Unlike extensive lipid removal utilized by existing protocols, ADAPT-3D only partially removes lipids to preserve cell membranes, yet the non-toxic aqueous refractive indexing solution still rapidly turns tissues transparent while preserving the fluorescence of endogenous and antibody conjugated fluorophores.

: Alterations in liver vascularization play a remarkable role in liver disease development, including hepatocellular carcinoma (HCC), but remain understudied. This study evaluated the hepatic microvascular imaging method and provided high-resolution quantitative anatomical data on the characteristics and architecture of liver vasculature in wild-type (WT) mice and HCC mouse models. : C57BL/6 mice were injected with Akt/Ras or Sleeping Beauty transposon to induce HCC.

Introduction: Diagnosis and treatment of lymphedema revolve around microsurgical and supermicrosurgical techniques, and various imaging modalities are integral to these techniques. Here, we discuss both the historic and novel imaging modalities in the diagnosis, pre-operative management, intra-operative period, and post-operative analysis of lymphedema.
Areas Covered: Lymphoscintigraphy has been the gold-standard for diagnosis of lymphedema, although with poor image resolution, it has fallen out of favor.

Lymphovenous anastomosis (LVA) is an effective surgical treatment for inguinal lymphorrhea, a complication that can occur after surgery involving vessels. LVA, however, requires a suitable vein for anastomosis near the leaking lymphatic vessel, which is sometimes difficult to secure. Here we report the successful treatment of a refractory ulcer with lymphorrhea by anastomosis of a flap vein to the lymphatic vessel concerned, along with flap closure.

Ewing sarcoma (EwS) is characterized by a balanced chromosomal translocation in which a member of the FET gene family is fused with an E26 transformation specific (ETS) transcription factor: the most common fusion being EWSR1-FLI1. Traditionally, EwS includes Ewing-like tumors, Askin tumors, and peripheral primitive neuroectodermal tumors (PNET), indicative of a neuroectodermal relationship. Previously, in the absence of genetic diagnostics, extraosseous EwS could be mistaken for neuroblastoma (NB), which has become particularly clear in the history of the CHP100 cell line.
