Mouse phenotyping with near-infrared fluorescence lymphatic imaging
نویسندگان
چکیده
We demonstrate the ability to non-invasively and quantitatively image lymphatic architecture and contractile function using dynamic near-infrared (NIR) fluorescence imaging with injection of indocyanine green in normal and transgenic mice. Unlike normal mice, which showed well defined lymphatic drainage patterns and orthograde propagation of contraction waves, we observed tortuous and mispatterned lymphatic vessels and persistent retrograde lymph flow in mice with deficiency in Prox1, a transcription factor essential for lymphatic vascular development. NIR fluorescence imaging provides a method for quantifying lymphatic function for future studies designed to discern differences in lymphatic function in murine models of human lymphatic disease.

Delineation of retroperitoneal metastatic lymph nodes in ovarian cancer with near-infrared fluorescence imaging
Lymph node metastasis occurs in early-stage and late-stage ovarian cancers. Systematic lymphadenectomy is frequently conducted in an attempt to prevent disease progression. However, this method is associated with multiple complications. Therefore, it is necessary to develop a less invasive and more sensitive method for detecting lymphatic metastasis in ovarian cancer. The aim of the present stu...
متن کاملInteractions of Indocyanine Green and Lipid in Enhancing Near-Infrared Fluorescence Properties: The Basis for Near-Infrared Imaging in Vivo
Indocyanine green (ICG) is a near-infrared (NIR) contrast agent commonly used for in vivo cardiovascular and eye imaging. For medical diagnosis, ICG is limited by its aqueous instability, concentration-dependent aggregation, and rapid degradation. To overcome these limitations, scientists have formulated ICG in various liposomes, which are spherical lipid membrane vesicles with an aqueous core....
متن کاملAutomated analysis of investigational near-infrared fluorescence lymphatic imaging in humans
ALFIA (Automated Lymphatic Function Imaging Analysis), an algorithm providing quantitative analysis of investigational near-infrared fluorescence lymphatic images, is described. Images from nine human subjects were analyzed for apparent lymphatic propagation velocities and propulsion periods using manual analysis and ALFIA. While lymphatic propulsion was more easily detected using ALFIA than wi...
متن کاملDirect visualization of changes of lymphatic function and drainage pathways in lymph node metastasis of B16F10 melanoma using near-infrared fluorescence imaging
The lymphatic system provides an initial route for cancer cell dissemination in many cancers including melanoma. However, it is largely unknown how the lymphatic system changes during tumor progression due in part to the lack of imaging techniques currently available. In this study, we non-invasively imaged changes of lymphatic function and drainage patterns using near-infrared fluorescence (NI...
