Researchers are targeting a comprehensive understanding of lymphatic vessels with potential implications for improved treatment.MARCO ARRIGONI, COHERENT INC.The lymphatic system is an underinvestigated part of the vascular system. A team led by Friedemann Kiefer at the European Institute for Molecular Imaging (EIMI) at the University of Münster in Germany is aiming to change that in ongoing studies of the formation and function of lymphatic vessels in lab mice. The researchers use an arsenal of fluorescent microscopy techniques to probe these vessels and unravel the genetic control of formation, function, and repair. Multiphoton microscopy, often using triple-transgenic mice, is proving to be a critical tool in these studies because it...Read full articleRelated content from Photonics MediaARTICLESBiomedical Research, Innovation to Take Center Stage at SPIE BiOSA rapid-fire Hot Topics session featuring talks on the latest in biomedical optics, from live analysis of embryonic development to deep learning-enabled optics, will be a centerpiece at SPIE BiOS...BioPhotonics Nov/Dec 2021 IssueNeurophotonic Techniques Shed New Light on Traumatic Brain InjuryTraumatic brain injury can have catastrophic impacts on everyday functioning and quality of life.
