New imaging methods and tools to study vascular biology

• Purpose of review Throughout history, development of novel microscopy techniques has been of fundamental importance to advance the vascular biology field. This review offers a concise summary of the most recently developed imaging techniques and discusses how they can be applied to vascular biology. In addition, we reflect upon the most important fluorescent reporters for vascular research that are currently available. Recent findings Recent advances in light sheet-based imaging techniques now offer the ability to live image the vascular system in whole organs or even in whole animals during development and in pathological conditions with a satisfactory spatial and temporal resolution. Conversely, super resolution microscopy now allows studying cellular processes at a near-molecular resolution. Summary Major recent improvements in a number of imaging techniques now allow study of vascular biology in ways that could not be considered previously. Researchers now have well-developed tools to specifically examine the dynamic nature of vascular development during angiogenic sprouting, remodeling and regression as well as the vascular responses in disease situations in vivo. In addition, open questions in endothelial and lymphatic cell biology that require subcellular resolution such as actin dynamics, junctional complex formation and stability, vascular permeability and receptor trafficking can now be approached with high resolution.
