Longitudinal high-resolution imaging through a flexible intravital imaging window
2021
Intravital microscopy (IVM) is a powerful technique that enables imaging of internal tissues at (sub)cellular resolutions in living animals. Here, we present a silicone-based imaging window consisting of a fully flexible, suture-less design that is ideally suited for long-term, longitudinal IVM of growing tissues and tumors. Crucially, we show that this window, without any customization, is suitable for numerous anatomical locations in mice using a rapid and standardized implantation procedure. This low-cost device represents a substantial technological and performance advance that facilitates intravital imaging in diverse contexts in higher organisms, opening new avenues for in vivo imaging of soft and fragile tissues. One-sentence summaryThis study presents a versatile, fully flexible imaging window that acts as an implantable transparent second skin for small laboratory animal in vivo imaging.
