Imaging oxygen in neural cell and tissue models by means of anionic cell-permeable phosphorescent nanoparticles

By -
A new paper entitled "Imaging oxygen in neural cell and tissue models by means of anionic cell-permeable phosphorescent nanoparticles" just have been published by the team in CMLS journal. This is result of joint efforts of team members with Department of Anatomy and Neuroscience (UCC), Graz University of Technology (Graz, Austria) and RCSI (Dublin).
The paper describes development and application of novel multi-modal nanoparticle O2 probes intended for high-resolution imaging in diverse range of neural cell models, including 2D cultures of primary cells, multi-cellular aggregates and live brain slices. As a proof-of-concept, the multiplexed detection of O2 in relation to distribution of neural progenitor cells was performed. We hope that this probe, termed PA2 will become a potent tool for broad area of neuroscientists and scientists working in related areas.

Affordable microscopy of spheroid oxygenation (video protocol)

Our lab has published a new protocol paper, this time with the video, in the Journal of Visualized Experiments (JoVE)! In this research method paper, we report the use of red/ near-infrared emitting biocompatible nanosensors to monitor oxygenation of the live multicellular spheroids (made of one or more cell types), together with the tracers of cell death. While this methodology is typically available only for users with 'high-end' PLIM microscopes and alike, we show that using of ratiometric readout with the red and near infrared emitting fluorescent nanosensors makes this possible on broadly available 'widefield' fluorescence microscope platforms. This method helps comparing oxygenation of spheroids, assessing this in a long-term and kinetic assays, comparing their variability and viability, essential in follow-up 3D printing applications. This is the first article in our collection ' Quantitative live cell imaging of 3D models' , guest-edited together with ...

JoVE Methods collection: Quantitative live cell imaging of 3D models

Together with Prof. Margarida Barroso (Albany Medical College), we guest edit a collection of video protocols, hosted by the Journal of Visualised Experiments ( JoVE ), and  dedicated to the quantitative live cell imaging in 3D .  We expect bringing together some leaders and innovators in various aspects of the quantitative live fluorescence microscopies applied to ex vivo animal models, organoids and 3D engineered tissue blocks. The collection, which just has been started, can be assessed here .
