Defining a turnover index for the correlation of biomaterial degradation and cell basedextracellular matrix synthesis using fluorescent tagging techniques

Non-destructive protocols which can define a biomaterial’s degradation and its associated ability to support proliferation and/or promote extracellular matrix deposition will be an essential in vitro tool. In this study we investigate fluorescently tagged biomaterials, with varying rates of degradation and their ability to support cell proliferation and osteogenic differentiation. Changes in fluorescence of the biomaterials and the release of fluorescent soluble by-products were confirmed as accurate methods to quantify degradation. It was demonstrated that increasing rates of the selected biomaterials’ degradation led to a decrease in cell proliferation and concurrently an increase in osteogenic matrix production. A novel turnover index (TI), which directly describes the effect of degradation of a biomaterial on cell behavior, was calculated. Lower TIs for proliferation and high TIs for osteogenic marker production were observed on faster degrading biomaterials, indicating that these biomaterials supported an upregulation of osteogenic markers. This TI was further validated using an ex vivo chick femur model, where the faster degrading biomaterial, fibrin, led to an increased TI for mineralization within an epiphyseal defect. This in vitro tool, TI, for monitoring the effect ofbiomaterial degradation on extracellular matrix production may well act as predictor of the selected biomaterials’ performance during in vivo studies.

New poster of Sanofi Pasteur for AFSTAL congress in Nantes

The PhotonIMAGER system to follow bacterial infections in mice in a non-invasive manner

This Sanofi Pasteur (Marcy-l’Étoile, France) study describes two new mouse models to follow the kinetics of infection with Pseudomonas aeruginosa and Staphylococcus aureus in longitudinal studies. Thanks to the Photon IMAGERTM system daily evaluation of the bacterial load was possible in vivo. Using a luciferase reporter gene expressed in both bacterial strains, direct correlation between CFUs and light emission could be assessed non-invasively and without any need for euthanasia or organ excision.

Focusing on the 3Rs principles, Sanofi Pasteur will be aiming to apply these models to current and future infectiology studies.

The PhotonIMAGER system for in vivo Imaging of  near-infrared persistent luminescence nanoparticles

A new study of our collaborators introduce a new generation of in vivo activated optical nanoprobes based on chromium-doped zinc gallete (ZGO). In this study Biospace Lab’s PhotonIMAGER system was used for real-timme in vivo Imaging of biodistribution of ZGO nanoparticles and persistent luminescence imainging of a tumour-bearing mouse



       In vivo comparision of widely known QDs and ZGO nanoparticles  

Bioluminescent and fluorescent images are from 5-week old female BALB/c mice after intramuscular and systemic injection of  50 μg of either 705nm  emitting carboxyl-QDs  or ZGO nanoparticles. Shown is highly sensitive     detection of the ZGO particles in deep tissues and complete lack of autofluorescence as compared to QDs (target to background ration 186 for ZGO and 16,7 for QDs)

The PhotonIMAGER system to image bioluminescent SHOC2 knockdown tumors in mice
A new study of our collaborators discuss an attractive target of therapeutic intervention for pharmacological inhibition of ERK pathway - the MRAS-SHOC2-PP1 holoenzyme. As a part of the study Biospace Lab’s PhotonIMAGER system were used to image bioluminescent SHOC2 knockdown tumors in mice (MDA-MB-231-EcoR-Luciferase cells infected with shRNA lentiviruses)

SHOC2 knockdown inhibits tumor formation. Bioluminescent images are from the twelfth day of mice injected with the indicated MDA-MB-231 cells. Shown is the relative bioluminescent signal of the SHOC2 knockdown tumors compared to the control tumors (shSCRAM) in the same animal. Data represent the mean± SEM of at least four tumors (∗p< 0.005).

Tumor targeting is of high clinical and biological relevance, and developing molecular imaging technologies for the visualization of tumors is extremely im-portant in cancer research. Optical imaging is a very promising technology for non-invasive high throughput tumor detection and tumor burden imaging thanks to some unique properties that no other method can provide. Optical imaging is highly costeffective, rapid, easy to use and can be readily applied to studying disease processes and biology in vivo. It is suitable for imaging across wide spatial scales; ranging from cells to organ systems and it is this property which makes it a sui-table approach for cancer research studies. Here, we’ll describe some methods to overcome challenges in cancer imaging using examples. Biospace Lab would like to present to you a world of opportunities in cancer research thanks to our new generation of modular optical imagers.
