The method uses planarians as an alternative in vivo model to assess carcinogenicity. Planarians are characterized by a high regenerative capacity and a large number of pluripotent stem cells. The assay is based on the discriminative power of stem cells in an in vivo setting. Based on specific stem

The chick chorioallantoic membrane (CAM) model is particularly attractive to study short-term xenografting of human ovarian tissue. Its angiogenic potential and natural immunodeficiency allow scrutiny of early follicle activation and loss and graft revascularization mechanisms. Chick embryo

UHDR irradiations show healthy tissue sparing effect known as the FLASH effect. Since 2014, the FLASH effect is investigated worldwide to understand how it works and how to trigger it. The FLASH effect is defined as an in vivo effect. However, in vivo models are often expensive and time-consuming.

Zebrafish-based platforms have recently emerged as a useful tool for toxicity testing as they combine the advantages of in vitro and in vivo methodologies. Nevertheless, the capacity to metabolically convert xenobiotics by zebrafish eleuthero embryos is supposedly low. To circumvent this concern, a

The spatiotemporal distribution of fluorescent compounds was examined during 48 h after immersion (10 µM) or microinjection (2 mg/kg) in the pericardial cavity (PC), intraperitoneally (IP) and yolk sac (IY) of 3 dpf zebrafsh eleuthero-embryos. By modelling the fluorescence of whole-body contours

Immersion treatment: zebrafish embryos at the two-cell stage were immersed in Danieau’s medium containing the compound. A compound concentration of 10 µM and DMSO concentration of 0.1% (v/v) in a volume of 5 mL was used per well (6-well-plates). At 72 h, the zebrafish medium containing the compound

Thyroid hormone system disruption (THSD) has detrimental effects on both human and environmental health. As a rising number of chemicals are reported to interfere with the thyroid hormone system, there is an increasing need for fast and reliable evaluation methods to test for THSD. Currently,

Amoebae are natural eukaryotic predators of bacteria, yeasts, fungi and they are ubiquiste. They are excellent and easy-to-use cellular infection models, as they allow to co-cultivate any organisms in a broad range of infection medium, compatible with high quality microscopy techniques,

A calculated number of bacteria is injected through the pro-legs of the larvae. As several entry points are present, this allows to inject virulent bacteria and potential antimicrobial compounds within the same host. The survival of the larvae is scored over time (days post inoculation) until about

The Galleria mellonella assay makes use of larvae of the Greater Wax Moth. G. mellonella larvae are injected with a small amount of microorganisms, and survival can easily be followed for up to 1 week. This allows to compare virulence between different organisms. Alternatively, after injection of
