We have implemented the use of 3D patient-derived tumor organoids, to study metabolic (dys)functions associated with tumor development and progression, including response to anticancer therapies. These sophisticated models allow to better integrate the influence of microenvironmental conditions in

More than 3 million deaths worldwide are linked to excessive alcohol consumption. Alcohol abuse associated gut barrier dysfunction is thought to play an important role in the development of alcohol-associated liver disease. Although some aspects that contribute to this process have been elucidated,

Macrophages orchestrate reactive particle segregation, compact aggregates of immune cells and non-immune cells and promote fibrosis-surrounding granulomas.
We developed a simple 3D in-vitro model that mimics granuloma formation and categorizes granuloma-inducing inorganic particles. Macrophage

We aim to differentiate ovarian cells isolated from postmenopausal ovaries into steroidogenic theca interna cells. For this purpose, cryopreserved ovarian cortex fragments are used to isolate ovarian cells. These cells are cultured on collagen and supplemented with growth factors defined to promote

The goal of chicken embryonic spinal cord electroporation is to increase or to reduce expression levels of genes of interest in the developing spinal cord, and to assess the phenotypic consequences of these alterations on neuronal differentiation or migration. Fertilized eggs stored at 14°C are

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that

This method describes the generation of porcine testicular organoids using piglet testicular cells seeded in a testicular extracellular matrix (tECM) hydrogel. To generate the solublized tECM hydrogel, porcine immature testicular tissues (ITTs) were dissected in small fragments and decellularized in

The VITOTOX test is a bacterial genotoxicity test. The test is based on bacteria that contain the lux operon of Vibrio fischeri under transcriptional control of the mutated recN promoter, which is controlled by the bacterial SOS-system (TA 104-recN2-4 strain or Genox strain). After incubation

In silico tools are computer-assisted methodologies with a high-throughput that allow to predict the toxic potential of compounds without experimental testing. Consequently, in silico tools are time-, cost- and animal-saving in nature. The most commonly used methods are (quantitative) structure
