The response of sublingual epithelial cells to house dust mite allergen and potential tolerance-promoting adjuvants such as Toll-like receptor (TLR) ligands and calcitriol was investigated using primary sublingual epithelial cells isolated from dogs and cultured in vitro. After 24-h incubation with

The method is described in detail in OECD TG 439 as SkinEthicTM RHE and provides an in vitro procedure that may be used for the hazard identification of irritant chemicals (substances and mixtures) in accordance with the United Nations Globally Harmonized System of Classification and Labelling (UN

We used a 7-stage protocol to generate beta cells from human Induced Pluripotent Stem Cells (iPSC) and evaluated whether these cells are responsive to the pro-inflammatory cytokines (IFNγ, IL-1β, or IFNα) that play a role in type 1 diabetes (T1D). Our data show that human iPSC-derived beta cells

The ERα CALUX transactivation assay is described in Annex 4 of the OECD TG 455. It uses the human U2OS cell line to detect estrogenic agonist and antagonist activity mediated through human estrogen receptor alpha (hERα).This test method is specifically designed to detect hERα-mediated

The method has been fully described in OECD TG 236 and is intended to determine the acute or lethal toxicity of chemicals on embryonic stages of fish (Danio rerio). Newly fertilized zebrafish eggs are exposed to the test chemical for a period of 96 hrs. Every 24 hrs. Twenty embryos (one embryo per

The Bovine Corneal Opacity and Permeability test method (BCOP) has been fully described in OECD TG 437. It is an in vitro test method that can be used to identify chemicals (substances or mixtures) as either 1) causing “serious eye damage” (category 1 of the Globally Harmonised System for the

Four validated test methods using commercially available RhCE models are included in this Test Guideline 492. Here we focus on the SkinEthic Human Corneal Epithelium (HCE) Eye Irritation Test (EIT). It is an in vitro procedure allowing the identification of chemicals (substances and mixtures) not

In order to find a solution for the center-weighted opacity reading associated with the OP-KIT opacitometer, a prototype of a laser light-based opacitometer (PLLBO) allowing better measurement of opacities was developed (Van Goethem et al., 2010; Annex 1). The technical optimization and optical

We have established organoid cultures from patient-derived ovarian cancer (OC), in particular from the most prevalent high-grade serous ovarian cancer (HGSOC). Testing multiple culture medium components identified neuregulin-1 (NRG1) as key factor in maximizing OC organoid development and growth,
