Immortalized human cells to model atrial fibrillation in vitro
Niels Harlaar is a PhD Candidate at the Laboratory of Experimental Cardiology at the Leiden University Medical Center. Here, under the supervison of prof. dr. D.A. Pijnappels and dr. A.A.F. de Vries, he focusses on the conditional immortalization of human atrial cardiomyocytes for (among many other applications) in vitro modelling of atrial fibrillation. He has successfully generated, characterized and applied this technique of these conditionally immortalized human atrial myocyte lines to model atrial fibrillation in vitro.
Niels won the Hugo van Poelgeest prize 2022 for excellent research to replace animal testing.

The NAM Navigator: A unique repository for information on the validation and acceptance of New Approach Methodologies
The NAM navigator is an innovative knowledge portal to navigate you to and through valuable information on the development, standardization, validation and acceptance of New Approach Methodologies (NAM). The NAM Navigator acts as an online guide that provides specific information needed in each of these steps, thereby increasing the broad use of animal-free innovations.

VHP4Safety project
The safety testing of chemicals and pharmaceuticals traditionally relies on animal studies. However, these raise ethical concerns and often fail to accurately predict human responses. New scientific developments offer opportunities to build a Virtual Human Platform (VHP) for safety assessment, a platform that enables assessment based solely on human physiology and biology, integrating data from in vitro and in silico models. This video explains how we are developing the VHP through an interdisciplinary approach. Read the paper in the videolink or visit or VHP4Safety (https://vhp4safety.nl/) for more information.
