The NC3Rs has a strong track record in investing in in vitro models of human disease that replace the use of animals. We have recently partnered with the MRC, Wellcome and Innovate UK on a £15.9M funding call to develop human in vitro models of complex disease.

Looking for a more interactive way to teach experimental design for researchers? Make the @nc3rs.bsky.social's Experimental Design Assistant (EDA) part of your course! For ideas check out how Inserm designed their course, including tips for others wanting to do something similar 👇
@inserm.fr have reached approaching 1,000 researchers with a training course that uses the NC3Rs Experimental Design Assistant (EDA) to teach best practice for experimental design of in vivo studies.

Learn more in our interview with the organiser behind Parcours-EDA: nc3rs.org.uk/news/experim...
