The aim of these CPD (Continuing professional development) is to follow the legal requirements for maintenance and demonstration of competence in laboratory animal science, and to facilitate the implementations of the 3R’s in routine animal work.

What we know and don't know about our favorite mouse model


Laboratory mouse is the most widely used model animal, accounting for more than 60% of total number of animals used for scientific purposes. Despite the fact that more than 400 inbred mouse strains exist, one has clearly emerged as a “gold standard” strain for biomedical research. In 1990’s, the C57BL/6 strain was selected as a suitable background strain for backcrossing the early knockout models. The privileged position of C57BL/6 mouse was strengthened after sequencing its genome as a reference in 2002, followed by establishing the embryonic stem cells for creating the genetically altered mice in this background. However, focusing on one strain only on the one hand, and neglecting the variation between the sub-strains of the C57BL/6 mice on the other hand, can seriously undermine the validity and reproducibility of basic research.

The aim of this presentation is to increase awareness about important details related to genetic background and origin of test subjects.
