Deciphering the Mechanisms of Developmental Disorders (DMDD) is a large-scale imaging and phenotyping programme for genetically modified mouse embryos. For embryos at E14.5, the key imaging technique is High Resolution Episcopic Microscopy (HREM), and the resulting images are used to comprehensively phenotype the embryos using a systematic approach.

With a combination of lectures, demonstrations and hands-on sessions, this three-day workshop will introduce HREM technology and discuss the value of the resulting images when used to score morphological phenotypes. The HREM procedure will be described, while sample preparation and data generation will be demonstrated.

As an introduction to phenotyping, the workshop will cover the normal anatomy of E14.5 mouse embryos and the morphology, topology and tissue architecture of their organs as presented in HREM data. A special focus will be given to developmental peculiarities and norm variations in anatomy. A protocol for scoring abnormalities will be demonstrated, after which hands-on sessions will allow participants to practice scoring both wild-type and mutant embryos whilst receiving feedback.
