Welcome to the Piacentino Lab!

Mission: We in the Piacentino lab empower one another to grow as scientists and humans while seeking to understand how cells in the developing embryo migrate through their environment to construct our adult organ systems. Specific projects combine chicken embryology and cell culture with rigorous live imaging, molecular biology, and biochemistry to determine how cellular lipids drive migration. We foster a community built on curiosity, compassion, inclusivity, and determination.

We’re part of the Department of Cell Biology at the Johns Hopkins University School of Medicine. Interested in joining the lab? See our Join page — or head to Meet the Lab to see who we are.
