Genetic Networks of Endoderm Organ Development

The long-term research goal in the Zorn Lab at Cincinnati Children’s Research Foundation is to understand the molecular mechanisms controlling the development of the respiratory and digestive organs including lung, liver, pancreas and the intestine, which are derived from the embryonic endoderm.

We use frog and mouse embryos to investigate the complex genetic pathways underlying this poorly understood process of organ formation. In particular we investigate how tissue interactions and transcription factors control cell identity in the embryo. This research will help our understanding of congenital diseases in these organ systems and the ability to direct the development of stem cells to make therapeutically useful tissue. We collaborate closely with the Wells Lab and other investigators in the Endoderm Club and in the Digestive Health Center. We are also involved in developing genomic resources for Xenopus and we help maintain Xenbase: the Xenopus model organism database.

Our current research focuses on three developmental steps in the progression toward making foregut organs, endoderm specification, endoderm patterning and organ bud formation.

Postdoctoral and Graduate Students Welcome

The Zorn Lab trains graduate students who are in the Molecular and Developmental Biology Graduate Program. Potential graduate students can learn more through the Molecular and Developmental Biology Graduate Program website.
