Author Spotlight: Genetically Engineered Mouse Models and Pathological Characterization of Neurofibromatosis Type 1 Associated Tumors

Our group is focused on neurofibromatosis type one and understanding the pathology of the cancers associated with the disease, plexiform neurofibromas and malignant peripheral nerve sheath tumors. To do so, we employ several techniques, including the use of a genetically engineered mouse model, P0GGF beta three, Our lab and others studying plexiform neurofibromas and malignant peripheral nerve sheath tumors face similar challenges. Limited access to patient-derived tumor samples hinders our work.

As a result, creating and characterizing genetically engineered mouse models is crucial for ongoing research into disease mechanisms and the potential development of treatments. Identifying peripheral nerve tumors can be tricky and are often misdiagnosed as other cancers. To avoid this, we have developed a detailed protocol using histology, immunohistochemistry, and grading to accurately identify and grade these tumors.

This improves the reliability of future research studies. Our work provides a framework to investigate and validate genetically engineered mouse model derived tumors to ensure they properly mimic the human disease. We will use current genetically engineered mouse models to understand tumor microenvironment and the factors essential to tumor transformation.
