The goal of our studies is to determine the role of neural stem cells in development, regeneration, and tumor formation in the cerebellum. By understanding the role of stem cells, we hope to learn to use them for repair of neurological damage and to develop more effective treatments for patients with brain tumors.
We have made significant progress towards our goals during the past year. We have identified new drugs that potently inhibit the growth of medulloblastoma, the most common malignant brain tumor in children. This work could lead to development of new, more effective therapies for medulloblastoma in patients. In addition, we have developed new models for several types of brain tumors, including one that resembles the most aggressive form of medulloblastoma, and several that model choroid plexus tumors. These models are valuable resources for studying the biology and therapeutic responsiveness of these diseases. Over the next few years, we will continue in our efforts to develop more effective therapies for children suffering from aggressive brain tumors.
