Decoding Brain Development to Heal Children

The Translational Neurobiology & Drug Discovery Lab at 91大神 Children鈥檚 in Delaware Valley examines why some children develop brain tumors and neurodevelopmental disorders. Our goal is to find new ways to treat these conditions. We look at the biological processes involved in early brain development and how genetic and molecular changes cause these processes to malfunction.

Specifically, we study the neurons in the cerebellum, the part of the brain important for movement, coordination, and behavior. By learning how cells in this area grow and connect, we gain insight into how certain brain disorders happen so we can develop better, more targeted therapies.

We drive innovation by not only studying these conditions, but we also use state-of-the-art, 3D technologies to test potential drug compounds. We have made several key advances in these areas.听

Our goal is to translate breakthrough discoveries from lab bench to patient bedside. We give hope for new treatments and a long life for kids with neurologic disease.

Understanding Brain Development

We use innovative models to study normal development of cerebellar granule cells. These specialized neurons are involved in movement and fine motor control as well as in behavior, learning, and memory.听

This reveals how disturbances contribute to conditions like pediatric brain tumors or neurodevelopmental disorders. It also provides insights to inform our search for targeted treatments.

Innovating Drug Discovery

In collaboration with engineers, we are creating a 3D platform for testing drugs more efficiently. This platform uses a cell culture system that mimics the brain鈥檚 extracellular matrix, or the network of molecules that surrounds and supports brain cells.听

This platform can be used with automated robots commonly used in drug discovery labs for high-throughput screening.

Accelerating Breakthrough Treatments

Our team collaborates with researchers from the early stages of project planning. We engage in joint pilot projects to support grant applications focused on high-throughput screening and chemical probe discovery.听

Our services include acquiring targets to developing assays, conducting pilot screens, and validating lead compounds.

Recent Research Highlights

Molecular Pathways in Cerebellar Development and Maturation

Using primary neuronal cultures, organoids and transgenic mouse models, we aim at understanding the physiological function of ion transporters in cerebellar granule cell proliferation and maturation. We also study the role they play in neurodevelopmental disorders and pediatric brain tumor development.

3D Drug Screening Platforms

In an interdisciplinary approach with materials scientists, we are developing a tunable three-dimensional cell culture platform with brain-like extracellular matrix properties that is compatible with automated high-throughput screening robotics commonly found in a drug discovery lab.

High-Throughput Drug Discovery

We operate on a collaborative model encompassing early-stage project planning with investigators and joint effort pilot projects to support multi-PI grant applications focused on high-throughput screening and chemical probe discovery. Services range from target acquisition to assay development, pilot screening, and validation of lead compounds.

How We鈥檙e Making a Difference

Innovations from our lab have worked to speed up drug discovery, open the door for testing millions of compounds, and provide new tools for early intervention. Specifically, we have:

  • Demonstrated the feasibility of 3D brain tissue made of hydrogelating beta-hairpin peptide that self-assembles, is implantable with neurons and integrates with automated high-throughput drug screening.听
  • Developed technology for automated 3D cell culture scaffolds using standard high-throughput screening liquid handling equipment commonly found in drug discovery labs.
  • Conducted a pilot screen to validate the effectiveness of the above technology.
  • Showed that different isoforms of the Na,K-ATPase (sodium-potassium pump) accessory subunits have individual, non-redundant roles in neuron maturity in the cerebellum.
  • Developed a new mouse model with cerebellar abnormalities mirroring coordination and behavioral issues seen in children with neurological disorders.
  • Validated a new imaging tracer in preclinical models that can selectively detect pediatric brain tumors with high sensitivity.
