The long-term goal of our research is to develop new therapeutic strategies for stroke, Alzheimer's disease, CADASIL disease, and traumatic brain injury.
Our current research focuses on enhancing brain repair after brain damage by either brain disease or injury. The major approaches used for our study include molecular biology, cellular biology, microsurgery, live brain imaging, flow cytometry, motor function and cognitive function assessment, immunohistochemistry and brain section imaging.
Stroke is considered a brain attack and is ranked as the number one cause of long-term disability in adults. Alzheimer's disease (AD) is a neurodegenerative disease that causes irreversible progressive brain damage and memory loss. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a rare hereditary stroke disorder and an autosomal dominant vascular dementia. Currently, there is no drug that can improve the functional outcome for stroke nor is there a treatment that can stop or delay the progressive brain damage caused by AD or CADASIL.
We have recently demonstrated the therapeutic effects of bone marrow stem cell factors on brain repair in animal models of stroke, Alzheimer's disease and CADASIL disease. Our laboratory is studying how the bone marrow stem cell factors repair the brain in these devastating diseases. In addition to the in vivo study, we are also determining how the bone marrow stem cell factors regulate neuronal process formation, synaptic generation, and stem cell growth, motility and differentiation. We are also gaining an understanding of the detailed process of how stem cells promote neuronal network development.
