Long-Term Effects Of Notch1 Signaling On Neural Stem Cells Following Traumatic Brain Injury, Cruz Sevilla Jr Jan 2019

Long-Term Effects Of Notch1 Signaling On Neural Stem Cells Following Traumatic Brain Injury, Cruz Sevilla Jr

Theses and Dissertations

Traumatic brain injury (TBI) is a devastating problem which stands as a leading cause of death and disability. The elderly is significantly affected by TBI, typically as the result of falls, and recovery is especially limited. This, in part, is associated with decreased tissue-specific stem cell regeneration and replacement of damaged cells in the aged brain. The diminished ability of the aged brain to recover is especially devastating after TBI, likely leading to permanent loss of sensory, motor, and cognitive functions. Studies have shown that the mature mammalian brain contains Neural Stem Cells (NSCs), found in specific regions of the …


Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong Jan 2019

Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong

Theses and Dissertations

Bone defects are a pervasive complication arising from many clinical conditions, both mechanical and pathological. Current treatments for large bony defects focus on applying bone grafts or synthetic materials to the defect area. Cell-based—and especially stem-cell—therapies have advanced greatly thanks to increasing attention focused on their ability to generate new tissues in situ with biomechanical properties approaching that of native tissue, but they suffer from their own shortcomings as well. Exosomes have been shown to play critical roles in cell-signaling and tissue regeneration and are therefore potentially ideal therapeutic vehicles for treating bone defects. Exosomes are small microvesicles counted amongst …
