Optimization Of Labeling Techniques; Determination Of Best Parameter For Olfactory Mucosal Progenitor Cell Delivery And Study Of Effects Of Methylene Blue And Polyethylene Glycol In An Animal Model Of Spinal Cord Injury, Kiran Kumar Rokkappanavar

Wayne State University Theses

In the United States, the incidence of TSCI is about 40 per million persons per year, with approximately 250,000 living survivors of TSCI in the United States in July 2005. A number of human clinical trials (85) are ongoing using stem cells to evaluate the methods to reduce the injury following TBI. Among the stem cells, olfactory mucosal progenitor cells have several advantages with respect to ease of obtaining, fate of cells, etc. Our study was intended to optimize the labeling technique and to determine the best parameter to deliver the stem cells to the site of injury. We found …

Studies Of Regulated Exocytosis From Neuroendocrine Cells, Madhurima Das

Wayne State University Theses

In this thesis we study cargo release and fusion pore dilation during calcium triggered exocytosis and the co-localization of calcium sensing proteins essential for exocytosis, in neuroendocrine cells.

Pancreatic beta cells secrete several hormones, the most studied one being insulin. C-peptide is a protein which is co-stored with and secreted from the same vesicles as insulin. It is found in the soluble phase unlike insulin, which is found in the dense core. The pancreatic beta cells also secrete the Chromogranin B (CgB) which is mostly found in the dense cores of secretory vesicles. In chapter 1, we found that CgB, …
