Master of Science / Department of Anatomy and Physiology / Mark L. Weiss / Wharton's jelly is a non-controversial source of mesenchymal stromal cells. Isolation of the cells is non-invasive and painless. The cells have been shown to have a wide array of therapeutic applications. They have improved symptoms when transplanted in a variety of animal disease models, can be used in tissue engineering applications to grow living tissue ex vivo for transplantation, and can be used as drug delivery vehicles in cancer therapy. The cells have also been shown to be non-immunogenic and immune suppressive. This thesis focuses on optimizing isolation protocols, culture protocols, cryopreservation, and characterization of cells in different growth conditions.
Results from the experiments indicate that isolation of cells by enzyme digestion yields cells consistently, a freezing mixture containing 90% FBS and 10% DMSO confers maximum viability, and the expression of mesenchymal stromal cell consensus markers does not change with passage and cryopreservation. The results of the experiments also show that cells grow at a higher rate in 5% oxygen culture conditions compared to 21% oxygen culture conditions, serum does not have an effect on growth of the cells, serum and oxygen do not have effects on the expression of mesenchymal stromal cell consensus markers and the cells are stable without nuclear abnormalities when grown in 5% oxygen and serum free conditions for six passages after first establishing in serum conditions.
