New Types Of Morpho-Physiological Changes In Cells Exposed To Nanosecond Pulsed Electric Field, Mikhail A. Rassokhin
New Types Of Morpho-Physiological Changes In Cells Exposed To Nanosecond Pulsed Electric Field, Mikhail A. Rassokhin
Theses and Dissertations in Biomedical Sciences
Exposure of cells to a pulsed electric field (PEF) is the basis of multiple techniques and treatments. Nanosecond pulsed electric field (nsPEF) poses unique characteristics to induce subtle cellular effects while preserving cell integrity. Improving understanding of the mechanisms triggered by nsPEF in cells inspires new applications for the nanosecond pulse technology. Although many effects of nsPEF remain unknown, they can be inferred from morpho-physiologic changes, or cell reshaping, that accompany nsPEF exposure. During the exposure cells undergo reshaping that is manifested in swelling and diffuse blebbing. Recently we identified two new distinct forms of reshaping, pseudopod-like blebbing and microvesiculation, …
Attachment Ability And Melanoma Inhibitory Activity Mrna Expression Level Changes In Murine B16-F10 Melanoma Cells Post Nanosecond Electric Pulses, Hongxia Jia
Theses and Dissertations in Biomedical Sciences
The effects of high-voltage nanosecond electric pulses (nsEPs) on metastatic melanoma are still unclear. Hence, we applied one, two, three, and four 300 ns 40 kV/cm pulses to murine B16-F10 melanoma cells. Cell attachment ability was determined by comparing the number of floating cells and the percentage of attached cells. Melanoma inhibitory activity (MIA) is a secretory protein that is highly correlated with the malignancy and metastasis of malignant melanomas. We used MIA as our target to evaluate the effect of nsEPs on metastasis. Pulsed (experimental) and unpulsed (control) cells were incubated at 37°C under a 5% CO2 atmosphere. …
