Web1 mrt. 2024 · In T150D K5 YFP keratinocytes, diffuse keratin fluorescence predominated in the cytoplasm. In addition, very small fluorescent dots were detected moving at random throughout the cell. Several of the brightest dots were seen at the tips of cell protrusions. They were short-lived and had an overall tendency to move inward. WebThey grow at a room temperature of 25-27 degrees Celsius, on keratin surfaces with low temperatures. They are keratotic, so they tend to live in keratin-rich environments including hair and skin. Susceptibility to Disinfectants. ... Fluorescence is due to the presence of pteridine pigment in the cell wall.
