From: The effect of temperature on the viability of human mesenchymal stem cells
Light microscope images of human mesenchymal stem cells. Images taken at the end of the experiment showing the human mesenchymal stem cells in culture 7 days after heat treatment at 48°C for 150 seconds (a), (b) and at 58°C for 45 seconds (c), (d). Normal spindle morphology with cell interactions can be seen after treatment at 48°C for 150 seconds, whereas cell damage is clear 7 days after heat treatment at 58°C for 45 seconds with only cell debris remaining. The threshold for cell survival lies between these two conditions of heat exposure. (a), (c) Scale bar = 500 μm. (b), (d) Scale bar = 250 μm.
