Fig. 1From: Hormetic effects of mild heat stress on the primary culture of mouse prefrontal cerebrocortical neuronsFluorescence micrograph of the primary cultured mouse prefrontal cerebrocortical neurons stained by Calcein-AM and propidium iodide. Green fluorescence indicates functional esterase activity in the live cells, and orange fluorescence indicates the staining of nuclei in dead cells by propidium iodide. Note that a higher number of viable neurons (green fluorescence) in the mild heat stress group and a greater number of dead neurons (orange fluorescence) in the control groupBack to article page
