Fluorescence of dyed mitochondria (a) and autofluorescence of NADH (b) in keratinocytes (zoom 3.0). Fluorescence of dyed mitochondria (c) and autofluorescence of NADH (d) in a single keratinocyte (zoom 7.9).

(a) Comparison of mitochondrial networks in young volunteers and old volunteers before and after binarization. Age-related comparison of size (b) and circularity (c) of mitochondrial clusters in keratinocytes. The p-value represents the probability if the two compared probability distributions derive from the same population. The square in the box represents the mean value, the horizontal line in the center the median. 25% percent of the measured values are lower than the bottom of the box, 75% of them are lower than the top of the box. The antennas (whiskers) are the corresponding limits for 2.5% and 97.5%. Crosses represent the highest and the lowest value in the distribution.

(a) Comparison of mitochondrial networks in stratum spinosum and stratum granulosum representing different states during the differentiation process of keratinocytes. Differentiation-related comparison of size (b) and circularity (c) of mitochondrial clusters in keratinocytes. The p-value represents the probability if the two compared probability distributions derive from the same population. The square in the box represents the mean value, the horizontal line in the center the median. 25% percent of the measured values are lower than the bottom of the box, 75% of them are lower than the top of the box. The antennas (whiskers) are the corresponding limits for 2.5% and 97.5%. Crosses represent the highest and the lowest value in the distribution.
