Human embryonic stem cells (hESCs) are a promising cell source for tissue engineering and regenerative medicine, but before they can be used in therapies, we must be able to accurately identify the state and progeny of hESCs. You can apply this statistic to a particular fluorescence (I understand that this means: mean of fluorescence/cell). Image color quantification (manual): This method involves visually assessing the intensity of the immunofluorescent staining in the predetermined regions of interest and assigning a numerical score to it. Figure 9.
