Figure 3From: Determine the quality of human embryonic stem colonies with laser light scattering patternsFluorescent images of hESCs colonies. Immunohistological staining assay was applied to determine the qualities of hESCs colonies. Anti-Oct-4 antibody was used to label the self-renewing pluripotent stem cells in colonies. Results indicated the existence of more Oct-4 marked cells in categorized good hESCs colonies (a) versus those of bad hESCs colonies (b).Back to article page
