(A-C) Telophase GSCs marked by H3S10p (gray) expressing old (green) and new (red) histone H3 show non-overlapping patterns (A). Telophase GSCs expressing old (green) and new (red) histone H4 show moderate levels of overlap (B). GSCs expressing old (green) and new (red) histone H2A show high levels of overlap (C). (D) A control where the old and new fluorescent tags have been switched shows the non-overlapping patterns of old (red) versus new (green) H3Rev histone in mitotic telophase GSCs marked by H3S10p (gray). (E) Quantification of log2 ratios of total old and new histone inherited by each future daughter cell of the GSC division, where a value of 0 is equal inheritance at exactly a 1:1 ratio. Data gathered over 9 separate experiments for H3Rev GSCs, H2A GSCs, and H4 GSCs. Data gathered over 16 separate experiments for H3 GSCs. Values are mean + 95% CI. (F-H) Telophase CBs marked by H3S10p (gray) expressing old (green) and new (red) histone H3 also show non-overlapping patterns. (F) Telophase CBs expressing old (green) and new (red) histone H4 (G) and H2A (H), which depict more overlap like GSCs. (I) A control with switched old and new fluorescent tags shows the non-overlapping old old (red) versus new (green) H3Rev histone patterns in mitotic telophase CBs marked by H3S10p (gray).
