Presence of ES cells could be excluded by culture in the presenve of JAK inhibitor, and monitored by Oct4 and Nanog immunostaining.
(続き)A global transcriptome anallysis could then be performed for comparison with TS cells. Data should also be provided on Fgf4 withdrawal from the TS-like cells - does this induce the expected differentiation into trophoblast giant cells?
レフェリー#1は、1回目査読と2回目査読で同じ人のようです。出だしの文章が同じです。青字部分 1回目 In the present manuscript the authors evaluate the role of cellular stress during potential nuclear reprogramming toward pluripotency.
2回目 In the present manuscript the authors leverage on an accompanying manuscript in which they described reprograming induced by stress.
Ref 2は以下のように書いています。ここは上記の一言居士さんの文章と同じ部分です。 The authors suggest that STAP cell-derived TS-like cells are distinct from embryo-derived TS cells, but the data for this are not decisive and could be attributed to persistent contamination with STAP cells or ES cells (which could explain the occasional Nanog positive cells). Presence of ES cells could be excluded by culture in the presence of JAK inhibitor, and monitored by OCT4 Nanog immunostaining. A global transcriptome analysis could then be performed for comparison with TS cells. Data should also be provided on Fgf4 withdrawal from the TS-like cells –does this induce the expected differentiation into trophoblast giant cell?
>Previous studies have indicated that inner cell mass (ICM)-type pluripotent cells can be removed from culture by treating the culture with a JAK inhibitor16 (Extended Data Fig. 5a, b). In contrast, the JAK inhibitor treatment had no substantial effect on Oct4-GFP expression in Fgf4-induced stem-cell culture (Extended Data Fig. 5c, d; see Extended Data Fig. 5e, f for control). Expression of neither pluripotency markers (Fig. 2j) nor trophoblast markers (Fig. 2k) was substantially affected, indicating that pluripotency marker expression is unlikely to reflect contaminating STAP stem cells (ICM-type).
