Markers of ATP reduction and the unfolded protein response (UPR) were detected by Western blot. WebBar graphs on the right show corresponding absolute cell numbers (nr) per FL. Total FL cell counts are the mean (± SD) of 12 wild type and 13 Sl/Sl embryos. Tail somite range: 10–16 (wild type), 12–15 (Sl/Sl). Note that although EMP frequency in Sl/Sl FL is increased, their absolute number is severely decreased.
