A, Overexpression of human WT but not mutant ARPC1B mRNA (150pg) partially rescued the thrombocyte development in 3.5dpf Tg(CD41:EGFP) embryos (lateral view, red rectangles) treated with arpc1b-i3e4 MO (Arpc1b). The numbers refer to the fractions of embryos exhibiting the depicted phenotypes. B, Quantitation of EGFP+ cell numbers in the CHT region as depicted in the red boxes of Fig. 6A as the mean of five embryos of each phenotype. T bar indicates the standard deviation. C, Overexpression ARPC1B in arpc1b morphant embryos using heat-shock inducible plasmids (150pg) encoding WT or mutant human ARPC1B. Developing T cells were identified by performing WISH analysis at 5dpf for using a probe for lck (blue circles, lateral view). The numbers refer to the fractions of embryos exhibiting the depicted phenotypes.
