Fig. 4. N14 mutation does not affect the distribution of pole plasm components. Wild-type (A-D) and N14^m– (E-H) embryos at the cellular blastoderm stage. Embryos were stained for nanos RNA (A,E), gcl RNA (B,F), pgc RNA (C,G) or Nanos protein (D,H). These RNAs and protein were incorporated normally into pole cells in N14^m– embryos (E-H) as in wild-type embryos (A-D).
