Knockdown of klf8 affected dorsal forerunner cell number, KV cilia number and length. Cell number of dorsal forerunner cells (DFCs) was affected in klf8-MO1^atg- or klf8-MO2^atg -injected embryos as compared to klf8-4 mm MO1-injected Tg(sox17:gfp) control embryos (4 mm) at 75% epiboly (a-d). Images of KV cilia stained with acetylated tubulin antibody in klf8 morphants (g-i) and control embryos (e, f) at 10s stage (e-i). Images of acetylated tubulin stained KV cilia and GFP stained DFCs in Tg(sox17:gfp) embryos injected with different klf8 MOs (l-n), klf8-4 mm MO1 (k) or wild type (j) embryos at 10s stage (j-n). DFC number (o), KV cilia number (q), length (r) but not lumen area (p) were affected in klf8 morphants as compared to control embryos. Statistical significance was determined by Student’s t-test. *p < 0.05, **p < 0.01, ***p < 0.001. Error bars indicate standard deviation
