Fig. 6. Expression of the PTB domain rescues the LvNumb morpholino
phenotype. (A) Embryos injected with control morpholino have normal
levels of pigment cells. (B) Injection ptb domain mRNA (2
pg/pl) increases pigment cell specification. (C) Pluteus larvae
injected with LvNumb morpholino (1.7 mM) showed pigment cells specification in
less than 9% of the embryos examined. (D) Injection of ptb
domain mRNA with LvNumb morpholino showed pigment cells specification in
77% of the embryos examined. Inset, high magnification of embryo in D.
