Fig. 2. StripeA is hardly detected when muscle-tendon interaction is
abrogated. Dorsal view of stage 16 wild-type (A-D) or
myospheroid (mys) mutant (E-H) embryos or embryos
overexpressing Hid in muscle cells (I-L), stained with anti-StripeA
(red, A,E,I) anti-Stripe (Blue, B,F,J) anti-Myosin heavy chain (MHC; green,
C,G,K). The corresponding merged panels are shown in D,H and L. Arrowheads
(E,F,H) or arrows (I,J,L) show that in mys mutants, or in regions
where muscle are lacking, all tendon precursors express StripeB, but StripeA
is significantly reduced or completely absent.
