Table 2. Rescue experiments with heat shock fn1a-mKikGR at the 10–12 somite stage on pre-sorted fn1a^-/-; fn1b^-/- embryos.

For each experiment, fn1a^-/+; fn1b^-/+;hsp70: fn1a-mKikGR adults were crossed and embryos sorted for the fn1a^-/-; fn1b^-/- morphological phenotype were heat shocked at the 10–12 stage and assayed for somite border defects at 24 hpf. 1 or two embryos per experiment were not heat shocked as a control. Four experiments were performed and the numbers shown in the table represent the total number of embryos with each phenotype. * HS at the 12-somite stage will rescue body elongation and head development defects observed in the fn1a^-/-; fn1b^-/- embryos, however heat shock will not fully rescue border defects of the first 1–6 somites.
