Fig. 5. Number of dead cells detected by TUNEL analysis and Hoechst staining of blastocysts from gp130+/- intercross matings delayed for 3 days. Wt/het, combined gp130+/+ and gp1+/-; null, gp130-/-. Error bars denote standard deviation. Using Students t-test significantly more dead cells per embryo are detected in the gp130-/- category: P<0.01 using TUNEL analysis; P<0.002 by Hoechst staining.
