Stress-activated protein kinase/c-Jun kinase (SAPK/JNK) is thought to be necessary for preimplantation embryonic development (Maekawa et al., 2005). However, media increases SAPK/JNK phosphorylation and these levels negatively correlate with embryonic development (Wang et al., 2005). Culture-induced stress could confuse analysis of the role of SAPK in development. In this study, we tested how SAPK/JNK inhibitors influence embryonic development in optimal and non-optimal media and define the contribution of cell survival and proliferation to the embryonic response to these media. SAPK/JNK inhibitors retard embryonic development in suboptimal Ham’s F10, but improve development in optimal potassium (K+) simplex optimized media (KSOM) +AA. …
