The purpose of this study was to evaluate the effects of activin A on the developmental competence of in vitro fertilized (IVF) bovine embryos derived from a two-step defined culture system (C1/C2 medium) during the early or later stages of embryo development. The authors suggest that activin A, during the later stage of in vitro bovine embryo development, can enhance in vitro development of embryos by increasing hatching rates and affecting expression levels of genes related to hatching and implantation in defined culture medium.
The formula of C1/C2 medium is listed in a former article.--> Lim, K. T., Jang, G., Ko, K. H., Lee, W. W., Park, H. J., Kim, J. J., ... & Kang, S. K. (2007).
