Genómica funcional en embriones y ovocitos humanos individuales

During three decades human embryo and oocyte analyses have been performed based on morphological or cytogenetical evaluations; molecular techniques, like FISH and PCR, have been gradually incorporated. However, the development of new techniques of individual cell RNA amplification has allowed the analysis of gene expression in oocytes, cumulus-oocyte complex and preimplantation embryos. These techniques will change radically the study of human reproductive biology and assisted reproduction, allowing a powerful and objective analysis of the complex processes and the interactions that may explain the causes of infertility and generate new therapeutics.
