Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after fertilization. The findings, published in Nature Communications, may eventually contribute to improved fertility treatment.
