Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down’s syndrome, suggests new research carried out in mice at the University of Cambridge. In a study published today in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing – and in some cases completely fixing – the embryo.

Genetic ‘signatures’ of early-stage embryos confirm that our development begins to take shape as early as the second day after conception, when we are a mere four cells in size, according to new research led by the University of Cambridge and EMBL-EBI. Although they seem to be identical, the cells of the two day-old embryo are already beginning to display subtle differences.

The journey from a single fertilised egg cell through to a baby delivered crying into the arms of its mother is one of the most beautiful and complex processes to occur in nature. We are only just beginning to understand the very earliest stages of life – when we are nothing more than a cluster of cells.

We know much about how embryos develop, but one key stage – implantation – has remained a mystery. Now, scientists from Cambridge have discovered a way to study and film this ‘black box’ of development.
