Measuring a few millimetres across, the pieces of intestinal tissue made by the month - long process contain all the cells and features found in normal gut tissue, and grow by the same route as in embryos.

The finding that normal fertilization can result in embryos containing cells with different parental sets of chromosomes is a new mechanism for chimerism, which was previously thought to occur only as the result of fertilization errors, for example, the fusion of multiple sperm or eggs to form an embryo.

However, during normal fertilization, when an egg and a sperm fuse, the sperm's mitochondria are destroyed, as the embryo inherits only its mother's mitochondria.

After an egg has been fertilized by a sperm, normal embryos follow clear - cut timeframes for development, such as the time it takes for a two - cell embryo to turn into a three - cell embryo, and the time it takes for a three - cell embryo to turn into a four - cell embryo.

They artificially differ from normal two - cell state cells, however, and while possibly useful, their roles in research, such as models for embryo development, will need to be assessed.

In a developing embryo, stem cells can differentiate into all the specialized cells, but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.

With these aspects in mind, I would certainly want to see this used in mutations with single nucleotide substitutions (variants) that characterize most ADAD mutations, and like to see the further development of the embryos as it relates to normal development after the normal sequence is introduced.

Scientists discovered that when this occurs, a DNA repair process employed within human embryos activates to fix the broken gene, using the normal copy of the gene as a template.
