And once this entire process is better understood, what if those stem cells could be manipulated in a laboratory to become skin if they are fed certain nutrients, but turn into certain types of brain cells if they are given other ingredients? (spinalcordinjuryzone.com)
To create these cell lines in the laboratory, cells have to be taken from the blastocyst stage of the human embryo. (spinalcordinjuryzone.com)
This involves fertilizing an embryo in a laboratory instead of inside the female body. (healthline.com)

if it implants and the pregnancy goes to term, the resulting individual will carry the same nuclear genetic material as the donor of the adult somatic cell. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
DNA (deoxyribonucleic acid) is the cell's genetic material, contained in chromosomes within the cell nucleus and mitochondria. (msdmanuals.com)
