to edit a human embryo or the sperm and egg (or the adult cells that produce sperm and eggs, as another MIT Tech Review story points out) used to create the embryo — something called "germ line editing." Editing an embryo wouldn't just remove a There are two types of cell division: mitosis, which is observed in somatic cells such as skin, and meiosis, which occurs in the germ cells that produce sperm and eggs and reduces the chromosomes in half. In mitosis, the replicated chromosomes (sister to edit a human embryo or the sperm and egg (or the adult cells that produce sperm and eggs, as another MIT Tech Review story points out) used to create the embryo — something called "germ line editing." Editing an embryo wouldn't just remove a Known as germline modification, making genetic changes to embryos, eggs or sperm are of particular concern because a person created using such cells would have had their genetic make-up changed forever. The fear is that germ-line engineering takes mankind that the designer stem cells lack some of the genetic problems that other cells have. “We have also discovered that one of the things that happens in these germ cells is that epigenetic mutations, the cell mistakes that occur with age, are wiped out Dr. Freiman’s team was able to examine mice with and without the TAF4b gene to determine its effects on gonadal cell development. In mice with intact TAF4b, germ cell progenitors in male embryos were able to proliferate normally, developing the proper .
He began by discussing germ lines, the cells used for sexual reproduction. “Germ lines exist on a cosmic time scale. Every animal on this planet is related to each other — we’re all related to each other.” The germ lines of humans and nematodes They claim it is possible for human cells to be grown using only stem cells or 'germ cells' taken from the skin of the two prospective parents. Naturally this 'designer baby' method has been met with controversy, with some people voicing concerns over Mice lacking the gene for the protein TAF4b (right) produce fewer undifferentiated germ cells (green) than mice with the gene (left). Credit: Freiman lab/Brown University TAF4b is a protein that affects how genes are regulated and transcribed, and its "We have also discovered that one of the things that happens in these germ cells is that epigenetic mutations, the cell mistakes that occur with age, are wiped out," added Surani, was also involved in the birth of the first test-tube baby, Louise Brown .
