11. In it, they reported that they had grown entire mice from individual cells that they had plucked from mouse embryos. 12. In one experiment Verfaillie said her lab tagged MAPCs with blue dye and then injected them into early stage mouse embryos. 13. Research has proven that stem cells taken from mice embryos can be injected into the spinal chords of paralyzed mice and spark recovery. 14. Since mouse DNA was largely decoded, and is suprisingly similar to human DNA, scientists could inject a human gene into a mouse embryo and see what happens. 15. The researchers knocked out the bax gene in mouse embryos, creating a gene defect that seemed to produce no harmful effects in the animals later in life. 16. Their work shows that genetically identical mouse embryos implanted in different wombs end up performing differently at mental tasks. 17. Using cells from mouse embryos, they produced three mice that were genetically identical, and cleared the way for experiments with larger mammals. 18. When scientists make mice with foreign genes, they first insert them into mouse embryos, then allow the mice to develop to maturity. 19. When the mouse version of MAP cells are injected into a mouse embryo, they help form all the tissues of the body, just as embryonic cells do. 20. He starts by taking cells from mouse embryos and squishing them between two glass plates in a five-centimeter square, loaded with tiny electrodes. |
