Last week, researchers led by Spanish scientist Juan Carlos Izpisua Belmonte announced they had created the first human-monkey chimera embryos in China. The purpose of the experiment is to investigate ways of using animals to grow human organs for transplants. The organs could be genetically matched by taking the recipient’s cells and reprogramming them into stem cells.
Human-pig
In 2017, scientists from the Salk Institute in California (led again by Izpisua Belmonte) tried to grow the first embryos containing cells from humans and pigs. The process proved to be more challenging than expected and was very inefficient: from 2,075 implanted embryos, only 186 developed up to the 28-day time limit for the project.
Human-mouse
In March, Japan loosened its guidelines, lifting a two-week limit on the growth of human-animal chimeras and allowing the transplantation of chimeric embryos or hybrids into animals, but not humans. Pending approval, a Japanese stem cell scientist, Hiromitsu Nakauchi, plans to insert human stem cells into mice or rats in an attempt to grow a human pancreas in the animal. As a safeguard, if too many human cells creep into the rat’s brains, the experiment will be stopped.
Dr Pretorius asks his former student Dr Frankenstein to help him create a woman from "The Bride Of Frankenstein" (1936):
"You think I'm mad. Perhaps I am. But listen Henry Frankenstein. While you were digging in your graves, piecing together dead tissues, I, my dear pupil, went for my material to the source of life. I grew my creatures like cultures; grew them, as Nature does - from seed. But still, you did achieve results that I have missed. Now think what a world-astounding collaboration we should be, you and I - together. Leave the charnel house and follow the lead of Nature - or of God if you like your Bible stories. Male and Female created He them. Be fruitful and multiply. Create a race, a man-made race upon the face of the earth. Why not? Our mad dream is only half realized. Alone, you have created a man. Now together, we will create his mate. Yes. A woman. That should be really interesting."
