Chinese scientists have bred a chimera monkey with two DNA. This is reported by the journal Cell reports.
Thus, molecular biologists managed to grow from embryos of baby monkeys with two sets of pluripotent stem cells, which are closest in their properties to those corpuscles that appear in embryos in the first phases of development.
In particular, during the experiment, biologists grew nine different lines of stem cells macaque crab-eating macaques, then built into their DNA a set of genes that made these cells produce fluorescent glow.
These cells were then transplanted into embryos grown from stem cells and transferred into the bodies of surrogate mothers.
Soon six "chimeric" macaque crab cubs were born, but only one proved viable. After 10 days, the cub was put to sleep due to respiratory failure and hypothermia.
The study showed that its body tissues were 67% composed of the luminescent descendants of modified stem cells.
