Whole Organ Grown In Animal For First Time
An anonymous reader writes British scientists have produced the first working organ grown from scratch in a living animal. Reprogrammed cells created in a lab were used in a mouse to produce a thymus. The organ was created using connective tissue cells from a mouse embryo and were converted into a different cell strain by changing a genetic switch in their DNA. The resulting cells grew into the whole organ after being injected. It has only been tested on mice so far, but researchers at Edinburgh University say that within a decade the procedure could be effective and safe enough for humans. The findings were published in Nature Cell Biology.
This is big pharma. There's a university-industrial complex out there, that researches then produces new treatments. This is step 1 of how those companies you hate make a new product.
It'd be really nice for people who were born without the organs in question. First it'll probably be for people with a straight-forward birth defect, but eventually, this could possibly grow gonads for trans people, allowing their bodies to produce their own hormones. I'd be pretty excited if I could eventually stop taking synthetic estrogens.
That's not really clear in any sense.
It comes down to the definition of "individual". The zygote is the first case where you are genetically complete at probably 99.99+% of the same genes you have as an adult. But are you your genes?
Can a zygote truly be referred to as an individual? If so, why can't an egg? Is your definition of "individual" a clump of cells that share the same gene sequences? If so, then are twins two individuals? Why or why not?
We have an intuitive notion of what these things mean and it works after a baby is born and it gets weirder the earlier you go.
