is it possible to use dna from hair to make a human egg?

If you could take the DNA out of a human egg and replace it with the DNA from your wife's hairbrush, you could have a child with the exact same DNA as your wife, an 'identical twin' (actually a clone).

But AFAIK this has never actually been done, it's just something people are talking about.

If you're really serious about it, call up a local IVF lab (In Vitro Fertilization) and ask them if that's possible.

I'm very sorry about your loss, but I think that you need to get some sort of professional assistance with dealing with your grief. Human cloning isn't the answer you're seeking. While the technology does exist today to successfully clone any mammal, including human beings, it may not be the solution you think it is. A human clone is an identical copy of the original genome used in cloning; the clone comes into the world just like any other fetus would, and requires the same kind of care. The human clone grows and matures just like any other person would. So, even if you could clone your departed wife, it could never be the same as before. You would always be decades older than her at every point in time. You wouldn't be satisfied with the outcome.

DNA in her hair still in her hairbrush: this is not likely to be a good source of viable DNA. The hair itself is not made up of DNA. The DNA is in the hair follicle. The follicle is in the skin of her scalp and does not come out with the hair itself. The hair itself is made up of a protein called keratin. Proteins cannot be used in cloning, only DNA.

It is obviously a painful time for you right now, but you will be able to recover and then get on with your life.

Best regards

The technology currently does not exist to do what you are suggesting. Right now, only a stem cell can be coaxed into a different structure (at least with female DNA), and follicular DNA is not in that category.

That being said, the technological hurdles are not insurmountable and are being researched. Try not to get hopes up, though, as practical application of such a biomedical advance would likely be at least a decade away without a massive increase in the speed of advancement in applied genetic technology as well as possible repeal of numerous laws against human genetic tampering.

My heart goes out to you.

Yes. I once got a girl pregnant from "coming" in her hair. At least thats what she claimed.
