Mouse cloned from drop of blood

0

Scientists in Japan have cloned a mouse from a single drop of blood.


Circulating blood cells collected from the tail of a donor mouse were used to produce the clone, a team at the Riken BioResource Center reports in the journal Biology of Reproduction.

The female mouse lived a normal lifespan and could give birth to young, say the researchers.

Scientists at a linked institute recently created nearly 600 exact genetic copies of one mouse.

Mice have been cloned from several different sources of donor cells, including white blood cells found in the lymph nodes, bone marrow and liver.

      There you go, if humans can create mice from a mere drop of blood, surely Allah could have created humans from a whole clot!

      Are you suggesting that Big Al created mankind from MuHAMmad?

      • Allah forbid! :)

  1. As someone with a degree in genetics, I must say that this is huge news. The biggest problem with cloning has been defective clones caused by damage done to the donor cell’s DNA by the extraction of the nucleus. Too bad we’ll never see this used in humans.

    • It’s true that erythrocytes (red blood cells) don’t have nuclear DNA – they lose their nuclei as they mature and become nothing but bags of hemoglobin in order to carry the maximum amount of oxygen. The full article at BBC says they used leukocytes (white blood cells), which are nucleated. I wish articles on cloning would make this clear, because so many people assume that DNA testing and cloning can be done with “blood”.

      I learned in high school 50 years ago that red blood cells don’t have chromosomes. Wouldn’t that make them useless for cloning? Did they use white blood cells or some other blood product?
