Scientists can clone a mouse from a single drop of blood
A team of Japanese scientists managed to successfully clone a Mouse from a drop of blood taken from the tail of the donor, which would no longer be necessary to euthanize the animal for harvesting their cells, because when performing cell nuclear transfer – the same technique used to clone Dolly the sheep – is necessary to sacrifice the animal donor.
This would be of great relevance when to clone endangered animals or laboratory animals only. The new technique demonstrates that a mouse can be cloned from the white blood cells of a blood sample, instead of using the nuclei of peripheral blood cells which are extracted from white blood cells of the lymph nodes, bone marrow and liver.
According to Japanese scientists, Bioresources Center RIKEN , the cloned mouse had a normal life span and is able to reproduce. Now just need to wait for the technique to be successful with other larger mammals for use in animals and endangered, among many other purposes.
