Since the 1990 s on, about 10000 years ago for resurrection extinct mammoth unremitting discount sunglasses research on Japanese scientists have expressed looking forward to say: "the discovery of bone marrow improve the resurrection of the mammoth possibilities."
Mammoth leg bone unearthed from Louis saha thigh republic of north permafrost. The country's capital of mammoth YaKuCiKe museum researchers last month to 13, cutting the leg bone inspection found that the internal existence state of frozen bone marrow. The museum curator agent introduced says: "the first kept intact mammoth see so. Is fresh bone marrow, I immediately feel this is a valuable cheap nfl jerseys discovery."

Into the valley expressed: "look at the photos, bone marrow, very full, raised the possibility of mammoth higher."
According to the research group introduction, extract the nuclei from bone marrow and implant had its nucleus removed an elephant can obtain contains mammoths gene of the embryo, then implanted in the womb elephants, then to have the possibility to produced mammoth.
The technology is called "somatic cell nuclear tra lants", is a kind of cloning technology. Use this technology to extract from mammoth organs in the bone marrow, containing genes skin, muscle, organs and the nucleus. However, due to the extraction of the nucleus is very difficult, and has long become difficult to cross the resurrection mammoth obstacles.
But, according to kinki university research group introduction, in the past two or three years have witnessed a nucleus extraction technology progress.
