...dy and invade other tissues. Head and neck cancers originate on the epithelium the layer of tissue covering the outermost surfaces of the body, including the skin and mucus membranes. Kaposi's sarcoma tumors arise from the endothelium, the cells that line blood vessels. "The vast majority of endostatin studie...Scientists close in on understanding learning and memory

The sites listed originate from mammals, insects and nematodes, and all are supported by good experimental evidence. These experiments provide essential information about the in vivo properties necessary for binding that are not contained in the sequence alone.

...ord University, determined where many microtubules originate and how some of them move around to become organized in epidermal cells. The results are published in the April 24, 2003, Science Express. The scientists were able to image individual microtubules in a transgenic plant of the mustard family, Arabido...Scientists debate meaning of 40-million-year-old primate fossils in Nature
...trary to a widespread assumption, primates did not originate in Africa. The new fossil evidence supports a novel proposal that lemurs, lorises and bushbabies, which comprise a sister group to higher primates, might have originated in Indo-Madagascar rather than in Africa. So says Robert D. Martin, Provost and ......g cells), the scientists found. These cells, which originate in the blood system, reach a developing kidney only after ten weeks. After growing the human and porcine kidney tissue in mice, the scientists checked how human lymphocytes (fighter cells in the immune system) might react to it.

... 20 million to 40 million people worldwide did not originate from birds, as previously thought. Wild waterfowl collected between 1915 -1919 were tested for the same hemagglutinin (HA) subtype as that of the 1918 pandemic Influenza A virus. The tests concluded the HA genes were different.
