Read the following article on experiments that mix human and animal cells. Then consider the following quotation from the article. We have highlighted one word in red.
Yale researcher Gene Redmond: "There seems to be little or no chance that the monkeys would be 'humanized,'" because of the relatively few and highly specialized human cells that are being implanted"
