101.   West argued that thousands of cell lines might eventually be necessary.

102.   When these cell lines are perfected they will be state of the art, while federally funded researchers will be limited to more primitive Bush-approved cell lines.

103.   Wisconsin researchers isolated some of the first embryonic stem cell colonies and now have five cell lines in hand.

104.   Over time, all cell lines kept in laboratories accumulate harmful mutations and there is no reason to expect stem cells to be any different, the report said.

105.   Parikh said his facility would continue to make new embryonic cell lines for use by privately funded scientists in collaborative research.

106.   A single embryo creates a single cell line, which can replicate itself indefinitely.

107.   As a result, Cohn said, WARF believes that virtually all of the other embryonic cell lines now in existence come under the Thomson patent.

108.   As is customary there, he turned the patent for five cell lines and for the method of deriving them over to the Wisconsin Alumni Research Foundation.

109.   At Karolinska Institute in Stockholm, which NIH said had five cell lines, officials said the colonies are not scientifically ready for research.

110.   Beyar said the cell lines may be licensed to U.S. investigators, but there are financial and patent considerations to be resolved.
