1.   The virus proved highly selective in killing several lines of human cancer cells in laboratory cell cultures.

2.   But these cells would grow only briefly in laboratory cultures.

3.   Current E. coli detection methods, which use laboratory cultures, take up to eight hours.

4.   Farris developed a special laboratory culture containing ground-up kudzu leaves and used it to grow the fungus.

5.   Hayes and his neurosurgery department team have accomplished the gene transfer in laboratory cell cultures and are now working with rats.

6.   Milner has also studied five human tumors in laboratory cultures and has shown that one garlic compound, diallyl disulfide, is very effective in inhibiting tumor growth.

7.   That estimate is derived from thousands of studies of people worldwide and is supported by findings in laboratory cell cultures and experimental animals.

8.   The protein was chosen because it was the most common in laboratory cultures of Borrelia.

9.   The researchers tested resveratrol on human neural cells in laboratory cultures and found that it made them grow small extensions through which they could connect with neighboring cells.
