WASHINGTON, D.C. - A local teenager's research on stem cells earned him and his partner $30,000 at a national math, science and technology competition.

Aaron Argyres and his teammate, Mingu Kim of Columbia, Missouri, designed a material that would help determine the chemical future of stem cells.

"So what we wanted to do is create a material that would use certain mechanical cues that it had to determine the cell type," Argyres said in an interview with NewsChannel 5's Heidi Glaus in November. "We found that when we grew the stem cells on this material it would determine their fate to become bone cells."

Argyres and Kim, who finished fourth out of the six finalists, will split the prize money.
