Cells As Building Blocks
Tissue engineering utilizes living cells as engineering materials. Examples include using living fibroblasts in skin replacement or repair, cartilage repaired with living chondrocytes, or other types of cells used in other ways.
Cells became available as engineering materials when scientists at Geron Corp. discovered how to extend telomeres in 1998, producing immortalized cell lines. Before this, laboratory cultures of healthy, noncancerous mammalian cells would only divide a fixed number of times, up to the Hayflick limit.

Famous quotes containing the words cells, building and/or blocks:
“They are sworn enemies of lyric poetry.
In prison they accompany the jailer,
Enter cells to hear confessions.
Their short-end comes down
When you least expect it.”
—Charles Simic (b. 1938)
“... what’s been building since the 1980’s is a new kind of social Darwinism that blames poverty and crime and the crisis of our youth on a breakdown of the family. That’s what will last after this flurry on family values.”
—Stephanie Coontz (b. 1944)
“The quest for certainty blocks the search for meaning. Uncertainty is the very condition to impel man to unfold his powers.”
