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.

“There is something about the literary life that repels me, all this desperate building of castles on cobwebs, the long-drawn acrimonious struggle to make something important which we all know will be gone forever in a few years, the miasma of failure which is to me almost as offensive as the cheap gaudiness of popular success.”
—Raymond Chandler (1888–1959)
“The vast silence of Buddha overtakes
