Progress to Engineered Organs
From
The research, published online in the Proceedings of the National Academy of Sciences, sheds light on the mechanics of cell, tissue and organ formation. The research revealed basic mechanisms about how a group of bacterial cells can form large three-dimensional structures.
“If you want to create an organism, the geometry of how a group of cells self-organizes is crucial,” said Dr. Hongbing Lu, professor of mechanical engineering and holder of the Louis Beecherl Jr. Chair at UT Dallas and an author of the study. “We found that cell death leads to wrinkles, and the stiffer the cell the fewer wrinkles.”
Organ formation is the result of individual cells teaming with others. The aggregate of the cells and their environment form a thin layer of what is known as a biofilm. These biofilms form 3-D wrinkled patterns.
Wrinkle formation that occurred on a four-day-old subtilis biofilm was preceded by cell death.
