Hollow Fiber Bioreactor Systems Increase Cell Culture Yield
Holly Ahern | Feb 18, 1990 | 4 min read
One of the most important advances in the field of cell biology came in the early 20th century, with the discovery that plant and animal cells could survive - and even replicate - outside the living organism. In 1907, R.G. Harrison, a neurobiologist trying to prove that nerve fibers were actually outgrowths of single cells, chopped up spinal cord tissue and added it to clotted plasma in a humidified growth chamber. The nerve cells from this crude explant not only grew and divided in this enviro

Whither Cell Biology?

Illustration: A. Canamucio Cell biology has become the third overlapping core discipline of modern biology, along with biochemistry and genetics. Progress over the century--since E.B. Wilson's classic book1 elegantly framed many of the questions of cell biology--has relied on advances in technology and yielded fascinating insights into the ways that cells work. We now have an unprecedented understanding of the structure, organization, and functions of cells. As the number of completed ge

Courtesy of Eric D. Laywell SPHERES OF PROMISE These neurospheres, clusters of cells in culture derived from the CNS of mice, are stained with antibodies against a neuronal protein (red), and a astrocyte protein (green). They have a nuclear counterstain (blue). The brain and spinal cord were once considered mitotic dead ends, a division of neurons dwindling with toddlerhood, with memory and learning the consequence of synaptic plasticity, not new neurons. But the discovery of neural stem

Low levels of the clotting factor HSP47 protect the sleeping giants from blood clots, and the same may be possible for humans and other mammals.
How Groups of Cells Cooperate to Build Organs and Organisms
