From stem cells to organs: The bioengineering challenge

18.02.2008
For more than a decade, Peter Zandstra has been working at the University of Toronto to rev up the production of stem cells and their descendants. The raw materials are adult blood stem cells and embryonic stem cells. The end products are blood and heart cells – lots of them. Enough mouse heart cells that they form beating tissue.

To do this, he has been applying engineering principles to stem cell research – work that has just earned him recognition by the American Association for the Advancement of Science (AAAS). The society will induct him as a Fellow during its Annual Conference, being held in Boston from February 14 to 18.

Starting with computer models of stem cell growth and differentiation (the process by which a stem cell matures into its final form), Zandstra has moved on to develop more sophisticated culture methods that fine-tune the microenvironments to guide the generation of the different cells types that make up the mature cells in our tissues: heart cells for the heart or blood cells for blood.

"If you describe something mathematically, you have a much better understanding of it than if you just observe it," he says. "And it's also a powerful way to test many different hypotheses in silico before going into the lab and doing the much more difficult experiments in vitro."

Dr. Zandstra, the Canada Research Chair in Stem Cell Bioengineering, also held a prestigious NSERC Steacie Fellowship. The Steacie prize - which goes to six select Canadian professors annually – allowed Zandstra to extend his work from mouse to man.

“There's only so much we can do with mouse cells,” notes Dr. Zandstra. “Now if we can also figure out how to get human embryonic stem cells to differentiate on command to generate functional adult-like cells, you can begin to think about the kinds of medical conditions you could treat with them.”

Im Focus: Unraveling the nature of 'whistlers' from space in the lab

A new study sheds light on how ultralow frequency radio waves and plasmas interact

Scientists at the University of California, Los Angeles present new research on a curious cosmic phenomenon known as "whistlers" -- very low frequency packets...

Im Focus: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
