Cell & Tissue Culture
A new device allows perfusion of bioengineered structures built from smaller pieces of tissue prepared in the lab. It is a first step toward someday building whole organs
Problem: Scientists must typically rely on high-end cell sorters in core facilities to run their samples. These cell sorters—equipped with five or more lasers and double digit detection channels—were originally utilized to answer pressing questions arising in the immunology field. However, they are overly complex for the new breed of user who sorts cells today: cell biologists and biochemists who employ fluorescent proteins and require at most four colors and one-to-two population sorting. The challenge is that as demand increases, the number of staff available to operate these complex instruments remains the same. As a result, wait times at core facilities have ballooned, literally putting research on hold until capacity is available. For the more than half of today’s cell sorting users who require four colors or
fewer sorts, the elaborate equipment is becoming a bottleneck.
A novel jelly-like substance developed by Kansas State University researchers was recently issued a U.S. patent. The substance may be used for biomedical applications, ranging from cell culture and drug delivery to repairing and replacing tissue, organs and cartilage.
Many studies suggest that toxins in the environment may be a cause of autism, affecting a mother’s unborn child as it develops. However, proving this for certain is difficult, as it is something that cannot be tested directly.
How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not only understand the origin of life - we can also revolutionize the future of technology.
Geoffrey Bartholomeusz, PhD, associate professor in the Department of Experimental Therapeutics and director of the siRNA Core Facility at the University of Texas MD Anderson Cancer Center, talks to contributing editor Tanuja Koppal, PhD, about why there is a growing interest in replacing some 2D cell culture applications with 3D cell cultures. He talks about where and why he uses 3D-based cell cultures in his lab and what lab managers should take into consideration before making the investment in this innovative technology.
For years, researchers and patients have hoped that embryonic stem cells (ESCs)—capable of forming nearly any cell type in the body—could provide insight into numerous diseases perhaps even be used to treat them. Yet progress has been hampered by the inability to transfer research and tools from mouse ESC studies to their human counterparts, in part because human ESCs are “primed” and slightly less plastic than the mouse cells.
Engineering breakthrough will allow cancer researchers to create live tumors with a 3D printer
Scientists reported yesterday (Apr. 10) the first human recipients of laboratory-grown vaginal organs. A research team led by Anthony Atala, M.D., director of Wake Forest Baptist Medical Center’s Institute for Regenerative Medicine, describes in the Lancet long-term success in four teenage girls who received vaginal organs that were engineered with their own cells.
