Science Outside the Laboratory

In podcast #12, we talk with two more experts who attended the 2006 Regenerate World Congress in April: policy advisor Dr. David Williams and Ms. Mary Ann Liebert, a publisher.

Dr. Williams is an internationally recognized scientist and a leader in the development of policy and regulations related to regenerative medicine. He leads the United Kingdom Centre for Tissue Engineering (UKCTE), a research collaboration among the University of Manchester and the University of Liverpool. The focus of the UKCTE is to extend the base of scientific knowledge that underpins tissue engineering and to translate this knowledge to the development of commercial products and clinical treatments for healing injured and diseased tissues.

Ms. Liebert is the publisher more than 60 respected books and scientific journals. Founded in 1980, Mary Ann Liebert, Inc. is universally acknowledged for publishing authoritative peer-reviewed journals, books, and trade magazines in the most promising areas of biotechnology, biomedical research/life sciences, clinical medicine and surgery, and law. Such publications not only contribute significantly to the literature but play an active and important role in the advancement of their respective fields.

The First Laboratory-Grown Organ

Dr. Anthony Atala made headlines in April 2006 when he announced that his team had successfully grown new bladders for seven patients with spina bifida, a condition in which the spinal column fails to completely close during fetal development. While healthy bladders maintain a reasonably low pressure as they fill with urine, the bladders of some spina bifida patients generate dangerously high pressures, causing kidney damage.

Dr. Atala’s tissue engineered bladders are made of a patient’s own cells grown on a custom mold designed to specifications provided by detailed CT scans of the patient’s pelvis. In podcast #11, you’ll hear Dr. Atala tell this fascinating story of innovation, along with some insight into how the field of regenerative medicine comes together as a community to work on challenges like creating whole organs from cells.

Anthony Atala, MD, is director of the Wake Forest Institute for Regenerative Medicine and chairman of the Department of Urology at the Wake Forest University School of Medicine. For more information about Dr. Atala’s work, see the institute’s web page.

Each year, approximately 200,000 persons in the United States suffer tears of their anterior cruciate ligament (ACL). Approximately 2/3 of those tears require surgical reconstruction (1/3 at the time of injury and 1/3 at a later time).

While orthopaedic surgeons are on the front line to repair tears of the ACL, Dr. Savio Woo and his team at the Muscular Skeletal Research Center (MSRC) are the important partners to the surgeons, developing a fundamental understanding of the function of the ACL and the other components of the knee. Through the eyes of the biomedical engineer, the MSRC is developing a better understanding of the function of the ligaments and the MSRC has identified ways to optimize surgical procedures, and enhance successful outcomes.

As you’ll hear in podcast #9, Dr. Woo and his multidisciplinary team makes use of robotics to understand the role of the ACL and the other components of the knee. They are also investigating the use of tissue engineered scaffolds to facilitate the repair of torn ACLs. The attached graphic amplifies on the research strategies and focus areas of the MSRC. To learn more about the work of Dr. Woo and his colleagues, see the MSRC web site.

Savio L-Y. Woo, PhD, DSc is the W.K. Whiteford Professor, Department of Bioengineering, and Professor-Mechanical Engineering, and Professor-Rehabilitation Science & Technology, University of Pittsburgh. Dr. Woo is also Vice Chairman for Research, Mentorship/Internship Program, Department of Bioengineering.

Dr. Woo is a recipient of an Olympic Gold Metal in recognition of his untiring contributions to the science of sports medicine. As Dr. Woo details in the podcast, he and his wife have established the “Asian and American Institute for Education and Research” (ASIAM).

You can’t make a working synthetic tissue or joint until you fully understand how a natural one functions. That’s the mantra of Dr. Van Mow, who has led the field of tissue engineering decades, and a co-creator of the generalized theory of classical mechanics, which makes it possible to calculate the mechanical loads acting on our bodies as we perform everyday tasks.

As you’ll hear in podcast #8, Dr. Mow is now examining laboratory-made tissues to see if they can function as natural tissues do. If not, it’s back to the drawing board: Thanks to Dr. Mow’s guidance, regenerative medicine researchers are concentrating on doing work right, rather than first. He’s helped to bring the field through the overly-speculative 1990s, a time of what he calls “irrational exuberance,” to the nose-to-the-grindstone present, what Dr. Mow calls the era of “functional tissue engineering.”

Van C. Mow, PhD is the Stanley Dicker Professor of Biomedical Engineering and Orthopaedic Bioengineering, and Chairman of the Department of Biomedical Engineering at Columbia University.

The citation for the pivotal manuscript that Dr. Mow references in his discussion is:

Fung, Y.C.: Biomechanics: it’s scope, history, and some problems of continuum mechanics in physiology. Appl. Mech. Rev., 21: 1-20, 1968.
