Will new methods that increase blood flow to bone implants improve viability of engineered bone tissue?

23.10.2012
New, advanced techniques are needed that can mimic the normal blood supply that feeds natural bone to improve the viability and success of restorative procedures to replace damaged or diseased bone tissue using engineered constructs.

A comprehensive review article describing the most promising strategies for vascularization of bone tissue substitutes is published in Tissue Engineering, Part B: Reviews, a peer-reviewed journal from Mary Ann Liebert, Inc. The article is available free online on the Tissue Engineering website.

The lack of an adequate blood supply to engineered bone implants has been a major limiting factor in the ability of these large tissue engineered implants to survive and integrate in the body. Many new strategies for stimulating the growth of new blood vessels and the formation of a vascular network to carry nutrients and oxygen and aid in healing are in development, as presented by Lonnissa H. Nguyen, PhD, and coauthors from Massachusetts Institute of Technology (Cambridge); Brigham and Women's Hospital, Harvard University, and Harvard Medical School (MA); Ecole Polytechnique (Palaiseau, France); Chonnam National University (Gwangju, South Korea); Stanford University (CA); Tohoku University (Sendai, Japan). They describe the different methods and their limitations in the article "Vascularized Bone Tissue Engineering: Approaches for Potential Improvement."

"There is a critical need to develop innovative techniques for tissue vascularization, and the work by Nguyen et al. demonstrates both past successes in the field and future avenues for investigation," says Reviews Co-Editor-in-Chief John P. Fisher, PhD, Professor and Associate Chair, Fischell Department of Bioengineering, University of Maryland, College Park, MD.

About the Journal

Tissue Engineering is an authoritative peer-reviewed journal published monthly in print and online in three parts: Part A--the flagship journal; Part B—Reviews; and Part C—Methods. Led by Co-Editors-In-Chief Antonios Mikos, PhD, Louis Calder Professor at Rice University, Houston, TX, and Peter C. Johnson, MD, Vice President, Research and Development, Avery Dennison Medical Solutions of Chicago, IL and President and CEO, Scintellix, LLC, Raleigh, NC, the Journal brings together scientific and medical experts in the fields of biomedical engineering, material science, molecular and cellular biology, and genetic engineering. Tissue Engineering is the official journal of the Tissue Engineering & Regenerative Medicine International Society (TERMIS). Complete tables of content and a sample issue may be viewed online on the Tissue Engineering website.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
