Reports from Kyushu University Add New Data to Findings in Tissue Engineering

February 14, 2014



By a News Reporter-Staff News Editor at Angiogenesis Weekly -- Investigators publish new report on Biomedicine and Biomedical Engineering. According to news originating from Fukuoka, Japan, by NewsRx correspondents, research stated, "Tissue engineering requires growth factors, cells and a scaffold to permit effective tissue regeneration. This study aimed to develop a scaffold with a focus on immobilizing growth factors within gelatin."

Our news journalists obtained a quote from the research from Kyushu University, "We focused on the extracellular matrix and developed a heparin-conjugated gelatin (Hep-gela). Conjugation was confirmed using the alcian blue assay and X-ray diffraction patterns. The mechanical strength and stability of the Hep-gela gel in protease solution were improved compared with collagen gel. Hep-gela was able to immobilize vascular endothelial growth factor (VEGF) even in the presence of albumin, with an efficiency of 54.2%. Immobilized VEGF promoted proliferation of human umbilical vein endothelial cells. Hep-gela-immobilized VEGF maintained its native biological activity."

According to the news editors, the research concluded: "In summary, Hep-gela has the potential to become an effective material in the field of regenerative medicine."

The news correspondents report that additional information may be obtained from S. Nakamura, Dept. of Chemical Engineering, Faculty of Engineering, Graduate School, Kyushu University, 744 Motooka, Nishi-ku, Fukuoka 819-0395, Japan. Additional authors for this research include T. Kubo and H. Ijima (see also Biomedicine and Biomedical Engineering).
