Porous alginate/hydroxyapatite scaffolds developed for bone tissue engineering

Published in Blood Weekly, December 30th, 2004

Porous alginate/hydroxyapatite scaffolds were developed for bone tissue engineering.

"In this study a series of alginate/hydroxyapatite (HAP) composite scaffolds was prepared by phase separation. HAP was incorporated into the alginate gel solution to improve both the mechanical and cell-attachment properties of the scaffolds.

"These scaffolds had a well-interconnected porous structure with an average pore size of 150 mcm and over 82% porosity," researchers in Taiwan report.

"The alginate/HAP scaffold prepared at -40degreesC with a 50% HAP content showed the best mechanical properties. The morphology of scaffolds could be...
