Microsphere as a cell scaffold in bone tissue engineering / 中国组织工程研究

ABSTRACT

A major challenge in bone tissue engineering is to amplify cell numbers with maintaining the desired phenotype. As a crucial element in bone tissue engineering,the field of scaffold is in the forefront of developments. Due to superiority in both cell expansion and conveyance,the approach of microspherical scaffold has latterly been adopted as the substrate of cell propagation,carrier of expanded cells,as well as scaffold of regenerated bone tissue. Combined with injectable matrices after cell encapsulation or attachment,the microsphere-based system provides an attractive method for highly efficient cell amplification and minimally invasive cell delivery for bone tissue engineering.
