Cell-derived extracellular matrix (ECM) scaffolds have received considerable interest for tissue engineering applications. In this study, ECM scaffolds derived from mesenchymal stem cell (MSC), chondrocyte, and fibroblast were prepared by culturing cells in a selectively removable poly(lactic-co-glycolic acid) (PLGA) template. These three types of ECM(More)
Ideal biomaterials for bone tissue engineering should have the capability to guide the osteogenic differentiation of mesenchymal stem cells and, at the same time, to stimulate angiogenesis of endothelia cells. In this study it was found that three Ca-Mg-Si-containing bioceramics (bredigite Ca7MgSi4O16, akermanite Ca2MgSi2O7 and diopside CaMgSi2O6) had(More)
In skin tissue engineering, a three-dimensional porous scaffold is necessary to support cell adhesion and proliferation and to guide cells moving into the repair area in the wound healing process. Structurally, the porous scaffold should have an open and interconnected porous architecture to facilitate homogenous cell distribution. Moreover, the scaffolds(More)
Development of autologous scaffolds has been highly desired for implantation without eliciting adverse inflammatory and immune responses. However, it has been difficult to obtain autologous scaffolds by tissue decellularization because of the restricted availability of autologous donor tissues from a patient. Here we report a method to prepare autologous(More)
The effects of hardystonite (Ca(2)ZnSi(2)O(7), CSZn) and tricalcium phosphate (beta-TCP) on the proliferation and osteogenic differentiation of human bone marrow-derived mesenchymal stem cells (MSCs) were compared by directly culturing MSCs on ceramic disks (contact mode) or separately culturing cells with ceramic disks (non-contact mode). In non-contact(More)
The capacity to induce rapid vascular ingrowth during new bone formation is an important feature of biomaterials that are to be used for bone regeneration. Akermanite, a Ca-, Mg- and Si-containing bioceramic, has been demonstrated to be osteoinductive and to promote bone repair. This study further demonstrates the ability of akermanite to promote(More)
IMPORTANCE OF THE FIELD Biomimetic scaffolds and substrates of extracellular matrices (ECMs) play an important role in the regulation of cell function and in the guidance of new tissue regeneration, as an ECM has the intrinsic cues necessary to communicate with and dictate to cells.

Loss of cartilaginous phenotype during in vitro expansion culture of chondrocytes is a major barrier to the application of chondrocytes for tissue engineering. In previous study, we showed that dedifferentiation of chondrocytes during the passage culture was delayed by matrices formed by primary chondrocytes (P0-ECM). In this study, we investigated bovine(More)
The loss of cartilaginous phenotype during in vitro expansion culture of chondrocytes is a major barrier for the application of cartilage tissue engineering. The use of matrices mimicking the in vivo extracellular matrix (ECM) microenvironment is anticipated to be an efficient method to suppress chondrocyte phenotype loss. In this study, we developed(More)
