BACKGROUND Bone marrow-derived mesenchymal stem cells (BMSCs) are a widely researched adult stem cell population capable of differentiation into various lineages. Because many promising applications of tissue engineering require cell expansion following harvest and involve the treatment of diseases and conditions found in an aging population, the effect of(More)
Skin engineering provides a new strategy for treating a wide variety of skin defects. In particular, electrospun nanofibrous membranes have been used as carriers for epidermis engineering. The aim of this study was to investigate the feasibility of a modified gelatin and polycaprolactone (GT/PCL) electrospun membrane for epidermis engineering. The(More)
Mesenchymal stem cells (MSCs) are known to have the potential for articular cartilage regeneration, and are suggested for the treatment of osteoarthritis (OA). Here, we investigated whether intra-articular injection of xenogeneic human adipose-derived mesenchymal progenitor cells (haMPCs) promoted articular cartilage repair in rabbit OA model and engrafted(More)
Endothelial progenitor cells (EPCs) from bone marrow have proven to be functional for the prevention of liver fibrosis in chronic liver injury. However, expansion of EPCs in culture is complicated and expansive. Previously, we have established a simple method that could enrich and expand EPCs by simple seeding bone marrow cells in high density dots. The(More)
Due to lack of optimal inductive protocols, how to effectively improve chondrogenesis of adiposederived stem cells (ASCs) is still a great challenge. Our previous studies demonstrated that the culture media derived from chondrocyte-scaffold constructs (conditional media) contained various soluble chondrogenic factors and were effective for directing(More)
In vitro expansion of endothelial progenitor cells (EPCs) remains a challenge in stem cell research and its application. We hypothesize that high density culture is able to expand EPCs from bone marrow by mimicking cell-cell interactions of the bone marrow niche. To test the hypothesis, rat bone marrow cells were either cultured in high density (2 × 10(5)(More)

Both cultured Bone Marrow Mesenchymal Stem Cells (BMSCs) and non-cultured Bone Marrow Mononuclear Cells (BM-MNCs) can improve random-pattern skin flap survival. However, whether prior culture expansion of bone marrow cells is beneficial for this therapy remains unclear. In the current study, the protective effects of BM-MNCs and BMSCs derived from identical(More)
Acellular corneal stroma matrix has been used for corneal stroma engineering. However, because of its compact tissue structure, regrowth of keratocytes into the scaffold is difficult. Previously, we developed a sandwich model for cartilage engineering using acellular cartilage sheets. In the present study, we tested this model for corneal stroma(More)
Tissue engineering approach provides a hopeful strategy for reconstructing testis testosterone-secreting functions. However, limited source and low proliferative activity in vitro of Leydig cells (LCs, the main testosteroneproducing cells) makes testis-like tissue regeneration difficult to be achieved. This study explored the feasibility of in vitro(More)
