Abstract
Oral and maxillofacial bone defects severely impair appearance and function, and bioactive materials are urgently needed for bone regeneration. Here, we spheroid co-cultured green fluorescent protein (GFP)-labeled bone marrow stromal cells (BMSCs) and osteocyte-like MLO-Y4 cells in different ratios (3:1, 2:1, 1:1, 1:2, 1:3) or as monoculture. Bone-like tissue was formed in the 3:1, 2:1, and 1:1 co-cultures and MLO-Y4 monoculture. We found a continuous dense calcium phosphate structure and spherical calcium phosphate similar to mouse femur with the 3:1, 2:1, and 1:1 co-cultures, along with GFP-positive osteocyte-like cells encircled by an osteoid-like matrix similar to cortical bone. Flake-like calcium phosphate, which is more mature than spherical calcium phosphate, was found with the 3:1 and 2:1 co-cultures. Phosphorus and calcium signals were highest with 3:1 co-culture, and this bone-like tissue was ring-shaped. In a murine tooth extraction model, implantation of the ring-shaped bone-like tissue yielded more bone mass, osteoid and mineralized bone, and collagen versus no implantation. This tissue fabricated by spheroid co-culturing BMSCs with osteocytes yields an internal structure and mineral composition similar to mouse femur and could promote bone formation and maturation, accelerating regeneration. These findings open the way to new strategies in bone tissue engineering.

Abstract
BACKGROUND The goal of this study was to create a biomaterial which combines concentrated growth factor (CGF) with an adipose-derived stem cell (ADSC) sheet to promote the repair of skull defects in rats. METHODS We determined the optimal concentration of CGF extract by investigating the effects of different concentrations (0, 5%, 10%, and 20%) on the proliferation and differentiation of ADSCs. Then we created a complex combining CGF with an ADSC sheet, and tested the effects on bone repair in four experimental rat groups: (A) control; (B) ADSC sheet; (C) CGF particles; (D) combination of CGF + ADSCs. Eight weeks after the procedure, osteogenesis was assessed by micro-CT and hematoxylin and eosin staining. RESULTS We found that the concentration of CGF extract that promoted optimal ADSC proliferation and differentiation in vitro was 20%. In turn, bone regeneration was promoted the most by the combination of CGF and ADSCs. CONCLUSION In this study, we determined the optimal ratio of CGF and ADSCs to be used in a biomaterial for bone regeneration. The resulting CGF/ADSCs complex promotes maxillofacial bone defect repair in rats.

Abstract
Cell sheets from bone marrow mesenchymal stem cells (BMSC) have been widely used in the field of bone tissue engineering, although their source remains a challenging issue. In this study, adipose-derived stem cells (ADSC) were induced to differentiate into osteoblasts, and the incorporation of coral scaffolds with ADSC sheets for bone formation at an ectopic site was also investigated. First, ADSC isolated from inguinal adipose tissue of New Zealand rabbits were cultured for two weeks without passaging under osteogenic induction, and the microstructures of cell sheets were analysed by histological and scanning electron microscope (EM) observation. In addition, the activity of alkaline phosphatase (ALP) and alizarin red staining was also measured to detect their osteogenic ability. Subsequently, ADSC were proved to be able to proliferate well when seeded on the coral scaffolds. Next, coral scaffolds were wrapped in cell sheets to prepare sheet-coral complexes, which were implanted into subcutaneous pockets in nude mice. At eight weeks after implantation, gross examination, microcomputed tomography (MicroCT), and histological analysis were investigated to assess new bone formation. MicroCT scanning and histological analysis showed that there was more highly dense tissue formed in the complex group than control group (p=0.0004). These results indicated that osteoblastic ADSC sheets could be used to construct engineered bone and the incorporation of coral scaffolds with ADSC sheets significantly improved bone formation, providing a newly approach for bone tissue engineering.

Abstract
Cell sheet techniques are widely used in bone engineering. However, vascularization remains a challenge in fabricating vascularized engineered bone. The goal of this study was to induce adipose-derived stem cell (ADSC) osteogenic and angiogenic lineage differentiation and investigate the use of bidiretionally differentiated ADSCs for bone regeneration. ADSCs were cultured to form an osteogenic cell sheet. Other ADSCs were induced to differentiate into endothelial progenitor cells (EPCs), which were identified and characterized by morphological observation and CD31 immunofluorescent staining. Then, the ADSC sheet-EPC complexes were implanted subcutaneously into nude mice, while ADSC sheets alone were implanted as a control. After 8 weeks of transplantation, microcomputed tomography (micro-CT) and histological observation were used to assess bone formation. We then implanted the complexes in calvarial defects in rabbits and assessed bone repair by micro-CT and histological analysis. The ADSC sheets consisted of multiple layers of cells and extracellular matrix. The obtained EPCs formed capillary-like structures and expressed the specific antigen marker CD31. The osteogenic ADSC sheet-EPC complexes formed dense and well-vascularized new bone tissue at 8 weeks after implantation. Bone density was significantly lower in the control group than in the complex group (p < .05). In addition, the reconstruction of calvarial defects in rabbits in complex group was obviously greater than that in the control group (p < .05). These results suggested that the approach of engineering bone tissue with bidiretionally differentiated ADSCs enabled bone regeneration, thus offering a promising strategy for repairing bone defects.

Abstract
Mesenchymal stem cells (MSCs) are previously found to have potential capacity to differentiate into osteocytes when exposed to specific stimuli. However, the detailed molecular mechanism during this progress remains largely unknown. In the current study, we characterized the lncRNA NKILA as a crucial positive regulator for osteogenesis of MSCs. NKILA attenuation significantly inhibits the calcium deposition and alkaline phosphatase activity of MSCs. More interestingly, we defined that NKILA is functionally involved in the regulation of RXFP1/PI3K‐AKT and NF‐κB signalling. Knockdown of NKILA dramatically down‐regulates the expression of RXFP1 and then reduces the activity of AKT, a downstream regulator of RXFP1 signalling which is widely accepted as an activator of osteogenesis. Moreover, we identify NF‐κB as another critical regulator implicated in NKILA‐mediated osteogenic differentiation. Inhibition of NF‐κB can induce the expression of RUNX2, a master transcription factor of osteogenesis, in a HDAC2‐mediated deacetylation manner. Thus, this study illustrates the regulatory function of NKILA in osteogenesis through distinct signalling pathways, therefore providing a new insight into searching for new molecular targets for bone tissue repair and regeneration.

Abstract
Mesenchymal stem cells (MSCs) have been used in therapies for bone tissue healing. The aim of this study was to investigate the effect of cell source and osteoblast differentiation on gene expression profiles of MSCs from bone marrow (BM-MSCs) or adipose tissue (AT-MSCs) to contribute for selecting a suitable cell population to be used in cell-based strategies for bone regeneration. BM-MSCs and AT-MSCs were cultured in growth medium to keep MSCs characteristics or in osteogenic medium to induce osteoblast differentiation (BM-OBs and AT-OBs). The transcriptomic analysis was performed by microarray covering the entire rat functional genome. It was observed that cells from bone marrow presented higher expression of genes related to osteogenesis, whereas cells from adipose tissue showed a higher expression of genes related to angiogenesis and adipocyte differentiation, irrespective of cell differentiation. By comparing cells from the same source, MSCs from both sources exhibited higher expression of genes involved in angiogenesis, osteoblast differentiation, and bone morphogenesis than osteoblasts. The clustering analysis showed that AT-OBs exhibited a gene expression profile closer to MSCs from both sources than BM-OBs, suggesting that BM-OBs were in a more advanced stage of differentiation. In conclusion, our results suggest that in cell-based therapies for bone regeneration AT-MSCs could be considered for angiogenic purposes, whereas BM-MSCs and osteoblasts differentiated from either source could be better for osteogenic approaches.

Abstract
Adipose tissue-derived stem cells (ASCs) are known to be able to promote repair of injured tissue via paracrine factors. However, the effect of cell density and inflammatory cytokines on the paracrine ability of ASCs remains largely unknown. To investigate these effects, ASCs were cultured in 8000 cells/cm2, 20,000 cells/cm2, 50,000 cells/cm2, and 400,000 cells/cm2 with and without 10 or 20 ng/ml tumor necrosis factor alpha (TNFα) and 25 or 50 ng/ml interferon gamma (IFNγ). ASC-sheets formed at 400,000 cells/cm2 after 48 h of culture. With increasing concentrations of TNFα and IFNγ, ASC-sheets with 400,000 cells/cm2 had increased production of angiogenic factors Vascular Endothelial Growth Factor and Fibroblast Growth Factor and decreased expression of pro-inflammatory genes TNFA and Prostaglandin Synthase 2 (PTGS2) compared to lower density ASCs. Moreover, the conditioned medium of ASC-sheets with 400,000 cells/cm2 stimulated with the low concentration of TNFα and IFNγ enhanced endothelial cell proliferation and fibroblast migration. These results suggest that a high cell density enhances ASC paracrine function might beneficial for wound repair, especially in pro-inflammatory conditions.

Abstract
Mesenchymal stem cells (MSCs) are heterogeneous cell populations that serve as reserves for tissue regeneration in the presence of disease or injury. Although MSCs are found in various tissues, bone marrow-derived stem/stromal cells (BMSCs) and adipose tissue-derived stem/stromal cells (ADSCs) have been most thoroughly investigated. Furthermore, ADSCs have recently emerged as an attractive source of MSCs due to their abundance and availability. BMSCs and ADSCs demonstrate similar morphological characteristics, but their in vitro characteristics and differentiation abilities appear to differ. In this review, the author summarizes and compares current knowledge on BMSCs and ADSCs with particular emphasis on in vitro expansion and osteogenic/angiogenic potential, and reviews knowledge of their synergistic effects when co-applied. © 2017 Wiley Periodicals, Inc.
