Abstract
Bone regeneration is a complex, well-orchestrated process based on the interactions between osteogenesis and angiogenesis, observed in both physiological and pathological situations. However, specific conditions (e.g., bone regeneration in large quantity, immunocompromised regenerative process) require additional support. Tissue engineering offers novel strategies. Bone regeneration requires a cell source, a matrix, growth factors and mechanical stimulation. Regenerative cells, endowed with proliferation and differentiation capacities, aim to recover, maintain, and improve bone functions. Vascularization is mandatory for bone formation, skeletal development, and different osseointegration processes. The latter delivers nutrients, growth factors, oxygen, minerals, etc. The development of mesenchymal stromal cells (MSCs) and endothelial progenitor cells (EPCs) cocultures has shown synergy between the two cell populations. The phenomena of osteogenesis and angiogenesis are intimately intertwined. Thus, cells of the endothelial line indirectly foster osteogenesis, and conversely, MSCs promote angiogenesis through different interaction mechanisms. In addition, various studies have highlighted the importance of the microenvironment via the release of extracellular vesicles (EVs). These EVs stimulate bone regeneration and angiogenesis. In this review, we describe (1) the phenomenon of bone regeneration by different sources of MSCs. We assess (2) the input of EPCs in coculture in bone regeneration and describe their contribution to the osteogenic potential of MSCs. We discuss (3) the interaction mechanisms between MSCs and EPCs in the context of osteogenesis: direct or indirect contact, production of growth factors, and the importance of the microenvironment via the release of EVs.

Abstract
Vascularization is a prerequisite for bone formation. Endothelial progenitor cells (EPCs) stimulate bone formation by creating a vascular network. Moreover, EPCs secrete various bioactive molecules that may regulate bone formation. The aim of this research was to shed light on the pathways of EPCs in bone formation. In a subcutaneous nude mouse ectopic bone model, the transplantation of human EPCs onto β-TCP scaffold increased angiogenesis (p < 0.001) and mineralization (p < 0.01), compared to human neonatal dermal fibroblasts (HNDF group) and a-cellular scaffold transplantation (β-TCP group). Human EPCs were lining blood vessels lumen; however, the majority of the vessels originated from endogenous mouse endothelial cells at a higher level in the EPC group (p < 01). Ectopic mineralization was mostly found in the EPCs group, and can be attributed to the recruitment of endogenous mesenchymal cells ten days after transplantation (p < 0.0001). Stromal derived factor-1 gene was expressed at high levels in EPCs and controlled the migration of mesenchymal and endothelial cells towards EPC conditioned medium in vitro. Blocking SDF-1 receptors on both cells abolished cell migration. In conclusion, EPCs contribute to osteogenesis mainly by the secretion of SDF-1, that stimulates homing of endothelial and mesenchymal cells. This data may be used to accelerate bone formation in the future.

Abstract
OBJECTIVES Reconstruction of long segmental bone defects is demanding for patients and surgeons, and associated with long-term treatment periods and substantial complication rates in addition to high costs. While defects up to 4-5 cm length might be filled up with autologous bone graft, heterologous bone from cadavers, or artificial bone graft substitutes, current options to reconstruct bone defects greater than 5 cm consist of either vascularized free bone transfers, the Masquelet technique or the Ilizarov distraction osteogenesis. Alternatively, autologous cell transplantation is an encouraging treatment option for large bone defects as it eliminates problems such as limited autologous bone availability, allogenic bone immunogenicity, and donor-site morbidity, and might be used for stabilizing loose alloplastic implants. METHODS The authors show different cell therapies without expansion in culture, with ex vivo expansion and cell therapy in local bone defects, bone healing and osteonecrosis. Different kinds of cells and scaffolds investigated in our group as well as in vivo transfer studies and BMC used in clinical phase I and IIa clinical trials of our group are shown. RESULTS Our research history demonstrated the great potential of various stem cell species to support bone defect healing. It was clearly shown that the combination of different cell types is superior to approaches using single cell types. We further demonstrate that it is feasible to translate preclinically developed protocols from in vitro to in vivo experiments and follow positive convincing results into a clinical setting to use autologous stem cells to support bone healing.

Abstract
INTRODUCTION Meanwhile, the osteoconductive properties of frequently used synthetic bone grafts can be improved by the use of osteoinductive cells and growth factors. Nevertheless, the cultivation of endothelial progenitor cells (EPC) seems to be difficult and requires a pre-conditioning of the scaffolds with fibronectin. Additionally, the influence of the scaffolds' design on cell cultivation is not fully elucidated. METHODS As scaffold, a commercially available β-tricalcium phosphate was used. 5 × 105 EPC, or 5 × 105 MSC or a combination of each 2.5 × 105 cells was seeded onto the granules. We investigated seeding efficiency, cell morphology, cell metabolism, adherence, apoptosis and gene expression of EPC and MSC in this in vitro study on days 2, 6 and 10. RESULTS Total number of adherent cells was higher on the β-TCP without fibronectin coating. The number of cells in all approaches significantly declined when a solid β-TCP was used. Metabolic activity of MSC was comparable throughout the scaffolds and increased until day 10. Additionally, the amount of supernatants VEGF was higher for MSC than for EPC. DISCUSSION Our results demonstrate that a coating of the scaffold for successful cultivation of EPC in vitro is not necessary. Furthermore, our study showed that structural differences of the scaffolds significantly influenced cell adherence and metabolic activity. Thereby, the influence on EPC seems to be higher than on MSC.

Abstract
Mesenchymal stem cells (MSCs) are multipotent cells capable of differentiating into multiple cell lineages and contributing to tissue repair and regeneration. Characterization of the physiological function of MSCs has been largely hampered by lack of unique markers. Nestin, originally found in neuroepithelial stem cells, is an intermediate filament protein expressed in the early stages of development. Increasing studies have shown a particular association between Nestin and MSCs. Nestin could characterize a subset of bone marrow perivascular MSCs which contributed to bone development and closely contacted with hematopoietic stem cells (HSCs). Nestin expressing (Nes(+)) MSCs also play a role in the progression of various diseases. However, Nes(+) cells were reported to participate in angiogenesis as MSCs or endothelial progenitor cells (EPCs) in several tissues and be a heterogeneous population comprising mesenchymal cells and endothelial cells in the developing bone marrow. In this review article, we will summarize the progress of the research on Nestin, particularly the function of Nes(+) cells in bone marrow, and discuss the feasibility of using Nestin as a specific marker for MSCs.

Abstract
UNLABELLED QUESTION/AIM: Cell-based therapy by cultivated stem cells (mesenchymal stem cells [MSC] and endothelial progenitor cells [EPC]) in a large-sized bone defect has already shown improved vascularization and new bone formation. However, these methods are clinically afflicted with disadvantages. Another heterogeneous bone marrow cell population, the so-called human bone marrow-derived mononuclear cells (BMC), has nevertheless been used clinically and showed improved vascularization in ischemic limbs or in the myocardium. For clinical use, a certified process has been established; thus, BMC were isolated from bone marrow aspirate by density gradient centrifugation, washed, cleaned, and given back to patients within several hours. This investigation tested the ability of human BMC seeded on beta-tricalcium phosphate (β-TCP) and placed into a large bone defect in rats to improve the bone healing process in vivo. METHODS Human EPC were isolated from buffy coat, and MSC or BMC, respectively, were isolated from bone marrow aspirate by density gradient centrifugation. 1.0×10(6) cells were loaded onto 750 μL β-TCP (0.7-1.4 mm). Large femoral defects (6 mm) in athymic rats were created surgically and stabilized with an internal fixateur. The remaining defects were filled with β-TCP granules alone (group 1), β-TCP+EPC/MSC (group 2), or β-TCP+BMC (group 3). After 8 weeks, histomorphometric analysis (new bone formation), radiological microcomputer tomography analysis (bony bridging), and biomechanical testing (three-point bending) were achieved. Moreover, a tumorigenicity study was performed to evaluate the safety of BMC implantation after 26 weeks. For statistical analysis, the Kruskal-Wallis test was used. RESULTS Eight weeks after implantation of EPC/MSC or BMC, respectively, we detected a more significant new bone formation compared to control. In group 2 and 3, bony bridging of the defect was seen. In the control group, more chondrocytes and osteoid were detected. In the BMC and EPC/MSC group, respectively, less chondrocytes and a significantly more advanced bone formation were observed. The biomechanical stability of the bone regenerate was significantly enhanced if BMC and EPC/MSC, respectively, were implanted compared to control. Moreover, no tumor formation was detected either macroscopically or histologically after 26 weeks of BMC implantation. DISCUSSION Implanted BMC suggest that a heterogeneous cell population may provide a powerful cellular therapeutic strategy for bone healing in a large bone defect in humans.

Abstract
Bone regeneration is a well organized but complex physiological process, in which different cell types and their activated signaling pathways are involved. In bone regeneration and remodeling processes, mesenchymal stem cells (MSCs) have a crucial role, and their differentiation during these processes is regulated by specific signaling molecules (growth factors/cytokines and hormones) and their activated intracellular networks. Especially the utilization of the molecular machinery seems crucial to consider prior to developing bone implants, bone-substitute materials, and cell-based constructs for bone regeneration. The aim of this review is to provide an overview of the signaling mechanisms involved in bone regeneration and remodeling and the osteogenic potential of MSCs to become a key cellular resource for such regeneration and remodeling processes. Additionally, an overview of possibilities to beneficially exploit cell signaling processes to optimize bone regeneration is provided.

Abstract
Early vascularization is a prerequisite for successful bone healing and endothelial progenitor cells (EPC), seeded on appropriate biomaterials, can improve vascularization. The type of biomaterial influences EPC function with bioglass evoking a vascularizing response. In this study the influence of a composite biomaterial based on polylactic acid (PLA) and either 20 or 40% bioglass, BG20 and BG40, respectively, on the differentiation and survival of EPCs in vitro was investigated. Subsequently, the effect of the composite material on early vascularization in a rat calvarial critical size defect model with or without EPCs was evaluated. Human EPCs were cultured with β-TCP, PLA, BG20 or BG40, and seeding efficacy, cell viability, cell morphology and apoptosis were analysed in vitro. BG40 released the most calcium, and improved endothelial differentiation and vitality best. This effect was mimicked by adding an equivalent amount of calcium to the medium and was diminished in the presence of the calcium chelator, EGTA. To analyze the effect of BG40 and EPCs in vivo, a 6-mm diameter critical size calvarial defect was created in rats (n = 12). Controls (n = 6) received BG40 and the treatment group (n = 6) received BG40 seeded with 5×105 rat EPCs. Vascularization after 1 week was significantly improved when EPCs were seeded onto BG40, compared to implanting BG40 alone. This indicates that Ca2+ release improves EPC differentiation and is useful for enhanced early vascularization in critical size bone defects.
