Titanium surface coating with a laminin-derived functional peptide promotes bone cell adhesion. BIOMED RESEARCH INTERNATIONAL 2013; 2013:638348. [PMID: 23586052 PMCID: PMC3622367 DOI: 10.1155/2013/638348] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/07/2012] [Revised: 03/04/2013] [Accepted: 03/04/2013] [Indexed: 11/18/2022]
Abstract
Laminin-derived peptide coatings can enhance epithelial cell adhesion to implants, and the positive effect of these peptides on bone cell adhesion has been anticipated. The purpose of this study was to evaluate the improvement in bone cell attachment to and activity on titanium (Ti) scaffolds coated with a laminin-derived functional peptide, Ln2-P3 (the DLTIDDSYWYRI motif). Four Ti disc surfaces were prepared, and a human osteosarcoma (HOS) cell attachment test was performed to select two candidate surfaces for peptide coating. These two candidates were then coated with Ln2-P3 peptide, a scrambled peptide, or left uncoated to measure cell attachment to each surface, following which one surface was chosen to assess alkaline phosphatase (ALP) activity and osteogenic marker gene expression with quantitative real-time PCR. On the commercially pure Ti surface, the Ln2-P3 coating significantly increased cellular ALP activity and the expression levels of ALP and bone sialoprotein mRNA as compared with the scrambled peptide-coated and uncoated surfaces. In conclusion, although further in vivo studies are needed, the findings of this in vitro study indicate that the Ln2-P3-coated implant surface promotes bone cell adhesion, which has clinical implications for reducing the overall treatment time of dental implant therapy.

Abstract
Considerable effort has been directed towards replacing lost teeth using tissue-engineering methods such as titanium implants. A number of studies have tried to modify bioinert titanium surfaces by coating them with functionally bioactive molecules for faster and stronger osseointegration than pure titanium surfaces. Recently, peptides have been recognized as valuable scientific tools in the field of tissue-engineering. The DLTIDDSYWYRI motif of the human laminin-2 α2 chain has been previously reported to promote the attachment of various cell types; however, the in vivo effects of the DLTIDDSYWYRI motif on new bone formation have not yet been studied. To examine whether a laminin-2-derived peptide can promote osseointegration by accelerating new bone formation in vivo, we applied titanium implants coated with the DLTIDDSYWYRI motif in a rabbit tibia model. The application of the DLTIDDSYWYRI motif-treated implant to tibia wounds enhanced collagen deposition and alkaline phosphatase expression. It significantly promoted implant osseointegration compared with treatment with scrambled peptide-treated implants by increasing the bone-to-implant contact ratio and bone area. These findings support the hypothesis that the DLTIDDSYWYRI motif acts as an effective osseointegration accelerator by enhancing new bone formation.

Abstract
BACKGROUND Bone marrow-derived cells (BMCs) have abilities of cell migration and differentiation into tissues/organs in the body and related with the differentiation of teeth or periodontal tissue including fibroblasts. Then, we examined the effect of orthodontic mechanical stress to the transplanted BMC migration into periodontal tissues using BMC transplantation model. MATERIAL AND METHOD BMC from green fluorescence protein (GFP) transgenic mice were transplanted into 8-week-old female C57BL/6 immunocompromised recipient mice, which had undergone 10 Gy of lethal whole-body-irradiation. Five mice as experimental group were received orthodontic mechanical stress using separator between first molar (M1) and second molar (M2) 1 time per week for 5 weeks and 5 mice as control group were not received mechanical stress. The maxilla with M1 and M2 was removed and was immunohistochemically analyzed using a Dako Envision + Kit-K4006 and a primary anti-GFP-polyclonal rabbit antibody. Immunohistochemically stained was defined as positive area and the pixel number of positive area in the periodontal tissue was compared with the previously calculated total pixel number of the periodontal tissue. RESULTS The immunohistochemistry revealed that GFP positive cells were detected in the periodontal tissues, both in the experimental and control specimens. The ratio of pixel number in the examination group showed 5.77 ± 3.24 % (mean ± SD); and that in the control group, 0.71 ± 0.45 % (mean ± SD). The examination group was significantly greater than that of control group (Mann-Whitney U test: p<0.001). CONCLUSION These results suggest that orthodontic mechanical stress accelerates transplanted BMC migration into periodontal tissues.

Abstract
The use of stem cells has opened new prospects for the treatment of orthopaedic conditions characterized by large bone defects. However, many issues still exist to which answers are needed before routine, large-scale application becomes possible. Bone marrow stromal cells (MSC), which are clonogenic, multipotential precursors present in the bone marrow stroma, are generally employed for bone regeneration. Stem cells with multilineage differentiation similar to MSC have also been demonstrated in adipose tissue, peripheral blood, umbilical cord and amniotic fluid. Each source presents its own advantages and drawbacks. Unfortunately, no unique surface antigen is expressed by MSC, and this hampers simple MSC enrichment from heterogeneous populations. MSC are identified through a combination of physical, morphological and functional assays. Different in vitro and in vivo models have been described for the research on bone stem cells. These models should predict the in vivo bone healing capacity of MSC and if the induced osteogenesis is similar to the physiological one. Although stem cells offer an exciting possibility of a renewable source of cells and tissues for replacement, orthopaedic applications often represent case reports whereas controlled randomized trials are still lacking. Further biological aspects of bone stem cells should be elucidated and a general consensus on the best models, protocols and proper use of scaffolds and growth factors should be achieved.

Abstract
Hematopoietic stem cells (HSC) are multi-potent cells that function to generate a lifelong supply of all blood cell types. During mammalian embryogenesis, sites of hematopoiesis change over the course of gestation: from extraembryonic yolk sac and placenta, to embryonic aorta-gonad-mesonephros region, fetal liver, and finally fetal bond marrow where HSC reside postnatally. These tissues provide microenviroments for de novo HSC formation, as well as HSC maturation and expansion. Within adult bone marrow, HSC self-renewal and differentiation are thought to be regulated by two major cellular components within their so-called niche: osteoblasts and vascular endothelial cells. This review focuses on HSC generation within, and migration to, different tissues during development, and also provides a summary of major regulatory factors provided by osteoblasts and vascular endothelial cells within the adult bone marrow niche.

Abstract
This study utilized a full-factorial design to investigate the effect of four factors: presence of whole bone marrow cells, presence of in vitro-generated mineralized extracellular matrix (ECM), presence of dexamethasone, and variations in culture duration, on the proliferation and osteogenic differentiation of mesenchymal stem cells (MSCs) cultured on a polymer scaffold. Electrospun poly(epsilon-caprolactone) (PCL) fiber mesh scaffolds were seeded with rat MSCs and cultured in complete osteogenic medium for 12 days to generate constructs containing mineralized ECM. MSCs or MSCs and whole bone marrow cells were seeded onto decellularized ECM constructs (PCL/ECM) or plain PCL scaffolds and cultured statically for 4, 8, and 16 days in medium either with or without dexamethasone. After each culture period, the cell number was determined by DNA analysis, and the osteogenic differentiation state of the cells was determined by alkaline phosphatase activity and calcium assays. MSCs seeded onto PCL/ECM constructs and cultured in medium either with or without dexamethasone demonstrated similar amounts of calcium deposition after 16 days. A significant increase in cell number over time compared with all other groups was observed when whole bone marrow cells were cocultured with MSCs on PCL scaffolds in medium without dexamethasone. This study establishes that the osteogenic differentiation of MSCs seeded onto ECM-containing constructs is maintained even in the absence of dexamethasone and that the coculture of MSCs and whole bone marrow cells without dexamethasone and ECM enhances the proliferation of a cell population (or populations) present in the whole bone marrow.

Abstract
The use of adult stem cells in tissue engineering approaches will benefit from the establishment of culture conditions that allow the expansion and maintenance of cells with stem cell-like activity and high differentiation potential. In the field of adult stem cells, bone marrow stromal cells (BMSCs) are promising candidates. In the present study, we define, for the first time, conditions for optimizing the yields of cultures enriched for specific progenitors of bone marrow. Using four distinct culture conditions, supernatants from culture of bone fragments, marrow stroma cell line MS-5, embryonic fibroblast cell line NIH3T3, and a cocktail of epidermal growth factor (EGF) and platelet-derived growth factor (PDGF), we isolated four different sub-populations of murine BMSCs (mBMSCs). These cells express a well-known marker of undifferentiated embryonic stem cells (Nanog) and show interesting features in immunophenotype, self-renewal ability, and differentiation potency. In particular, using NIH3T3 conditioned medium, we obtained cells that showed impairment in osteogenic and chondrogenic differentiation while retaining high adipogenic potential during passages. Our results indicate that the choice of the medium used for isolation and expansion of mBMSCs is important for enriching the culture of desired specific progenitors.
