Rabbit bone marrow cells were cultured in diffusion chambers with or without decalcified bone matrix. The chambers were assayed after 28 days for alkaline phosphatase activity, deoxyribonucleic acid (DNA), calcium, and phosphorus contents. Morphologically, marrow cells incubated with or without matrix differentiated to form bone and cartilage. With bone matrix, the calcium and phosphorus contents of chambers were significantly higher than control chambers. Alkaline phosphatase activity and DNA content were not influenced by inclusion of bone matrix. These results indicate that bone matrix constituents exert a stimulatory effect on bone formation from marrow cells. This osteogenic stimulation could be due to the influence of an osteoinductive factor and/or to stimulation of osteoprogenitor cells known to be present in the marrow.

The global autologous matrix-induced chondrogenesis market has five major regional segments that divide it in terms of geography. These regions are North America, Europe, Asia Pacific, Middle East and Africa, and Latin America. Currently, the autologous matrix-induced chondrogenesis market is globally dominated by the regional segment of North America. The region is expected to continue to be a leading contributor for the given period of forecast of 2018 to 2028. There are multiple factors that are responsible for the development of the global autologous matrix-induced chondrogenesis market. Some of the important driving factors for market growth are growing geriatric population and increasing sports-related injuries in the region.. On the other hand, the regional segment of Asia Pacific is projected to be the fastest developing region of the global autologous matrix-induced chondrogenesis market. One of the key reasons behind the growth of the regional segments is the fast development of the ...

The spines in Group I demonstrated higher rates of radiographically evident fusion at eight weeks than did the spines in Group III or Group IV (p , 0.05). Manual testing of the spines at four weeks revealed variable fusion rates (five of six in Group I, two of six in Group II, and none of six in Group Ill). At eight weeks, all six spines in Group I, three of the six in Group II, and no spine in Group III or IV had fused. Histologic analysis of the spines in Groups I, II, and III demonstrated varying amounts of residual demineralized bone matrix and new bone formation. Group-1 spines demonstrated the most new bone formation. ...

The radioactively labelled constituents present in bone matrix were compared 12 days after injection of either [(14)C]glucosamine or plasma [(14)C]glycoprotein. Both precursors are utilized in the synthesis of organic matrix by bone tissue. Cortical bone from animals injected with [(14)C]glucosamine contains radioactivity derived from glucosamine and plasma glycoproteins and all glycoprotein fractions are labelled. Plasma [(14)C]glycoprotein labels the less acidic glycoproteins to a greater extent than the more acidic components. An antibody has been raised against the less-acidic-glycoprotein fraction of bone. The latter contains a glycoprotein of alpha-mobility that appears to be concentrated specifically in bone tissue and which is present also in plasma. This alpha-glycoprotein accounts for a large proportion of the components labelled and retained in bone matrix after [(14)C]glucosamine injection.

Of course, these proposals must be assessed in the light of the limitations of the models, which probably represent a simplification of the complex and different ways in which normal mammalian bone is formed at different sites. Nevertheless, it is likely that the same general types of control mechanisms are active in each of the ...

It is not possible to say if this is a direct effect of estrogens on bone or the result of secondary effects but it suggests that in transsexuals receiving high dose estrogen therapy there is a decrease in bone matrix formation.

A demineralized bone matrix is produced by a process in which a bone body is placed in a first processing solution comprising an acid to demineralize the bone body. The bone body is periodically removed from the first solution at specific time intervals to perform at least one test, such as a compression test, on a mechanical property of the bone body. When the test yields a desired result, the bone body is exposed to a second processing solution that is less acidic than the first, thus minimizing the exposure of the bone body to the harsh acidic conditions of the demineralization phase of the process.

Osteoblasts are responsible for deposition of the mineralized bone matrix. Osteoblasts attach to the surface of the bone matrix, proliferate, and secrete type I collagen and bone-specific non-collagenous proteins such as osteocalcin. These proteins are crucial for mineralization of the bone matrix ...

Results: At the time of sacrifice, statistically significant differences between the four types of defects in the total area of bone regeneration, percentage of neoformed bone matrix, medullary space, or contact between particulate biomaterial and neoformed bone matrix were not found. All defects showed a significant increase in neoformed bone matrix as sacrifice was delayed, but a uniform pattern was not followed. Only defects treated with ß-TCP-Fn-ADSCs showed a significant increase in the bone regeneration area when animals sacrificed at 3 months were compared to those sacrificed at 1 month (P = .006 ...

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecules storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters. ...

TY - JOUR. T1 - The role of a composite, demineralized bone matrix and bone marrow in the treatment of osseous defects. AU - Tiedeman, J. J.. AU - Garvin, K. L.. AU - Kile, T. A.. AU - Connolly, J. F.. PY - 1995/1/1. Y1 - 1995/1/1. N2 - The efficacy of demineralized bone matrix (DBM) used alone and with bone marrow as a graft material in the treatment of osseous defects was evaluated in 48 patients. Of these 48 patients, 39 were available to follow up and review. Follow up averaged 19 months for all patients. In the entire series, 30 of 39 patients demonstrated osseous union for a 77% success rate. Patients with fracture nonunion represented the most recalcitrant group clinically, with union achieved in only 61% of these cases. Overall, the 39 patients grafted with DBM demonstrated healing that was comparable to results achieved with standard lilac crest bone graft. The results indicate the DBM and marrow composite grafting is a suitable alternative to autologous iliac crest bone graft for use ...

DOI: 10.11607/prd.00.0510 The effect of the pure-phase beta-tricalcium phosphate (beta-TCP) Cerasorb on bone regeneration was evaluated in hollow titanium cylinders implanted in the posterior jaws of five volunteers. Beta-TCP particles were inserted inside the cylinders and harvested 6 months after placement. The density of the newly formed bone inside the bone-growing chambers measured 27.84% 24.67% in test and 17.90% 4.28% in control subjects, without a statistically significant difference. Analysis of the histologic specimens revealed that the density of the regenerated bone was related to the density of the surrounding bone. The present study demonstrates the spontaneous healing of infrabony artificial defects, 2.5 mm diameter, in the jaw. The pure beta-TCP was resorbed simultaneously with new bone formation, without interference with the bone matrix formation. (Int J Periodontics Restorative Dent 2003;23:69 77 ...

The aim here was to explore a new graft material that excludes the need to harvest autogenous bone from patients. Forty-two critical-size (10 x 15 mm) defects were created in rabbit mandibles bilaterally. Five groups of six defects each were grafted with autogenous endochondral (EC) bone, autogenous intramembranous (IM) bone, fresh-frozen allogeneic IM bone only, fresh-frozen allogeneic IM bone and demineralized bone matrix powder prepared from intramembranous bone (DBM IM) only, and fresh-frozen allogeneic IM bone and basic fibroblast growth factor (bFGF) mixed with DBM IM powder. The remaining defects were used as controls. Three weeks after surgery, the defects were retrieved for histological analysis. The amount of new bone formation was quantified by image analysis. No bone formed across the defect in the controls; 224% more new bone formed in defects grafted with composite allogeneic IM bone/DBM IM than in those grafted with allogeneic IM bone alone (p < 0.001); 550% more new bone was ...

The highly intertwined, cross-linked structure of collagen makes it reasonable that fragments of this molecule could survive for 68 million years. Even if the individual protein strands break down, the fiber would still remain largely intact because of all the association points. Once the protein strand breaks, the fragments are held in close proximity by the contact points. This forced closeness allows for broken strands to occasionally rejoin and reform the original protein. If the broken strands were not held juxtaposed to each other, the fragments would diffuse away from each other, thus, preventing the reversal of the degradation process.. Finally, collagens association with the bone matrix provides added stability to the collagen proteins. Within the bone matrix, collagen fibers adsorb to the mineral component of bone. The contact with the surface protects the protein and keeps the pieces of collagen juxtaposed whenever the protein strands break.. Collagens abundance further explains its ...

You must limit the use of your damaged limb. Relax and accept that you cannot do the things you used to normally do. If you do, try to do things too soon, you will possibly lengthen the time it takes to get back to normal. But, right now, lets talk about how you might help to speed your recovery time. Because bone is about 70% mineral content, it is high in phosphorus, magnesium, silicon, zinc, and of course, calcium, along with some other minerals. Bone is also very high in protein content. A high-protein diet will provide some of the building blocks needed to synthesize a new bone matrix.. Plant-based proteins are recommended, such as nuts, oats, and quinoa, instead of animal and dairy proteins which contain more fat. Amino acids found in protein, such as lysine, arginine, glycine, cysteine and glutamine are responsible for the absorption of calcium and the regeneration of bone tissue. Anti-oxidants, like vitamins E, C and K, may aid in fracture healing by suppressing inflammation. By adding ...
