Boraldi F, Burns JS, Bartolomeo A, Dominici M, Quaglino D. Mineralization by mesenchymal stromal cells is variously modulated depending on commercial platelet lysate preparations. Cytotherapy 2017; 20:335-342. [PMID: 29289444 DOI: 10.1016/j.jcyt.2017.11.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2017] [Revised: 10/13/2017] [Accepted: 11/22/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND AIMS Numerous cellular models have been developed to investigate calcification for regenerative medicine applications and for the identification of therapeutic targets in various complications associated with age-related diseases. However, results have often been contradictory due to specific culture conditions, cell type ontogeny and aging status. Human platelet lysate (hPL) has been recently investigated as valuable alternative to fetal bovine serum (FBS) in cell culture and bone regeneration. A parallel comparison of how all these multiple factors may converge to influence mineralization has yet to be reported. METHODS To compare mineralization of human mesenchymal cell types known to differ in extracellular matrix calcification potency, bone marrow-derived mesenchymal stromal cells and dermal fibroblasts from neonatal and adult donors, at both low and high passages, were investigated in an ex vivo experimental model by supplementing the osteogenic induction medium with FBS or with hPL. Four commercial hPL preparations were profiled by liquid chromatography/electrospray ionization quadrupole time-of-flight spectrometry, and mineralization was visualized by von Kossa staining and quantified by morphometric evaluations after 9, 14 and 21 days of culture. RESULTS Data demonstrate that (i) commercial hPL preparations differ according to mass spectra profiles, (ii) hPL variously influences mineral deposition depending on cell line and possibly on platelet product preparation methods, (iii) donor age modifies mineral deposition in the presence of the same hPL and (iv) reduced in vitro proliferative capacity affects osteogenic induction and response to hPL. CONCLUSION Despite the standardized procedures applied to obtain commercial hPL, this study highlights the divergent effects of different preparations and emphasizes the importance of cellular ontology, donor age and cell proliferative capacity to optimize the osteogenic induction capabilities of mesenchymal stromal cells and design more effective cell-based therapeutic protocols.

Abstract
Objectives The
purpose of the present study was to evaluate the efficacy of adding
platelet-rich plasma (PRP) to a new highly purified bovine allograft
(Laddec®) in the bone regeneration of cystic bony defects
augmented following cystectomy. Material and Methods Study
sample included 20 patients undergoing cystectomy in which the bone
defect was filled with PRP and Laddec®. All patients were
examined with periapical radiographs before operation and at follow-up.
After 3 months, at re-entry surgery for implant placement, bone core was
taken for histological and histomorphometric analysis. Results The
postoperative successive radiographs showed a good regeneration of bone
in the height of bony defects with application of PRP to bone graft. By
the first postoperative month, about 48% of the defect was filled, which
gradually increased in each month and showed about 90% of defect-fill by
6 months. Histological and histomorphometric analysis, showed a
significant presence of bone tissue and vessels, with newly formed bone
in contact with anorganic bone particles. The mean volume of vital bone
was 68 ± 1.6% and the mean percentage of vital bone was 48 ± 2.4%. The
mean percentage of inorganic particles in tissues was 20 ± 1.2% of the
total volume. All the samples analyzed did not evidence the presence of
inflammatory cells. Conclusions The
results of this study showed how the use of Laddec® in
association with platelet-rich plasma allows bone regeneration and has a
potential for routine clinical use for regeneration of cystic bony
defects.

Abstract
Serum of animal origin and in particular fetal bovine serum is the most commonly utilized cell culture medium additive for in vitro cell growth and differentiation. However, several major concerns have been raised by the scientific community regarding the use of animal sera for human cell-based culture applications. Among the possible alternatives to the animal serum, platelet-derived compounds have been proposed since more than 10 years. Nevertheless, the high degree of variability between the different platelet preparations, and the lack of standardized manufacturing and quality control procedures, made difficult to reach a consensus on the applicability of this novel cell culture medium supplement. In this study, we describe the preparation of a standardized platelet-rich plasma (PRP) derivative obtained starting from human-certified buffy coat samples with a defined platelet concentration and following protocols including also freeze-drying, gamma irradiation and biological activity testing prior the product release as cell culture medium additive. Biological activity testing of the different preparations was done by determining the capability of the different PRP preparations to sustain human bone marrow mesenchymal stem cell (MSC) clone formation and proliferation. Taking advantage of a developed MSC in vitro clonogenicity test, we also determined biological activity and stability of the freeze-dried gamma-sterilized PRP preparations after their storage for different times and at different temperatures. The PRP effects on cell proliferation were determined both on primary cell cultures established from different tissues and on a cell line. Results were compared with those obtained in "traditional" parallel control cultures performed in the presence of bovine serum [10% fetal calf serum (FCS)]. Compared to FCS, the PRP addition to the culture medium increased the MSC colony number and average size. In primary cell cultures and in cell line cultures, the PRP promoted cell proliferation also in conditions where the FCS had not a proliferation stimulating effect due to either the nature of the cells and the tissue of origin (such as human articular chondrocytes from elderly patients) or to the critical low density cell seeding (such as for HeLa cells). In summary, the standardized PRP formulation would provide an "off-the-shelf" product to be used for the selection and expansion of several cell types also in critical cell culture conditions.

Abstract
The development of controlled release systems for the regeneration of bone, cartilage, and osteochondral interface is one of the hot topics in the field of tissue engineering and regenerative medicine. However, the majority of the developed systems consider only the release of a single growth factor, which is a limiting step for the success of the therapy. More recent studies have been focused on the design and tailoring of appropriate combinations of bioactive factors to match the desired goals regarding tissue regeneration. In fact, considering the complexity of extracellular matrix and the diversity of growth factors and cytokines involved in each biological response, it is expected that an appropriate combination of bioactive factors could lead to more successful outcomes in tissue regeneration. In this review, the evolution on the development of dual and multiple bioactive factor release systems for bone, cartilage, and osteochondral interface is overviewed, specifically the relevance of parameters such as dosage and spatiotemporal distribution of bioactive factors. A comprehensive collection of studies focused on the delivery of bioactive factors is also presented while highlighting the increasing impact of platelet-rich plasma as an autologous source of multiple growth factors.

Abstract
A new generation of scaffolds capable of acting not only as support for cells but also as a source of biological cues to promote tissue regeneration is currently a hot topic of in bone Tissue Engineering (TE) research. The inclusion of growth factor (GF) controlled release functionalities in the scaffolds is a possible strategy to achieve such goal. Platelet Lysate (PL) is an autologous source of GFs, providing several bioactive agents known to act on bone regeneration. In this study, chitosan-chondroitin sulfate nanoparticles loaded with PL were included in a poly(D,L-lactic acid) foam produced by supercritical fluid foaming. The tridimensional (3D) structures were then seeded with human adipose-derived stem cells (hASCs) and cultured in vitro under osteogenic stimulus. The osteogenic differentiation of the seeded hASCs was observed earlier for the PL-loaded constructs, as shown by the earlier alkaline phosphatase peak and calcium detection and stronger Runx2 expression at day 7 of culture, in comparison with the control scaffolds. Osteocalcin gene expression was upregulated in presence of PL during all culture period, which indicates an enhanced osteogenic induction. These results suggest the synergistic effect of PL and hASCs in combinatory TE strategies and support the potential of PL to increase the multifunctionality of the 3D hybrid construct for bone TE applications.

Abstract
This article describes the development of a new surgical approach to periodontal treatment. Twenty patients who suffered from bone defects without existing bony walls due to adult periodontitis were treated in three different groups using methods of bone tissue engineering. At that time no surgical technique existed that could be applied to those patients to generate new bone. The periodontal surgeries were performed between 2004 and 2008. All patients received follow-up examinations at 6, 12, and 24 months after surgical procedure. Measured parameters were compared to baseline. The surgical approach and the augmentation material have been improved based on the results of the previous group. This strategy was applied because of the ethical fact that a medical treatment of patients has to be carried out with the knowledge and experience of previous settings. All groups received recombinant human bone morphogenetic protein 2 and platelet-rich plasma. The above-mentioned procedure had been approved in other indications in the field of oral and maxillofacial surgery. The first group underwent conventional muco-periosteal flap technique and obtained an augmentation with absorbable collagen sponge (ACS). The second and third groups were treated using endoscopically assisted microsurgery due to wound healing disturbances that appeared in the first group. The augmentation was carried out with demineralized bone matrix (DBM) instead of ACS (group 2) or tricalciumphosphate as a further development instead of DBM (group 3). The radiological control 12 months (group 1), 18 months (group 2), and 2 years (group 3) after surgery proved the following results-first group: 1.7 mm (average) vertical bone development (VBD); second group: 2.5 mm (average) VBD; third group: 3.2 mm (average) VBD. These results of single patient treatment open new ways into periodontal surgery. They have to be confirmed by prospective case series and multicenter studies.

Abstract
Objectives The purpose of this article was to review and critically assess the use of
platelet rich plasma, recombinant human bone morphogenetic protein-2 and
different scaffolds (i.e. tricalciumphosphate, polycaprolactone,
demineralized bone matrix and anorganic bovine bone mineral) in oral and
maxillofacial surgery comparing the relevant literature and own clinical
experience. Material and Methods A literature review was conducted using MEDLINE, MEDPILOT and COCHRANE
DATABASE OF SYSTEMATIC REVIEWS. It concentrated on manuscripts and overviews
published in the last five years (2006-2010). The key terms employed were
platelet rich plasma, bone morphogenetic proteins and their combinations
with the above mentioned scaffolds. The results of clinical studies and
animal trials were especially emphasized. The statements from the literature
were compared with authors’ own clinical data. Results New publications and overviews demonstrate the advantages of platelet rich
plasma in bone regeneration. The results from the literature review were
discussed and compared with the publications detailing authors' own
experiences. Conclusions A favourable outcome concerning newly grown bone was achieved combining
platelet rich plasma in addition to optimal matrices with or without
recombinant human bone morphogenetic protein-2, depending on the clinical
case. As a consequence, the paradigm shift from transplantation of
autogenous bone to bone tissue engineering appears promising.

Abstract
Injectable scaffolds held great promise for the reconstruction of bone defects. We prepared an injectable composite named PTC by combining TCP/chitosan (TC) with platelet-rich plasma (PRP). The objective of this study was to investigate the composite's mechanical and biological properties. First, we found that the introduction of PRP in TC showed no adverse effect on mechanical strength and that there were no significant differences in compressive strength between PTC and TC (P>0.05). In cell culture experiments, both cell count and alkaline phosphatase (ALP) activity measurements of PTC were higher than those of TC. The high levels of Cbfa1 and TGF-beta were detected early in PTC-induced MSCs by reverse transcriptase polymerase chain reaction. Bone formation following expression of collagen type I, osteocalcin, osteonectin and calcium nodules was also observed in PRP-induced MSCs. Finally, this composite was injected into the tibial bone defect in a goat model, and its ability to induce bone regeneration was observed. Sixteen weeks after the implantation of this composite, the tibial defects had completely recuperated, with significantly better formation of mature bone and less residual material than in the control. These results demonstrate that our composite, with its concomitant mechanical strength, biocompatibility, and osteoinductive properties, has significant potential as an injectable material for the treatment of bone defects.
