Platelet-concentrated and platelet poor-plasma promote different pattern on immunohistochemical expression of TGF-β1, however they impairs the osteoneogensis in calvarial defects treated with autograft due suppression of osteocalcin. Acta Cir Bras 2021; 36:e360604. [PMID: 34287607 PMCID: PMC8291903 DOI: 10.1590/acb360604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 05/21/2021] [Indexed: 11/22/2022] Open
Abstract
Purpose Herein we evaluated the effects of platelet concentrate (PC) and
platelet-poor plasma (PPP) on bone repair using noncritical defects in the
calvaria of rabbits and compared them to the presence of TGF-β1 and
osteocalcin on reparative sites. Methods Five noncritical defects of 8.7 mm in diameter were created on the calvaria
of 15 animals. Each defect was treated differently, using autograft (ABG),
ABG associated with PC (ABG + PC), ABG with PPP (ABG + PPP), isolated PPP,
and blood clot (control). The animals were submitted to euthanasia on the
second, fourth and sixth week post-surgery. Results The defects that received ABG+PC or PPP demonstrated lower bone formation
when compared to specimens that received ABG in the same period. These
results coincided to significant higher immunopositivity for TGF-β1 for
specimens that received PC, and lower presence of cytokine in the group PPP.
However, either higher or lower presence of TGF-β1 were also correlated to
lower presence of osteocalcin. Likewise, these results were similar to
findings in specimens treated only with PPP when compared to control. Conclusions PC and PPP were not effective when applied in association with ABG.
Similarly, isolated use of PPP was not beneficial in optimizing the bone
repair.

The efficacy and safety of platelet-rich fibrin for rotator cuff tears: a meta-analysis. J Orthop Surg Res 2018; 13:202. [PMID: 30103777 PMCID: PMC6090707 DOI: 10.1186/s13018-018-0881-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2018] [Accepted: 07/03/2018] [Indexed: 12/11/2022] Open
Abstract
Background The aim of this meta-analysis was to evaluate the efficacy and safety of platelet-rich fibrin (PRF) in improving clinical outcomes in rotator cuff tears. Methods We searched the following databases: Pubmed, Embase, and Cochrane library databases from inception to April 2018. Studies that compared platelet-rich fibrin versus placebo for rotator cuff tears were included in this meta-analysis. Risk ratio (RR) with 95% confidence interval (CI) was pooled for discontinuous outcome, and weighted mean difference (WMD) with 95% CI was pooled for continuous outcome. Stata 12.0 was used for meta-analysis. Results A total of eight studies with 219 patients were finally included in this meta-analysis. Compared with the control group, PRF has a negative role in reducing the re-tear rate (RR = 1.30, 95% CI = 0.97 to 1.75; P = 0.082). Subgroup analysis of re-tear rate was consistent in all subgroup analyses (single row or double row, volume, and risk of bias). There was no significant difference between the American Shoulder and Elbow Surgeons scale, University of California at Los Angeles scale, Constant score, and side effect (P > 0.05). Conclusion In conclusion, our meta-analysis suggests that the PRF does not have better effect on improving the overall clinical outcomes and re-tear rate in the arthroscopic repair of rotator cuff tears.

Would Be Prophylactic Administrations of Low Concentration of Alendronate an Alternative for Improving the Craniofacial Bone Repair? A Preliminary Study Focused in the Period of Cellular Differentiation and Tissue Organization. J Craniofac Surg 2018; 28:1869-1873.

Abstract
BACKGROUND Alendronate (ALN) is a nitrogen-bisphosphonate that may induce an anabolic effect on craniofacial bone repair when administrated in low doses. Based on this premise, this study analyzed the influence of prophylactic low doses of ALN on bone healing in defects created in rabbit mandible. METHODS A 5 × 2-mm diameter deep defect was created in the calvaria of 28 rabbits. Fourteen of these rabbits received previously 50 μg/kg of 1% sodium ALN for 4 weeks, while the other rabbits received only 0.9% physiological saline solution (control). Animals were euthanized at 15 and 60 days postsurgery (n = 7), and the data were analyzed using histomorphometry and immunohistochemistry using the anti-CD34, bone morphogenetic protein -2 (BMP-2), and transforming growth factor (TGF)-β1 antibodies. RESULTS On the 15th day postsurgery, the specimens that received previous treatment with ALN demonstrated large vascular lumen and intense positivity to CD34 either concentrated in endothelium or cells spread among the reparative tissue. These results coincided with intense positivity for BMP-2+ cells and TGF-β1 that was concentrated in both cells and perivascular area. In contrast, the control group revealed scarce cells that exhibited CD34, BMP-2+, and the TGF-β1 was restricted for perivascular area on well-formed granulation tissue. These patterns of immunohistochemical result, especially found on the 15th day of analysis, seem to be responsible for the development of larger quantities of bone matrix in the specimens that receive ALN on the 60th day postsurgery. CONCLUSION These preliminary results showed that the prophylactic administration of low doses of ALN might be an alternative to craniofacial bone craniofacial bone repair because it increases the immunopositivity for TGF-β1 and consequently improves the CD34+ and BMP-2+ cells on reparative sites.

Abstract
Bone healing is a complex repair process that commences with the formation of a blood clot at the injured bone, termed hematoma. It has evidenced that a lack of a stable hematoma causes delayed bone healing or non-union. The hematoma at the injured bone constitutes the early healing microenvironment. It appears to dictate healing pathways that ends in a regenerative bone. However, the hematoma is often clinically removed from the damaged site. Conversely, blood-derived products have been used in bone tissue engineering for treating critical sized defects, including fibrin gels and platelet-rich plasma. A second generation of platelet concentrate that is based on leukocyte and fibrin content has also been developed and introduced in market. Conflicting effect of these products in bone repair are reported. We propose that the bone healing response becomes dysregulated if the blood response and subsequent formation and properties of a hematoma are altered. This review focuses on the central structural, cellular, and molecular components of a fracture hematoma, with a major emphasis on their roles in regulating bone healing mechanism, and their interactions with mesenchymal stem cells. New angles towards a better understanding of these factors and relevant mechanisms involved at the beginning of bone healing may help to clarify limited or adverse effects of blood-derived products on bone repair. We emphasize that the recreation of an early hematoma niche with critical compositions might emerge as a viable therapeutic strategy for enhanced skeletal tissue engineering.

Prolonged use of alendronate alters the biology of cranial repair in estrogen-deficient rats' associated simultaneous immunohistochemical expression of TGF-β1+, α-ER+, and BMPR1B. Clin Oral Investig 2017; 22:1959-1971. [PMID: 29197953 DOI: 10.1007/s00784-017-2292-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 11/21/2017] [Indexed: 01/06/2023]
Abstract
OBJECTIVES TGF-β1 is a cytokine that may induce both osteoneogenesis through Runx-2 or fibrosis via the transcription of α-smooth muscle actin (α-SMA). Because it has been previously known that alendronate increases the level of TGF-β1 and that under the usual condition of bone metabolism the estrogen may prevent the fibrotic effect of TGF-β1, the aim of this study was to evaluate if alendronate alters the cellular differentiation process post calvarial surgery in estrogen-deficient specimens. MATERIALS AND METHODS A transosseous defect that was 5 mm in diameter was created on the calvarium of each of 32 female rats with previous ovarian-salpingo-oophorectomy. All defects were treated with autografts, and 16 rats received the administration of 1 mg/kg of alendronate three times a week until euthanasia on the 15th and 60th day post surgery. Histomorphometric and immunohistochemical analyses of the expression of TGF-β1, estrogen receptor alpha nuclear (α-ER), α-SMA, BMPR1B, and Runx-2 were performed, and ELISA was used to measure the level of estrogen. RESULTS All animals demonstrated low levels of estrogen post ovarian-salpingo-oophorectomy. The histological results demonstrated larger bone matrix deposition in specimens treated with alendronate on the 15th day post surgery. The result was associated with a higher co-expression of TGF-β1, BMPR1B, and Runx-2 when compared with the control group. In addition, on the 60th day post surgery, the increase of bone matrix deposition from 15th to 60th day was discrete in specimens treated with alendronate compared with the control group. This result coincided with the intense simultaneous expression of TGF-β1, α-ER, and α-SMA, whereas the expression of BMPR1B and Runx-2 decreased. CONCLUSION The prolonged administration of alendronate altered the cranial repair in ovarian-salpingo-oophorectomized specimens due to the simultaneous occurrence of low estrogen and the presence of TGF-β1+/α-ER+ inducing the presence of α-SMA+, whereas BMPR1B and Runx-2 were suppressed. CLINICAL RELEVANCE The prolonged administration of alendronate alters osteoneogenesis and induces an unusual microenvironment in the bone that seems to imitate the physiological tissue damage that culminates in the loss of the functional layer of endometrium.

Abstract
In presence of large bone defects, delayed bone union, non-union, fractures, and implant surgery, bone reconstruction may be necessary. Different strategies have been employed to enhance bone healing among which the use of autologous platelet concentrates. Due to the high content of platelets and platelet-derived bioactive molecules (e.g., growth factors, antimicrobial peptides), they are promising candidates to increase bone healing. However, a high heterogeneity of both preclinical and clinical studies resulted in contrasting results. Aim of the present systematic review was to evaluate the efficacy of platelet concentrates in animal models of bone regeneration, considering the possible factors which might affect the outcome. An electronic search was performed on MEDLINE and SCOPUS databases. Animal studies with a minimum follow up of 2 weeks and a sample size of five subjects per group, using platelet concentrates for bone regeneration, were included. Articles underwent risk of bias assessment and further quality evaluation was done. Sixty studies performed on six animal species (rat, rabbit, dog, sheep, goat, and mini-pig) were included. The present part of the review considers only studies performed on rats and rabbits (35 articles). The majority of the studies were considered at medium risk of bias. Animal species, healthy models, platelet, growth factors and leukocytes concentration, and type of bone defect seemed to influence the efficacy of platelet concentrates in bone healing. However, final conclusions were not be drawn, since only few included studies evaluated leukocyte, growth factor content, or presence of other bioactive molecules in platelet concentrates. Further studies with a standardized protocol including characterization of the final products will provide useful information for clinical application of platelet concentrates in bone surgery.

Abstract
BACKGROUND Platelet-rich plasma (PRP) contains multiple growth factors and has been shown to enhance fat graft survival after lipotransfer. However, the molecular mechanisms mediating this effect remain unknown. Adipose-derived stem cells (ASCs) play an important role in fat graft survival and are a likely target for PRP-mediated effects. This study seeks to investigate the impact of PRP on ASC proliferation and adipogenic differentiation. METHODS Human ASCs were isolated using our laboratory protocol. The experiments were divided into four arms: (1) ASCs cultured in general culture medium alone; (2) ASCs in general culture medium + 5%, 10%, 15%, or 20% PRP; (3) ASCs cultured in adipogenic differentiation medium alone; (4) ASCs cultured in adipogenic medium + 5%, 10%, 15%, or 20% PRP. Cell proliferation was analyzed and comparative m-RNA expression of adipogenic genes was assessed by quantitative PCR. Protein expression was determined by western blot. RESULTS PRP significantly enhanced proliferation of ASCs, even in the presence of antiproliferative, proadipogenic media. In contrast, PRP inhibited adipogenic differentiation in adipogenic media, evidenced by decreased intracellular lipid accumulation and reduced adipogenic gene expression (PPAR-γ and FABP4). Inhibition appears to occur through downregulation of bone morphogenetic protein receptor IA (BMPRIA) and fibroblast growth factor receptor 1 (FGFR1). Interestingly, PRP elicited these effects across the entire range of doses studied. CONCLUSIONS PRP appears to modulate ASC function primarily by enhancing cell proliferation. The consequences of its impact on adipogenesis are less clear. Enhanced proliferation initially might set the stage for more robust regeneration and adipogenesis at later time points, providing an important target for ongoing research.

Abstract
BACKGROUND Infertility has become one of the major health problems worldwide, with its incidence having risen markedly in recent decades. There is an urgent need to investigate the pathological mechanisms behind infertility and to design effective treatments. However, this is made difficult by the fact that various biological factors have been identified to be related to infertility, including genetic factors. METHODS A network-based method was established to identify new genes potentially related to infertility. A network constructed using human protein-protein interactions based on previously validated infertility-related genes enabled the identification of some novel candidate genes. These genes were then filtered by a permutation test and their functional and structural associations with infertility-related genes. RESULTS Our method identified 23 novel genes, which have strong functional and structural associations with previously validated infertility-related genes. CONCLUSIONS Substantial evidence indicates that the identified genes are strongly related to dysfunction of the four main biological processes of fertility: reproductive development and physiology, gametogenesis, meiosis and recombination, and hormone regulation. GENERAL SIGNIFICANCE The newly discovered genes may provide new directions for investigating infertility. This article is part of a Special Issue entitled "System Genetics" Guest Editor: Dr. Yudong Cai and Dr. Tao Huang.

Abstract
In facial plastic surgery, the potential for direct delivery of growth factors from platelet preparations has been of particular interest for use in facial rejuvenation, recovery after facial surgery, and wound healing. A literature search was conducted through PubMed for the terms PRP, PRFM, platelet-rich plasma, platelet-rich fibrin matrix, platelet preparations, platelet therapy, growth factors, platelet facial, platelet facial rejuvenation, platelet wound healing, platelet plastic surgery. Articles pertaining to the use of platelet preparations in facial surgery and wound healing in plastic surgery after 2001 were included. Thirteen in vitro studies showed use of platelet-rich plasma (PRP) and platelet-rich fibrin matrix (PRFM) had a significant effect on cellular activity. Twenty-four out of 28 animal studies exhibited favorable results with use of a platelet preparation, including five of six studies that showed enhanced fat graft survival with addition of a platelet preparation. Twenty-three case series and clinical trials were identified, only two of which showed no differences. Twenty-one reported favorable results with use of various platelet preparations. A total of 47 studies used PRP, four studies evaluated Leukocyte-rich PRP, and fourteen studies used PRFM. The vast majority of studies examined show a significant and measurable effect on cellular changes, wound healing, and facial esthetic outcomes with use of platelet preparations, both topical and injectable. One must also consider possible publication bias against null results that may have had an influence on the data that were available for review. However, the preponderance of studies suggests that platelet preparations might represent an as-of-yet untapped adjunct in facial plastic surgery.
