A randomized, controlled clinical trial of autologous stromal vascular fraction cells transplantation to promote mechanical stretch-induced skin regeneration. Stem Cell Res Ther 2021; 12:243. [PMID: 33858504 PMCID: PMC8048343 DOI: 10.1186/s13287-021-02318-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Accepted: 03/30/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The regeneration response of the skin to mechanical stretching in vivo has been explored in reconstructive surgery to repair large-scale deformities. The ability of the skin to regenerate limits the reconstructive outcome. Here, we propose an approach in which autologous stromal vascular fraction (SVF) cells and mechanical stretching are combined to overcome this limitation and promote skin regeneration. METHODS This randomized, blinded, placebo-controlled clinical trial screened 22 participants undergoing tissue expansion with exhausted regeneration. Twenty eligible participants received intradermal injections of the SVF or placebo treatments. Follow-ups were conducted at 4, 8, and 12 weeks to assess efficacy and at 2 years to assess safety. The primary endpoint was the expanded skin thickness at 12 weeks. The secondary endpoints included skin thickness at 4 and 8 weeks, the expansion index (EI), and the skin texture score at 12 weeks. RESULTS The skin thickness of the SVF group was significantly higher than that of the control group at both 8 weeks (mean difference 0.78 [95% CI - 1.43 to - 0.11]; p = 0.018) and 12 weeks (0.65 [95% CI - 1.30 to - 0.01]; p = 0.046). In the SVF group, the increase in skin thickness was significant at 4 weeks (0.49 [95% CI - 0.80 to - 0.06]; p = 0.010) to 8 weeks (0.45 [95% CI - 0.92 to 0.02]; p = 0.026) and maintained after 12 weeks, whereas that in the control group was reduced after 8 weeks (0.42 [95% CI - 0.07 to 0.91]; p = 0.037). The SVF group showed greater EI increases than the control group (0.50 [95% CI - 0.00 to 0.99]; p = 0.047). The skin texture scores in the SVF group were greater than those in the control group at 12 weeks. Histologically, SVF-treated expanded skin showed more proliferating cells and blood vessels, and the extracellular matrix volume increased. No severe adverse events occurred. CONCLUSIONS Transplantation of SVF cells can expedite the potency of mechanical stretch-induced skin regeneration and provide clinical reconstruction with plentiful tissue. TRIAL REGISTRATION This trial was registered with the Chinese Clinical Trial Registry, ChiCTR2000039317 (registered 23 October 2020-retrospectively registered).

Abstract
The large economic burden on the global health care systems is due to the increasing number of symptomatic osteoarthritis (OA) knee patients whereby accounting for greater morbidity and impaired functional quality of life. The recent developments and impulses in molecular and regenerative medicine have paved the way for inducing the biological active cells such as stem cells, bioactive materials, and growth factors towards the healing and tissue regenerative process. Mesenchymal stem cells (MSCs) act as a minimally invasive procedure that bridges the gap between pharmacological treatment and surgical treatment for OA. MSCs are the ideal cell-based therapy for treating disorders under a minimally invasive environment in conjunction with cartilage regeneration. Due to the worldwide recognized animal model for such cell-based therapies, global researchers have started using the various sources of MSCs towards cartilage regeneration. However, there is a lacuna in literature on the comparative efficacy and safety of various sources of MSCs in OA of the knee. Hence, the identification of a potential source for therapeutic use in this clinical scenario remains unclear. In this article, we compared the therapeutic effects of various sources of MSCs in terms of efficacy, safety, differentiation potential, durability, accessibility, allogenic preparation and culture expandability to decide the optimal source of MSCs for OA knee.

Abstract
BACKGROUND Stem cells are undifferentiated cells with multilineage differentiation potential. They can be collected from bone marrow, fat, amniotic fluid, and teeth. Stem cell-based therapies have been widely used to treat multiple diseases, such as cardiac disease, and hematological disorders. The cells may also be beneficial for controlling the disease course and promoting tissue regeneration in oral and maxillofacial diseases. Oral-derived gingival mesenchymal stem cells are easy to access and the donor sites heal rapidly without a scar. Such characteristics demonstrate the beneficial role of GMSCs in oral and maxillofacial diseases. OBJECTIVE We summarize the features of GMSCs, including their self-renewal, multipotent differentiation, immunomodulation, and anti-inflammation properties. We also discuss their applications in oral and maxillofacial disease treatment and tissue regeneration. CONCLUSION GMSCs are easily harvestable adult stem cells with outstanding proliferation, differentiation, and immunomodulation characteristics. A growing body of evidence indicates that GMSCs have strong potential use in accelerating wound healing and promoting the regeneration of bone defects, periodontium, oral neoplasms, salivary glands, peri-implantitis, and nerves. Moreover, alginate, polylactic acid and polycaprolactone can be used as biodegradable scaffolds for GMSC encapsulation. Various growth factors can be applied to the corresponding scaffolds to obtain the desired GMSC differentiation and phenotypes. Three-dimensional spheroid culture systems could optimize GMSC properties and improve the performance of the cells in tissue engineering. The immunomodulatory property of GMSCs in controlling oral and maxillofacial inflammation needs further research.

Abstract
AIM The present study was conducted with an aim to assess the awareness about existence of dental stem cells among dental professionals. MATERIALS AND METHODS A total sample size of 100 dental professionals in the age group of 22-32 years, comprising of 28 interns, 46 postgraduate students, and 26 senior residents from various specialties was selected. A self-administered, hand-delivered, 10-point questionnaire was used to assess the awareness, knowledge, and attitude of dental professionals towards dental stem cells. Results were documented and statistically analyzed using chi-square test. RESULTS A total of 72% dental professionals were aware about dental stem cells with dental curriculum books being the main source of information. Note that 81% of positive respondents were aware about the different types and a total of 28% were aware about the procedure to procure dental stem cells. Only 33.3% of positive respondents were aware about existence of dental stem cell banks in India. CONCLUSION A high level of awareness about dental stem cells and its applications was noted during the course of this study. A significant association of age and type of practice with awareness of dental stem cells and knowledge regarding their use in developing nondental tissues was observed. A positive attitude towards recommending dental stem cell banking was seen.

Abstract
The field of regenerative medicine is looking for a pluripotent/multipotent stem cell able to differentiate across germ layers and be safely employed in therapy. Unfortunately, with the exception of hematopoietic stem/progenitor cells (HSPCs) for hematological applications, the current clinical results with stem cells are somewhat disappointing. The potential clinical applications of the more primitive embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) have so far been discouraging, as both have exhibited several problems, including genomic instability, a risk of teratoma formation, and the possibility of rejection. Therefore, the only safe stem cells that have so far been employed in regenerative medicine are monopotent stem cells, such as the abovementioned HSPCs or mesenchymal stem cells (MSCs) isolated from postnatal tissues. However, their monopotency, and therefore limited differentiation potential, is a barrier to their broader application in the clinic. Interestingly, results have accumulated indicating that adult tissues contain rare, early-development stem cells known as very small embryonic-like stem cells (VSELs), which can differentiate into cells from more than one germ layer. This chapter addresses different sources of stem cells for potential clinical application and their advantages and problems to be solved.

Abstract
BACKGROUND This study aimed to evaluate the characteristics of faculty and research activities of basic stem cell research groups in China. METHODS A questionnaire was administered to persons who knew the information among 46 basic stem cell research groups in China. Multiple linear regression models and repeated-measures analyses of variance were used. Repeated-measures analyses of variance were used. RESULTS Of the 46 groups, 39.1% did not have any faculty recruited from abroad from 2009 to 2013, 37.0% did not have any faculty with junior-level title, 34.8% had ≤25.0% faculty with either M.D. or Ph.D. degree. Papers published in SCI journals per faculty and having faculty recruited from abroad were positively associated with research funding per faculty. The groups with faculty recruited from abroad had significantly higher research funding per faculty over time compared with the group without faculty recruited from abroad. Repeated-measures analyses of variance showed the group with faculty recruited from abroad had significantly higher research funding per faculty over time compared with the group without faculty recruited from abroad. CONCLUSION To increase the development of basic stem cell research, some characteristics of human resources should be improved, and the groups should recruit more faculty with overseas experience.

Abstract
Objective Stem cells that have unlimited proliferation potential as well as differentiation potency are considered to be a
promising future treatment method for incurable diseases. The aim of the present study is to evaluate the future trend of stem
cell researches from researchers’ viewpoints.
Materials and Methods This was a cross-sectional descriptive study on researchers involved in stem cell research at
Royan Institute. We designed a questionnaire using a qualitative study based on expert opinion and a literature review.
Content validity was performed using three rounds of the Delphi method with experts. Face validity was undertaken by
a Persian literature expert and a graphics designer. The questionnaire was distributed among 150 researchers involved
in stem cell studies in Royan Institute biology laboratories.
Results We collected 138 completed questionnaires. The mean age of participants was 31.13 ± 5.8 years; most
(60.9%) were females. Participants (76.1%) considered the budget to be the most important issue in stem cell research,
79.7% needed financial support from the government, and 77.5% felt that charities could contribute substantially to
stem cell research. A total of 90.6% of participants stated that stem cells should lead to commercial usage which
could support future researches (86.2%). The aim of stem cell research was stipulated as increasing health status
of the society according to 92.8% of the participants. At present, among cell types, importance was attached to cord
blood and adult stem cells. Researchers emphasized the importance of mesenchymal stem cells (MSCs) rather than
hematopoietic stem cells (HSCs, 57.73%). The prime priorities were given to cancer so that stem cell research could
be directed to sphere stem cell research whereas the least preference was given to skin research.
Conclusion Regenerative medicine is considered the future of stem cell research with emphasis on application of
these cells, especially in cancer treatment.

Abstract
OBJECTIVE After the introduction of assisted reproductive techniques, human embryos were officially introduced into laboratories and now thousands of them are cryopreserved in such settings. Embryonic stem cells and the future application of such cells in the treatment of disease opened the door to further research on human embryos. These developments raise many ethical issues, some of which have religious aspects. The main question is: what is the embryo? Should we consider it a human being? Thus, the purpose of this study was to investigate attitudes towards the personhood of the embryo. MATERIALS AND METHODS In this cross sectional study, 203 infertile patients (n=406), 54 clinic staff and 49 embryo researchers, selected using convenience sampling at the Royan Institute, completed a questionnaire on personhood of human embryo. The questionnaire had been developed following qualitative research and had satisfied face and content validity tests. RESULTS At the pre-implantation stage the majority of participants in all three groups considered the human embryo as "not a human being". Also, at the post-implantation stage of development, the majority of infertile couples and clinic staff considered the embryo as "not a human being" but, half the researchers (51%) considered the embryo in this stage as a "potential human". Half of the infertile couples considered the human fetus before ensoulment time (19th week of pregnancy according to the Shiite Islamic scholars) as "not-human being", while more than half of researchers (55.1%) considered it as a "potential human". CONCLUSION Ensoulment time is a major and important border for personhood. Most infertile couples and clinic staff consider the human embryo as "not a human being" but majority of all study participants considered the human fetus to be a complete human after ensoulment time.

Abstract
I could tell many war stories about my experience serving on the President's Council on Bioethics-one of the most controversial national bioethics commissions so far-but I want to focus instead on how the experience influenced my views on bioethics, politics, and the potential contributions of national commissions. The executive order that established the Council directed it to consider policy questions, but it spoke primarily of providing a forum for national discussion, inquiry, and education. In this sense, the Council's mission departed from that of other national bioethics commissions, which have had more direct policy functions. Most bioethics commissions consider a range of ethical positions in their reports, but their primary objective has been to develop consensus recommendations on whatever topic they are addressing. The Council's executive order moved away from the consensus-based policy model and called for deep attention to contested ideas. Although the search for consensus may be the most suitable approach for policy activities, it can lead to a bland and anemic version of bioethics. The Council sought to contribute thick bioethical analysis.

Abstract
BACKGROUND Stem cell research has been extensively explored worldwide to enhance human health in medical setting. Nevertheless, there is currently no full understanding of the stem cell knowledge and attitude levels among student nurses in Malaysia. This study aimed to assess the level of stem cell knowledge, attitude toward stem cell application in medicine, and its association with years of education, among Universiti Sains Malaysia (USM) undergraduate nursing students. METHODS A cross-sectional study (n = 88) was conducted using self-administered questionnaire consisted of demographic information, stem cells knowledge and attitude statements. Data was analysed using Statistical Package Social Software 20.0. RESULTS The majority of participants (92%) had moderate knowledge score about stem cells. Many students (33%) worried that stem cell application might cause a harm to humanity yet had a positive (76.1%) attitude towards its therapeutic potential (45.5%). Poor correlation between knowledge and attitude (r = 0.08) indicated that acceptance towards stem cell is not solely based on the knowledge level but also on other factors including religion and culture. CONCLUSION Therefore, this study suggests that various educational programs on stem cell should be implemented considering the religion, cultural, social, and behavioural determinants in the population to improve stem cell knowledge and encourage a more positive attitude towards stem cells in medicine among these nursing students.

Abstract
Rapid progress in biotechnology has introduced a host of pressing ethical and policy issues pertaining to stem cell research. In this review, we provide an overview of the most significant issues with which the stem cell research community should be familiar. We draw on a sample of the bioethics and scientific literatures to address issues that are specific to stem cell research and therapy, as well as issues that are important for stem cell research and therapy but also for translational research in related fields, and issues that apply to all clinical research and therapy. Although debate about the moral status of the embryo in human embryonic stem cell research continues to have relevance, the discovery of other highly multipotent stem cell types and alternative methods of isolating and creating highly multipotent stem cells has raised new questions and concerns. Induced pluripotent stem cells hold great promise, but care is needed to ensure their safety in translational clinical trials, despite the temptation to move quickly from bench to bedside. A variety of highly multipotent stem cells - such as mesenchymal stem/stromal cells and stem cells derived from amniotic fluid, umbilical cord blood, adipose tissue, or urine - present the opportunity for widespread biobanking and increased access. With these increased opportunities, however, come pressing policy issues of consent, control, and justice. The imperatives to minimize risks of harm, obtain informed consent, reduce the likelihood of the therapeutic misconception, and facilitate sound translation from bench to bedside are not unique to stem cell research; their application to stem cell research and therapy nonetheless merits particular attention. Because stem cell research is both scientifically promising and ethically challenging, both the application of existing ethical frameworks and careful consideration of new ethical implications are necessary as this broad and diverse field moves forward.

Abstract
Social scientists have begun elucidating the variables that influence public trust in science, yet little is known about hype in biotechnology and its effects on public trust. Many scholars claim that hyping biotechnology results in a loss of public trust, and possibly public enthusiasm or support for science, because public expectations of the biotechnological promises will be unmet. We argue for the need for empirical research that examines the relationships between hype, public trust, and public enthusiasm/support. We discuss the complexities in designing empirical studies that provide evidence for a causal link between hype, public trust, and public enthusiasm/support, but also illustrate how this may be remedied. Further empirical research on hype and public trust is needed in order to improve public communication of science and to design evidence-based education on the responsible conduct of research for scientists. We conclude that conceptual arguments made on hype and public trust must be nuanced to reflect our current understanding of this relationship.

Abstract
Social scientists have begun elucidating the variables that influence public trust in science, yet little is known about hype in biotechnology and its effects on public trust. Many scholars claim that hyping biotechnology results in a loss of public trust, and possibly public enthusiasm or support for science, because public expectations of the biotechnological promises will be unmet. We argue for the need for empirical research that examines the relationships between hype, public trust, and public enthusiasm/support. We discuss the complexities in designing empirical studies that provide evidence for a causal link between hype, public trust, and public enthusiasm/support, but also illustrate how this may be remedied. Further empirical research on hype and public trust is needed in order to improve public communication of science and to design evidence-based education on the responsible conduct of research for scientists. We conclude that conceptual arguments made on hype and public trust must be nuanced to reflect our current understanding of this relationship.

Abstract
Genetic engineering has emerged as a powerful mechanism for understanding biological systems and a potential approach for redressing congenital disease. Alongside, the emergence of these technologies in recent decades has risen the complementary analysis of the ethical implications of genetic engineering techniques and applications. Although viral-mediated approaches have dominated initial efforts in gene transfer (GT) methods, an emerging technology involving engineered restriction enzymes known as zinc finger nucleases (ZFNs) has become a powerful new methodology for gene editing. Given the advantages provided by ZFNs for more specific and diverse approaches in gene editing for basic science and clinical applications, we discuss how ZFN research can address some of the ethical and scientific questions that have been posed for other GT techniques. This is of particular importance, given the momentum currently behind ZFNs in moving into phase I clinical trials. This study provides a historical account of the origins of ZFN technology, an analysis of current techniques and applications, and an examination of the ethical issues applicable to translational ZFN genetic engineering in early phase clinical trials.

Abstract
Many features of the existing biomedical research enterprise rest on questionable judgments about the value of research. Policymakers and research ethicists make assumptions about research value that aren't necessarily warranted. A more balanced view of research value could contribute to more defensible decisions about research policy and practice.

Abstract
During the last 50-60 years, due to development of medical care and hygienically safe living conditions, the average life span of European citizens has substantially increased, with a rapid growth of the population older than 65 years. This trend places ever-growing medical and economical burden on society, as many of the older subjects suffer from age-related diseases and frailty. Coping with these problems requires not only appropriate medical treatment and social support but also extensive research in many fields of aging-from biology to sociology, with involvement of older people as the research subjects. This work anticipates development and application of ethical standards suited to dynamic advances in aging research. The aim of this review is to update the knowledge in ethical requirements toward recruitment of older research subjects, obtaining of informed consent, collection of biological samples, and use of stem cells in preclinical and clinical settings. It is concluded that application of adequate ethical platform markedly facilitates recruitment of older persons for participation in research. Currently, the basic ethical concepts are subjected to extensive discussion, with participation of all interested parties, in order to guarantee successful research on problems of human aging, protect older people from undesired interference, and afford their benefits through supporting innovations in research, therapy, and care.

Abstract
Embryonic stem cells are actively debated in political and public policy arenas. However, the connections between stem cell innovation and overall health care policy are seldom elucidated. As with many controversial aspects of medical care, the stem cell debate bridges to a variety of social conversations beyond abortion. Some issues, such as translational medicine, commercialization, patient and public safety, health care spending, physician practice, and access to insurance and health care services, are core health policy concerns. Other issues, such as economic development, technologic progress, fiscal politics, and tort reform, are only indirectly related to the health care system but are frequently seen through a health care lens. These connections will help determine whether the stem cell debate reaches a resolution, and what that resolution might be.
