RESUMEN

Premature ovarian failure (POF), a condition influenced by genetic and immune factors, remains incurable despite years of intensive research and significant efforts. This persisting challenge underscores the urgency to address this escalating health concern. Fortunately, stem cell regenerative medicine has emerged as a promising avenue for developing therapeutic strategies and innovative treatments for POF. Bibliometric analysis, renowned for its objectivity, systematic approach, and comprehensive coverage of a given field, has yet to be applied to the study of stem cell research in POF. This study used CiteSpace software to assess contributions and co-occurrence relationships among various countries/regions, institutes, journals, and authors. This approach also allowed us to identify research hotspots and promising future trends within this field. Additionally, we generated visualizing maps utilizing the Web of Science Core Collection (WOSCC) and PubMed publications. By providing valuable information and references, we aim to enhance the understanding of the challenges involved in translating stem cell regeneration into clinical therapeutic potential for POF. Furthermore, our analysis and findings guide researchers and clinicians, facilitating future collaborative research and clinical intervention efforts.

RESUMEN

Governance infrastructures streamline scientific and ethical provenance verification of human pluripotent stem cell (SC) lines. Yet, scientific developments (e.g., SC-derived embryo models, organoids) challenge research governance approaches to stored biospecimens, questioning the validity of informed consent (IC) models. Likewise, e-health platforms are driving major transformations in data processing, prompting a reappraisal of IC. Given these developments, participatory research platforms are identified as effective tools to promote longitudinal engagement, interactive decision-making, and dynamic governance. Learning from European initiatives piloting dynamic IC for biobanking and SC research, this Perspective explores the benefits and challenges of implementing dynamic IC and governance for SC.

RESUMEN

The recently issued ISSCR standards in stem cell research recommend registration of human pluripotent stem cell lines (hPSCs). Registration is critical to establishing stem cell provenance and connecting cell lines to data derived on those lines. In this study, we sought to understand common barriers to registration by conducting interviews with forty-eight Australian stem cell stakeholders, including researchers, clinicians, and industry professionals. Australian stem cell researchers do not routinely register their lines, and only a third of those Australian lines captured by an international registry have fully completed the registration process. Most registered Australian cell lines lack complete information about their ethical provenance or key pluripotency characteristics. Incomplete registration is poorly aligned with the goals of open science on which registries are founded. Users also expressed concerns about the quality of the incomplete information provided to the resource. Registration was considered negatively, for instance as a hurdle or barrier to publication, which impacted on user perceptions of usefulness of registration and lowered the likelihood that they would engage with registries to find resources. Broader adoption of registration by journals, and continued advocacy by stem cell societies, will be important levers for awareness and engagement with registration. Although the Australian community represents a small fraction of potential registry users, the results of this study suggest ways for journals, registries, funders, and the international stem cell community to improve registration compliance.

RESUMEN

Various groups including animal protection organizations, medical organizations, research centers, and even federal agencies such as the U.S. Food and Drug Administration, are working to minimize animal use in scientific experiments. This movement primarily stems from animal welfare and ethical concerns. However, recent advances in technology and new studies in medicine have contributed to an increase in animal experiments throughout the years. With the rapid increase in animal testing, concerns arise including ethical issues, high cost, complex procedures, and potential inaccuracies.Alternative solutions have recently been investigated to address the problems of animal testing. Some of these technologies are related to stem cell technologies, such as organ-on-a-chip, organoids, and induced pluripotent stem cell models. The aim of the review is to focus on stem cell related methodologies, such as organoids, that can serve as an alternative to animal testing and discuss its advantages and limitations, alongside regulatory considerations.Although stem cell related methodologies has shortcomings, it has potential to replace animal testing. Achieving this requires further research on stem cells, with potential societal and technological benefits.

RESUMEN

The translational stem cell research field has progressed immensely in the past decade. Development and refinement of differentiation protocols now allows the generation of a range of cell types, such as pancreatic ß-cells and dopaminergic neurons, from human pluripotent stem cells (hPSCs) in an efficient and good manufacturing practice-compliant fashion. This has led to the initiation of several clinical trials using hPSC-derived cells to replace lost or dysfunctional cells, demonstrating evidence of both safety and efficacy. Here, we highlight successes from some of the hPSC-based trials reporting early signs of efficacy and discuss common challenges in clinical translation of cell therapies.

RESUMEN

Introduction: Although stem cell research and therapeutic applications hold great promise for medical advancements, and have rapidly progressed globally, there remains a lack of genuine public awareness of the status of this subject in Saudi Arabia. Successful integration of stem cell therapy into healthcare relies on public awareness, understanding, and trust. Therefore, we aimed in this cross-sectional study to assess the public's knowledge, awareness, trust, support, participation, and confidence in stem cell treatments and centers involved in it. Materials and methods: A voluntary questionnaire of 20 questions was distributed randomly via social media outlets. Results: Three thousand five hundred eighty four individuals participated in the survey, with approximately half of them falling within the age range of 35-50 years (46.71%). Majority of the participants, 90.71%, would like to know more about stem cell therapy and more than half of the participants (56.94%) were unfamiliar with the idea, and a comparable proportion (50.41%) expressed concerns about the safety of stem cell therapy. A lower level of awareness, indicated by a score of 5, was evenly distributed across all age groups and genders. However, regardless of gender, older participants-especially those 50 years of age or older-tended to report higher levels of confidence, trust, and support than participants in other age groups. Moreover, trust, support, participation, and confidence score for those attained high school or less was statistically significantly lower than those attained master's or PhD degree. Of the participants, 33.57% had either received stem cell therapy themselves or known someone who had; about 24.07% of them reported that it was a cosmetic type of treatment. Conclusion: The study emphasizes the persistent need for awareness and educational initiatives to minimize the lack of public awareness and understanding of approved stem cell treatments in Saudi Arabia. It advocates for increased education, transparency, and communication to bridge knowledge gaps and enhance public trust to ensure the understanding of successful treatment.

RESUMEN

BACKGROUND: Exosomes and other secretory membrane vesicles are collectively referred to as extracellular vesicles (EVs). Relevant data indicate that stem cell-derived extracellular vesicles (SC-EVs) play a critical role in angiogenesis by transmitting crucial information such as proteins, second messengers, and genetic material between cells. Therefore, this study aimed to map current trends on SC-EVs for angiogenesis and provide directions for future research to advance this important field. METHODS: We conducted a thorough search for relevant studies on SC-EVs for angiogenesis from 2003 to 2023 using the Web of Science database. Subsequently, we used VOSviewer and CiteSpace to analyze the collected data. RESULTS: A total of 2359 relevant publications, which included original articles and reviews, related to the role of SC-EVs in angiogenesis were screened in this study based on the search strategy. China and the United States were leading in this field, with China having a higher output in terms of publications and citations (1172, 43681). Also, the top five universities were located in China, with Shanghai Jiao Tong University having the highest output. Stem Cell Research & Therapy and International Journal of Molecular Sciences, are prominent platforms for researchers in this field to share their findings and advancements, and they had most of published studies on SC-EVs for angiogenesis. The results derived from the cluster analysis suggested that future investigations should predominantly prioritize studying the involvement of SC-EVs in angiogenesis across various diseases, with a specific emphasis on skin wound healing. CONCLUSION: In this comprehensive review, global trends in SC-EVs for angiogenesis were analyzed. The analysis of journals, institutions, references, and keywords could assist researchers in deciding on the direction of research. The role of SC-EVs in promoting angiogenesis during wound healing and repair represents an emerging research focus.
