Patients, whether in research or care settings, must be offered accurate information about risks and the current state of evidence for novel stem cell-based interventions. Publication of data without paywalls is encouraged. Recommendation 3.4.4.2: In general, initial tests of a novel strategy should be tested under lower-risk conditions before escalating to higher risk study conditions even if they are more likely to confer therapeutic benefit. from the inner cell mass of blastocyst stage human embryos, are capable of dividing without The term "tissue culture" was coined by American pathologist Montrose Thomas Burrows. The review process for the procurement of human cells and tissues should be predicated on the source of the material and its intended use as described in the three tiers below. For experiments in embryonic stem cell derivation, somatic cell nuclear transfer, somatic cell reprogramming, parthenogenesis, or androgenesis, that the resulting cells or stem cell lines derived would carry some or all of the DNA of the donor and therefore be partially or completely genetically matched to the donor. Standards help enable such collaborations and support efficient clinical translation in many ways. Physicians and payers need to be confident that the evidence they use to make important healthcare decisions is rigorous and unbiased. In Stem Cell Information [World Wide Web site]. Recommendation 2.5.1: These guidelines should be upheld and enforced through standards of academic, professional, and institutional self-regulation. Pre-existing immunity to viruses used to make gene transfer vectors may limit their application in vivo. reproductive treatment would comply with the Guidelines, so long as specific consent for the donation is that the donor(s) would not receive financial or any other benefits from any such 2010. Gynecol. Because of this variability, investigators and veterinarian staff must be aware of normal behaviors of individual NHPs and must know how to identify potential signs of stress and distress. The Research aimed at generating human totipotent cells that have the potential to sustain embryonic development in vitro. Factors that are common to many stem cell products include the cells proliferation and differentiation potentials, source (autologous, allogeneic), type of genetic manipulation, if any, homologous versus non-homologous or ectopic use, their persistence in the recipient, and the anticipated integration of cells into tissues or organs (versus, for example, encapsulation). These guidelines are based on the following principles: As directed by Executive Order 13505, the NIH shall review and update these Guidelines periodically, Recommendation 3.4.2.3: Stem cell-based interventions must be aimed toward being clinically competitive with existing therapies or meeting a unique therapeutic demand. In all such cases, the choice of a control arm should be explicitly justified. Repositories are encouraged to distribute them internationally to enable their dissemination. Of crucial importance is that these groups collectively have the scientific, medical, and ethical expertise to conduct necessary review and oversight. Likewise, stem cell lines procured from vendors are permissible for stem cell research, provided the vendor generated and distributed the stem cell lines in a manner consistent with the original donor consent and contemporaneous ethical and regulatory standards. Scientific rationale and merit of the proposal: Research involving human embryonic cells or human embryos and gametes requires that scientific goals and methods be scrutinized to ensure scientific rigor. Investigators should develop and adopt measures to maintain contact with research subjects. Visit The Archives for the previous versions of the ISSCR Guidelines for Stem Cell Research and Clinical Translation, as well as their translations. Substantially Manipulated Stem Cells, Cells, and Tissues. (2006). those eligible under prior Presidential policy, i.e., "grandfathered." Autologous transplantation: Refers to the transplantation to an animal or human patient of his/her own cells. 2.3.2 Informed Consent for the Donation of Human Cells and Tissues. Ensuring that research is performed according to scrupulous ethical standards is a legitimate concern for the peer review and editorial process of scientific publication. Lau, D., Ogbogu, U., Taylor, B., Stafinski, T., Menon, D., and Caulfield, T. (2008). Researchers are encouraged to make the materials readily accessible to the biomedical research community for non-commercial research. Repositories must receive and preserve the material transfer agreements for any material deposit and ensure its full execution prior to the transfer of materials to the requesting investigators. Others noted that because the stem cells eligible for use in research using NIH funding under Private firms seeking to develop and market stem cell-based interventions should work with public and philanthropic organizations to make safe and effective products available on an affordable basis to disadvantaged patient populations. Teratoma: A benign, encapsulated mass of complex differentiated tissues comprising elements of all three embryonic germ layers: ectoderm, endoderm, and mesoderm. Further reading. Provided appropriate expertise is available to ensure that the scientific, ethical, and legal aspects of the research can be rigorously evaluated, the specialized oversight can occur through preexisting institutional review processes that assess the participation of human subjects in research, the procurement of human tissues in and for research, or biosafety and ethical issues associated with research. [43] Examples of progenitor cells are vascular stem cells that have the capacity to become both endothelial or smooth muscle cells. Clinicians obtaining informed consent and clinics at which informed consent is sought may not profit from the procurement of fetal tissues for research. The NIH will undertake all enforcement actions in accordance with applicable statutes, All studies involving the use of non-human primates must be conducted under the close supervision of qualified veterinary personnel with expertise in their care and their unique environmental needs. However, registries should not be substituted for well-regulated randomized controlled clinical trials designed to evaluate the safety and efficacy of complex products like stem cell and gene-based interventions. Such procedures should not exceed a minor increase over the minimal risk when trial populations lack capacity to provide valid informed consent. However, given that many cellular products developed in the future will represent entirely novel entities with difficult-to-predict behaviors, scientists must work with regulators to ensure that the latest information is available to inform the regulatory process. Preclinical experiments confront many sources of bias and confounding factors, including selection bias. Further, the fairness of access should be consistent with local legal requirements and standards and the standards of ethical, evidence-based medicine. pluripotent stem cells. Stem cell-based clinical trials may involve populations, such as children or persons with advanced neurological disorders, who may lack knowledge, comprehension and decision-making capacity required to provide informed consent. These processes can include isolation and purification processes, tissue culture and expansion of the cells, genetic manipulation, or other steps. They also may be essential to evaluate issues of manufacturing scale up, or anatomical factors that are likely to mediate a therapeutic effect (for example, bone, cartilage, or tendon in a load-bearing model). Download the ISSCR SAMPLE FORM Microsoft Word document: Uniform Human Embryonic Stem Cell-related Materials Transfer Agreement, Assessing tumorigenicity of genome-modified cell interventions. Stem cell and embryo research show great promise for advancing our understanding of human development and disease, including research to address issues pertinent to the earliest stages of human development, such as: the causes of miscarriage; epigenetic, genetic and chromosomal disorders; and human reproduction. Culture-acquired genetic abnormalities may be a significant risk and should be part of in process and/or final product testing for stem cell products that have undergone extensive expansion in vitro. [22] MSCs produce many immunomodulatory molecules including prostaglandin E2 (PGE2),[23] nitric oxide,[24] indoleamine 2,3-dioxygenase (IDO), interleukin 6 (IL-6), and other surface markers such as FasL,[25] PD-L1 and PD-L2. will be centralized at the NIH as follows: The materials submitted must demonstrate that the hESCs were derived from human embryos: Hyun, I. Cell potency is a cell's ability to differentiate into other cell types. not limited to withholding funds pending correction of the problem, disallowing all or part of the costs of Being studied under an Investigational New Drug Application (IND), which is a clinical investigation plan submitted and allowed to proceed by the FDA. important to recognize that the principles of ethical research, e.g., voluntary informed consent to should be specified in the material transfer agreement. Posting a clear and fair cost schedule for distribution of materials. The cells, which are long and thin, are widely dispersed and the adjacent extracellular matrix is populated by a few reticular fibrils but is devoid of the other types of collagen fibrils. and scientific issues on which a similar consensus has not emerged. Addressing misconceptions and misestimations that derive from public representations of the field. The first and best developed approach to genome editing exploits engineered endonucleases to deliver a DNA double-stranded break (DSB) to the intended target sequence. Although the cells may come from Furthermore, patient registries are useful tools for monitoring adverse events after regulators have approved a product for routine clinical use. Third, researchers should publish trials, methods, and sub-analyses in full. Housing NHPs in social groups best replicates the social interactions they experience in the wild and thereby promotes species-typical behaviors and psychological well-being. Code of Practice, 9th Edition. Nature 574, E8E11 (2019). Advantaged populations should make efforts to share any benefits of research with disadvantaged populations. 2018;24(11):16961700.
