Opinion: Toward inclusive global governance of human genome editing

Linking research of biomedical datasets

Biomedical data preprocessing and efficient computing can be as important as the statistical methods used to fit the data; data processing needs to consider application scenarios, data acquisition and individual rights and interests. We review common principles, knowledge and methods of integrated research according to the whole-pipeline processing mechanism diverse, coherent, sharing, auditable and ecological. First, neuromorphic and native algorithms integrate diverse datasets, providing linear scalability and high visualization. Second, the choice mechanism of different preprocessing, analysis and transaction methods from raw to neuromorphic was summarized on the node and coordinator platforms. Third, combination of node, network, cloud, edge, swarm and graph builds an ecosystem of cohort integrated research and clinical diagnosis and treatment. Looking forward, it is vital to simultaneously combine deep computing, mass data storage and massively parallel communication.

Scientists' Views on Scientific Self-Governance for Human Genome Editing Research

As research on human gene editing has grown, a variety of prominent international organizations are considering how best to govern such research. But what role do scientists engaged in genome editing think they should have in developing research governance? In this study, we present results from a survey of 212 U.S.-based scientists regarding views on human genome editing governance. Most did not believe that scientists should be allowed to self-govern human genome editing research. Open-ended responses revealed four main reasons: conflicts of interest, the inevitability of rare "bad apples," historical evidence to the contrary, and the limitations of scientific expertise. Analyses of open-ended responses also revealed scientists' views on how human gene editing research should be governed. These views emphasize interdisciplinary professional and public input. The study results illustrate a noteworthy shift in the scientific community's traditional vision of professional autonomy and can inform ongoing efforts to develop research governance approaches.

Responsible governance of human germline genome editing in China

Considerable improvements have been made to gene editing technology, which has been increasingly applied to research involving humans. Nevertheless, human heritable germline genome editing is associated with a series of potential ethical, legal, and social risks, which have generated major controversies and discussions worldwide, especially after the “gene-edited babies” incident. Influenced by this incident, China has realized the importance of ethical governance in the field of life science and technology, has accelerated legislative and policy efforts in this field, and has gradually moved toward the direction of “precautionary” ethical governance. Black letter analysis, big data public opinion analysis, and other research methods are used in this paper. This paper explores the scientific background, ethical debates, and latest developments regarding China’s regulatory framework for human germline gene editing after the “gene-edited babies” controversy and provides several recommendations on the future governance system of human germline gene editing in China. This paper argues that in recent years, the ethics governance of germline genome editing in China has been accelerated and great changes have been made. However, the regulatory system for germline genome editing requires further improvement in three aspects: coordination of legislation and agencies, establishment of an ethics review system at high levels, and public participation and education.

Alginate-Based Hydrogels and Tubes, as Biological Macromolecule-Based Platforms for Peripheral Nerve Tissue Engineering: A Review

Unlike the central nervous system, the peripheral nervous system (PNS) has an inherent capacity to regenerate following injury. However, in the case of large nerve defects where end-to-end cooptation of two nerve stumps is not tension-free, autologous nerve grafting is often utilized to bridge the nerve gaps. To address the challenges associated with autologous nerve grafting, neural guidance channels (NGCs) have been successfully translated into clinic. Furthermore, hydrogel-based drug delivery systems have been extensively studied for the repair of PNS injuries. There are numerous biomaterial options for the production of NGCs and hydrogels. Among different candidates, alginate has shown promising results in PNS tissue engineering. Alginate is a naturally occurring polysaccharide which is biocompatible, non-toxic, non-immunogenic, and possesses modifiable properties. In the current review, applications, challenges, and future perspectives of alginate-based NGCs and hydrogels in the repair of PNS injuries will be discussed.
