Molecular profiling of single cells has advanced our knowledge of the molecular basis of development. However, current approaches mostly rely on dissociating cells from tissues, thereby losing the crucial spatial context of regulatory processes. Here, we apply an image-based single-cell transcriptomics method, sequential fluorescence in situ hybridization (seqFISH), to detect mRNAs for 387 target genes in tissue sections of mouse embryos at the 8–12 somite stage. By integrating spatial context and multiplexed transcriptional measurements with two single-cell transcriptome atlases, we characterize cell types across the embryo and demonstrate that spatially resolved expression of genes not profiled by seqFISH can be imputed. We use this high-resolution spatial map to characterize fundamental steps in the patterning of the midbrain–hindbrain boundary (MHB) and the developing gut tube. We uncover axes of cell differentiation that are not apparent from single-cell RNA-sequencing (scRNA-seq) data, such as early dorsal–ventral separation of esophageal and tracheal progenitor populations in the gut tube. Our method provides an approach for studying cell fate decisions in complex tissues and development. Improved integration of spatial and single-cell transcriptomic data provides insights into mouse development.

SummaryChina has been criticized for the long drug delay for a long time. There was little understanding of Chinese drug lag formation from the investigational new drug (IND) submission to the new drug application (NDA) approval. Therefore, we analyzed the problem of drug lag in China cumulating from the clinical trial starting lag to the lags formed during the regulatory process and discerned the key underlying factors. After investigating the availability in China of new molecular entities (NMEs) approved by the Food and Drug Administration (FDA) between 1999 and 2019, we find that even though cutting regulatory process could reduce the approval lag, the clinical trial starting time in China is more important in drug lag reduction than shortening development time and review time. The reduction of the regulatory process also needs continuous efforts by defining the clinical value based on the medical needs, regulatory procedure harmonization, and intensive discussions between applicants and regulators during the drug development process. Meanwhile, proactive approaches should be taken to encourage developing the first generics in China. More importantly, enhancing domestic research and development capabilities is still the key to cutting the drug lag. Moreover, the China National Medical Product Administration (NMPA) should attach importance to the accumulation of regulation experience on innovative drugs and transform the style of regulating generics to new drugs.

Background : Section 114 of the 1997 US FDA Modernization Act (FDAMA) is an important vehicle for pharmaceutical companies to promote the economic value of their drugs to formulary decision makers, but little is known about how the Section has been interpreted and used. Methods : We conducted a web-based survey of a convenience sample of 35 outcomes directors of major pharmaceutical and biotechnology companies. We asked them about their interpretation of, and experiences with, Section 114, as well as their views regarding the FDA’s role in the matter, and whether the advent of comparative effectiveness research (CER) will affect the use of Section 114 promotions. Results : Of the 35 experts, 16 (46%) completed the survey. 81% stated they always or frequently consider using Section 114 when making promotional claims for drugs. 75% stated that the FDA should issue guidance on how to make such promotions to payers, especially what qualifies as healthcare economic information and competent and reliable scientific evidence. Most expected to use Section 114 to a greater extent in the future, and agreed that the increased focus on CER would increase Section 114 use. Conclusions : The survey suggests strong awareness about Section 114 among the outcomes directors and some use of the Section for promotional purposes. It also reflects a belief that CER will increase use of Section 114 promotions, and that guidance from the FDA is needed. More clarity and, ideally, flexible interpretation from the FDA is warranted, especially given the rise of CER.

MicroRNAs (miRNAs) maintain cellular homeostasis by blocking mRNAs by binding with them to fine-tune the expression of genes across numerous biological pathways. The 2024 Nobel Prize in Medicine and Physiology for discovering miRNAs was long overdue. We anticipate a deluge of research work involving miRNAs to repeat the history of prizes awarded for research on other RNAs. Although miRNA therapies are included for several complex diseases, the realization that miRNAs regulate genes and their roles in addressing therapies for hundreds of diseases are expected; but with advancement in drug discovery tools, we anticipate even faster entry of new drugs. To promote this, we provide details of the current science, logic, intellectual property, formulations, and regulatory process with anticipation that many more researchers will introduce novel therapies based on the discussion and advice provided in this paper.

There is increasing emphasis on patient-centred research to support the development, approval and reimbursement of health interventions that best meet patients’ needs. However, there is currently little guidance on how meaningful patient engagement may be achieved. An expert working group, representing a wide range of stakeholders and disciplines, was convened by the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) and the World Health Organization (WHO). Through a structured, collaborative process the group generated practical guidance to facilitate optimal patient engagement in clinical development and regulatory decisions. Patient engagement is a relational process. The principles outlined in this report were based on lessons learned through applied experience and on an extensive dialogue among the expert participants. This practice guidance forms a starting point from which tailoring of the approach to suit different chronic diseases may be undertaken.

The field of transplantation has witnessed the emergence of Advanced Therapy Medicinal Products (ATMPs) as highly promising solutions to address the challenges associated with organ and tissue transplantation. ATMPs encompass gene therapy, cell therapy, and tissue-engineered products, hold immense potential for breakthroughs in overcoming the obstacles of rejection and the limited availability of donor organs. However, the development and academic research access to ATMPs face significant bottlenecks that hinder progress. This opinion paper emphasizes the importance of addressing bottlenecks in the development and academic research access to ATMPs by implementing several key strategies. These include the establishment of streamlined regulatory processes, securing increased funding for ATMP research, fostering collaborations and partnerships, setting up centralized ATMP facilities, and actively engaging with patient groups. Advocacy at the policy level is essential to provide support for the development and accessibility of ATMPs, thereby driving advancements in transplantation and enhancing patient outcomes. By adopting these strategies, the field of transplantation can pave the way for the introduction of innovative and efficacious ATMP therapies, while simultaneously fostering a nurturing environment for academic research.

While the private sector is leading the way in digital transformation, the public sector is perceived as missing the opportunity. The way forward in this transformation is pointed out as adopting data-driven technologies as drivers of public policies. This will undoubtedly transform the regulatory process. To better understand how these technologies would intervene in the policy cycle and the effect of this transformation on regulation, this paper studies the work of the Organisation for Economic Co-operation and Development on the matter. Adopting the public policy cycle as an analytical lens and illuminated by the insights of Critical Data Studies, this paper deepens the understanding of how these technologies could change the policy cycle and bring together steps previously conceived as subsequential stages. This transformation can trigger a real disruption of the regulatory process as we currently know it.

By definition, regulatory rules (in legal context called norms ) intend to achieve specific behaviour from business processes, and might be relevant to the whole or part of a business process. They can impose conditions on different aspects of process models, e.g., control-flow, data and resources etc. Based on the rules sets, norms can be classified into various classes and sub-classes according to their effects. This paper presents an abstract framework consisting of a list of norms and a generic compliance checking approach on the idea of (possible) execution of processes. The proposed framework is independent of any existing formalism, and provides a conceptually rich and exhaustive ontology and semantics of norms needed for business process compliance checking. Apart from the other uses, the proposed framework can be used to compare different compliance management frameworks (CMFs).
