Abstract

BackgroundThe global landscape of induced pluripotent stem cell (iPSC) resources remains heavily skewed toward European, North American, and East Asian populations, leaving the Middle East and North Africa (MENA) region critically underrepresented. This disparity hinders the application of precision medicine in populations with unique genetic backgrounds, particularly those with high rates of consanguinity and distinctive rare disease profiles. To address this gap, we established the Saudi Bank of Induced Pluripotent Stem Cells (SBiPSCs), at King Abdullah International Medical Research Centre (KAIMRC). The bank comprises two major complementary arms: one dedicated to the derivation and biobanking of iPSCs from individuals with rare and common genetic disorders, and a second focused on Human Leukocyte Antigen (HLA)-based iPSC banking to support the development of immunocompatible cell therapies. MethodsSBiPSCs operates within King Abdulaziz Medical City in Jeddah under the Ministry of National Guard for Health Affairs (MNGHA)s ethical and clinical framework. To establish the repository, we implemented a clinic-guided enrolment strategy in which treating physicians, briefed on the banks objectives, recruited patients with confirmed genetic diagnoses. Peripheral blood samples were collected, processed, and cells were reprogrammed using non-integrating episomal plasmids. All derived lines underwent rigorous quality control in accordance with International Society for Stem Cell Research (ISSCR) standards, including assessment of pluripotency markers, genomic integrity, and trilineage differentiation potential. To demonstrate our iPS characterization workflow and translational utility, iPSCs from a Saudi patient with familial Long QT Syndrome (LQTS) and a healthy sibling were differentiated into functional cardiac organoids. Simultaneously, for the HLA-based banking arm, the Saudi Stem Cell Donor Registry (SSCDR) database was leveraged to identify donors predicted to provide maximal coverage for the Saudi population. ResultsTo date, SBiPSCs has successfully generated 37 iPSC lines derived from 19 Saudi patients and healthy donors. All lines exhibit robust expression of pluripotency markers, maintain normal karyotypes, and demonstrate differentiation capacity. To demonstrate our characterization pipeline and translational utility, iPSCs from an LQTS patient and a healthy sibling were generated, validated, and differentiated into beating cardiac organoids that recapitulated the disease phenotype, with microelectrode array analysis confirming prolonged field potential durations mirroring the clinical QT prolongation. Furthermore, the HLA-based banking arm has expanded to include two homozygous iPSC lines, which together provide immunological compatibility for approximately 9% of the Saudi population. ConclusionsSBiPSCs represents the first centralized iPSC repository in the MENA region. The SBiPSCs is well-positioned to accelerate the translation of stem cell research into scalable, immunocompatible cell therapies and precision medicine applications aligned with national and regional healthcare priorities.

Generation of a transgenic cephalopod

Coleoid cephalopods (cuttlefish, octopus, and squid) are marine mollusks with elaborate nervous systems that support a diverse repertoire of complex behaviors. These include the neural control of the color, pattern, and texture of the skin, facilitating both adaptive camouflage and innate patterning that may reflect internal state. The development of transgenic cephalopods expressing fluorescent proteins, optogenetic actuators, and reporters of neural activity would contribute a new and important technology to cephalopod biology. The generation of transgenic cephalopods, however, has remained a major challenge. Here, we report the development of stable transgenic dwarf cuttlefish (Ascarosepion bandense) expressing ubiquitous nuclear-localized mScarlet, a red fluorescent protein. We evaluated multiple strategies for transgenesis, and established cuttlefish lines using both CRISPR and the transposons Sleeping Beauty and Minos. The stable expression of transgenes enabled live imaging of cell dynamics during embryonic development. The Minos transposon emerged as the most efficient transgenesis strategy and is adaptable to promoters and transgenes of choice. These strategies now enable the generation of diverse genetic tools for mechanistic studies of cephalopod biology.

Large language model-based bibliometric evaluation of population descriptors in human genetics

As the use of population descriptors such as race, ethnicity, and ancestry have become increasingly common in modern genetics research, there have been growing calls to critically examine their use. Most notably, in 2023, the National Academies of Science, Engineering, and Medicine (NASEM) published a report titled Using Population Descriptors in Genetics and Genomics Research: A New Framework for an Evolving Field, which included eight specific and actionable recommendations for researchers to implement the ethical and accurate use of population descriptors in genetic research. Here, we use the 2023 NASEM report as a benchmark to analyze the use of population descriptors in genome-wide association studies (GWAS). We develop a general toolkit for large language model-based bibliometrics, operationalize the report's recommendations into an evaluation framework, and apply this framework to evaluate all 4,007 papers from the GWAS Catalog published between 2007 and 2025 with full text available on PubMedCentral. We find significant improvements in adherence to NASEM report recommendations over time. However, most improvements predate the publication of the NASEM report itself, suggesting the report functioned primarily as a synthesis of existing best practices rather than a catalyst for change. We conclude by highlighting opportunities for growth in the field of human genetics.

Mitigating biases of rescaling in forward-in-time population genetic simulations

Forward-in-time population genetic simulations are widely used in evolutionary analyses, but simulating large populations and long genomic regions remains computationally demanding. To reduce this cost, parameter rescaling is widely employed, in which the original evolutionary process is approximated by one with a smaller population size and fewer generations. Recently, several studies using the SLiM simulator have raised concerns about the accuracy of this rescaling approach. In this study, we show that many of the biases reported in these studies can be mitigated by using a different simulation algorithm. These results reveal that the accuracy of parameter rescaling depends on how well the simulation algorithm preserves diffusion-limit properties under rescaling.
