Generation of human induced pluripotent stem cell lines from patients with FGFR2 -linked syndromic craniosynostosis
Disease Models & Mechanisms 2025 Sep
Abstract
Craniosynostosis is a multigenic congenital condition in which one or more calvarial sutures have prematurely fused during the development of the fetus. Pathogenic variants in FGFR2 are associated with the development of syndromic craniosynostosis, such as Crouzon, Apert and Pfeifer syndromes. Investigation of FGFR2 -linked craniosynostosis is hindered by the lack of appropriate in vitro models. Patient-derived human induced pluripotent stem cell (hiPSC) in vitro disease models provide the opportunity to investigate the disease, identify molecular targets for pharmaceutical treatments, and enable the generation of autologous pluripotent stem cell catalogues. Here, we report three patient-derived hiPSC lines carrying the C342Y, S252W or E565G FGFR2 pathogenic variant. The patient hiPSC lines express characteristic pluripotency markers and display distinct phosphorylation profiles under unstimulated conditions. FGFR2 C342Y showed autophosphorylation in the absence of bFGF ligand, although downstream docking proteins PLCγ and FRS2α were not phosphorylated. FGFR2 S252W and FGFR2 E565G hiPSCs showed increased phosphorylation of docking proteins PLCγ and FRS2α, whereas FGFR2 was not phosphorylated. These patient hiPSC lines provide molecular and cellular options to investigate FGFR2 -linked craniosynostosis in the patient-specific genomic context and develop therapeutic modalities.
Implementing a trilineage differentiation in the ReproTracker assay for improved teratogenicity assessment
Frontiers in Toxicology 2025 Sep
Abstract
IntroductionExposure to teratogenic compounds during pregnancy can lead to significant birth defects. Given the considerable variation in drug responses across species, along with the financial and ethical challenges associated with animal testing, the development of advanced human-based in vitro assays is imperative for effectively identifying potential human teratogens. Previously, we developed a human induced pluripotent stem cells (hiPSCs)-based biomarker assay, ReproTracker, that follows the differentiation of hiPSCs into hepatocytes and cardiomyocytes. The assay combines morphological profiling with the assessment of time-dependent expression patterns of cell-specific biomarkers to detect developmental toxicity responses.MethodsTo further increase the predictability of the assay in identifying potential teratogens, we added differentiation of hiPSCs towards neural rosette-like cells. We evaluated the performance of the extended assay with a set of 51 well-known in vivo teratogens and non-teratogens, including the compounds listed in the ICH S5 reference list.ResultsThe optimized assay correctly identified (neuro)developmental toxicants that were not detected in the hepatocyte and cardiomyocyte differentiation assays. These compounds selectively downregulated gene and protein expression of the neuroectodermal marker PAX6 and/or neural rosette marker NESTIN in a concentration-dependent manner and disrupted the differentiation of hiPSCs towards neural rosette-like cells. Overall, based on the current dataset, the addition of neural commitment improved the assay accuracy (from 72.55% to 86.27%) and sensitivity (from 67.50% to 87.50%), when compared to the previously described assay.DiscussionIn summary, trilineage differentiation expanded the spectrum of teratogenic agents detectable by ReproTracker, making the assay an invaluable tool for early in vitro teratogenicity screening.
CLDN10-driven lineage decision in an amnion and primordial germ cell progenitor at the amnion-epiblast boundary in primates
Genome Biology 2025 Sep
Abstract
BackgroundA growing body of evidence from primate embryos as well as in vitro systems supports the notion that amnion and primordial germ cell (PGC) lineage progressing cells share a common precursor.ResultsTo gain comprehensive transcriptomic insights into this critical but poorly understood precursor and its progeny, we examine the evolving transcriptome of a developing human pluripotent stem cell-derived model of amnion and PGC formation at the single cell level. This analysis reveals several continuous amniotic fate progressing states with state-specific markers. Additionally, a progenitor-like cell, that displays bi-potential characteristics for amnion and PGC-like cell lineages and is marked by CLDN10, is identified. Strikingly, we find that expression of CLDN10 is restricted to the amnion-epiblast boundary region in our human post-implantation amniotic sac model as well as in peri-gastrula cynomolgus macaque embryos; moreover, this boundary region presents amnion and PGC progenitor-like transcriptional characteristics. Furthermore, our loss of function analysis shows that CLDN10 promotes amniotic but suppresses PGC-like fate.ConclusionsOverall, based on the single cell transcriptomic resource in this study, we identify a CLDN10+ amnion and PGC progenitor-like population at the amnion-epiblast boundary of the primate peri-gastrula, and present additional molecular clues as to how amnion and PGC may be formed at the amnion-epiblast boundary in human peri-gastrula. Supplementary InformationThe online version contains supplementary material available at 10.1186/s13059-025-03751-y.
