Abstract
Human induced Pluripotent Stem Cells (hiPSCs) represent an invaluable source of primary cells to investigate development, establish cell and disease models, provide material for regenerative medicine and allow more physiological high-content screenings. Here, we generated three healthy hiPSC control lines - IPi001-A/B/C - from primary amniotic fluid cells (AFCs), an infrequently used source of cells, which can be readily obtained from amniocentesis for the prenatal diagnosis of numerous genetic disorders. These AFCs were reprogrammed by non-integrative viral transduction. The resulting hiPSCs displayed normal karyotype and expressed classic pluripotency hallmarks.

Abstract
Recessive Dystrophic Epidermolysis Bullosa (RDEB) is a rare and severe genetic disease responsible for blistering of the skin and mucosa caused by a wide variety of mutations in COL7A1 encoding type VII collagen. We have generated Induced Pluripotent Stem Cells (iPSCs) from two RDEB patients' fibroblasts harboring homozygous recurrent mutations in COL7A1. Their pluripotent state was confirmed by gene and protein expression of stem cell markers OCT4, SOX2, TRA1/60 and SSEA4. Embryoid body formation followed by immunostaining and TaqMan scorecard analysis confirmed the capacity of RDEB iPSCs to differentiate into cell types from the three germ layers in vitro.

Abstract
Mutations in UNC45A, a co-chaperone for myosins, were recently found causative of a syndrome combining cholestasis, diarrhea, loss of hearing and bone fragility. We generated induced pluripotent stem cells (iPSCs) from a patient with a homozygous missense mutation in UNC45A. Cells from this patient, which were reprogrammed using integration-free Sendaï virus, have normal karyotype, express pluripotency markers and are able to differentiate into the three germ cell layers.

Abstract
Human pluripotent stem cells (hPSCs) have emerged as the most promising cellular source for cell therapies. To overcome the scale-up limitations of classical 2D culture systems, suspension cultures have been developed to meet the need for large-scale culture in regenerative medicine. Despite constant improvements, current protocols that use microcarriers or generate cell aggregates only achieve moderate amplification performance. Here, guided by reports showing that hPSCs can self-organize in vitro into cysts reminiscent of the epiblast stage in embryo development, we developed a physio-mimetic approach for hPSC culture. We engineered stem cell niche microenvironments inside microfluidics-assisted core-shell microcapsules. We demonstrate that lumenized three-dimensional colonies significantly improve viability and expansion rates while maintaining pluripotency compared to standard hPSC culture platforms such as 2D cultures, microcarriers, and aggregates. By further tuning capsule size and culture conditions, we scale up this method to industrial-scale stirred tank bioreactors and achieve an unprecedented hPSC amplification rate of 277-fold in 6.5 days. In brief, our findings indicate that our 3D culture system offers a suitable strategy both for basic stem cell biology experiments and for clinical applications.

Abstract
Variants in the UNC45A cochaperone have been recently associated with a syndrome combining diarrhea, cholestasis, deafness, and bone fragility. Yet the mechanism underlying intestinal failure in UNC45A deficiency remains unclear. Here, biallelic variants in UNC45A were identified by next-generation sequencing in 6 patients with congenital diarrhea. Corroborating in silico prediction, variants either abolished UNC45A expression or altered protein conformation. Myosin VB was identified by mass spectrometry as client of the UNC45A chaperone and was found misfolded in UNC45AKO Caco-2 cells. In keeping with impaired myosin VB function, UNC45AKO Caco-2 cells showed abnormal epithelial morphogenesis that was restored by full-length UNC45A, but not by mutant alleles. Patients and UNC45AKO 3D organoids displayed altered luminal development and microvillus inclusions, while 2D cultures revealed Rab11 and apical transporter mislocalization as well as sparse and disorganized microvilli. All those features resembled the subcellular abnormalities observed in duodenal biopsies from patients with microvillus inclusion disease. Finally, microvillus inclusions and shortened microvilli were evidenced in enterocytes from unc45a-deficient zebrafish. Taken together, our results provide evidence that UNC45A plays an essential role in epithelial morphogenesis through its cochaperone function of myosin VB and that UNC45A loss causes a variant of microvillus inclusion disease.

Human pluripotent stem cells are a powerful tool to study development, to model diseases or as cellular substrates for drug screening. We generated a human induced pluripotent stem cell (hiPSC) line from a healthy control donor. Peripheral blood mononuclear cells (PBMCs) from this donor were reprogrammed using integration-free Sendai virus. This cell line had normal karyotype, expressed pluripotency hallmarks and differentiated into the three primary germ layers.

Mutation in STING1gene, which encodes stimulator of type I IFN gene (STING) leads to its constitutive activation and thereby to a severe vasculopathy and sometimes a lupus-like disease. We generated induced pluripotent stem cells (iPSCs) from a patient carrying a rare heterozygous variant c.463G > A (resulting in a p.V155M substitution) in STING1. Cells from this patient, which were reprogrammed by non-integrative viral transduction, had normal karyotype, expressed pluripotency markers and were able to differentiate into the three germ cell layers.

Abstract
Inositol polyphosphates are vital metabolic and secondary messengers, involved in diverse cellular functions. Therefore, tight regulation of inositol polyphosphate metabolism is essential for proper cell physiology. Here, we describe an early-onset neurodegenerative syndrome caused by loss-of-function mutations in the multiple inositol-polyphosphate phosphatase 1 gene (MINPP1). Patients are found to have a distinct type of Pontocerebellar Hypoplasia with typical basal ganglia involvement on neuroimaging. We find that patient-derived and genome edited MINPP1−/− induced stem cells exhibit an inefficient neuronal differentiation combined with an increased cell death. MINPP1 deficiency results in an intracellular imbalance of the inositol polyphosphate metabolism. This metabolic defect is characterized by an accumulation of highly phosphorylated inositols, mostly inositol hexakisphosphate (IP6), detected in HEK293 cells, fibroblasts, iPSCs and differentiating neurons lacking MINPP1. In mutant cells, higher IP6 level is expected to be associated with an increased chelation of intracellular cations, such as iron or calcium, resulting in decreased levels of available ions. These data suggest the involvement of IP6-mediated chelation on Pontocerebellar Hypoplasia disease pathology and thereby highlight the critical role of MINPP1 in the regulation of human brain development and homeostasis. Tight regulation of inositol polyphosphate metabolism is essential for proper cell physiology. Here, the authors describe an early-onset neurodegenerative syndrome caused by loss-of-function mutations in the MINPP1 gene, characterised by intracellular imbalance of inositol polyphosphate metabolism.

Abstract
Human pluripotent stem cells offer a limitless source of cells for regenerative medicine. They are also highly valuable as tools to study development and pathologies or as cellular substrates to screen and test new drugs. We generated human induced pluripotent stem cell (hiPSC) lines from two unrelated healthy control donors. Peripheral blood mononuclear cells (PBMCs) from these donors were reprogrammed by non-integrative viral transduction, had normal karyotypes and expressed pluripotency hallmarks.

Abstract
Mutations of SOX10 result in a broad range of phenotypes including Waardenburg syndrome (WS types 2 and 4) that can be found in association with peripheral demyelinating neuropathy and/or central dysmyelinating leukodystrophy. Here, we generated induced pluripotent stem cells (iPSCs) from a patient carrying a de novo heterozygous missense mutation in the SOX10 gene (MIM* 602229, NM006941.3c.523C > G; p.Pro175Ala) presenting with deafness, depigmentation and progressive neurological impairment. Cells were reprogrammed by non-integrative viral transduction from blood sample, have normal karyotype, express pluripotency markers and are able to differentiate into the three germ cell layers.

Abstract
Mutations in the NPHS2 gene, encoding podocin, are responsible for the majority of familial cases of steroid-resistant nephrotic syndrome (SRNS), a rare glomerulopathy that rapidly progresses to end-stage renal disease. We obtained peripheral blood mononuclear cells (PBMCs) from a patient carrying the homozygous c.413G>A substitution (p.R138Q) in NPHS2 gene, which is the most prevalent mutation in the European population. The PBMCs were reprogrammed by non-integrative viral transduction of the Yamanaka's factors. The resulting iPSCs display normal karyotype, express pluripotency hallmarks and are capable of multilineage differentiation, offering a useful tool to study pathological mechanisms of SRNS and perform drug testing.

Abstract
5-lipoxygenase (5-LO) catalyzes the conversion of arachidonic acid (AA) into pro-inflammatory leukotrienes. N-3 PUFA like eicosapentaenoic acid are subject to a similar metabolism and are precursors of pro-resolving mediators. Stearidonic acid (18:4 n-3, SDA) is a plant source of n-3 PUFA that is elongated to 20:4 n-3, an analogue of AA. However, no 5-LO metabolites of 20:4 n-3 have been reported. In this study, control and 5-LO-expressing HEK293 cells were stimulated in the presence of 20:4 n-3. Metabolites were characterized by LC-MS/MS and their anti-inflammatory properties assessed using AA-induced autocrine neutrophil stimulation and leukotriene B4-mediated chemotaxis. 8‑hydroxy‑9,11,14,17-eicosatetraenoic acid (Δ17-8-HETE) and 8,15-dihydroxy-9,11,13,17-eicosatetraenoic acid (Δ17-8,15-diHETE) were identified as novel metabolites. Δ17-8,15-diHETE production was inhibited by the leukotriene A4 hydrolase inhibitor SC 57461A. Autocrine neutrophil leukotriene stimulation and neutrophil chemotaxis, both BLT1-dependent processes, were inhibited by Δ17-8,15-diHETE at low nM concentrations. These data support an anti-inflammatory role for Δ17-8,15-diHETE, a novel 5-LO product.

Abstract
Proper brain development relies highly on protein N-glycosylation to sustain neuronal migration, axon guidance and synaptic physiology. Impairing the N-glycosylation pathway at early steps produces broad neurological symptoms identified in congenital disorders of glycosylation. However, little is known about the molecular mechanisms underlying these defects. We generated a cerebellum specific knockout mouse for Srd5a3, a gene involved in the initiation of N-glycosylation. In addition to motor coordination defects and abnormal granule cell development, Srd5a3 deletion causes mild N-glycosylation impairment without significantly altering ER homeostasis. Using proteomic approaches, we identified that Srd5a3 loss affects a subset of glycoproteins with high N-glycans multiplicity per protein and decreased protein abundance or N-glycosylation level. As IgSF-CAM adhesion proteins are critical for neuron adhesion and highly N-glycosylated, we observed impaired IgSF-CAM-mediated neurite outgrowth and axon guidance in Srd5a3 mutant cerebellum. Our results link high N-glycan multiplicity to fine-tuned neural cell adhesion during mammalian brain development.

Abstract
Over a decade after their discovery, induced pluripotent stem cells (iPSCs) have become a major biological model. The iPSC technology allows generation of pluripotent stem cells from somatic cells bearing any genomic background. The challenge ahead of us is to translate human iPSCs (hiPSCs) protocols into clinical treatment. To do so, we need to improve the quality of hiPSCs produced. In this study we report the reprogramming of multiple patient urine-derived cell lines with mRNA reprogramming, which, to date, is one of the fastest and most faithful reprogramming method. We show that mRNA reprogramming efficiently generates hiPSCs from urine-derived cells. Moreover, we were able to generate feeder-free bulk hiPSCs lines that did not display genomic abnormalities. Altogether, this reprogramming method will contribute to accelerating the translation of hiPSCs to therapeutic applications.

Abstract
The metabolism of tumors is remarkably different from the metabolism of corresponding normal cells and tissues. Metabolic alterations are initiated by oncogenes and are required for malignant transformation, allowing cancer cells to resist some cell death signals while producing energy and fulfilling their biosynthetic needs with limiting resources. The distinct metabolic phenotype of cancers provides an interesting avenue for treatment, potentially with minimal side effects. As many cancers show similar metabolic characteristics, drugs targeting the cancer metabolic phenotype are, perhaps optimistically, expected to be 'magic bullet' treatments. Over the last few years there have been a number of potential drugs developed to specifically target cancer metabolism. Several of these drugs are currently in clinical and preclinical trials. This review outlines examples of drugs developed for different targets of significance to cancer metabolism, with a focus on small molecule leads, chemical biology and clinical results for these drugs.

Abstract
Huntington's disease (HD) is characterized by a late clinical onset despite ubiquitous expression of the mutant gene at all developmental stages. How mutant huntingtin impacts on signalling pathways in the pre-symptomatic period has remained essentially unexplored in humans due to a lack of appropriate models. Using multiple human embryonic stem cell lines derived from blastocysts diagnosed as carrying the mutant huntingtin gene by pre-implantation genetic diagnosis, we explored early developmental changes in gene expression using differential transcriptomics, combined with gain and loss of function strategies. We demonstrated a down-regulation of the HTT gene itself in HD neural cells and identified three genes, the expression of which differs significantly in HD cells when compared with wild-type controls, namely CHCHD2, TRIM4 and PKIB. Similar dysregulation had been observed previously for CHCDH2 and TRIM4 in blood cells from patients. CHCHD2 is involved in mitochondrial function and PKIB in protein kinase A-dependent pathway regulation, which suggests that these functions may be precociously impacted in HD.

Abstract
Human pluripotent stem cells offer a limitless source of cells for regenerative medicine. Neural derivatives of human embryonic stem cells (hESCs) are currently being used for cell therapy in 3 clinical trials. However, hESCs are prone to genomic instability, which could limit their clinical utility. Here, we report that neural differentiation of hESCs systematically produced a neural stem cell population that could be propagated for more than 50 passages without entering senescence; this was true for all 6 hESC lines tested. The apparent spontaneous loss of evolution toward normal senescence of somatic cells was associated with a jumping translocation of chromosome 1q. This chromosomal defect has previously been associated with hematologic malignancies and pediatric brain tumors with poor clinical outcome. Neural stem cells carrying the 1q defect implanted into the brains of rats failed to integrate and expand, whereas normal cells engrafted. Our results call for additional quality controls to be implemented to ensure genomic integrity not only of undifferentiated pluripotent stem cells, but also of hESC derivatives that form cell therapy end products, particularly neural lines.

Abstract
AIMS/HYPOTHESIS Insulin resistance in skeletal muscle is linked to mitochondrial dysfunction in obesity and type 2 diabetes. Emerging evidence indicates that reversible phosphorylation regulates oxidative phosphorylation (OxPhos) proteins. The aim of this study was to identify and quantify site-specific phosphorylation of the catalytic beta subunit of ATP synthase (ATPsyn-beta) and determine protein abundance of ATPsyn-beta and other OxPhos components in skeletal muscle from healthy and insulin-resistant individuals. METHODS Skeletal muscle biopsies were obtained from lean, healthy, obese, non-diabetic and type 2 diabetic volunteers (each group n = 10) for immunoblotting of proteins, and hypothesis-driven identification and quantification of phosphorylation sites on ATPsyn-beta using targeted nanospray tandem mass spectrometry. Volunteers were metabolically characterised by euglycaemic-hyperinsulinaemic clamps. RESULTS Seven phosphorylation sites were identified on ATPsyn-beta purified from human skeletal muscle. Obese individuals with and without type 2 diabetes were characterised by impaired insulin-stimulated glucose disposal rates, and showed a approximately 30% higher phosphorylation of ATPsyn-beta at Tyr361 and Thr213 (within the nucleotide-binding region of ATP synthase) as well as a coordinated downregulation of ATPsyn-beta protein and other OxPhos components. Insulin increased Tyr361 phosphorylation of ATPsyn-beta by approximately 50% in lean and healthy, but not insulin-resistant, individuals. CONCLUSIONS/INTERPRETATION These data demonstrate that ATPsyn-beta is phosphorylated at multiple sites in human skeletal muscle, and suggest that abnormal site-specific phosphorylation of ATPsyn-beta together with reduced content of OxPhos proteins contributes to mitochondrial dysfunction in insulin resistance. Further characterisation of phosphorylation of ATPsyn-beta may offer novel targets of treatment in human diseases with mitochondrial dysfunction, such as diabetes.

Abstract
Owing to their original properties, pluripotent human embryonic stem cells (hESCs) and their progenies are highly valuable not only for regenerative medicine, but also as tools to study development and pathologies or as cellular substrates to screen and test new drugs. However, ensuring their genomic integrity is one important prerequisite for both research and therapeutic applications. Until recently, several studies about the genomic stability of cultured hESCs had described chromosomal or else large genomic alterations detectable with conventional karyotypic methods. In the past year, several laboratories have reported many small genomic alterations, in the megabase-sized range, using more sensitive karyotyping methods, showing that hESCs are prone to acquire focal genomic abnormalities in culture. As these alterations were found to be nonrandom, these findings strongly advocate for high-resolution monitoring of human pluripotent stem cell lines, especially when intended to be used for clinical applications.

Abstract
OBJECTIVE The Notch pathway plays a key role in cell fate choices and in T-cell development. The goal of our study was to evaluate whether a short in vitro stimulation of the Notch pathway may alter human progenitor cell behavior. METHODS CD34+ cord blood progenitors were exposed for 4 days to either immobilized Notch ligand Delta-4 or in control conditions. Phenotypic and molecular changes induced by the short stimulation were assessed at day 4. Next, long-term alteration of the fate of these progenitors was assessed in culture conditions suitable for B (coculture with MS5 stromal cells) and T (FTOC and OP9 stromal cells expressing Delta-4 systems) cell differentiation. RESULTS Notch activation was sufficient to trigger immunophenotypic and molecular changes consistent with early T-cell lineage differentiation. Delta-4 induced, in 4 days, CD7+cytCD3epsilon+ cells. This paralleled at the gene-transcription level with de novo expression of several T cell-related transcription factors and TCRgamma rearrangement, while B cell transcripts were simultaneous silenced. As compared to non-Delta-4 primed cells, these early changes translated to long-term alteration of the potential of cells. Delta-4 priming led to an acceleration of T-cell development, including a completion of the TCR rearrangement, when cells were cultured in systems suitable for T-cell development while B-cell development was inhibited. CONCLUSION A transient Notch activation is sufficient to promote T-cell differentiation from cord blood CD34+ cells. This system may be a useful tool for the amplification and the quantification of the T potential of CD34+ cells in various disease conditions.

Abstract
Alterations of mitochondrial function may play a central role in neuronal death in Huntington's disease (HD). However, the molecular mechanisms underlying such functional deficits of mitochondria are not elucidated yet. We herein showed that the expression of two important constituents of mitochondrial complex II, the 30-kDa iron-sulfur (Ip) subunit and the 70-kDa FAD (Fp) subunit, was preferentially decreased in the striatum of HD patients compared with controls. We also examined several mitochondrial proteins in striatal neurons that were infected with lentiviral vectors coding for the N-terminus part of huntingtin (Htt) with either a pathological (Htt171-82Q) or physiological (Htt171-19Q) polyglutamine tract. Compared with Htt171-19Q, expression of Htt171-82Q preferentially decreased the levels of Ip and Fp subunits and affected the dehydrogenase activity of the complex. The Htt171-82Q-induced preferential loss of complex II was not associated with a decrease in mRNA levels, suggesting the involvement of a posttranscriptional mechanism. Importantly, the overexpression of either Ip or Fp subunit restored complex II levels and blocked mitochondrial dysfunction and striatal cell death induced by Htt171-82Q in striatal neurons. The present results strongly suggest that complex II defects in HD may be instrumental in striatal cell death.

Abstract
PURPOSE To investigate a role of common polymorphisms of the CYP1B1 gene in French patients with primary open-angle glaucoma (POAG). METHODS Six common CYP1B1 variants, 5 coding and one in promoter, were compared in 224 unrelated French Caucasian POAG patients, excluding those with a CYP1B1 mutation, and in 47 population-matched controls with a normal ophthalmic examination. Allelic associations were assessed with the D' and r2 parameters. An effect of the representative variants on subphenotypes, including the age and the intraocular pressure at diagnosis, the cup to disk ratio, and the visual field alteration, was tested by multivariate analyses. RESULTS Allele and haplotype frequencies were similar in patients and in controls. Five variants formed two groups with tightly correlated alleles while the sixth one, N453S, was independent. The age and the intraocular pressure at diagnosis were not influenced by any of the variants. In contrast, the 453*Serine allele was associated with decreased cupping of the optic disk (Odds ratio=0.32, 95% CI: 0.15-0.70; p=0.0036) and with a milder alteration of the visual field (p=0.025). CONCLUSIONS The common N453S coding variant of CYP1B1 is potentially a factor of severity in POAG patients.

Abstract
INTRODUCTION Primary open-angle glaucoma (POAG) is a leading cause of visual impairment worldwide and a complex genetic disorder that affects mostly adults. Mutations in the MYOCILIN (MYOC) and OPTINEURIN genes account for rare forms with a Mendelian inheritance and for <5% of all POAG cases. The CYP1B1 gene, a member of the cytochrome P450 gene family, is a major cause of primary congenital glaucoma (PCG), a rare and severely blinding disease with recessive inheritance. However, CYP1B1 mutations have also been associated with cases of juvenile-onset glaucoma in some PCG families or shown to modify the age of onset of glaucoma linked to a MYOC mutation in a large family. OBJECTIVE To investigate the role of CYP1B1 mutations in POAG predisposition, irrespective of the presence of a MYOC mutation. METHODS AND SUBJECTS CYP1B1 coding region variation was characterised by denaturing high performance liquid chromatography (DHPLC) and sequencing in 236 unrelated French Caucasian POAG patients and 47 population-matched controls. RESULTS Eleven (4.6%) patients carried one or two mutated CYP1B1 gene(s) and no MYOC mutation. They showed juvenile or middle-age onset of disease (median age at diagnosis, 40 years, range 13-52), significantly earlier than in non-carrier patients. Apart from one, all mutations detected in POAG patients were previously associated with PCG. CONCLUSION CYP1B1 mutations might pose a significant risk for early-onset POAG and might also modify glaucoma phenotype in patients who do not carry a MYOC mutation.

Abstract
In this study we report the molecular and functional characterization of very early interleukin 7 receptor alpha (IL-7Ralpha)+-CD79a+CD19- B-cell progenitors, produced by human CD34+CD19-CD10- cord blood cells grown in the presence of stromal cells and cytokines. Purified IL-7Ralpha+CD79a+CD19- cells transcribed the B-lymphoid specific genes E2A, EBF, TdT, Rag-1, had initiated DJH rearrangements, but almost lacked Pax-5 mRNA. When exposed to appropriate environmental conditions, these cells repressed B-cell genes and completely differentiated into CD14+ macrophages, CD56+ natural killer cells, and CD4high T cells. Retention of the DJH rearranged genes in both CD14+ and CD56+ cells unambiguously demonstrates that early B-cell genes, expressed prior to Pax-5, can be activated in a multipotent human progenitor cell whose final fate, including in non-B lineages, is determined by external signals.
