Genome wide expression patterns of 19 human urinary cells as well as 6 primary urinary cells and 17 corresponding iPSCs of human, gorilla and orangutan

ABSTRACT: Comparing the molecular and cellular properties among primates is crucial to better understand human evolution and biology. However, it is difficult or ethically even impossible to collect matched tissues from many primates, especially during development. An alternative is to model different cell types and their development using induced pluripotent stem cells (iPSCs). These can be generated from many tissue sources, but non-invasive sampling would decisively broaden the spectrum of non-human primates that can be investigated. Here, we report the generation of primate iPSCs from urine samples. We first validate and optimize the procedure using human urine samples and show that Sendai virus transduction of reprogramming factors into urinary cells efficiently generates integration-free iPSCs, which maintain their pluripotency under feeder-free culture conditions. We demonstrate that this method is also applicable to gorilla and orangutan urinary cells isolated from a non-sterile zoo floor. We characterize the urinary cells, iPSCs and derived neural progenitor cells using karyotyping, immunohistochemistry, differentiation assays and RNA-sequencing. We show that the urine-derived human iPSCs are indistinguishable from well characterized PBMC-derived human iPSCs and that the gorilla and orangutan iPSCs are well comparable to the human iPSCs. In summary, this study introduces a novel and efficient approach to generate primate iPSCs non-invasively from urinary samples.

Generation of induced pluripotent stem cells from Bornean orangutans

Project description:Bornean orangutans (Pongo pygmaeus) are an endangered non-human primate species. Induced pluripotent stem cells (iPSCs) offer a promising avenue for preserving genetic resources and studying evolutionary processes. In this study, we successfully generate Bornean orangutan iPSCs (o-iPSCs) from peripheral blood mononuclear cells using Sendai virus-mediated reprogramming. Furthermore, we transform primed o-iPSCs into a naïve pluripotent state using a novel 4i/L/A culture system. The resulting naïve o-iPSCs exhibit key features similar to human naïve stem cells, including upregulation of KLF17, DNMT3L, and DPPA3/5. We also observe significant activation of the WNT signaling pathway and X chromosome reactivation in the 4i/L/A o-iPSCs. Transcriptome analysis confirmed their resemblance to human naïve embryonic stem cells. Our findings contribute to the molecular understanding of naïve o-iPSCs and provide a foundation for orangutan conservation using advanced technologies.

RNA-seq of of human (Homo sapiens), gorilla (Gorilla gorilla) and cynomolgus macaque (Macaca fascicularis) iPSC and iPSC-derived NPC cell lines

Project description:RNA-seq samples from 3 species across a differentiation from induced pluripotent stem cells to neural progenitor cells were generated to study gene expression evolution. Briefly, previously generated urinary stem cell derived iPSCs of 3 human (Homo sapiens) individuals (3 clones), 1 gorilla (Gorilla gorilla) individual and fibroblast derived cynomolgus macaque (Macaca fascicularis) iPSCs of 2 individuals (4 clones) (Geuder et al. 2021) were differentiated to neural progenitor cells via dual-SMAD inhibition as three-dimensional aggregation culture (Chambers et al. 2009; Ohnuki et al. 2014). Bulk RNA-seq libraries of iPSCs and NPCs were generated using prime-seq protocol (Janjic et al. 2022).

Urinary Extracellular Vesicles RNA Profile in Clear Cell Renal Cell Carcinoma as Biomarker

Project description:Background: Renal cell carcinoma (RCC) accounts for about 2% of all cancers. Renal biopsy is the gold standard among the diagnostic tools, but it is invasive and not suitable for all patients. Therefore, new reliable and non-invasive biomarkers for ccRCC detection are required. Secretion of extracellular vesicles (EVs), containing RNA molecules that can be transferred between cells, seems to be a general characteristic of malignant transformation. Consistently, cancer-derived EVs are enriched in the blood, urine and various malignant effusions of cancer patients. Therefore, urinary samples can be a non-invasive approach for discovering diagnostic biomarkers. Methods: We enrolled 33 clear-cell RCC (ccRCC) patients and 22 healthy subjects (HS), age and sex-matched, for urine collection and extracellular vesicles isolation by differential centrifugation. Transcriptional profiles of urinary EVs from 12 patients with ccRCC and 11 HS were generated using the Illumina HumanHT-12 v4 BeadChip oligonucleotide arrays. Microarray analysis led to the identification of RNA that were then validated using RT-qPCR. Results: We showed for the first time that urinary exosomal shuttle RNA (esRNA) was significantly different in ccRCC patients compared to HS and we identified three EVs esRNA involved in the tumor biology that are potentially suitable as non-invasive biomarkers. GSTA1, CEBPA and PCBD1 RNA levels decreased in urinary EVs of patients compared to HS. After 1 month post-operation, the levels of RNA increased to reach the normal level. Conclusions: This study suggests, for the first time, the potential use of the RNA content of urinary EVs to provide a non-invasive first step to diagnose the ccRCC. Total RNA obtained from urinary extracellular vesicles isolated from ccRCC patients and healthy subjects.

Nonhuman primate iPSCs and embryonic inner cell mass transcriptome

Project description:Induced pluripotent stem cells (iPSCs) hold promise for generating personalized xenogenic organs via development of cross-species chimeric animals. However, whether human and other primate iPSCs are capable of establishing cross-species chimeras remains unknown. Recognizing the ethical concerns of cross-species chimerism using human iPSCs, we explored the capacity for cross-species chimerism between distinct, non-human primates. Injection of either pig-tailed macaque iPSCs or chimpanzee iPSCs into the rhesus macaque blastocyst embryos demonstrated that these cells survive, proliferate, and integrate near the rhesus inner cell mass (ICM). Ectopic expression of BCL2 in pig-tailed and chimpanzee iPSCs greatly improved the success rate of establishing cross-species blastocyst chimerism. This study represents the first successful cross-species blastocyst chimerism between distinct, non-human primate species, and highlights critical factors that may be necessary to unlock the broad potential of primate iPSCs to form cross-species chimeras, with diverse applications for basic research and translational medicine.

Protein sequence comparison of human and non-human primate tooth proteomes

Project description:In the context of human evolution, the study of proteins may overcome the limitation of the high degradation of ancient DNA over time for providing biomolecular information useful to precise the phylogeny of hominid taxa. Here, we have analysed and compared the tooth proteome of five extant primates (human, gorilla, chimpanzee, orangutan and baboon) using a shotgun proteomics approach. Twenty five proteins were shared by the five datasets, and may be considered as the most representative tooth proteins with a chance of being retrieved from older samples. Some of them were identified by peptides specific to the species, thus allowing to draw up a combinatory panel of peptides with species signature that could be helpful for the taxonomic characterization of ancient samples

Specific normalization of urinary mRNAs reveals genome-wide patterns associated with renal allograft subclinical injury

Project description:urinary mRNA quantification using an Agilent 60k microarray in 26 stable kidney transplant patients with or without renal partial Epithelial to Mesenchymal Transition Subclinical pathological features on the 3-month biopsy of renal allografts predict a poor prognosis, but it is unclear whether surveillance biopsies are beneficial. Non-invasive biomarkers are wanted, and urinary pellet RNA quantification of selected candidate genes has been used with some success do detect overt rejection. We performed a mRNA microarray study using different normalization methods on the urinary cell pellet to evaluate the feasibility of using urine to detect renal partial epithelial mesenchymal transition of the renal allograft (renal pEMT) non-invasively in a group of 26 stable transplanted patients. We found that, when using a novel method of normalization by Upk1a mRNA, renal pEMT of the renal allograft was associated in urine with differential expression of genes belonging to predefined gene sets of kidney-expressed genes and epithelial mesenchymal transition genes. An unbiased pathway analysis revealed that the immune response was the main urinary biological process associated with pEMT in the kidney. In urine from patients with pristine biopsies, pEMT was not associated with inflammation, but with reduced metabolic functions. Thus, we show that pEMT translates into specific UPK1a-normalized mRNA patterns in urine and use genome-wide analyses to characterize underlying molecular patterns, i.e. increased inflammation and decreased metabolic functions.

Identification and comparison of orthologous cell types from primate embryoid bodies shows limits of marker gene transferability

Project description:The foundation of many human-specific traits is likely established during early embryonic development. To understand these molecular processes, we compared gene expression dynamics in embryoid bodies (EBs) differentiated from iPSCs of four primate species: human, orangutan, cynomolgus, and rhesus macaque. We performed scRNA-seq on ∼ 85,000 cells after 8 and 16 days of EB differentiation, identifying diverse cell types across all three germ layers. To accurately compare cell types across species, we developed a semi-automated computational pipeline combining classification and label transfer across clusters to identify orthologous cell types. This approach allowed us to investigate cross-species reproducibility of marker genes, revealing that human markers were less effective in macaques, and vice versa. We found transcription factors to be the most conserved markers, highlighting their potential for cross-species studies. Overall, our study enhances the understanding of conserved and diverged molecular features in early primate development and we provide a well curated cell type reference for future in vitro studies using primates.
