Nonhuman primate iPSCs and embryonic inner cell mass transcriptome

ABSTRACT: 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.

Chromosome-level de novo assembly and annotation of pig-tailed (macaca nemestrina) macaque genome

Project description:Macaque species share over 93% genome homology with humans and develop many disease phenotypes similar to those of humans, making them valuable animal models for the study of human diseases (e.g.,HIV and neurodegenerative diseases). However, the quality of genome assembly and annotation for several macaque species lags behind the human genome effort. To close this gap and enhance functional genomics approaches, we employed a combination of de novo linked-read assembly and scaffolding using proximity ligation assay (HiC) to assemble the pig-tailed macaque (Macaca nemestrina) genome. This combinatorial method yielded large scaffolds at chromosome-level with a scaffold N50 of 127.5 Mb; the 23 largest scaffolds covered 90% of the entire genome. This assembly revealed large-scale rearrangements between pig-tailed macaque chromosomes 7, 12, and 13 and human chromosomes 2, 14, and 15. We subsequently annotated the genome using transcriptome and proteomics data from personalized induced pluripotent stem cells (iPSCs) derived from the same animal. Reconstruction of the evolutionary tree using whole genome annotation and orthologous comparisons among three macaque species, human and mouse genomes revealed extensive homology between human and pig-tailed macaques with regards to both pluripotent stem cell genes and innate immune gene pathways. Our results confirm that rhesus and cynomolgus macaques exhibit a closer evolutionary distance to each other than either species exhibits to humans or pig-tailed macaques. These findings demonstrate that pig-tailed macaques can serve as an excellent animal model for the study of many human diseases particularly with regards to pluripotency and innate immune pathways.

Epigenomic annotation of gene regulatory alterations during evolution of the primate brain

Project description:While genome sequencing has identified numerous non-coding alterations between primate species, which of these are regulatory and potentially relevant to the evolution of the human brain is unclear. Here, we annotate cis-regulatory elements (CREs) in the human, rhesus macaque and chimpanzee genome using ChIP-sequencing in different anatomical parts of the adult brain. We find high similarity in the genomic positioning of CREs between rhesus macaque and humans, suggesting that the majority of these elements were already present in a common ancestor 25 million years ago. Most of the observed regulatory changes between humans and rhesus macaque occurred prior to the ancestral separation of humans and chimpanzee, leaving a modest set of regulatory elements with predicted human-specificity. Our data refine previous predictions and hypotheses on the consequences of genomic changes between primate species, and allow the identification of regulatory alterations relevant to the evolution of the brain. ChIP-Sequencing for H3K27ac on 8 distinct brain regions from human (three biological replicates per brain region), chimpanzee (two biological replicates per brain region) and rhesus macaque (three biological replicates per brain region).

Generation of functional rat spermatozoa in sterile mice utilizing blastocyst complementation with pluripotent stem cells [scRNAseq_chimera]

Project description:Pluripotent stem cells (PSCs) provide a powerful tool to produce transgenic animals for biomedical research. However, impaired PSC contribution to chimerism and most notably the germline oftentimes impedes production of genetically modified animals, rendering techniques that expediate PSC contribution to the germline highly desirable. Blastocyst complementation denotes a technique which purposes to generate organs, tissues or cells in animal chimeras via microinjection of PSCs into genetically compromised blastocyst-stage embryos. Here we report on successful blastocyst complementation of the male germline in adult chimeras following microinjection of mouse or rat PSCs into mouse blastocysts mutated for Tsc22d3, an essential gene for spermatozoa production. Microinjection of mouse embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs) into Tsc22d3-KnockOut (KO) blastocyst-stage embryos gave rise to intraspecies chimeras embodying functional spermatozoa, which were solely derived from microinjected PSCs. Furthermore, microinjection of rat ESCs into Tsc22d3-KO mouse embryos gave rise to viable mouse-rat chimeras that exhibited extensive contribution of rat cells to various organs. Notably, multiple mouse-rat chimeras showed contribution of rat ESCs to the male germline, solely harboring rat spermatids and spermatozoa that were rat ESC-derived and could fertilize rat oocytes. Collectively, this study reports a method for exclusive production of functional germ cells of one species in another via blastocyst complementation with PSCs. Implications of this study extend to development of transgenic rats via sterile mice, and may further assist efforts to generate xenogeneic gametes from endangered animal species.

Extensive Evolutionary Changes in Regulatory Element Activity during Human Origins Are Associated with Altered Gene Expression and Positive Selection [Dnase-seq]

Project description:The human genome shares a remarkable amount of genomic sequence with our closest living primate relatives. Researchers have long sought to understand what regions of the genome are responsible for unique species-specific traits. Previous studies have shown that many genes are differentially expressed between species, but the regulatory elements contributing to these differences are largely unknown. Here we report a genome-wide comparison of active gene regulatory elements in human, chimpanzee, and macaque, and we identify hundreds of regulatory elements that have been gained or lost in the human or chimpanzee genomes since their evolutionary divergence. These elements contain evidence of natural selection and correlate with species-specific changes in gene expression. Polymorphic DNA bases in transcription factor motifs that we found in these regulatory elements may be responsible for the varied biological functions across species. This study directly links phenotypic and transcriptional differences between species with changes in chromatin structure. One biological replicate was analyzed for each of the 15 primate samples using DNase-seq.

Single cell RNA-seq of great ape cerebral organoids

Project description:The human brain has changed dramatically from other primate species, but the genetic and developmental mechanisms behind the differences remains unclear. Here we used single cell RNA sequencing based on 10X technology to explore temporal transcriptomic dynamics and cellular heterogeneity in cerebral organoids derived from human and non-human primates chimpanzee and rhesus macaque stem cells. Using cerebral organoids as a proxy of early brain development, we detect a delayed pace of human brain development relative to the other two primate species. Additional human-specific gene expression patterns resolved to different cell states through progenitors to neurons are also found. Our data provide a transcriptomic cell atlas of primate early brain development, and illustrate features that are unique to humans.
