Project description:Trophoblast stem cells (TSCs), derived from the trophectoderm of the blastocyst, are used as an in vitro model to reveal the underlying mechanisms of placentation in the mammal. In humans, suitable culture conditions for TSC derivation have been recently discovered. The established human TSCs differentiate efficiently toward two trophoblast subtypes, i.e., syncytiotrophoblast (STB) and extravillous trophoblast. On the other hand, the differentiation efficiencies were lower in macaque TSCs compared to human TSCs. Here, we demonstrate that the activation of Wnt signaling induced trophoblastic lineage switching to STB progenitor state. macTSCs highly expressed STB progenitor markers and obtained forskolin responsiveness by CHIR99021 treatment.

Project description:BACKGROUND: In order to contribute to the establishment of a complete map of transcribed regions of the human genome, we constructed a testicular cDNA library for the cynomolgus monkey, and attempted to find novel transcripts for identification of their human homologues. RESULT: The full-insert sequences of 512 cDNA clones were determined. Ultimately we found 302 non-redundant cDNAs carrying open reading frames of 300 bp-length or longer. Among them, 89 cDNAs were found not to be annotated previously in the Ensembl human database. After searching against the Ensembl mouse database, we also found 69 putative coding sequences have no homologous cDNAs in the annotated human and mouse genome sequences in Ensembl.We subsequently designed a DNA microarray including 396 non-redundant cDNAs (with and without open reading frames) to examine the expression of the full-sequenced genes. With the testicular probe and a mixture of probes of 10 other tissues, 316 of 332 effective spots showed intense hybridized signals and 75 cDNAs were shown to be expressed very highly in the cynomolgus monkey testis, but not ubiquitously. CONCLUSIONS: In this report, we determined 302 full-insert sequences of cynomolgus monkey cDNAs with enough length of open reading frames to discover novel transcripts as human homologues. Among 302 cDNA sequences, human homologues of 89 cDNAs have not been predicted in the annotated human genome sequence in the Ensembl. Additionally, we identified 75 dominantly expressed genes in testis among the full-sequenced clones by using a DNA microarray. Our cDNA clones and analytical results will be valuable resources for future functional genomic studies.

Project description:Somatic cell nuclear transfer (SCNT) has been used to clone cynomolgus monkeys (Macaca fascicularis), but the cloning of other non-human primate species remains to be achieved. On the other hand, our histological examination indicated severe calcification of the placenta of SCNT fetuses. Additionally, we found that some of the maternal-biased imprinting genes were aberrantly lost in the cloned embryos by multi-omics analysis. We thus developed a trophoblast replacement (TR) method, providing an ICSI-derived placenta for the SCNT fetus, to support the full-term development of the cloned embryos after implantation. By combining this TR method with treatment with epigenetic modification factors, we obtained a healthy somatic cell cloned rhesus monkey. Thus, TR represents a useful approach for rhesus monkey cloning.

Project description:Precise temporal development is an important event during embryo development. However, transcriptional changes in the temporal development of early epiblast cells (EPI), primitive endoderm (PrE) and trophectoderm (TrB) cells remain unclear. Long terminal repeat elements (LTRs) of ERVs (Endogenous retroviruses) are dynamically expressed in blastocysts of mammalian embryos. However, the expression of LTRs in monkey blastocyst is still unknown. By analyzing publicly available single-cell RNA-sequencing (seq) data, LTRs of several ERV families, including MacERV6, MacERV3, MacERV2, MacERVK1 and MacERVK2 were highly expressed in pre-implantation embryo cells including EPIs, TrB and PrE but absent in post-implantation. We knockdown MacERV6-LTR1a in cynomolgus monkey with short hairpin RNA (shRNA) strategy to examine the potential function of MacERV6-LTR1a in early development of monkey embryo. The silence of MacERV6-LTR1a mainly postpone trophectodermal cell differentiation and cell polarity of TrB, and the genes relate to epithelial proliferation, differentiation and development were downregulated in EPI of shRNA-treated embyos. Addtionally, stem cell differentiation relate genes were downregulated in PrE when MacERV6-LTR1a was silenced. Moreover, we have comfirmed MacERV6-LTR1a can recruit ESRRB (Estrogen Related Receptor Beta). Actually, recent reports demonstrated that ESRRB plays a important role in maintenance of self-renewal and pluripotency of embryonic and trophoblast stem cells through different signaling pathways including FGF and Wnt signaling pathways. In summary, these results suggest that MacERV6-LTR1a potentially regulates the temporal development of pre-implantation embryo of cynomolgus monkey.
