Project description:Induced pluripotent stem cells (iPSCs) can provide biological resource for functional and conservation research for various species. However, the understanding of species variations of mammalian iPSCs is still limited. Here, we report the first generation of iPSCs from the endangered species Grevy's zebra (Equus grevyi; gz-iPSCs). We reprogram primary fibroblasts with human reprogramming transcription factors, OCT3/4, SOX2, KLF4, and c-MYC, with the retroviral method and confirmed the pluripotency and differentiation potential. In light of RNA sequencing analysis, generated gz-iPSCs robustly express genes associated with pluripotency and reprogramming processes, including epithelial-to-mesenchymal and mesenchymal-to-epithelial transitions (EMT-MET). Comparative transcriptomics with other species reveals patterns of gene expressions among mammalian PSCs and detects evolutionary conservation of pluripotency-associated genes and plausible importance of translation process. This work will aid in providing biological resource for this endangered species and enables new insight into the evolution of the mammalian PSCs.
Project description:EBV immediate early protein ZEBRA was corroborated to interact with Pax5 which controls the fate of B cells. Ramos cells were infected with ZEBRA-expression lentivirus and positively infected cells were sorted, which were named Ramos-Lv-ZEBRA.
