Project description:Induction of Pluripotency in Adult Unipotent Germline Stem Cells
| PRJNA115067 | ENA
Project description:Mouse and human stem cells with features similar to those of embryonic stem cells have been derived from testicular cells. Although pluripotent stem cells have been obtained from defined germline stem cells (GSCs) of mouse neonatal testis, only multipotent stem cells have been obtained so far from defined cells of mouse adult testis. In this study we describe a robust and reproducible protocol for obtaining germline-derived pluripotent stem (gPS) cells from adult unipotent GSCs. Pluripotency of gPS cells was confirmed by in vitro and in vivo differentiation, including germ cell contribution and transmission. As determined by clonal analyses, gPS cells indeed originate from unipotent GSCs. We propose that the conversion process requires a GSC culture microenvironment that depends on the initial number of plated GSCs and the length of culture time.

Project description:Oct4-Induced Pluripotency in Adult Neural Stem Cells
| PRJNA112981 | ENA
Project description:Germline stem cells are unipotent stem cells dedicated to differentiate into gemmates throughout of life. However, spontaneous reprogramming of spermatogonial stem cells (SSCs) in long-term culture indicates the acquirement of pluripotency of germ cells affected by microenvironment.epidermal growth factor (EGF), leukemia inhibitory factor (LIF) and fresh mouse embryonic fibroblast (MEF) feeder are essential for transformation, and addition of 2i further enhanced the pluripotency. Transcriptome analysis revealed that EGF activated RAS signaling pathway and inhibited p38 to initiate transformation, and synergically cooperated with LIF to promote the transformation propensity. The increased efficiency of SSCs spontaneous reprogramming established new avenues for regenerative medicine, animal cloning, and research model for germline fate determination.

Project description:Induction of pluripotent stem cells from adult somatic cells by protein-based dedifferentiation
| PRJNA110775 | ENA
Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
