Pluripotent stem cells would have great potential in cell therapies and drug development when genetically matched with the patient; thus, histocompatible cells could be used in transplantation therapy or as a source of patient-specific cells for drug testing. Pluripotent embryonic stem cells (ESCs)-generated via somatic cell nuclear transfer (SCNT) or parthenogenesis (pESC)-are potential sources of histocompatible cells and tissues for transplantation. Earlier studies used the piezoelectric microinjection (PEM) technique for nuclear transfer (NT) in mouse. No specific studies examined zona-free (ZF) NT as an alternative NT method to generate genetically matched ESCs of a nuclear donor. In this study, we compared the efficiency of nuclear transfer-derived ESC (ntESC) line establishment from ZF-NT, ZF-parthenogenetic (PGA), and ZF-fertilized embryos with that of the PEM-NT method. Different nuclei donor cells [cumulus, ESC, and mouse embryonic fibroblast (MEF)] were used and the efficiency of ntESC derivation was investigated, along with their in vitro characterization. The ZF-NT method's efficiency was higher than that of the PEM-NT using cumulus cells. When ESCs and cumulus cells were used as nuclear donor cells, they resulted in significantly higher ZF-NT-derived ntESC line establishment rates compared to MEF cells. In conclusion, the nuclear donor cell type significantly affected the efficiency of ntESC line establishment, and the ZF-NT method was efficient to establish pluripotent ntESC lines.

D008815 Mice, Inbred Strains Genetically identical individuals developed from brother and sister matings which have been carried out for twenty or more generations, or by parent x offspring matings carried out with certain restrictions. All animals within an inbred strain trace back to a common ancestor in the twentieth generation.

D002460 Cell Line Established cell cultures that have the potential to propagate indefinitely. Cell Lines,Line, Cell,Lines, Cell
D002467 Cell Nucleus Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed) Cell Nuclei,Nuclei, Cell,Nucleus, Cell
D004622 Embryo, Mammalian The entity of a developing mammal (MAMMALS), generally from the cleavage of a ZYGOTE to the end of embryonic differentiation of basic structures. For the human embryo, this represents the first two months of intrauterine development preceding the stages of the FETUS.

D004624 Embryo Transfer The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
