    made concerning embryonic stem-cell research simply because the two sides, supporting and not, will most likely never see eye-to-eye. Embryonic stem-cells may not be the only source of pluripotent cells that science can find. Some of the keys to pluripotency have been discovered, although in a very limited fashion. Steve Mitchell writes about this in “Adult Stem Cells Potential

    Stem Cell Research What is a Stem Cell? Stems cells are immature cells found in embryos that can develop into any kind of specialized cells. They can form virtually any cell of the human body. These types of stem cells are known as pluripotent cells. Multipotent cells are stem cells that are more mature; they can be found in adults and children. Multipotent cells are not as flexible as pluripotent cells, as they have already developed into more specialized human cells. Benefits of Stem

  • Role in Inducing and Maintaining the Pluripotency of Mice Embryonic Stem Cells

    Several members of the zinc finger family of proteins are key components in the transcriptional network maintaining pluripotency in embryonic stem cells. The mouse zinc finger protein 322a (Zfp322a) is expressed in embryonic stem cells and the ICM. Thus Ma et al. 2014 hypothesized that Zfp322a functions as a transcription factor in mice. Ma et al. (2014) discovered that Zfp322a is an irreplaceable transcription factor which enhances the reprogramming ability of OKSM (Oct4,  Klf4, Sox2, and c-Myc)

    Factors” ¬Stem cells are yet undifferentiated cells, with the potential capability to further divide indefinitely, and the ability to give rise to more specialized cell types. Embryonic stem(ES) cells are of especially great importance due to their pluripotency and hence ability to differentiate to cells of all three germ layers. Due to the great replicative powers of these cells, they may be used to treat degenerative diseases, or injuries to the nervous system. However, as these ES cells are extracted

    These cells only carry a heterozygous splicing mutation (c.204+1G>A) in the NF1 genome and with the other allele remaining wildtype (Nf1+/-). (D-I) are immunofluorescence assay to characterize the pluripotency of Nf1+/- iPS cells using a panel makers for human embryonic stem cells. (A) and (B) are patient neurofibroma-derived fibroblasts and iPS cells before and after reprogramming. The generated iPS cells maintain classic clonal growth in both feeder-dependent

    pipette tip. The cells were then evenly distributed among the wells and placed in the incubator. Immunocytochemistry (ICC): By linking antibodies to fluorophores, ICC was used to determine the expression of the transcription factors that indicate pluripotency(OCT4, SOX2, NANOG, SSEA4). . Following 3-4 days after the third passage, the medium was removed from all the wells and fixed with 4% paraformaldehyde (PFA). Next, primary antibodies were added and left to sit overnight. Following immunostaining

    most promising sources for organ regeneration Achieving Induced Pluripotency in Adult Somatic Cells Pluripotent stem cells include embryonic stem cells and induced pluripotent stem cells. Embryonic stem cells are highly controversial and difficult to obtain, which impedes any research and treatment using embryonic stem cells. Takahashi and Yamanaka circumvented this issue, in 2006, by achieving artificial induction of pluripotency in adult stem cells. Adult stem cells, which have restricted differentiation

    reference, it will describe the process of discovery and modern application of induced pluripotent stem cells, leaning heavily on the original work of Shinya Yamanaka of Kyoto University, who was awarded a Nobel Prize for her role in discovering adult pluripotency. Finally, it will take a forward perspective to predict how this technology may be used in the future of medicine and discuss some of the most controversial ethical questions regarding these potential uses. In 1981, Martin Evans of the

    extraembryonic tissues are deemed ‘pluripotent’. Induced cells that are in a differentiable state, pluripotent, are the cells chosen to advance medicine. Cells selected for induced pluripotency cannot be terminally differentiated, as these cells lose their ability to be developed into other cells types (14). Pluripotency can be induced by the study of embryonic stem cells. These cells express factors (Oct3/4, Sox2, Klf4, c-Myc), deemed Yamanaka factors (15) and described as such in this review. There

  • The Hallmarks Of A Stem Cell

    The hallmarks of a stem cell are its ability to self-renew as well as its ability to differentiate and assume almost any cell fate if given the appropriate cues known as pluripotency (ref). The differentiation of stem cells requires large and rapid changes in gene expression. miRNAs are well suited to carry out this task through their ability to simultaneously inhibit the translation of several target genes allowing for coordinated control of cellular processes{Bartel:2009fh}. Furthermore, miRNAs
