Human iPS cells colonies. The spindle-shaped cells in the background are mouse fibroblast cells. Only those cells comprising the center colony are human iPS cells. Induced pluripotent stem cells (also known as iPS cells or iPSCs) are a type of pluripotent stem cell that can be generated directly from a somatic cell.
Masayo Takahashi (高橋 政代, Takahashi Masayo, born June 23, 1961) is a Japanese medical physician, ophthalmologist and stem cell researcher.. Takahashi serves as a project research leader at the Riken Center for Developmental Biology in Kobe focusing on the clinical application of iPS Cell (induced Pluripotent Stem Cell) technology on macular degeneration.
These pluripotent cells are called iPS (induced pluripotent stem) cells; they appeared with very low frequency. iPS cells can be selected by inserting the b-geo gene into the Fbx15 locus. The Fbx15 promoter is active in pluripotent stem cells which induce b-geo expression, which in turn gives rise to G418 resistance; this resistance helps us ...
Induced pluripotent stem cells (iPS cells) are somatic cells that have been reprogrammed into a stem cell-like state by the introduction of four factors (Oct3/4, Sox2, Klf4, and c-Myc). [36] iPS cells have the ability to self-renew indefinitely and contribute to all three germ layers when implanted into a blastocyst or use in teratoma formation ...
Cell potency is a cell's ability to differentiate into other cell types. [1] [2] The more cell types a cell can differentiate into, the greater its potency.Potency is also described as the gene activation potential within a cell, which like a continuum, begins with totipotency to designate a cell with the most differentiation potential, pluripotency, multipotency, oligopotency, and finally ...
Ten-eleven translocation methylcytosine dioxygenase 1 (TET1) is a member of the TET family of enzymes, in humans it is encoded by the TET1 gene.Its function, regulation, and utilizable pathways remain a matter of current research while it seems to be involved in DNA demethylation and therefore gene regulation, [5] [6] but is expressed as different isoforms which may have distinct functions.
Stem-cell in-vitro. Stem cells could be used as an ideal in vitro platform to study developmental changes at the molecular level. Neural stem cells (NSC) for examples have been used as a model to study the mechanisms behind the differentiation and maturation of cells of the central nervous system (CNS).
