Induced pluripotent stem cell-based therapy for treating genetic disorders has become an interesting field of research in recent years. However, there is a paucity of information regarding the applicability of induced pluripotent stem cells in dental research. Recent advances in the use of induced pluripotent stem cells have the potential for developing disease-specific iPSC lines in vitro from...
We describe the use of a characteristic blue fluorescence to identify and isolate pluripotent human embryonic stem cells and human-induced pluripotent stem cells. The blue fluorescence emission (450-500 nm) is readily observed by fluorescence microscopy and correlates with the expression of pluripotency markers (OCT4, SOX2, and NANOG). It allows easy identification and isolation of undifferenti...
Stem cells are a good alternative for regenerative medicine because of their characteristics such as self-renewal and differentiation potential. They are classified into different types of stem cells including embryonic stem cells, induced pluripotent stem cells, multipotent stem cells, and ultimately uni-potent stem cells. Mesenchymal stem cells extracted from adult tissues. Due to the lack of...
On 2 December 2007, Science published a report on creating human induced pluripotent stem (iPS) cells from human somatic cells: ?Induced Pluripotent Stem Cell Lines Derived from Human Somatic Cells.? This report came from a team of Madison, Wisconsin scientists: Junying Yu [5], Maxim A. Vodyanik, Kim Smuga-Otto, Jessica Antosiewicz-Bourget, Jennifer L. Frane, Shulan Tian, Jeff Nie, Gudrun A. Jo...
Cellular reprogramming achieved by somatic nuclear transfer or cell fusion has long been recognized.1 The potency of specific transcription factors as cell fate determinants was first demonstrated by the discovery of MyoD, a master regulator for skeletal muscle differentiation, and by the subsequent identification of several genes as lineageconverting transcription factors in blood cells.2,3 Th...

Mouse embryonic stem cells are continuous cell lines derived directly from the fetal founder tissue of the preimplantation embryo. They can be expanded in culture while retaining the functional attributes of pluripotent early embryo cells. In particular, they can participate fully in fetal development when reintroduced into the embryo. The capacity for multilineage differentiation is reproduced...
Of all known cultured stem cell types, pluripotent stem cells (PSCs) sit atop the landscape of developmental potency and are characterized by their ability to generate all cell types of an adult organism. However, PSCs show limited contribution to the extraembryonic placental tissues in vivo. Here, we show that a chemical cocktail enables the derivation of stem cells with unique functional and ...
The a priori identification of induced pluripotent stem cells remains a challenge. Being able to quickly identify the most embryonic stem cell-similar induced pluripotent stem cells when validating results could help to reduce costs and save time. In this context, tools based on non-classic logic can be useful in creating aid-systems based on visual criteria. True colonies when viewed at 100x m...
A major goal of stem-cell research is to identify conditions that reliably regulate their differentiation into specific cell types. This goal is particularly important for human stem cells if they are to be used for in vivo transplantation or as a platform for drug development. Here we describe the establishment of procedures to direct the differentiation of human embryonic stem cells and human...
