Cells with the unique capacity of self-renewal and potency are called as stem cells.Stem cells undifferentiated pluripotent that can differentiate into specialized a more specific function. Defects ofOral maxillofacial region could be most possibly cured by therapy cells. Through search in PubMed, Google, Scopus Medline, many original research papers were found keywords such cells, pluripotency...
One of the challenges in studying early differentiation of human embryonic stem cells (hESCs) is being able to discriminate the initial differentiated cells from the original pluripotent stem cells and their committed progenies. It remains unclear how a pluripotent stem cell becomes a lineage-specific cell type during early development, and how, or if, pluripotent genes, such as Oct4 and Sox2, ...
Somatic cell nuclear transfer and transcription factor mediated reprogramming are two widely used techniques for somatic cell reprogramming. Both fully reprogrammed nuclear transfer embryonic stem cells and induced pluripotent stem cells hold potential for regenerative medicine, and evaluation of the stem cell pluripotency state is crucial for these applications. Previous reports have shown tha...
It has been debated whether human induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs) express distinctive transcriptomes. By using the method of weighted gene co-expression network analysis, we showed here that iPSCs exhibit altered functional modules compared with ESCs. Notably, iPSCs and ESCs differentially express 17 modules that primarily function in transcription, metabo...
The maintenance of pluripotency in embryonic stem cells (ESCs), its loss during lineage specification or its re-induction to generate induced pluripotent stem cells are central topics in stem cell biology. To uncover the molecular basis and the design principles of pluripotency control, a multitude of experimental, but also an increasing number of computational, studies have been published. Her...
Whether neurons generated in vitro from human embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs) have in vivo-like properties is unknown. In this issue of Neuron, Espuny-Camacho et al. (2013) show that ESC-/iPSC-derived cortical neurons make specific projections and functional synapses when transplanted into a neonatal mouse brain.
Induced pluripotent stem (iPS) cell technology involves the generation of pluripotent stem cells from adult somatic cells by the exogenous expression of specific reprogramming factors (see Box). This technology opened the door for us to access a robust platform demonstrating in vitro cellular reprogramming from certain somatic cells to pluripotent status. Recently, Cahan and Daley conducted a b...
Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...
Studies of the biology of human embryonic stem cells (hES cells) have developed rapidly over the past nine years since the first reports of their derivation. They clearly offer enormous potential, not only for regenerative medicine, but also for drug discovery and toxicology, human developmental biology and cancer research. Realizing these potentials a better understanding of the fundamental as...
