Deciphering the stem cell machinery as a basis for understanding the molecular mechanism underlying reprogramming Bosnali M; Munst B; Thier M; Edenhofer FCell Mol Life Sci 2009[Nov]; 66 (21): 3403-20Stem cells provide fascinating prospects for biomedical applications by combining the ability to renew themselves and to differentiate into specialized cell types. Since the first isolation of embryonic stem (ES) cells about 30 years ago, there has been a series of groundbreaking discoveries that have the potential to revolutionize modern life science. For a long time, embryos or germ cell-derived cells were thought to be the only source of pluripotency--a dogma that has been challenged during the last decade. Several findings revealed that cell differentiation from (stem) cells to mature cells is not in fact an irreversible process. The molecular mechanism underlying cellular reprogramming is poorly understood thus far. Identifying how pluripotency maintenance takes place in ES cells can help us to understand how pluripotency induction is regulated. Here, we review recent advances in the field of stem cell regulation focusing on key transcription factors and their functional interplay with non-coding RNAs.|Animals[MESH]|Cell Differentiation/genetics/*physiology[MESH]|Cellular Reprogramming/genetics/*physiology[MESH]|Gene Expression Regulation, Developmental[MESH]|Humans[MESH]|Models, Biological[MESH]|Octamer Transcription Factor-3/genetics/metabolism[MESH]|Signal Transduction/genetics/physiology[MESH]|Stem Cells/metabolism/*physiology[MESH]|Transcription, Genetic/physiology[MESH] |
