摘要:: Recent evidence indicates that nuclear and cytoplasmic extracts from undifferentiated cells can reprogram gene expression and promote pluripotency in otherwise more developmentally restricted cell types. Notably, extracts of embryonal carcinoma cells or embryonic stem cells have been shown to elicit a shift in the transcriptional program of target cells to upregulate embryonic stem cell genes, downregulate somatic cell-specific markers, and epigenetically modify histones. Reprogrammed kidney epithelial cells acquire a potential for differentiation toward ectodermal and mesodermal lineages. Cell extract-mediated nuclear reprogramming may constitute an attractive alternative to reprogramming somatic cells by cell fusion or nuclear transfer. This review highlights recent observations leading to the concept that extracts derived from pluripotent cells contain regulatory components capable of reprogramming somatic nuclear function. Limitations of current extract-based reprogramming approaches are also addressed.
