Embryonic stem (ES) cells are used in cell therapy and tissue engineering due to their ability to produce different cells types. However, studies of ES cells that are derived from fertilized embryos have raised concerns about the limitations imposed by ethical and political considerations. Therefore, many studies of stem cells use the stem cells that are derived from unfertilized oocytes and adult tissue. Although parthenogenetic embryonic stem (ESP) cells also avoid ethical and political dilemmas and can be used in cell-based therapy, the ESP cells exhibit growth retardation problems. Therefore, to investigate the potential for muscle growth from genetically modified ESP cells, we established four ES cell types, including normal embryonic stem (ESN) cells, ESP cells, ESP cells that overexpress the insulin-like growth factor 2 (Igf2) gene (ESI) and ESP cells with down-regulated H19 gene expression (ESH). Using these cells, we examined the expression profiles of genes that were related to imprinting and muscle using microarrays. The gene expression patterns of ESI and ESH cells were similar and were more closely related to the ESN pattern than that of the ESP cells. Differentiated ESH cells exhibited increased expression of bone morphologic protein 4 (BMP4), which is a mesoderm marker, compared with the differentiated ESI cells. We showed that Igf2 expression was induced by H19 silencing in the ESP cells via hypermethylation of the H19 imprinting control region 1 (ICR1). Moreover, the proportion of ESH-derived chimera was slightly higher than those produced from the ESP cells. In addition, we detected increased cell proliferation in the MEF cells following H19 knock-down. These results indicate that the ESH cells may be a source of cell-based therapy for conditions such as muscular atrophy.
