P-88: Comparing Epigenetic Profile of Oct4 Regulatory Region in Embryonal Carcinoma Cells under Retinoic Acid Induction
Background: Embryonal carcinoma (EC) cells derived from germ cell tumors are valuable tools for investigating differentiation and developmental biology processes in vitro. The advantage of the reproducible and rapid expansion of these cell lines provides a useful alternative to embryos for the study of mammalian cell differentiation. During early stages of cell differentiation, the rate of tran...
متن کاملDehydroepiandroesteron increased proliferation of neural progenitor cells derived from p19 embryonal carcinoma stem cells.
Introduction: The p19 line of embryonal carcinoma cells develops into neurons, astroglia and fibroblasts after aggregation and exposure to retinoic acid (RA). Dehydroepiandroesteron (DHEA) is a neurosteroid, can increase proliferation of human neural stem cell (NSC) and positively regulated the number of neurons produced. This study was initiated to assess the effect of DHEA on neural progenito...
متن کاملHypermethylation of human DNA sequences in embryonal carcinoma cells and somatic tissues but not in sperm.
Certain human DNA sequences are much less methylated at CpG sites in sperm than in various adult somatic tissues. The DNA of term placenta displays intermediate levels of methylation at these sequences (Sp-0.3 sequences). We report here that pluripotent embryonal carcinoma (EC) cells derived from testicular germ cell tumors are hypermethylated at the three previously cloned Sp-0.3 sequences and...
متن کاملIdentification and characterization of novel human endogenous retroviral sequences prefentially expressed in undifferentiated embryonal carcinoma cells.
A novel endogenous retroviral sequence (ERV-9) has been isolated from a human embryonal carcinoma cDNA library by hybridization to a probe containing a recently described human repetitive element. DNA sequence analysis of the 4kb cDNA insert (pHE.1) revealed the presence of ORFs potentially coding for putative retrovirus-related gag, pol and env proteins. Northern blot and RNase protection expe...
متن کاملIncreased probability of expression from modified retroviral vectors in embryonal stem cells and embryonal carcinoma cells.
Gene expression from the Moloney murine leukemia retrovirus (Mo-MuLV) is highly restricted in embryonic carcinoma (EC) and embryonic stem (ES) cells. We compared levels of expression in PA317 fibroblasts, F9 (EC) cells, and CCE (ES) cells by Mo-MuLV-based vectors and vectors based on our previously reported MND backbone, which has alterations to address three viral elements implicated as repres...
