  • Somatic-cell nuclear transfer, the technique by which Dolly was created, was first used 40 years ago in research with tadpoles and frogs. (who.int)
  • if it implants and the pregnancy goes to term, the resulting individual will carry the same nuclear genetic material as the donor of the adult somatic cell. (who.int)
  • RNA sequencing analysis of IRF7 CRISPRa and CRISPRi- DF-1 cells revealed the specificity of CRISPRa and CRISPRi-based targeted transcriptional regulation with minimal off-target effects. (bvsalud.org)
  • If their findings are correct, they may have found substitute cell lines for isolating and studying TSV. (cdc.gov)
  • To confirm their findings, we selected two mammalian cell lines, Hep-2 and Vero, which are highly sensitive to some picornaviruses ( 6 , 7 ), and tested them to determine their susceptibility to TSV. (cdc.gov)
