title: Derivation and characterization of three new human embryonic stem cell lines in Finland.
abstract: Human embryonic stem cell (hESC) lines can be established from the preimplantation embryos. Due to their ability to differentiate into all three embryonic layers, hESC are of significant interest as a renewable source of cell material for different applications, especially for cell replacement therapy. Since the establishment of the first hESC lines in 1998, several studies have described the derivation and culture of new hESC lines using various derivation methods and culture conditions. Our group has currently established eight new hESC lines of which three of the latest ones are described in a more detailed way in this report. The described lines have been established using mechanical derivation methods for surplus bad quality embryos and culture conditions containing human foreskin fibroblast feeder cells and serum-free culture medium. All the new lines have a normal karyotype and typical hESC characteristics analyzed in vitro. The described hESC lines are available for research purposes upon request (www.regea.fi).
