title: Derivation, expansion, and characterization of human embryonic stem cell lines from aneuploid embryos.
abstract: Human embryonic stem cells (hESCs) are an invaluable cell source to study human embryogenesis and development and for exploring the nature of human diseases. Moreover, hESCs can serve as an unlimited source of cells for cell therapy. The first hESC lines were derived from frozen blastocyst-stage embryos. In the past 12 years, the field evolved and the hESC lines are derived from pre-embryos in various developmental stages using several techniques. In parallel, the wide use of hESCs triggered the development of materials and methods for expansion of the cell lines derived. Here, we describe our method for derivation, expansion, and characterization of hESC lines from pre-embryos that were diagnosed to carry aneuploid cells and were destined to be discarded.
