  • Establishment of a human embryonic stem cell line using mammalian cells
    Patent number: 7811817
    Abstract: Purified preparations of human embryonic stem cells with certain population-specific characteristics are disclosed. This preparation is characterized by the positive expression of the following pluripotent cell surface markers: SSEA-1 (?); SSEA-4 (+); TRA-1-60 (+); TRA-1-81 (+); alkaline phosphatase (+), as well as a set of ES cell markers including Oct-4, Nanog, Rex1, Sox2, Thy1, FGF4, ABCG2, Dppa5, UTF1, Cripto1, hTERT, Connexin-43 and Connexin-45. The cells of the preparation are negative for lineage specific markers like Keratin 8, Sox-1, NFH (ectoderm), MyoD, brachyury, cardiac-actin (mesoderm), HNF-3 beta, albumin, and PDX1 (endoderm). The cells of the preparation are human embryonic stem cells, have normal karyotypes, exhibit high telomerase activity and continue to proliferate in an undifferentiated state after continuous culture for over 40 passages.

  • Identifying chromosomal abnormalities in cells obtained from follicular fluid
    Publication number: 20050277147
    Abstract: The present disclosure describes methods for identifying chromosomal abnormalities in cells obtained from follicular fluid to identify, for example, gonadal mosaicism or low-grade gonadal mosaicism. The chromosomal abnormalities are identified using genetic analysis that can detect chromosomal, DNA or gene expression abnormalities in the cells.
