  • Publication number: 20220162563
    Abstract: Disclosed is an in-vitro protocol for differentiating human induced pluripotent stem cells (hiPSCs) or human embryonic stem cells (hESC) to give rise to a definitive endoderm, followed by progression into anteriorized foregut endoderm that has the ability to give rise to both proximal and distal lung epithelial cells. The protocol not only offers great opportunities for the study of human development but also have tremendous potential for future clinical cell-based therapies. The protocol outlined here is used to differentiate hiPSCs into lung epithelial cell types through a process that faithfully recapitulates the stepwise events observed in-vivo. The was followed with the working cell bank of an hiPSC line made under current Good Manufacturing Practice (cGMP) conditions, a necessary step for the future clinical application of these 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.
