  • Publication number: 20100068805
    Abstract: The present disclosure provides novel culture system and methods for culturing and propagating hESCs in a substantially undifferentiated state for several passages. The ability to grow such cells without differentiation has important applications for therapeutic uses of ES cells for treating human disorders using tissue transplantation and/or gene therapy techniques. In particular, the disclosure further relates to conditioned medium obtained from human germ lineage derived feeder cells (GLDF). The hESC lines are derived, cultured and propagated in substantially undifferentiated state using the conditioned media from GLDF cells of the disclosure. In particular, the disclosure relates to the xeno-free derivation, culture and propagation of hESCs using conditioned medium of GLDF cells obtained thereof.

  • Publication number: 20100047906
    Abstract: The present disclosure relates to human germ layer derived feeder cells (GLDF cells) and method of generation thereof. Further, it relates to a method for culturing and propagating human embryonic stem cells (hESCs) in a substantially undifferentiated state for several passages on the human GLDF cells. In particular, the present disclosure relates to human GLDF cells which are capable of supporting proliferation of hESCs in a substantially undifferentiated and pluripotent state for several passages.

  • Publication number: 20090253151
    Abstract: The present invention relates to a method for obtaining master adult pluripotent stem (MAPS) cells from adult human corneal epithelial tissues. The MAPS cells are obtained on the basis of pluripotent markers. Further the invention provides MAPS cells that are capable of self renewal and differentiation and have characteristics similar to that of human embryonic stem cells. The MAPS cells also retain the ability to differentiate into cells of different lineages. The composition comprising MAPS cells are useful for therapeutic purposes. Further, the invention provides a culture medium for proliferation of MAPS cells.

  • Publication number: 20080064099
    Abstract: A method of establishing a cell line from the inner cell mass of a blastocyst, comprising: isolating a blastocyst having a zona pellucida, a trophectoderm, and an inner cell mass; creating an aperture in the blastocyst by laser ablation; isolating cells from the inner cell mass from the blastocyst through the aperture; and culturing the cells to establish a cell line, wherein the cells are cultured under feeder free conditions.

  • Publication number: 20070048864
    Abstract: A method for isolating an inner cell mass comprising the steps of immobilizing a blastocyst stage embryo having a zona pellucida, trophectoderm, and inner cell mass, creating an aperture in the blastocyst stage embryo by laser ablation, and removing the inner cell mass from the blastocyst stage embryo through the aperture. The aperture is through the zona pellucida and the trophectoderm. The laser ablation is acheived using a non-contact diode laser. The inner cell mass removed from the blastocyst stage embryo is used to establish human Embryonic Stem Cell lines.

  • Publication number: 20060216821
    Abstract: The present disclosure describes mammalian pluripotent embryonic-like stem cells (ELSCs) isolated from corneal limbal tissue, a non-embryonic tissue. The ELSCs of the present disclosure are capable of proliferating in an in vitro culture, maintain the potential to differentiate into cells of endoderm, mesoderm, and ectoderm lineage in culture, and are capable of forming embryoid-like bodies when placed in suspension culture. Thus, these cells possess multi-lineage differentiation potential and self-renewing capability. ELSCs may be a promising therapeutic tool, and may provide new therapeutic alternatives for various diseases, conditions, and injuries.

  • Publication number: 20060211109
    Abstract: The present disclosure is directed to improved methods for efficiently producing neuroprogenitor cells and differentiated neural cells such as dopaminergic neurons and serotonergic neurons from pluripotent stem cells, for example human embryonic stem cells. Using the disclosed methods, cell populations containing a high proportion of cells positive for tyrosine hydroxylase, a specific marker for dopaminergic neurons, have been isolated. The neuroprogenitor cells and terminally differentiated cells of the present disclosure can be generated in large quantities, and therefore may serve as an excellent source for cell replacement therapy in neurological disorders such as Parkinson's disease.

  • Patent number: 6274788
    Abstract: The present invention relates to a bicistronic DNA construct comprising X-myc transgene. In particular, the present invention relates to a bicistronic X15-myc transgene capable of expressing truncated X protein and a full-length murine c-myc protein. More particularly, the present invention relates to a bicistronic DNA construct being an X15-myc transgene for use in the production of transgenic animal model systems for human hepatocellular carcinoma and transgenic animal model systems so produced. The invention is based partially on the discovery that in susceptible transgenic mice that carry a bicistronic X-myc transgene there is an accelerated formation of liver tumors involving all lobes.
