摘要:
The present invention discloses transfected embryonic stem cells capable of providing telomerase positive progenitor cells that are capable of proliferation and maintain telomerase gene promoter activity, and to the isolation and propagation of such populations useful for cell replacement therapy. Improvements in cell replacement therapy utilizing such cells form another embodiment of the invention.
摘要:
Methods are provided for producing novel multicellular compositions comprising cancer cells together with pluripotent human stem cells, which are capable of proliferating and differentiating into various normal cell lines and tissue structures. These novel multicellular compositions are useful for investigating the properties of cancer cells in a normal human tissue microenvironment, and for studying interventions that will modulate these properties including devising, testing and screening therapeutic drugs.
摘要:
Provided are methods and kits for determining predisposition of a subject to develop a kidney disease, by identifying in a sample of the subject at least one APOL1 polypeptide variant which is characterized by a higher trypanolytic activity on Trypanosoma brucei rhodesiense as compared to the trypanolytic activity of wild type APOL1 polypeptide as set forth in SEQ ID NO:1 on the Trypanosoma brucei rhodesiense under identical assay conditions; or at least one APOL1 nucleotide mutation in the APLO1 genomic sequence set forth in SEQ ID NO:3, wherein the at least one nucleotide mutation or polypeptide variant being in linkage disequlibrium (LD) with the S342G mutation in the APOL1 polypeptide set forth in SEQ ID NO:1, wherein presence of the APOL1 polypeptide variant indicates increased predisposition of the subject to develop the kidney disease.
