| 摘要 |
The invention provides novel polynucleotides and polypeptides encoded by such polynucleotides and mutants or variants thereof that correspond to a novel human stem cell growth factor-like protein. These polynucleotides comprise nucleic acid sequences isolated from cDNA libraries from human fetal liver spleen (Hyseq clone identification number 6118092), ovary (Hyseq clone identification number 8375786), adult brain (Hyseq clone identification numbers 701734, 15327638, 15741682, 15954941, 15955015), lung tumor (Hyseq clone identification number 11047146 and 10280328), spinal cord (Hyseq clone identification number 10102150), cervix (Hyseq clone identification numbers 10022437 and 14029194), ovary (Hyseq clone identification number 8319153), endothelial cells (Hyseq clone identification number 13815744), umbilical cord (Hyseq clone identification number 18568149), lymphocyte (Hyseq clone identification number 10257378), lung fibroblast (Hyseq clone identification number 17116257), fetal brain (Hyseq clone identification number 15266959), and testis. Other aspects of the invention include vectors containing processes for producing novel human stem cell growth factor-like polypeptides, and antibodies specific for such polypeptides.
