摘要： The invention provides novel polynucleotides and polypeptides encoded by such polynucleotides and mutants or variants thereof that correspond to a novel human secreted stem cell growth factor-like polypeptide. These polynucleotides comprise nucleic acid sequences isolated from cDNA libraries prepared from human fetal liver spleen, ovary, adult brain, lung tumor, spinal cord, cervix, ovary, endothelial cells, umbilical cord, lymphocyte, lung fibroblast, fetal brain, and testis. Other aspects of the invention include vectors containing processes for producing novel human secreted stem cell growth factor-like polypeptides, and antibodies specific for such polypeptides.

摘要： A gene encoding a polypeptide having an activity to support proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells is isolated by comparing expressed genes between cells which support proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells and cells which do not support the proliferation or survival. Proliferation or survival of hematopoietic stem cells or hematopoietic progenitor cells is supported by using stromal cells in which the isolated gene is expressed or a gene product of the isolated gene.
