Compositions isolated from stromal cells and methods for their use

摘要

Isolated polynucleotides encoding polypeptides expressed in mammalian fsn -/- lymph node stromal cells are provided, together with expression vectors and host cells comprising such isolated polynucleotides. In certain embodiments such polynucleotides encode members of the fibroblast growth factor receptor family. Methods for the use of such polynucleotides and polypeptides are also provided.
