背景:Stromal derived factors (SDFs) are a loosely defined group of molecules that are generated by stromal cells.
Two of the stromal derived factors, SDF-1 and SDF-4 belong to the chemokine family.
Other SDFs, such as SDF-2 and SDF-5 are not well defined and their biological functions are less known.
SDF-2 is first isolated from themousestromal cell lineST2 as asecretory protein.
The amino acid sequence deduced from themurineclone and thehumanhomologare conserved more than 92 %, and the aa sequence of SDF-2 shows similarity to those ofyeastdolichyl phosphate-D-mannose, protein mannosyltransferases.
SDF-1 and its receptor are strongly indicated in the progression of various cancers including breast cancer.
SDF-2, SDF2-L1, SDF-4, and SDF-5 are ubiquitously expressed in various cancer cell lines and SDF-2, SDF-4 and SDF-5 are expressed in mammary tissues.
These SDFs have prognostic value and warrant further investigation in their biological functions and clinical value.
