Dear Histonetters! I was wondering if anyone is working with Desmoplasia markers? I am working with xenograft models (human tumors implanted in mice). So the result is human tumor cells and Murine stroma. I am trying to test various desmoplasia markers found in literature, but almost all of them are for human stroma. So far I got Collagen and Fibronectin working beautifully, but I have problems with the following proteins: alpha Smooth Muscle Actin *Desmin* *GFAP (glial fibrillary actin protein)* *CD 31 (so I'm switching to CD34)* *SPARC* I have a lot of cross-reactivity issues. If anyone knows of antibodies , which are capable of identifying the Murine structures, while keeping the human tissues clean, please let me know. Any information would be highly appreciated! Thank you.
