[Comparative proteome analysis of laser capture microdissection for purified primary tumor and lymph node metastatic tumor in human lung squamous carcinoma].

To search for lymph node metastasis-associated proteins in human lung squamous carcinoma (hLSC).Laser capture microdissection (LCM) was used to purify the target cells from lung primary tumor and matched lymph node metastatic tumor in hLSC. Two-dimensional gel electrophoresis (2-DE) was performed to separate the total proteins of microdissected tumor cells from lung primary tumor and matched lymph node metastatic tumor. PDQuest software was...
