Figure 4From: Macrodissection versus microdissection of rectal carcinoma: minor influence of stroma cells to tumor cell gene expression profilesSchematic overview of the strategy used to compare macrodissection and microdissection. All 14 rectal carcinoma samples are macrodissected or microdissected for tumor epithelium, 6 macrodissected samples were in addition amplified (amp) a second round and of 4 samples the stroma was microdissected as well.Back to article page
