Figure 1

Histology of the microdissected tissue samples. (A) Before the removal of the tumor or stroma cell areas, these regions are outlined by the laser beam. Note that samples of pure cell populations were obtained. (B) Following the catapult removal of the samples into collecting vials, the empty spaces of tumor (T) and stroma (S) areas are clearly visible. (Fast red staining, mounted without cover slips; original magnification, × 400.)
