Sample #170 Liver metastases (from patient with breast cancer)

Overview (Twenty-first microtome cut in a stack of 70 consecutive cuts).

Overview, cut 21  

 

 

The sample was mounted and cut in a cryotome. 70 microtome slices, of 12 μm thickness were cut from the tissue. Every 5th cut was placed on membrane suitable for laser capture microdissection (LCMD), the 4 slices in between were placed on glass slides. A grid of 96 (~25000 μm2) circles was used as a template for the laser capture microdissection on each membrane slide. Pictures of slices and LCMD cuts can be found at the following link.
