Sample #5 Testicular tumor (Leydig cell tumor)

 Overview of tissue


The sample was snap-frozen in liquid nitrogen within 10 minutes of removal from the patient. The sample was mounted and cut in a cryotome.  24 microtome slices, of 12 μm thickness, were placed on membrane suitable for laser capture microdissection (LCMD). 18 of the 24 slices were subjected to LCMD. A grid of 96 (~25000 μm2) circles was used as a template for the laser capture microdissection on each slide. Pictures of slices and LCMD cuts can be found at the following link.
