Histological stains for a representative case from each type of tumour. Whole-tumour and details of the tumour and necrotic regions for H&E, TUNEL, and Masson’s trichrome stains are shown, where both the tumour and necrotic regions in the 22Rv1 tumours display higher cell content than their counterparts in the DU145 tumours which, on the other hand, have higher connective tissue content than 22Rv1 tumours.
