Immunohistochemical analysis.

Representative immunohistochemical stainings for microvascular density (CD-31, A and B), apoptosis (TUNEL, C and D), and proliferation (Ki-67, E and F) in the therapy (right) and control group (left). Note the lower number of CD-31 and Ki-67 positive cells (stained in brown, B and F) and the higher number of cells positive for TUNEL (stained in fluorescent green, D) in the therapy group.
