Caspase-3 and prox-1 immunoreactivities in H. heilmannii-infected and Flt-4- and Flk-1-administered mice.

a: One week after the administration, many cells within the MALT lymphoma showed positive immunoreactivity against caspase-3.(x200)

b: Three weeks after the administration, the lymphoma became very small and few caspase-3-immunoreactive cells were observed in the lymphoma. (x400)

c-e: In double staining with caspase-3 and prox-1, some of the prox-1-positive cells were found to be caspase-3 immunoreactive (arrow).

c: Prox-1 immunoreactivity, d: caspase-3 immunoreactivity, e: merged view of c and d. (x1000)
