From: Clinical relevance of B7H3 expression in retinoblastoma
Heterogenous expression of B7H3 in Tumour lobules and Blood vessels. Strong expression in (IRS score=12) tumour lobules with weak expression in blood vessel (a). Strong expression in blood vessel with weak expression of B7H3 in tumour lobule (IRS score = 4(b). Heterogenous expression of B7H3 within the tumour lobule. (IRS score = 9(c), 6(d)). Black arrows indicate blood vessels, Yellow arrows indicate tumor lobules.
