Detection of testicular leukemia model mice. HE staining: a In normal C57BL/6 mice, a large number of spermatogenic cells and sperm cells could be seen in testis tissue. b In the model group, after 104 cells were injected to establish the model for 3 weeks, spermatogenic cells and sperm cells in the testis tissue decreased with the infiltration of BALL cells. Immunohistochemistry: c In normal C57BL/6 mice, the expression of CD20 protein in testicular tissue was negative. d In the model group, a large number of CD20-positive BALL cells infiltrated into the seminiferous tubule, spermatogenic cells and sperm cells in the testis tissue decreased. e Negative control. Scale bar = 100 μm
