Raji cells were cultured with conditioned media released by either stromal cells on their own (S-CM) or by stromal cells after a 24 h culture with tumour cells (T/S-CM) treated with obinutuzumab for 24 h and the percentage of death for Raji cells cultured either in normal RPMI media or in S-CM (Figure 1K) and T/S-CM (Figure 1L) was measured by labelling cells with 7-AAD/AnnexinV. Here, ANXA5 is linked to neoplasm.
