In the following experiments, to identify the effector cells of sGRP78, T, B lymphocytes, and stromal, myeloid cells were isolated from multiple tissues (including tumor, blood, lymph node, and spleen) of E0771 (mCherry or GRP78‐mCherry) tumor bearing mice and were tested for their mCherry‐emitting capacities. Here, HSPA5 is linked to neoplasm.
