This video illustrates testing of adjuvant or additional therapy in a mouse model with incompletely resected subcutaneous tumors. The partially tumor-resected mouse is treated with an antibody targeting the anti-cytotoxic protein of T regulatory cells, potentially reducing tumor regrowth and suggesting effective adjuvant therapy.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Inoculation of cells Preparation of cells and animals Ensure that the cell line is maintained in the recommended media. For example, maintain WEHI 164 cell line in Roswell Park Memorial Institute (RPMI) 1640 medium supplemented with 2 mM L-glutamine, 10% fetal bovine serum, 20 mM 4-(2-hydroxyethyl)-1-piperaz…
