CT26 (mouse colon cancer)

Pan02 (mouse pancreatic cancer)

B16 (mouse malignant melanoma)

4T1 (mouse breast cacer)

Please note that 4T1 is established from Balb/c mice, while other cancer cell lines are derived from B6 strain.

I have checked the EGFR and HER2 expression in those cancer cell lines, but unfortunately only EGFR is highly expressed in those cell lines.

Despite it is not a mouse model of ovarian adenocarcinoma, the 38C13-HER2/neu murine B cell lymphoma cell line in immunocompetent C3H/HeN mice, expressing stable surface human HER2/neu, should be suitable for your immunotherapeutic approach (attached a useful paper). Otherwise, if the goal is to develop a solid tumor model, I suggest you to use the Her2/neu+ D2F2/e2 tumor cells syngeneic for BALB/c mice (mouse mammary tumor cell lines of epithelial origin; take a look at papers below). TUBO-EGFR may be take into account to develop a mammary tumor in immunocompetent BALB/c mice (nice papers below). Hope these infos are helpful.
