How critical is the Implantation site for the growth kinetics and immune infiltrate of syngeneic breast cancer models<\/a>?<\/p>\n

In our latest study, we tested three different implantation sites, including subcutaneous (SC) on the left flank, and orthotopically into two different mammary fat pad sites (MFP2 and MFP9). Our findings revealed that tumor growth, tumor condition, and tumor viability can all be impacted by the implantation site. We also characterized the composition of the tumor immune infiltrate in both the 4T1 and EO771 syngeneic models and found that the implantation site can affect the balance of the infiltrated immune cells.<\/p>\n

Our conclusion was that tumors grown in the MFP9 implantation site exhibited the best overall growth kinetics, better tumor condition\/viability, and a tumor immune infiltrate richer in B and T lymphocytes in both models. Therefore, the implantation site should be a key consideration when choosing models for the evaluation of therapeutics with different mechanisms of action1.<\/p>\n","protected":false},"excerpt":{"rendered":"

Our study delves into the influence of implantation sites on syngeneic breast cancer models. We uncovered that the choice of site significantly impacts tumor growth, viability, and immune cell composition. Notably, the MFP9 site showed the best outcomes in both 4T1 and EO771 models. This research highlights the importance of considering implantation sites when assessing therapeutics with diverse mechanisms of action.<\/p>\n","protected":false},"featured_media":2685,"template":"","category":[685,751,738,688],"class_list":["post-4012","poster","type-poster","status-publish","has-post-thumbnail","hentry","category-in-vivo-pharmacology","category-oncology","category-oncology-models","category-therapeutic-areas"],"acf":[],"yoast_head":"\nImplantation Site Impact in Syngeneic Breast Cancer Models<\/title>\n<meta name=\"description\" content=\"Review how three implantation sites affected tumor growth, condition, viability and immune infiltrate in EO771 and 4T1 breast cancer models.
