Tumors Harvested and Digested for Flow Cytometry Were Analyzed for CD11b, Ly6C, F4/80, and CD206 Expression.

	Intratumoral Macrophages	F4-80hi/CD206hi	F4-80hi/CD206lo	Ratio
Control	15.2% (1.3)	41.2%	26.9%	0.7
Cis	31.1% (3.0)	33.5%	22.5%	0.7
PS	23.8% (2.8)	24.7%	31.2%	1.3
Combination	46.5% (6.9)	18.3%	38.3%	2.1

F4/80 is a macrophage activation marker, CD206 is the macrophage mannose receptor, and their expression suggests a protumor phenotype.

Values in parentheses are SDs.
