Fig. S1. Expansion of CD11b+Gr1

+ cells during tumor progression in PyMT mice.

(A-B), Tissues from tumor-bearing PyMT and WT mice were collected and analyzed by FACS.

Cells from WT (A) and PyMT (B) mice were gated on CD45+ and analyzed using CD11b/Gr1

to identify neutrophils/monocytes, which expanded significantly during tumor progression in

bone marrow, blood, spleen, lung, brain and tumor compared to WT. (C) Combined

quantification of FACS results including statistical analysis is shown in bar graphs unpaired t-

test (Mean ± SEM of n =3) *P< 0.05. (D-E) Spleen from tumor-bearing PyMT (14 weeks) was

enlarged compared to WT.

Fig. S2. MDSCs emerge predominantly in spleen of tumor-bearing mice.

(A) Experimental overview. Bone marrow, spleen and lung were processed into single cell

suspensions and (sytox blue-negative) CD45+CD11b

+Gr1

+ cells were sorted and subjected to

functional T cell suppression and ROS formation assays. (B-C) Splenic CD11b+Gr1

+ cells from

tumor-bearing mice suppress T cell proliferation. Histogram overlay (B) and quantitative bar

charts (C) showing CD4/CD8 T cell proliferation measured by FACS. (D-E), Bone marrow-

derived CD11b+Gr1

+ cells from tumor-bearing mice show non-significant suppression of T cell

activation. (F-G) CD11b+Gr1

+ cells were sorted from tumor-bearing mouse lungs and co-

cultured with activated T cells showed no effect in T cell proliferation. (H-I), ROS formation in

CD11b+Gr1

+ cells from tumor-bearing and control mice. PMA-treated cells were used as

positive control. ROS was measured by FACS using H2DCFDA in CD11b+Gr1

+ cells from

bone marrow, spleen, and lung from control and tumor-bearing mice. (C-I) Statistical analysis

unpaired t-test (Mean ± SEM of n = 3) *P< 0.05. ns = not significant. Color labels (B-G) in

control samples, T cells (red) activated by CD3/CD28 (blue), activated T cells plus

CD11b+Gr1

+ cells from control spleens or bone marrow (orange) and activated T cells plus

CD11b+Gr1

+ cells from spleen, bone marrow or lung of tumor-bearing mice (green).

monocytes only from WT and tumor-bearing PyMT mouse spleens shown in tSNE projection

labeled by tissue source. (WT = blue; PyMT = red). (C-D) Heatmaps of Top 10 upregulated

genes of all clusters in of combined Seurat analysis including G-MDSC cluster C2 (C) and

subset monocyte analysis (D) in all monocyte clusters including M-MDSC cluster M2. (E-F)

Membership pie charts demonstrated clusters belong to WT or PyMT.

Fig. S4. CD84 is a generalizable MDSC marker in different breast cancer models.

(A-B) FMO and isotype controls were used to determine CD84 and JAML expression. (C-D)

Tissues from 4T1 breast cancer models and WT mice were collected and processed to single cell

suspensions. Cells were stained with antibodies for CD45+CD11b
