Abstract
Tumor microenvironment heterogeneity in hepatocellular carcinoma (HCC) on a spatial single-cell resolution is unclear. Here, we conducted co-detection by indexing to profile the spatial heterogeneity of 401 HCC samples with 36 biomarkers. By parsing the spatial tumor ecosystem of liver cancer, we identified spatial patterns with distinct prognosis and genomic and molecular features, and unveiled the progressive role of vimentin (VIM)high macrophages. Integration analysis with eight independent cohorts demonstrated that the spatial co-occurrence of VIMhigh macrophages and regulatory T cells promotes tumor progression and favors immunotherapy. Functional studies further demonstrated that VIMhigh macrophages enhance the immune-suppressive activity of regulatory T cells by mechanistically increasing the secretion of interleukin-1β. Our data provide deep insights into the heterogeneity of tumor microenvironment architecture and unveil the critical role of VIMhigh macrophages during HCC progression, which holds potential for personalized cancer prevention and drug discovery and reinforces the need to resolve spatial-informed features for cancer treatment.

Two-sided unpaired t-test. n = 3. j, The secretion level of Vimentin detected in indicated status of U937 Ctrl and VIMOE cells. No detected secretion can be observed. n = 3. k, THP1-derived M0 macrophages were treated with conditioned medium from THP1/U937-Ctrl/ VIMOE resting cells. The secretion level of IL-1β was detected. Two-sided unpaired t-test. n = 4. l, Experiments with Tregs directly isolated from PMBCs. Tregs were treated with conditioned medium from THP1-derived M0/M1 macrophages with anti-IL-1β neutralizing antibody/control IgG treatment. The mRNA level (left panel) and the secretion level (right panel) of IL-10 in Tregs were detected upon indicated stimulation. Two-sided unpaired t-test. n = 4 for the left panel and n = 6 for the right panel. m. Representative histogram exhibiting the CFSE signals, related to Fig. 8p. For all panels, n denotes biological replicates for each group. In e-l, data are presented as mean ± SD.
