CELLxGENE Get Expression Data
Query gene expression data from CELLxGENE Census (50M+ cells, 60K+ genes). CRITICAL: At least one filter REQUIRED - unfiltered queries timeout. Start with: obs_value_filter='tissue_general == "lung" and disease == "normal"' AND var_value_filter='feature_name in ["TP53", "EGFR"]'. Returns AnnData summary (dimensions, metadata). For full matrix data, use Python API with sufficient memory.
