Human Sarcoma Peripheral Blood Mononuclear Cells

Description

Human Sarcoma Peripheral Blood Mononuclear Cells (PBMCs) are isolated from patients with various sarcoma subtypes, including osteosarcoma, Ewing sarcoma, leiomyosarcoma, and liposarcoma, providing researchers with a critical tool to study the complex immune response in these rare and aggressive malignancies. These PBMCs contain immune cell populations (T cells, B cells, NK cells, and monocytes) that reflect sarcoma-specific immune alterations, including elevated Tregs (CD4⁺CD25⁺FoxP3⁺), increased PD-1⁺ exhausted T cells, and tumor-associated macrophages (TAMs). Sarcoma-associated PBMCs may also show defective antigen presentation capacity in monocytes and dendritic cells, further compromising anti-tumor immunity. These immune abnormalities correlate with disease progression and therapeutic resistance, highlighting their role in sarcoma pathogenesis. These cells are valuable for pbmc phenotyping sarcoma, detecting autoimmune markers in sarcoma, monitoring sarcoma progression, and enabling standardized pbmc isolation sarcoma for immunological studies and therapeutic evaluation.
