Summary of major macrophage cell sources used in microgravity experiments.
| Cell type | Description |
|---|---|
| Primary macrophages/monocytes | Cells harvested and isolated from living tissue samples, such as blood or immune cell-rich organs (e.g., bone marrow, spleen) |
| RAW 264.7 cells | Murine macrophage-like cell line from an Abelson murine leukemia in BALB/c mice |
| U937 cells | Human leukemic myelomonocytic cell line that differentiates into a macrophage-like phenotype |
| NR8383 cells | Rat alveolar macrophage cell line isolated from lung tissue |
| B6MP102 cells | Murine bone marrow-derived macrophage factor-dependent cell line |
| J-111 cells | Human acute monocytic leukemia cell line, but contaminated with HeLa cells (HPV-related endocervical adenocarcinoma) |
