M2-10B4 Cells

The M2-10B4 cell line is a clone derived from bone marrow stromal cells from a (C57BL/6J X C3H/HeJ)F1 mouse. These stromal cells are essential components of the bone marrow microenvironment and play a significant role in supporting hematopoiesis. The M2-10B4 cells are particularly valuable for research focused on the interactions between stromal and hematopoietic cells, as they can support both human and murine myelopoiesis in long-term culture. Additionally, these cells can sustain certain murine stromal cell-dependent pre-B cell lines in vitro, making them a versatile tool in hematopoietic research. The M2-10B4 cells express important extracellular matrix components such as laminin and collagen IV, which contribute to their ability to support hematopoietic cells. However, they do not express collagen I or Factor VIII, which distinguishes them from other stromal cell lines. The presence of laminin and collagen IV is critical for the maintenance of the bone marrow microenvironment, influencing cell adhesion, differentiation, and signaling pathways. Researchers often utilize the M2-10B4 cell line in co-culture systems to explore the effects of stromal cells on the behavior of hematopoietic progenitors, particularly in the context of bone marrow physiology and disease models. Given their origin and functional properties, M2-10B4 cells are an essential model for studying the bone marrow niche, especially in relation to hematological disorders such as leukemia. They are also useful in drug screening and the development of therapeutic strategies targeting the bone marrow microenvironment.
