Overview
Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) is a hematopoietic cytokine that regulates the proliferation, survival, differentiation, and activation of myeloid lineage cells. It promotes the development of granulocytes, monocytes, macrophages, and dendritic cells from hematopoietic progenitors.
In cell culture, GM-CSF is widely used for dendritic cell generation, macrophage differentiation, myeloid cell culture, hematopoietic stem cell research, and immunology applications.
Biological Function
GM-CSF regulates numerous biological processes, including:
- Promotes myeloid progenitor proliferation
- Supports granulocyte differentiation
- Stimulates macrophage development
- Drives dendritic cell differentiation
- Enhances cell survival
- Activates innate immune cells
- Regulates inflammatory responses
Mechanism of Action
GM-CSF binds to the GM-CSF receptor, composed of:
- GM-CSFRα (CD116)
- Common β chain (βc/CD131)
Receptor activation induces intracellular signaling through:
- JAK2-STAT5 pathway
- PI3K-AKT pathway
- MAPK/ERK pathway
- NF-κB pathway
These pathways regulate proliferation, differentiation, activation, and survival of myeloid cells.
Common Applications
GM-CSF is widely used for:
- Dendritic cell generation
- Macrophage differentiation
- Myeloid cell culture
- Hematopoietic stem cell culture
- Bone marrow cell culture
- Immunotherapy research
- Vaccine development
- Leukemia research
Cell Types Commonly Supplemented with GM-CSF
| Cell Type | Typical Application |
|---|---|
| Bone Marrow Cells | Myeloid differentiation |
| Hematopoietic Stem Cells (HSCs) | Myeloid lineage expansion |
| CD34⁺ Cells | Myeloid differentiation |
| Monocytes | Dendritic cell generation |
| Macrophage Precursors | Differentiation |
| Dendritic Cells | Generation and maturation |
| Human iPSCs | Myeloid differentiation |
| Human ESCs | Hematopoietic differentiation |
GM-CSF is frequently combined with additional cytokines depending on the desired myeloid lineage.
Typical Working Concentrations
| Application | Typical Concentration |
|---|---|
| Dendritic Cell Differentiation | 25-100 ng/mL |
| Macrophage Differentiation | 10-50 ng/mL |
| Hematopoietic Stem Cell Culture | 10-50 ng/mL |
| Myeloid Cell Expansion | 10-50 ng/mL |
