Overview
These cells (EcoM-G) exhibit restricted granulocytic differentiation and are useful for studies investigating granulopoiesis and monopoisis. EcoM-G cells are SCF dependent neutrophil progenitor cells that express a conditional form of E2a-Pbx1 in an estrogen responsive manner.
Key elements and design rationale
- Model identity: Immortalized Myeloid Granulocyte Cell Line (ECoM-G) is supplied as an engineered cell line derived from Mouse bone marrow.
- Growth properties: Suspension, round
- Growth conditions: 6 - Well Multiwell Cell Plates (P0100) are recommended for optimal cell culture; passage to new plastic with fresh media at least every 4 days. The base medium for this cell line is PriGrow II (TM002) supplemented with 10% FBS (*Regular) + 10 ng/mL SCF (Z200595) + 0.5 μM ß-estradiol + 1% Penicillin/Streptomycin (G255),37.0°C, 5% CO₂. ß-estradiol is required for cell maintenance but must be completely removed for cell differentiation. Cells are sensitive to post-thaw conditions but recover after 24 hours in culture.For information regarding cell differentiation, please refer to the Differentiation Protocol PDF under the Documents Tab.
- Engineering / immortalization: Gfp reporter expression.
- Product format: Frozen, BSL-2
This cell-based model is generally used in immunology, hematology, and signaling studies. Donor/background information is available for contextual interpretation.

Research relevance and current trends
- Engineered cell lines are widely used for reporter-based readouts, perturbation studies, and assay optimization in reproducible culture systems.
- Reporter or transgene-bearing models are often compared with matched parental or control cells to interpret signal changes in context.
- Expression trends are typically evaluated alongside passage number, selection pressure, and baseline growth behavior.
Common research applications
- Routine expansion and maintenance of a defined cell model for downstream in vitro experiments.
- Phenotype, signaling, or marker-expression studies performed under standardized culture conditions.
- Cell-based assay development in which passage number, growth surface, and medium composition are tracked as experimental variables.
Changes in morphology, growth rate, viability, or reporter signal are typically interpreted together with passage history, culture matrix, and the specified growth conditions for the model.
Notes for experimental interpretation
- Morphology, doubling behavior, and reporter or marker output can shift with passage number, substrate choice, and medium composition; these variables should be recorded alongside experimental readouts.
- Matched controls such as parental cells, untreated cultures, or parallel cultures maintained under identical conditions help distinguish background effects from biology of interest.
Culture and product details
- Growth Conditions: 6 - Well Multiwell Cell Plates (P0100) are recommended for optimal cell culture; passage to new plastic with fresh media at least every 4 days. The base medium for this cell line is PriGrow II (TM002) supplemented with 10% FBS (*Regular) + 10 ng/mL SCF (Z200595) + 0.5 μM ß-estradiol + 1% Penicillin/Streptomycin (G255),37.0°C, 5% CO₂. ß-estradiol is required for cell maintenance but must be completely removed for cell differentiation. Cells are sensitive to post-thaw conditions but recover after 24 hours in culture.For information regarding cell differentiation, please refer to the Differentiation Protocol PDF under the Documents Tab.
- Split Ratio: 1:10-1:20 every 3-4 days
- Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination.
- Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions.
- Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media. Centrifuge cells at 500xg for 5 minutes.
- Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a 6-Well Multiwell Cell Plate.
- Incubate the cells at the recommended conditions.Note: cells are sensitive to recovery from freeze thaw conditions. Therefore, significant cell death may be noted in the initial days post-thawing. However, cells will recover. Performing hemi-depletions of the media may aid in recovery during the initial period. Media and culture vessels must be changed every 4 days.
- Simply add fresh complete media directly to the culture. Do not allow cell density to exceed 1x10⁶ cells/ml.
- Alternatively, replace complete growth media by centrifugation and re-suspend the cell pellet in fresh complete media, and add appropriate aliquots of the cell suspension to new culture vessels, as desired.
- Incubate the cells at the recommended conditions.

How many times can cells divide?
Primary cells have a limited lifespan and will undergo a finite number of population doublings before entering senescence. The exact number varies by cell type and culture conditions.
Immortalized cell lines are capable of extended or indefinite proliferation under proper culture conditions, although growth characteristics may vary between lines.
