Overview
The Immortalized Mouse Urogenital Sinus Mesenchymal Cells (UGSM-2) are derived from a subline of the INK4a mouse, a transgenic knockout that lacks p16INK4a and p19ARF, which are specific inhibitors of cyclin-dependent kinases Cdk4 and Cdk6 that regulate cell cycle progression. UGSM-2 cells display a myofibroblast phenotype in culture with vimentin and smooth muscle actin expression, and is shown to respond to androgen stimulation.
Key elements and design rationale
- Model identity: Immortalized Mouse Urogenital Sinus Mesenchymal Cells (UGSM-2) is supplied as a tumor cell line derived from Mouse embryo.
- Growth properties: Adherent, spindle-shaped and fibroblast-like
- Growth conditions: Use of PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. PriGrow IV (TM004) + 10% FBS(Regular*) + 1% ITS + 2 mM L-glutamine (G275) + 10⁻⁸ M DHT + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂ *Do not heat-inactivate
- Product format: Frozen, BSL-2
This cell-based model is generally used in vascular biology, signaling, and assay development studies. Donor/background information is available for contextual interpretation.
Biological background
Co-culture of UGSM-2 cells with human prostate epithelium cells BPH-1, or co-grafting in vivo results in organized clusters of BPH-1 cells surrounded by a mantle of the UGSM-2 cells. The cells are responsive to Sonic hedgehog (SHH), an important signaling factor in prostate development, and mimic the transcriptional response of the intact UGS mesenchyme. This cell line is a useful model for studying the prostate stroma-epithelium signalling way, which plays an important role in prostate development and cancer progression. Donor/background information provided for this product: p16INK4a and p19ARF Knockout Transgenic Mice.
Research relevance and current trends
- Cell-line models continue to be used for tumor phenotype comparison, pathway perturbation studies, and assay development in controlled in vitro systems.
- Engineered and subtype-defined tumor lines are often used to compare growth behavior, reporter output, and response patterns across matched experimental conditions.
- When metastatic or lineage features are described, investigators commonly interpret results alongside morphology, passage history, and culture environment.
Common research applications
- Cancer biology studies that compare proliferation-associated behavior, morphology, and pathway responses in vitro.
- Assay development for treatment response, reporter monitoring, or phenotype comparison under matched culture conditions.
- Side-by-side comparison of engineered versus parental background characteristics when relevant to the study design.
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: Use of PriCoat™ T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. PriGrow IV (TM004) + 10% FBS(Regular*) + 1% ITS + 2 mM L-glutamine (G275) + 10⁻⁸ M DHT + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂ *Do not heat-inactivate
- Seeding Density (cells/cm²): 15,000 - 20,000
- 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 125xg for 5-7 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 T25 culture flask.
- Incubate the cells at the recommended conditions.
- Aspirate the culture media, and add 2-3ml of pre-warmed 0.25% Trypsin-EDTA to the culture vessel.
- Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37°C, for several minutes to facilitate detachment.
- Neutralize Trypsin-EDTA by adding an equal volume of the complete growth media into the culture vessel.
- Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type.
- Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. 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.
Do I need Applied Cell Extracellular Matrix (G422) if I am using PriCoat™ flasks?
