Monolayer culture of induced pluripotent stem cells (iPSCs) refers to a standard technique for cell expansion and pluripotency maintenance by adhering cells as a monolayer to the surface of a substrate. Its core lies in standardizing the cultural environment, strict passage control, and quality monitoring. The key points are summarized as follows:
| System Type | Core Configuration | Advantages | Application Scenarios |
|---|---|---|---|
| Feeder-free (Mainstream) | Substrates (Matrigel/recombinant laminin 521) + defined media (E8/StemFlex) | Defined composition, batch stability, and low contamination risk | Routine experiments, clinical-grade cell preparation |
| Feeder-dependent | Mitomycin C-treated MEF feeder layer + conditioned medium | Excellent pluripotency maintenance efficacy | Traditional laboratory settings, specific cell lines |
Substrate Coating
Matrigel is typically diluted with DMEM/F12 at a ratio of 1:100. After coating the culture plates, incubate at 37°C for over 30 minutes, then aspirate the excess solution for later use. Recombinant laminin 521 can be directly diluted for application with higher stability.
Medium Management
In feeder-free systems, E8 medium should be refreshed daily; modified media such as StemFlex can be replaced every two days.
Pre-warm the medium to room temperature before replacement to avoid temperature shock to cells.
Passaging Strategy
Culture Environment
Standard Conditions: 37°C, 5% CO2, saturated humidity. For some cell lines, culture under 5% O2 hypoxic conditions is optional to reduce oxidative stress.
| Problem | Possible Causes | Solutions |
|---|---|---|
| Spontaneous Differentiation | Improper culture conditions, excessive cell density | Optimize medium components, passage cells promptly, and manually remove differentiated areas |
| Low Cell Viability | Excessive dissociation, insufficient seeding density | Shorten dissociation time, adjust seeding ratio, and use ROCK inhibitor |
| Abnormal Colony Morphology | Uneven substrate coating, medium contamination | Recoat the substrate, replace with fresh medium, and strengthen aseptic techniques. |

A: We utilize high-resolution computer vision and daily monitoring of pluripotency markers. By passaging strictly at 70-80% confluency and using non-enzymatic dissociation, we maintain the "primed" pluripotent state without inducing stress-related differentiation.
A: Yes. Our adaptation protocol gradually transitions your cells to recombinant matrices like Vitronectin or Laminin-511, ensuring high survival rates and maintaining the original phenotypic characteristics.
A: All projects are conducted in certified ISO-class cleanrooms. We perform rigorous PCR-based mycoplasma testing and sterility checks at multiple stages of the expansion process.
A: Monolayers provide superior uniformity for drug screening and omics analysis because every cell is exposed to the same microenvironment. EBs are excellent for developmental studies but introduce diffusion gradients that can complicate lead optimization.
A: We offer temperature-controlled shipping of live T-flasks at various stages of confluency to suit your immediate experimental needs.
