Characterisation and quality control: what we measure, what we miss
Characterisation and quality control: what we measure, what we miss

What assays and markers are used to assess stem cell identity and quality. Where current tools fall short: epigenetic stability, functional potency, and subtle state shifts.

Product-market fit in stem cell TechBio: building for workflows, not for papers
Product-market fit in stem cell TechBio: building for workflows, not for papers

Tools built for academic novelty rather than industrial workflows. Microfluidic systems too complex, expensive, slow. How to test whether your product fits real demand.

The regulatory cliff: moving from research-grade to GMP-compliant product
The regulatory cliff: moving from research-grade to GMP-compliant product

Research-grade reagents cannot enter clinical pipelines. GMP, documentation, traceability requirements. The gap between interesting lab tool and regulated product.

Toolchain fragmentation: why imaging, culture, and data systems need to talk to each other
Toolchain fragmentation: why imaging, culture, and data systems need to talk to each other

Imaging, culture, data, and automation systems built in isolation. Manual workflows dominate. Why poor integration limits adoption beyond expert labs.

Cryopreservation and supply chain fragility in clinical-grade cell products
Cryopreservation and supply chain fragility in clinical-grade cell products

Cells lose viability and function after freeze-thaw. Batch variability increases with storage. Critical for clinical trials and commercial supply chains.

Characterisation gaps: what current assays miss about stem cell quality
Characterisation gaps: what current assays miss about stem cell quality

Current assays miss subtle stem cell state shifts. Epigenetic instability, differentiation drift, and what this means for regulatory submissions and clinical outcomes.
