What if the real obstacle in 3D cell culture and tissue engineering isn't the cells, but the very ground they grow on?
For years, cell culture has relied on flat plastic and passive scaffolds. But biology doesn't happen on a petri dish—cells live in three dimensions, surrounded by a dynamic environment that talks back, adapts, and shapes development in ways static gels simply cannot.
That's the premise behind MosaMatrix, a novel hydrogel platform designed to transform how we grow cells, engineer tissues, and screen new drugs created by CEO Jan Hunik and CTO Matt Baker.
Topics discussed:
Why traditional flat, 2D cell culture misses the biological mark and what a responsive cell environment really looks like (00:27)
The origins of MosaMatrix and the realization that new, adaptive hydrogels were needed for dynamic cell culture (04:45)
What makes the MosaMatrix hydrogel different—and why passive scaffolds fall short (06:12)
Mechanical and biological characteristics that define hydrogel performance, from stiffness to stress relaxation (07:48)
The company's pivot from 3D tissue printing to focusing on high-throughput 3D cell culture for drug discovery (08:42)
Advantages of a non-animal-derived, reproducible matrix for research and industry (10:20)
Strategies for obtaining real-world customer feedback and working in consortia with academia and industry partners (11:51)
Key hurdles in quality control, reproducibility, and measuring success in the emerging field (16:05)
Challenges with standardizing organoids and the move to smaller, more automatable culture systems (17:50)
The impact of automation and data consistency for scaling up 3D cell culture (18:14)
Smart insight: MosaMatrix validates its hydrogel not through internal R&D alone, but through direct collaboration with academic and industry partners — testing performance across cell types and culture media. This includes a ~50-company consortium building next-gen 3D cell culture tools and a new consortium improving kidney dialysis with living human cells. The partnerships surface real variables, like how much culture media composition affects results, that continually shape product development.

In the biotech industry, advancing cell-based therapies is not just about innovation. It's about solving real gaps where conventional treatments fall short, especially against complex, aggressive tumors.
In this episode of the Smart Biotech Scientist Podcast, host David Brühlmann welcomes Jun Yung Woo, Co-Founder of AGEM Bio, who offers an in-depth look at the science and strategy behind engineered mesenchymal stem cells (MSCs), with a focus on why glioblastoma is the right proving ground for the platform.
Topics discussed:
Why glioblastoma is the right Phase I indication: infiltrative growth, immunosuppression, and STING pathway deficiencies that make GBM uniquely suited to the platform (02:43)
The surgical workflow: intracavity MSC delivery during tumor resection, oral 5-FC administration, and how engineered cells act as local bioreactors in the resection cavity (04:05)
Mechanisms by which engineered MSCs target heterogeneous and invasive tumors through shared vulnerabilities rather than antigen recognition (05:58)
Overcoming immune rejection with allogeneic therapies and the unique immunological profile of MSCs (07:32)
Manufacturing and scale-up: addressing donor variability, GMP production, and building a reproducible process (09:16)
Why GMP manufacturing should be designed in from the earliest stages of research (10:50)
Beyond glioblastoma: expanding the platform to other solid tumors, regenerative medicine, and chronic inflammatory disease (11:27)
Strategies for international trial expansion and partnerships beyond Singapore (12:41)
Reframing MSCs from stem cell therapy to programmable delivery platform: the MSC 2.0 thesis (14:10)
Smart insight: The shift Jun Yung articulates is from treating stem cells as the therapy to treating them as programmable therapeutic vehicles. Once you can reliably engineer, manufacture, and preserve their function, the limitation is no longer what the cell naturally does. It becomes what biology you can encode into it. Glioblastoma is the proving ground, and the platform's reach extends to liver cancers, sarcomas, peritoneal malignancies, and chronic inflammatory disease.
These episodes expand on the same themes of MSC biology, cell engineering, and the challenges of scaling consistent, functional cell therapies:

What if the answer to solid tumor therapy isn’t about making immune cells smarter—but about rethinking what a therapeutic cell can do For years, mesenchymal stem cells (MSCs) have turned heads for their ability to home in on damaged tissue, yet their clinical utility has lagged behind the hype. What would it take to transform MSCs from passive healers into precision vehicles for next-generation cancer treatment?
This week, David Brühlmann sits down with Jun Yung Woo, Co-Founder of AGEM Bio, who’s devoted nearly two decades to decoding and reimagining the potential of MSCs. From engineering stress-resilient cells to pioneering dual-payload therapeutic platforms, Jun Yung Woo bridges fundamental biology and real-world clinical translation.
Topics discussed:
The case for understanding cell biology before focusing on process scale-up in bioprocessing (02:38)
Jun Yung Woo's personal and scientific journey toward developing engineered MSC therapeutics (04:36)
How MSCs sense their environment and exert therapeutic effects via secreted factors, rather than tissue replacement (08:28)
Key differences between MSC therapies and immune cell therapies like CAR T cells (10:35)
Overview of non-viral engineering platforms, and the importance of intracellular trafficking for modifying MSCs (12:23)
Design of AGEM Bio's dual-payload MSC product (cytosine deaminase and interferon beta) to induce highly localized tumor stress and immune activation (14:10)
Strategies for controlling MSC targeting and minimizing off-target effects, including the use of prodrug activation and localized cell delivery (17:23)
Study results from treating companion animals with engineered MSCs, and observations of tumor regression and possible signs of immune memory (20:29)
