How Can We Humanize Pre-Clinical Drug Discovery?

Roughly nine in ten drug candidates fail in the clinic, and species differences are part of the reason why. Human stem cell models offer a way to close that gap, but only if the cells are what they claim to be.

Stem Cells Are Ready for Harder Questions

The next phase of stem cell biology will depend on fit-for-purpose evidence: not simply whether a human cell model can be built, but whether it is the right model for the decision it is meant to support.

Your Cells Passed QC. That May be the Problem.

Standard QC can confirm what cells look like, but not what they are doing. That gap gets expensive downstream.
