Stem cell reagents and small molecule modulators are essential for controlling self-renewal, proliferation and differentiation during stem cell culture in vitro. Researchers working with embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), adult stem cells and cancer stem cells (CSCs) rely on precise pathway modulation to direct cell fate, improve survival and support reproducible culture conditions.
Hello Bio supplies high-quality, affordable stem cell reagents and small molecules targeting key signalling pathways including Wnt, TGF-β/Activin, Notch, Hedgehog and retinoic acid. Our reagents are priced to support academic and grant-funded research — often up to 50% lower than standard suppliers — without compromising quality or performance.

Choosing the Right Stem Cell Reagent
Selection depends on your cell type, workflow stage (maintenance vs differentiation), and whether you’re optimising survival during handling. These quick pointers link to commonly used options:
|
If your priority is cell survival during passaging / cryopreservation |
If you’re working in iPSC reprogramming or Wnt-driven protocols |
|
If you’re supporting neuronal differentiation workflows |
