Based on fibroblast growth factor 2 (FGF2, bFGF)

  • ability to induce cell proliferation and maintain cells in their undifferentiated state
  • essential component in both stem cell culture and cultured meat media
  • native FGF2 is intrinsically unstable and therefore requires to be added to the media often and in high concentrations


  • Engineered protein with improved stability and longevity
  • Cost-effective as lower concentration is required in the media
  • Patented molecule (WO2017089016A1)
  • Called FGF2-G3 in publications
  • Suitable for cultured meat applications – possibility of reformulation according to the customer’s specs
  • REGULATORY: FGF2-STAB is considered a processing aid with no regulatory requirements limiting its use in cultured meat production
  • Available in both bovine/porcine form, fish forms (salmon, eel and tuna/grouper) and human form
  • Option of supply/collaboration/license agreements


  • Much lower dosage needed (5- to 20-times)
  • Longer half-life (50-times)
  • Fully retained biological activity
  • No need for stabilizing additives
  • Animal-free product


Lower dosage required

Measured by NIH/3T3 fibroblast cell proliferation

* 5-times lower dosage required, but up to 20-times lower dosage required if used in B8 media formulation (Kuo et al., 2020)


50-times longer half-life

Measured by activation of ERK in human ESC CCTL14 culture


Enhanced stability in cell proliferation assay

Tested in BAF3 cells expressing FGFR2c receptor


Temperature stability enhanced by 19°C

Measured by circular dichroism spectroscopy



  • FGF2-STAB® Meat is ready to become a game changer in the cultured meat space as a highly effective and cost-efficient product with global traction
  • FGF2 is a key component of cultured meat media representing around 60% of media cost when wild-type FGF2 is used
  • Scale-up of cultured meat production will require significant reduction of media cost
  • According to the regulatory agencies, growth factors will be considered processing aid in the cultured meat process – therefore no regulatory requirements are limiting the use of our engineered molecule


Possibility of reformulation according to customers’ needs

Open to agreements for supply / collaborations / licenses
