Implication

Randomized trial shows thermal stability of FGF regulates self-renewal and differentiation in human pluripotent stem cells, indicating critical protein characteristics.

Key Points

This research aims to evaluate how the thermal stability of fibroblast growth factor (FGF) affects self-renewal and differentiation in human pluripotent stem cells.
Evaluated different FGF family members for their ability to maintain human embryonic stem cells in an undifferentiated state.
Assessed ERK phosphorylation and NANOG expression under standard culture conditions.
Compared wild-type FGF1 with a thermal-stable FGF1 variant.
FGF2, FGF4, FGF6, and FGF9 successfully sustained ERK phosphorylation and NANOG expression in human ESCs.
Wild-type FGF1 failed to maintain ERK phosphorylation and NANOG expression due to thermal instability.
A mutated thermal-stable FGF1 effectively supported both differentiation and reprogramming protocols in human ESCs.
