• To identify novel recipes that enhance reprogramming efficiency and quality.
• To understand the underlying mechanisms of iPSC generation.

Main Methods:

• Utilized a systems biology framework to analyze reprogramming pathways.
• Evaluated a large set of potential reprogramming recipes.
• Estimated cell-state landscapes and identified transition states.

Main Results:

• Recovered several known, experimentally validated reprogramming recipes.
• Proposed novel recipes predicted to improve iPSC generation.
• The approach facilitates monitoring reprogramming progress and identifying key regulatory states.

Conclusions:

• The systems biology approach efficiently identifies effective iPSC reprogramming recipes.
• This method can accelerate the development of safer and more efficient cell therapies.
• Understanding cell-state dynamics is key to optimizing iPSC generation.
