Area of Science:

• Biotechnology
• Cell Biology
• Biophysics

Background:

• Realizing stem cell potential necessitates efficient bioprocesses.
• Mechanobiological principles are crucial for optimizing stem cell behavior.

Purpose of the Study:

• Emphasize mechanotransduction in stem cell bioprocesses.
• Explore mechanisms of sensing mechanical cues and transcriptional responses.
• Identify and address sources of noise and cell-to-cell variability.

Main Methods:

• Propose a conceptual framework for mechanical force impact.
• Identify key cell state determinants in bioprocesses.
• Discuss downstream implementation challenges.

Main Results:

• Mechanotransduction is a governing principle in stem cell bioprocesses.
