Corroboration of computational models for mechanoregulated stem cell differentiation

Area of Science:

• Mechanobiology
• Computational Biology
• Tissue Engineering

Background:

• Computational models are increasingly used in mechanobiology.
• The 'paradox of validation' suggests that validating mechanoregulation theories may negate their necessity.
• This paradox arises when validation data renders the initial theoretical model obsolete.

Purpose of the Study:

• To review the corroboration of theories describing the mechanoregulation of tissue differentiation.
• To assess the predictive power of computational models in mechanobiology.
• To investigate the impact of the 'paradox of validation' on mechanobiology research.

Main Methods:

• Review of existing literature on mechanobiology theories and computational models.
• Analysis of the falsifiability of computational models as a measure of predictive power.
• Examination of theories related to mechanoregulation of tissue differentiation.

Main Results:

• Some theories in mechanobiology exhibit poor predictive power, leading their models into the 'paradox of validation'.
• Theories designed to minimize falsifiability contribute to this paradox.
• Several theories demonstrate predictive power beyond their initial validation data.

Conclusions:

• Mechanobiology requires theories with greater potential for falsifying experiments to advance.
• The 'paradox of validation' highlights a potential limitation in current mechanobiology theories.
• As the field matures, the 'paradox of validation' is expected to diminish with stronger, more predictive theories.
