Key result
Periostin regulates functional tendon healing by forming a matrix niche supporting myofibroblast differentiation and persistence.
Why the study?
Disrupting persistent myofibroblast activity is a key therapeutic target to prevent fibrotic scar tissue during tendon healing, but directly disrupting alphaSMA is translationally untenable due to expression in other cell types.
The Periostin matrix niche is a critical regulator of myofibroblast fate and persistence during tendon healing, representing a potential therapeutic target for regenerative healing.

Hypothesis-generating for periostin-targeted tendon regeneration; leaves open translation to human clinical outcomes.
Ackerman et al. (2023) studied Tendon injuries and fibrosis. Periostin matrix niche was evaluated on Myofibroblast differentiation and persistence during tendon healing. Periostin forms a supportive matrix niche that facilitates myofibroblast differentiation and persistence, identifying it as a critical regulator of functional tendon healing.
