Key result
CTHRC1-expressing cardiac fibroblasts emerge post-MI and localize to the scar to prevent ventricular rupture.
Why the study?
Due to a limited set of bona fide markers, characterization of cardiac fibroblast heterogeneity in response to cardiac injury was lacking.
CTHRC1 identifies a unique subpopulation of cardiac fibroblasts crucial for the healing scar process after myocardial infarction, preventing ventricular rupture.

CTHRC1+ fibroblasts merit exploration as rupture-prevention targets post-MI; hypothesis-generating pending human validation.
Ruiz‐Villalba et al. (2020) studied Myocardial Infarction. CTHRC1-expressing cardiac fibroblasts emerge after myocardial infarction, localize to the scar, and are crucial for preventing ventricular rupture.
