Key result
TGF-β signaling drives transient Collagen XII deposition during zebrafish heart regeneration.
Why the study?
The contribution and regulation of specific collagen types during zebrafish heart regeneration remain poorly characterized.

Does TGF-β receptor inhibition with SB431542 affect Collagen XII expression during zebrafish heart regeneration?
TGF-β signaling coordinates the formation of a transient collagenous network involving Collagen I and XII in the reparative matrix of regenerating zebrafish hearts.
Marro et al. (2016) studied Zebrafish heart regeneration. SB431542 (TGF-β receptor inhibitor) vs. 0.1% DMSO was evaluated. Collagen XII is transiently upregulated in the epicardium and fibrotic tissue during zebrafish heart regeneration, and its deposition in the injury zone is dependent on TGF-β signaling.
