Effects of fibrin pad hemostat on the wound healing process in vivo and in vitro.

Fibrin Pad is a hemostatic pad designed to control surgical-related bleeding. It consists of a fully absorbable composite matrix scaffold coated with human-derived active biologics that immediately form a fibrin clot upon contact with targeted bleeding surfaces. Studies were conducted to investigate the effect of Fibrin Pad and its biologics-free composite matrix component (Matrix) on the wound healing process in in vitro and in vivo models.

Regulation of outside-in signaling in platelets by integrin-associated protein kinase C beta.

Studies with inhibitors have implicated protein kinase C (PKC) in the adhesive functions of integrin alpha(IIb)beta(3) in platelets, but the responsible PKC isoforms and mechanisms are unknown. Alpha(IIb)beta(3) interacts directly with tyrosine kinases c-Src and Syk. Therefore, we asked whether alpha(IIb)beta(3) might also interact with PKC.

Protein-protein interactions in platelet alphaIIbbeta3 signaling.

The major platelet integrin alpha (IIb)beta (3) is the main receptor involved in platelet functions such as aggregation and spreading on extracellular matrix. Like all other integrins, alpha (IIb)beta (3) is capable of transducing signals both from inside and outside of the cell. To mediate these functions, alpha (IIb)beta (3) interacts with intracellular and transmembrane proteins.
