Extracellular matrix: The proteins that function throughout the body.

The idea and meetings that planned this issue focused on extracellular matrix (ECM) started over 4 years ago. The invitations were sent to investigators over 2 years ago and manuscripts have been submitted, reviewed, and edited since the summer and fall of 2018. Most of the manuscripts were published in early view in 2019, and we are thrilled to share the final collection. This volume contains 6 reviews, 13 original research papers, and 4 remembrances. Marion (Emmy) Gordon and I organized the articles into seven topic areas, including ECM structure, genetics, and development; cancer; vascular structures and development; inflammation and wound healing; collagen in special structures; cornea and other ocular tissues; and extracellular vesicles.
