Understanding the Extracellular Matrix to Enhance Stem Cell-Based Tissue Regeneration

Laura E Niklason. Cell Stem Cell. .

Abstract

The extracellular matrix is a biologically critical entity that has historically been poorly understood. Here we discuss how new tools for characterizing matrix composition and function enable us to design and deliver advanced matrices in vitro, to optimize regeneration, and in vivo, within a variety of tissues and organs.

(A) Acellular matrix from adult rat lung shows alveolar barrier integrity, with retention of yellow micro-particles that are injected into the airway. (B) Mixed neonatal rat pulmonary epithelium that is seeded onto an acellular lung scaffold organizes to form airway structures containing cells expressing clara cell secretary protein (green) as well as keratin5, a basal cell marker (red).
