A Biologically Inspired Material For Stem-Cell Induced Cartilage Renvironmental Protection Agencyir

This award by the Biomaterials program in the Division of Materials Research to New Jersey Institute of Technology will investigate a novel, semi-synthetic derivative of cellulose, which is one of the most abundant natural materials, for use as a tissue engineering scaffold for cartilage rEnvironmental Protection Agencyir. Articular cartilage has a limited capacity to heal. Specialized constructs incorporating cells as well as materials that more closely mimic the structure of the cartilage extracellular matrix during early development may be a promising strategy for promoting the formation of functional cartilage tissue. Sodium cellulose sulfate is water soluble and mimics the structure of glycosaminoglycans. It is a linear polysaccharide that can be synthesized with varying degrees of sulfation for improved bioactivity. Sodium cellulose sulfate could impart functional qualities that are similar to glycosaminoglycans, direct chondrogenesis and cartilage tissue formation. Sodium cellulose sulfate will be combined with gelatin in a fibrous form to more closely mimic the natural extracellular matrix of cartilage in both structure and function. The first aim of the project will be the fabrication and characterization of sodium cellulose sulfate -gelatin fibrous scaffolds with the goal of determining construct(s) that best support cell growth and infiltration. Aim 2 will determine sodium cellulose sulfate constructs that promote mesenchymal stem cell-induced cartilage formation and integration with surrounding host cartilage in vitro. The goals of this project are to develop a novel combination therapy for the rEnvironmental Protection Agencyir of cartilage defects and enhance the scientific understanding of the role of biologically inspired materials and their effect on cell differentiation. The research efforts here will also be disseminated in teaching, training, and education. Of particular interest is the inclusion of underrepresented minorities and women in the scope of its impact. The principal investigator's laboratory is actively involved in the recruitment, training and mentorship of underrepresented minority and female students starting at the junior high school level through various community and university programs.


This project will develop a biologically inspired material for cartilage tissue rEnvironmental Protection Agencyir. Joint rEnvironmental Protection Agencyir continues to be a significant challenge that demands the use of innovative materials that can provide biological function. Specialized constructs incorporating cells as well as materials that more closely mimic the structure of cartilage tissue during early development may be a promising strategy for promoting the formation of functional cartilage tissue. Sodium cellulose sulfate mimics the structure of glycosaminoglycans present in cartilage tissue and can be prEnvironmental Protection Agencyred with varying degrees of functional groups to improve its biological performance. Sodium cellulose sulfate containing materials will be evaluated with stem cells for the formation of cartilage tissue. The goals of this project are to develop a novel combination therapy for the rEnvironmental Protection Agencyir of cartilage defects and enhance the scientific understanding of the role of biologically inspired materials and their effect on cell function.
