Two Methods for Decellularization of Plant Tissues for Tissue Engineering Applications Michal Adamski1, Gianluca Fontana2, Joshua R. Gershlak4, Glenn R. Gaudette4, Hau D. Le1, William L. Murphy2,3 1Department of Surgery, University of Wisconsin-Madison, 2Department of Orthopedics and Rehabilitation, University of Wisconsin School of Medicine and Public Health, 3Department of Biomedical Engineering, University of Wisconsin College of Engineering, 4Department of Biomedical Engineering, Worcester Polytechnic Institute Here we present, and contrast two protocols used to decellularize plant tissues: a detergent-based approach and a detergent-free approach. Both methods leave behind the extracellular matrix of the plant tissues used, which can then be utilized as scaffolds for tissue engineering applications.

Biofunctionalized Plants As Diverse Biomaterials for Human Cell Culture Advanced Healthcare Materials. | Pubmed ID: 28319334 The commercial success of tissue engineering products requires efficacy, cost effectiveness, and the possibility of scaleup. Advances in tissue engineering require increased sophistication in the design of biomaterials, often challenging the current manufacturing techniques. Interestingly, several of the properties that are desirable for biomaterial design are embodied in the structure and function of plants. This study demonstrates that decellularized plant tissues can be used as adaptable scaffolds for culture of human cells. With simple biofunctionalization technique, it is possible to enable adhesion of human cells on a diverse set of plant tissues. The elevated hydrophilicity and excellent water transport abilities of plant tissues allow cell expansion over prolonged periods of culture. Moreover, cells are able to conform to the microstructure of the plant frameworks, resulting in cell alignment and pattern registration. In conclusion, the current study shows that it is feasible to use plant tissues as an alternative feedstock of scaffolds for mammalian cells.
