摘要

EBs can be acellularized by detergent extraction methods to yield novel biomaterials. Fluorescent intensity readings suggest a significant decrease in cellular and cytoskeletal content while histological and fluorescent imaging suggests that ECM material remains. Acellularized EBs are also being analyzed by immunohistochemistry and RT-PCR to identify specific extracellular matrix components produced by the cells. Histological analysis using matrix-specific stains is also being performed to evaluate the presence of collagen, elastin, and glycosaminoglycans in both untreated and acellularized EBs. After optimization of the acellularization protocol, future work will include in vivo experiments to assess the- efficacy of the acellularized EBs as a novel biomaterial to facilitate tissue repair.
