기질 자체 히드로 생체 외에서 그리고 Vivo에서 응용 프로그램에 대 한 조립으로 인간의 심장 조직 처리

Executive Industry Relevance

This protocol enables the production of human-derived cardiac extracellular matrix hydrogels and microparticles, providing a tissue-specific microenvironment for studying cell-matrix interactions in cardiac regeneration research. By preserving key biomolecules such as collagen, elastin, and glycosaminoglycans while removing cellular material, the method supports physiologically relevant in vitro and in vivo models. This approach addresses the lack of tissue-specific biological activity in commercial ECM products, offering a scalable source for mechanistic de-risking in cardiac therapeutic development.
