General description

Each unit contains 100mg of material.

Application

The extracellular matrix (ECM), comprised of proteins and other growth factors, plays a pivotal role in directing and mediating cellular activities in a tissue or an organ. Decellularized extracellular matrix (dECM) could not only replicate natural ECM microenvironment, but also provide tissue specific compositions and topology. dECM bioink is capable of providing optimized tissue-specific microenvironment conducive to the growth of 3D structured tissues. Decellularized ECM bioink precursor is provided as an aseptic form. Reconstitution protocol is provided to prepare dECM bioink solution. The final bioink is used for bioprinting self-supporting 3D structures.
