Biomass Microcapsules with Stem Cell Encapsulation for Bone Repair

A novel stem cell delivery core-shell biomass microcapsule was generated by an all-aqueous phase microfluidic electrospray technique. Microcapsule with a certain mechanical strength and porous structure is beneficial for substances exchange between cells and the external environment, together with avoiding cell damage during treatment. Core-shell microcapsule provided a favorable cell growth microenvironment, which mimics a physicochemical microenvironment and protects the cells from the immune attack from body.
