Fig. 1From: Effects of dendritic core–shell glycoarchitectures on primary mesenchymal stem cells and osteoblasts obtained from different human donorsSynthetic approach of cationic dendritic core–shell glycoarchitectures PEI-5k-Mal-B and PEI-25k-Mal-B [26, 27]. Due to different sizes of hyperbranched poly(ethylene imine) cores final dendritic core–shell glycoarchitectures provide different hydrodynamic radii (Rh) [26, 27]Back to article page
