Cell adhesion behavior in 3D hydrogel scaffolds functionalized with D- or L-aminoacids.

Alginate hydrogels functionalized with D-, or L-penicillamine (D-, L-PEN-Alg) are used as new 3D scaffolds for cell adhesion studies. The cells recognize and show different adhesion properties in the respective 3D hydrogel scaffolds. C-6-glioma and endothelial cells show higher affinity to the D-PEN than to the L-PEN functionalized 3D alginate hydrogel scaffold. The cultivated cells are harvested from the hydrogel and are reused, for example, for cell growth experiments on 2D surfaces to prove their viability as well.
