Hydrogel patterning with FITC or TAMRA-RGDSC peptides. (a) Hydrogel reactivity depends on alkyne and meth/acrylate concentration in HPGMA. (b) The presence of alkyne groups leads to more efficient incorporation of peptides into HPGMA hydrogels. Combinations of MA and alkyne concentrations (1) – (9) are detailed in Table 2. Scale bar 200 μm.
