Wavelength-biased release of encapsulated cells. a) Macromers containing either B (left of interface) or D (right of interface) were used to encapsulate RFG-expressing hMSCs or GFP-expressing hMSCs. b) The interface between the two gels is directly observable in optical microscopy. c) The rate of release of GFP cells from gel containing linker D is faster than the release of RFP-expressing cells from a gel containing linker B: this is consistent with ratio of the apparent rate constants of degradation (kappD/kappB=2.47; RGFP/RRFP=2.36±0.68).
