Figure 2. Nanoporous alginate hydrogels rapidly release GM-CSF and TSLP.

Figure 2.

(A) Chemical structure of alginate, m and n subscripts represent the guluronic and mannuronic acid monomers, respectively. (B) AFM height image of a peel-transferred alginate hydrogel layer. Scale bar = 100 nm. (C) Fluorescent image of two intradermally injected alginate hydrogels labeled with PE-Cy7 microbeads overlaying a photograph. (D) Release kinetics of GM-CSF (orange triangles with dashed line) and TSLP (green squares with solid line) in PBS at 37°C. (E) Magnified image of (D). Values in (D) and (E) represent mean and SD (n= 4 for GM-CSF or 7 for TSLP).
