A Polymerized cylindrical SGE hydrogels SGE 2–0-0 (SF 2%), SGE 2–2-0 (SF 2%, GTA 2%), SGE 2–1.5–0.5 (SF 2%, GTA 1.5%, hpcECM 0.5%), SGE 2–1-1 (SF2%, GTA 1%, hpcECM 1%). with changes in transparency according to composition. B Surface structure analysis by scanning electron microscopic imaging of SGE composite hydrogels chemically crosslinked by HRP/H2O2 and incubated in PBS up to 28 days. Arrows in SGE-2–1-1 group show hpcECM deposition by forming fibers across the pores. (Scale bars 50 µm)
