Figure 1From: Biocompatibility and resorption pattern of newly developed hyaluronic acid hydrogel reinforced three-layer poly (lactide-co-glycolide) membrane: histologic observation in rabbit calvarial defect modelScheme of three-layer PLGA membrane. First, centrifugation was performed to incorporate hyaluronic acid gel in a porous PLGA membrane. And hyaluronic acid hydrogel layers were attached on both sides of hylauronic acid incorporated PLGA membrane.Back to article page
