Figure 1From: Adrenomedullin delivery in microsphere-scaffold composite for remodeling of the alveolar bone following tooth extraction: an experimental study in the ratSchematic illustrations of TPP-chitosan microspheres preparation (a) and microsphere-scaffold composite fabrication (b). The chitosan microspheres loaded with ADM were prepared by the emulsion method in the presence of TPP, carrying five negative charges which allows the electrostatic interaction with positively charged amino group of chitosan in an aqueous acidic solution.Back to article page
