Sand dollar skeleton as templates for bacterial cellulose coating and apatite precipitation
Source abstract
Abstract
In this work, the skeleton of Sand Dollar (Clypeaster subdepressus) was coated by bacterial cellulose (BC) produced by Gluconacetobacter hansenii and subsequently coated with calcium phosphate (apatite). The skeleton of sand dollar is composed of magnesium calcite ((Ca,Mg)CO3) and exhibits an hierarchically porous structure with interconnected porosity. After coating, the small-sized pores were partially covered by cellulose microfibrils, where apatite particles were homogeneously deposited. The pore geometry of sand dollar is adequate for bone regeneration, allows cell migration through its large cells and permit vascularization through the small pores. Moreover, BC/apatite coating offers a bioactive surface for cell adhesion.
