text: The fibro-vascular reticulated structure, made up of an open network of random lattices of small cross-sections coupled with very high porosity (79-93%), having very low density (0.02-0.04 g/cm(3) ), and high specific pore volume (21-29 cm(3) /g), has the characteristics of a carrier/scaffold well-suited for cell immobilization.
