Preparation procedure for tissue engineering, cell culture and cellularized grafts

Preparation procedure for tissue engineering, cell culture and cellularized grafts

Cellularized grafts require a porous structure: here is an example: a 6 mm disc which is sitting in a 96 well plate. This 3D porous matrix is produced from biodegradable polysaccharides. The pore size and overall porosity are controlled.

3D confocal microscopy image reconstruction showing undifferentiated embryonic stem cells ES cultured without an infiltrating feeder layer, in vitro, a 3D biodegradable polysaccharide porous matrix. Dimensions: 1 mm x 1 mm x 200 µm.

 

Small diameter, 2 mm polysaccharide tubes, made of natural polymers with therapeutic vascular properties. The three dimensional matrices are being assessed as vascular replacements.
