Figure 3From: Rheological and biological properties of a hydrogel support for cells intended for intervertebral disc repair Injection and harvest of cell-loaded hydrogels. A: Injection from dual syringe and 1.3 mm Ø needle. The hydrogel (arrow) polymerizes upon injection and forms a stable subcutaneous protrusion. B: Hydrogel (arrow) at harvest. Note the absence of vascular and connective tissue ingrowth.Back to article page
