Abstract (original English)
Fragmin/protamine microparticles (F/P MPs) have been used as a cell carrier for adipose-derived stromal cells (IR-ASCs) in inbred male Fisher 344 rats, and for preservation and controlled-release of fibroblast growth factor (FGF)-2 and various cytokines in inbred rat plasma (IRP)-DMEM (Dulbecco's modified Eagle's medium) gel. In this study, we investigated the capability of an IRP-DMEM gel containing F/P MPs and/or FGF-2, as a three-dimensional (3D)-culture, to expand IR-ASCs. We found that IR-ASCs grow faster under 3D-culture conditions in low IRP (3%)-DMEM gel containing F/P MPs and FGF-2 without any animal serum than those under 2D-culture in low inbred rat serum (3%)-DMEM with F/P MPs and FGF-2. About 0.3 mL of IR-ASCs (about 4,000,000 cells mL⁻¹) grown in IRP (6%)-DMEM gel containing F/P MPs and FGF-2 disappeared 8 days after subcutaneous injection in rats, suggesting that they are rapidly biodegradable. The number of large (diameter ≥200 μm or containing ≥100 erythrocytes), medium (diameter = 20-200 μm or containing 10-100 erythrocytes) and small (diameter ≤20 μm or containing 1-10 erythrocytes) capillaries after injection with IR-ASCs in an IRP-DMEM gel containing both F/P MPs and FGF-2, as well as the thickness of tissue granulation per microphotograph at the injected site, was significantly higher than those after injection with IR-ASCs in an IRP-DMEM gel containing ei
