Renal tissue reconstitution by the implantation of renal segments on biodegradable polymer scaffolds.
Renal units were created in vivo by transplanting isolated renal segments on three-dimensional, biodegradable polymer scaffolds. Renal segments, freshly isolated from rat kidneys, were seeded on polymer scaffolds and subcutaneously implanted in athymic mice for two and four weeks. Three-dimensional renal reconstructs were formed with glomeruli and tubules, showing a possibility of reconstituting renal structures by transplanting renal segments.
