Abstract (original English)
Recently, adipose tissue has been regenerated by combining scaffolds, growth factors, and/or adipose-tissue-derived stromal cells. However, the safety of growth factors and adipose-tissue-derived stromal cells has not been confirmed in cancer patients. We reported the regeneration of adipose tissue in the internal space of a polypropylene mesh containing a collagen sponge (CS), without using any growth factors or cells. We herein explored the formation of adipose tissue, using the bioabsorbable implant containing CS, in rats. We prepared the implants without and with CS, using threads of either poly-l-lactide-co-ε-caprolactone or poly-l-lactic acid (PLLA), and measured their strengths. The procedure was performed in the rat inguinal region. In the control group, no operative procedure was performed. In the sham-operation group, skin incision without implantation was performed. The other groups received CS alone and the 2 implants with and without CS. The areas of formed tissue and adipose tissue inside the implants and the remnants of CS were evaluated. All implants maintained the internal space before implantation. At 6 and 12 months after implantation, the internal space was maintained and the formation of adipose tissue was promoted in the 2 PLLA groups. At 6 months, the internal space was maintained, and more adipose tissue was formed in the PLLA-with-CS group than in the P
