Collagen I:III ratio in canine heterologous bladder acellular matrix grafts.

The objective of this study was to investigate the limitations of a heterologous bladder acellular matrix graft (BAMG) and the influence of the collagen ratio on functional regeneration in a large animal model. Ten female dogs underwent partial cystectomy; eight received BAMG (two homologous; six heterologous) and two partial cystectomy only. A cystometry was performed prior to surgery and 7 months postoperatively when all animals underwent sacral root stimulation.

Homologous acellular matrix graft for vaginal repair in rats: a pilot study for a new reconstructive approach.

The purpose of this paper is to investigate using an acellular matrix graft of vagina (VAMG) or bladder (BAMG) in vaginal reconstruction. In 18 rats, vaginal length was measured and a hysterectomy performed. In three control animals, the vaginal stump was closed.
