TLDR
To regenerate functional tissue, rat kidney scaffolds are seeded with epithelial and endothelial cells and perfused these cell-seeded constructs in a whole-organ bioreactor, resulting in grafts that produced rudimentary urine in vitro when perfused through their intrinsic vascular bed.Abstract:
Approximately 100,000 individuals in the United States currently await kidney transplantation, and 400,000 individuals live with end-stage kidney disease requiring hemodialysis. The creation of a transplantable graft to permanently replace kidney function would address donor organ shortage and the morbidity associated with immunosuppression. Such a bioengineered graft must have the kidney's architecture and function and permit perfusion, filtration, secretion, absorption and drainage of urine. We decellularized rat, porcine and human kidneys by detergent perfusion, yielding acellular scaffolds with vascular, cortical and medullary architecture, a collecting system and ureters. To regenerate functional tissue, we seeded rat kidney scaffolds with epithelial and endothelial cells and perfused these cell-seeded constructs in a whole-organ bioreactor. The resulting grafts produced rudimentary urine in vitro when perfused through their intrinsic vascular bed. When transplanted in an orthotopic position in rat, the grafts were perfused by the recipient's circulation and produced urine through the ureteral conduit in vivo.read more

Direct comparison of different coating matrix on the hepatic differentiation from adipose-derived stem cells
Xuan Zhang,Jiahong Dong +1 more
TL;DR: It is demonstrated that liver DCM as coating matrix could significantly enhance the hepatic differentiation from ADSCs compared with collagen, fibronectin and Matrigel both in the presence and absence of GFs, and indicated that DCM could promote the differentiation of ADSCs into hepatocyte-like cells, which demonstrates feasibility of liverDCM as a bio-scaffold for liver regenerative medicine and tissue engineering.

Tissue Engineered Scaffolds for an Effective Healing and Regeneration: Reviewing Orthotopic Studies
TL;DR: The present paper aims to review the results of in vivo tissue engineering experimentations, focusing on the role of the scaffold and its specificity with respect to the tissue to be regenerated, in order to verify whether an extracellular matrix-like device, as usually stated, could promote an expected positive outcome.

TL;DR: Five patients with end-stage renal disease received combined bone marrow and kidney transplants from HLA single-haplotype mismatched living related donors, with the use of a nonmyeloablative preparative regimen, and it was possible to discontinue all immunosuppressive therapy 9 to 14 months after the transplantation.
