Pyoderma gangrenosum (PG), a rare skin disease of unknown etiology, forms intractable skin ulcers at surgical or traumatic sites. This case is a 40-year-old woman with PG who experienced end-stage renal disease due to type 1 diabetes mellitus. Arteriovenous fistula (AVF) creation and peritoneal dialysis introduction were considered to be difficult, because this patient had a history of developing intractable aseptic ulcers at surgical sites. Therefore, she continued hemodialysis via a temporary catheter. With frequent catheter exchange, there was stenosis of both the femoral veins and the internal jugular vein. Therefore, a hemodialysis catheter that could be used for the long term was inserted into the left jugular vein as a final site. To prevent the patient not being able to continue hemodialysis, we performed a kidney transplantation to save her life. We performed a blood type-compatible, living donor kidney transplantation after confirming the absence of active skin lesions. The 69-year-old donor was her mother. Induction immunotherapy started with tacrolimus, mycophenolate mofetil, steroids, and basiliximab. Intravenous pulses of methylprednisolone were performed to prevent ulceration of the surgical site on days 0-2 (500 mg/d). The postoperative course was excellent. After the operation, ulceration of the surgical site was never observed. The serum creatinine value was 0.87 mg/dL at 6 months. To our knowledge, renal transplantations for a patient with PG has not been previously reported.

Stage-specific embryonic antigen-3 (SSEA-3)-positive multipotent mesenchymal cells (multilineage differentiating stress-enduring [Muse] cells) were isolated from cultured human adipose tissue-derived stem/stromal cells (hASCs) and characterized, and their therapeutic potential for treating diabetic skin ulcers was evaluated. Cultured hASCs were separated using magnetic-activated cell sorting into positive and negative fractions, a SSEA-3+ cell-enriched fraction (Muse-rich) and the remaining fraction (Muse-poor). Muse-rich hASCs showed upregulated and downregulated pluripotency and cell proliferation genes, respectively, compared with Muse-poor hASCs. These cells also released higher amounts of certain growth factors, particularly under hypoxic conditions, compared with Muse-poor cells. Skin ulcers were generated in severe combined immunodeficiency (SCID) mice with type 1 diabetes, which showed delayed wound healing compared with nondiabetic SCID mice. Treatment with Muse-rich cells significantly accelerated wound healing compared with treatment with Muse-poor cells. Transplanted cells were integrated into the regenerated dermis as vascular endothelial cells and other cells. However, they were not detected in the surrounding intact regions. Thus, the selected population of ASCs has greater therapeutic effects to accelerate impaired wound healing associated with type 1 diabetes. These cells can be achieved in large amounts with minimal morbidity and could be a practical tool for a variety of stem cell-depleted or ischemic conditions of various organs and tissues.
