Human adipose tissue-derived mesenchymal stem cells for treatment of refractory pure red cell aplasia after major ABO-incompatible hematopoietic stem cell transplantation / 中国组织工程研究

ABSTRACT

The present study retrospectively analyzed 2 patients suffering from refractory pure red cell aplasia after major ABO-incompatible hematopoietic stem cell transplantation who received treatment in the Henan Institute of Haematology between April 2004 and February 2006. Patient 1 was a 25-year-old female with acute lymphocytic leukemia in second remission, and patient 2 was a 16-year-old gid with acute myeloid leukaemia in second remission. The two patients received a transplant of human adipose tissue-dedved mesenchymal stem cells (1.0×106/kg). Both of them acquired rapid recovery from pure red cell aplasia without any side effects. These findings suggest that adipose tissue-dedved mesenchymal stem cells seem to be a promising therapeutic option in patients with refractory pure red cell aplasia after ABO-incompatible hematopoietic stem cell transplantation, in whom conventional treatment fails.
