Tolerance-based stem cell transplantation using sublethal conditioning is being considered for the treatment of human disease, but safety and efficacy remain to be established. We have shown that mouse bone marrow recipients treated with sublethal irradiation plus transient blockade of the CD40-CD154 costimulatory pathway develop permanent hematopoietic chimerism across allogeneic barriers. We ...

BACKGROUND The standard treatment for decompensated liver cirrhosis is liver transplantation. However, it has several limitations. Recent animal studies suggest that bone marrow stem cell transplantation can lead to regression of liver fibrosis. The objective of this study was to determine the safety and feasibility of autologous bone marrow-mesenchymal stem cell transplantation in patients wit...

introduction: it is an unfamiliar, frightening and stressful experience for the parents of a child who is undergoing bone marrow transplantation. it is impossible to propose an effective caring method without considering all dimensions related to such experience. objective: the purpose of this study was to describe and understand the lived experiences of parents whose children were undergoing b...

The prospect of cell-based therapy for kidney disease remains controversial despite its immense promise. We had previously shown that transplanting bone marrow and hematopoietic stem cells could generate renal cells and lead to the preservation of kidney function in a mouse model for cystinosis (Ctns(-/-)) that develops chronic kidney injury, 4 months post transplantation. Here, we determined t...

objective(s):immunosuppressive property of mesenchymal stem cells (mscs) has great attraction in regenerative medicine especially when dealing with tissue damage involving immune reactions. the most attractive tissue sources of human mscs used in clinical applications are bone marrow (bm), adipose tissue (at), and wharton's jelly (wj) of human umbilical cord. the current study has compared...

BACKGROUND Malignant infantile osteopetrosis (MIOP) presents early in life with extreme sclerosis of the skeleton and reduction of bone marrow spaces. Since there is a defect in the bone marrow, the disease can cause anemia, extramedullary hematopoiesis secondary to anemia leading to hepatosplenomegaly, cranial nerves compression and severe growth failure. This disorder is often lethal within t...
