I N recent years a number of methods have been developed to induce donor-specific transplantation tolerance in adult recipients using bone marrow transplantation. 1-4 One approach. using a mixture of syngeneic and allogeneic bone marrow to prepare allogeneic chimeras (A + B A) has been demonstrated to be effective in achieving longterm donor-specific transplantation tolerance to alloantigens in...

Bone marrow microenvironment is fundamental for hematopoietic homeostasis. Numerous efforts have been made to reproduce or manipulate its activity to facilitate engraftment after hematopoietic stem cell transplantation but clinical results remain unconvincing. This probably reflects the complexity of the hematopoietic niche. Recent data have demonstrated the fundamental role of stromal and myel...

Recovery of bone marrow cellularity, CFU-C, and CFU-S were studied sequentially over 90 days time after syngeneic bone marrow transplantation in mice. A minimal cell dose of 2 X 10(5) bone marrow cells was given. At day 28 after transplantation, CFU-C reached more than 50% of the normal range whereas the CFU-S concentration was less than 15%. Normalization of CFU-S occurred at day 90. The effec...

We described the successful allogeneic matched sibling bone marrow transplantation (BMT) in a 5-year-old Thai boy in whom osteopetrosis was diagnosed on the basis of anemia, thrombocytopenia, leukoerythroblastosis, sclerotic bone, hepatosplenomegaly, and visual deficit from an encroachment of cranial nerve foramina. The preparative regimen included 4 days of busulfan 4 mg/kg/day, and 4 days of ...

Myelodysplastic syndrome (MDS) is a set of clonal bone marrow diseases in children that are characterised by peripheral cytopenia, dysplastic alterations the marrow, and inefficient hematopoiesis. MDS uncommon children, with just 1-4 occurrences per million afflicted. Adults, particularly elderly, more susceptible to disease. Some hereditary disorders, such as Fanconi's anaemia, Shwachman's, Do...

Medical tourism emerged when people were challenged with high costs and slow service in medical care. As a consequence of these issues, people started to look for medical treatment in other countries. Globalization accelerated the growth of medical tourism. Several “push” and “pull” factors play roles in the motivation of patients to become a medical tourist. This review addresses the different...

BACKGROUND.: To test the angiogenesis-promoting effects of bone marrow cells when cotransplanted with islets. METHODS.: Streptozotocin-induced diabetic BALB/c mice were transplanted syngeneically under the kidney capsule: (1) 200 islets, (2) 1 to 5x10 bone marrow cells, or (3) 200 islets and 1 to 5x10 bone marrow cells. All mice were evaluated for blood glucose, serum insulin, and glucose toler...

Abstract A promising strategy to increase the numbers of hematopoietic stem cells (HSCs) for clinical applications, like cell transplantation, is offered by advanced in vitro culture systems. We developed artificial 3D bone marrow-like scaffolds made polydimethylsiloxane (PDMS) mimicking natural HSC niche . These PDMS combination with an optimized medium allow amplification high undifferentiate...

BACKGROUND Despite current interest in the biology and diagnostic applications of cell-free DNA in plasma and serum, the cellular origin of this DNA is poorly understood. We used a sex-mismatched bone marrow transplantation model to study the relative contribution of hematopoietic and nonhematopoietic cells to circulating DNA. METHODS We studied 22 sex-mismatched bone marrow transplantation p...
