Summary Hepatosplenic γ/δ T-cell lymphoma (HSTL) is a very rare, aggressive extranodal affecting mainly young adults. Clinically, presents with symptomatic hepatosplenomegaly and systemic symptoms but without lymphadenopathy. The diagnosis confirmed after careful evaluation of bone marrow liver biopsies or, in some cases, diagnostic splenectomy. Overall, survival short regardless chemotherapy r...

Background: Acute myeloid leukemia (AML) is characterized by the proliferation of myeloid precursors and abnormal differentiation of hematopoietic stem cells, which results in the accumulation of immature cells in the bone marrow (BM). The accumulation of these cells in the bone marrow causes molecular and cellular changes in the microenvironment of the bone marrow. The adiponectin hormone orig...

We hypothesized that a chemically extracted acellular allogeneic nerve graft used in combination with bone marrow mesenchymal stem cell transplantation would be an effective treatment for long-segment sciatic nerve defects. To test this, we established rabbit models of 30 mm sciatic nerve defects, and treated them using either an autograft or a chemically decellularized allogeneic nerve graft w...

Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...

stem cells are of great interest for regenerating disturbed tissues and organs. these cells are commonly isolated from the bone marrow, but there has been interest in other tissues in the recent years. in this study, we evaluated the possibility of isolation of stem cells from oral connective tissue and investigated their characteristics.in this experimental study, sampling from the bone marrow...

Increase in endothelial cell sloughing and diminished function of endothelial stem cell progenitors in diabetic subjects are well known phenomena. We hypothesized that transplantation of bone marrow stem cells (BMSCs) including mesenchymal stem cells but not limited to CD34(+) stem cells into type 2 diabetic ob mice would restore insulin sensitivity and glucose tolerance. This approach, when co...

Primary bone marrow diffuse large B-cell lymphoma (DLBCL) is a rare type of extranodal lymphoma with poor prognosis. Here, we report a case of primary bone marrow DLBCL successfully treated with high-dose chemotherapy and rescued by in vivo rituximab-purged autologous stem cells. A 39-year-old woman visited our hospital because of anemia. Bone marrow examination revealed a large B-cell lymphoma...

BACKGROUND & AIMS Liver transplantation is the primary treatment for various end-stage hepatic diseases but is hindered by the lack of donor organs and by complications associated with rejection and immunosuppression. There is increasing evidence to suggest the bone marrow is a transplantable source of hepatic progenitors. We previously reported that multipotent bone marrow-derived mesenchymal ...

the introduction and evolution of hematopoietic stem cell transplantation (hsct) could be traced back to 1950s, to the studies on interactions among irradiation, covering spleen and bone marrow from it and injection of bone marrow cells. today, hsct is considered a well-established, effective and promising means of therapy for various malignant and non-malignant medical conditions, both in chil...

To investigate the supplement of lost nerve cells in rats with traumatic brain injury by intravenous administration of allogenic bone marrow mesenchymal stem cells, this study established a Wistar rat model of traumatic brain injury by weight drop impact acceleration method and administered 3 × 10(6) rat bone marrow mesenchymal stem cells via the lateral tail vein. At 14 days after cell transpl...
