RATIONALE Bone marrow (BM) cell therapy for ischemic heart disease (IHD) has shown mixed results. Before the full potency of BM cell therapy can be realized, it is essential to understand the BM niche after acute myocardial infarction (AMI). OBJECTIVE To study the BM composition in patients with IHD and severe left ventricular (LV) dysfunction. METHODS AND RESULTS BM from 280 patients with ...
Bone marrow (BM) is the major reservoir for endothelial progenitor cells (EPCs). Postnatal neovascularization depends on not only angiogenesis but also vasculogenesis, which is mediated through mobilization of EPCs from BM and their recruitment to the ischemic sites. Reactive oxygen species (ROS) derived from Nox2-based NADPH oxidase play an important role in postnatal neovascularization; howev...
Bone marrow (BM) derived vascular precursor cells (BM-PC, endothelial progenitors) are involved in normal and malignant angiogenesis, in ischemia and in wound healing. However, the mechanisms by which BM-PC stimulate the pre-existing endothelial cells at sites of vascular remodelling/recovery, and their contribution towards the formation of new blood vessels are still undisclosed. In the presen...
The aim of this study was to explore prognostic factors for non-small cell lung cancer (NSCLC) patients with brain metastases (BM) on the basis of EGFR mutation status. Among 779 consecutive NSCLC patients who underwent EGFR mutation screening, all 197 patients with BM were divided according to the EGFR mutation status. The prognostic factors, including patient characteristics at the time of BM...
Previous studies have demonstrated the association between EGFR mutations and distant metastasis. However, the association for subsequent brain metastasis (BM) in stages I-III non-small cell lung cancer (NSCLC) patients remains inconclusive. We conducted a retrospective analysis to clarify the impact of EGFR mutations on the incidence of BM and associated survival in patients with stage I-III N...
Activated pancreatic stellate cells (PSCs) play a pivotal role in the development of pancreatic fibrosis. The origin of activated PSCs has been thought to be transformation of quiescent PSCs residing locally in the pancreas. Recent studies have suggested that bone marrow (BM)-derived cells participate in regeneration processes in various organs. This study aimed to clarify the contribution of B...
Umbilical cord blood (UCB) is being increasingly used for hematopoietic stem cell transplantation and has been associated with a reduced incidence of severe graft-versus-host disease (GVHD). To further investigate the relative merits of unrelated donor UCB versus bone marrow (BM), a matched-pair analysis comparing the outcomes of recipients of 0 to 3 human leukocyte antigen (HLA)-mismatched UCB...
Purpose The purpose of this study was to determine if there is a quantitative relationship between chronic intracranial pressure (ICP) and peripapillary Bruch's membrane (pp-BM) shape and to determine whether change in pp-BM shape can be detected within 1 hour after ICP lowering by lumbar puncture (LP). Methods In this study, 30° nasal-temporal optical coherence tomography B-scans were obtain...
BACKGROUND AND OBJECTIVES Unlike most other tumors, multiple myeloma (MM) cells have to survive and to grow in a bone marrow (BM) microenvironment which is already hypoxic by nature. BM hypoxia is crucial for normal hematopoiesis. However, how BM hypoxia and MM affect each other is unknown. We addressed this topic in the 5T2MM mouse model. DESIGN AND METHODS Levels of hypoxia in the BM of con...
AIMS/INTRODUCTION Recent studies have shown that cell transplantation therapies, such as endothelial precursor cells, bone marrow-derived mononuclear cells (BM-MNCs) and mesenchymal stem cells, are effective on diabetic polyneuropathy through ameliorating impaired nerve blood flow in diabetic rats. Here, we investigated the effects of BM-MNCs transplantation in diabetic polyneuropathy using BM-...
