Bone marrow-derived cells (BMCs) are considered to be a major source of mesenchymal stem cells (MSCs) in adults and are known to be effective in periodontal tissue regeneration. However, whether endogenous BMCs are involved in periodontal tissue repair process is uncertain. We therefore created periodontal tissue defects in the buccal alveolar bone of mandibular first molars in bone marrow chim...

Fucoidan is a sulfated polysaccharide purified from brown algae including Fucus vesiculosus and has a variety of biological effects including mobilization of hematopoietic progenitor cells. Recently, we demonstrated that fucoidan stimulates the antigen-presenting functions of dendritic cells. In this study, we investigated the radioprotective effects of fucoidan on bone marrow cells (BMCs), whi...

Systemic instigation is a process by which endocrine signals sent from certain tumors (instigators) stimulate BM cells (BMCs), which are mobilized into the circulation and subsequently foster the growth of otherwise indolent carcinoma cells (responders) residing at distant anatomical sites. The identity of the BMCs and their specific contribution or contributions to responder tumor growth have ...

The objective of this study was to classify the different routes of the bifid mandibular canals (BMCs) on 2400 panoramic radiographs in a Syrian population. BMCs were identified, drawn and classified according to the classification of Langlais et al. BMCs were found in 41 cases (0.98%). A total of 15 canals (36.6%) were classified as Class I, 6 canals (14.6%) as Class II, 8 canals as Class III ...

OBJECTIVE Humoral immunity has been clearly implicated in solid organ transplantation, but little is known about the relationship between humoral immunity and hematopoietic stem cell transplantation. This study was designed to investigate that relationship. MATERIALS AND METHODS Sensitized serum was obtained from a sensitized murine model established by allogeneic splenocyte transfusion. Sens...

Bacterial microcompartments (BMCs) are self-assembling organelles that sequester segments of biochemical pathways within a protein shell. Given their functional diversity, BMCs constitute a rich source of metabolic modules for applications in synthetic biology. The carboxysome, the cyanobacterial BMC for CO(2) fixation, has attracted significant attention as a target for installation into chlor...

BACKGROUND Pre-clinical studies have shown that hypoxia preconditioning can enhance stem cell therapeutic potential for myocardial repair. We sought to investigate the safety and feasibility of intracoronary administration of hypoxia-preconditioned bone marrow mononuclear cells (HP-BMCs) for acute ST segment elevation myocardial infarction (STEMI). METHODS We randomized 22 patients with acute...

Bone marrow transplantation (BMT) is a powerful strategy for the treatment of leukemia, aplastic anemia, congenital immunodeficiency and autoimmune diseases. In humans, bone marrow cells (BMCs) have usually been collected by multiple bone marrow aspirations from the iliac crest. We have established a new “perfusion” method for collecting BMCs with minimal contamination with the peripheral blood...

The recently discovered capacity of bone marrow cells (BMCs) to contribute to injury-induced skeletal muscle regeneration has brought new possibilities in the treatment of skeletal muscle diseases. However, a suitable method of BMC transplantation usable for such therapy has to be established. In this work, recipient mice were intramus...

BACKGROUND Intracoronary transfer of autologous bone marrow cells (BMCs) promotes recovery of left ventricular systolic function in patients with acute myocardial infarction. Although the mechanisms of this effect remain to be established, homing of BMCs into the infarcted myocardium is probably a critical early event. METHODS AND RESULTS We determined BMC biodistribution after therapeutic ap...
