Bone marrow architecture is grossly distorted at the diagnosis of ALL and details of the morphological changes that accompany response to Induction chemotherapy have not been reported before. While marrow aspirates are widely used to assess initial response to ALL therapy and provide some indications, we have enumerated marrow components using morphometric analysis of trephine samples with the ...

BACKGROUND Bisphosphonates have been widely used for treatment of high bone resorption states. It lowers bone turnover by inhibiting osteoclasts bone resorption with various mechanisms of actions: inhibition of osteoclast formation and attachment to the bone surface, induction of metabolic injury, alteration of vesicle trafficking and induction of osteoclast apoptosis. Bone biopsies studies fro...

When decalcified lyophilised bone matrix (Urist, Silverman, Biiring, Dubuc and Rosenberg 1967) is implanted intramuscularly in other animals of the same species, new cartilage, bone and bone marrow appear. The sequence of events leading to this induction and its main features were described in detail by Urist and his co-workers (Urist and Dowell 1968; Urist, Dowell, Hay and Strates 1968: Thomps...

Background: Cell therapy of many neurodegenerative diseases using bone marrow stromal cells (BMSC) requires the differentiation of BMSC into neuronal subtype. However, the transdifferentiation of BMSC into GABAergic phenotype requires more investigation. Methods: In this study, BMSC of adult female rats were pre-induced into neuroblast-like cells using 1 mM β-mercaptoethanol (βME) and 10 M re...

PURPOSE To determine whether granulocyte colony-stimulating factor (G-CSF) administered during acute myelogenous leukemia (AML) induction affects hematopoietic and nonhematopoietic toxicity, length and outcome of induction therapy, event-free survival, overall survival, and prognostic significance of the day 7 bone marrow. PATIENTS AND METHODS In Children's Cancer Group study 2891, patients w...
