Abstract
We investigated bone marrow (BM) recovery of hematopoietic stem cells (HSC) and hematopoietic microenvironment after chemotherapy in childhood acute lymphoblastic leukemia (ALL). Twenty-nine de novo childhood ALL patients were enrolled and BM biopsy sections at diagnosis (BM0), after induction (BM1), consolidation (BM3), interim maintenance (BM5) and delayed intensification (BM7) chemotherapy were obtained. Expressions of CD133, CD34, CD117, osteopontin, osteonectin, CXCL12, and CXCR4 were evaluated by semiquantitative immunohistochemical stains. All markers recovered significantly following chemotherapy while highest values at BM3 (for CD133/CD117/CXCL12/CXCR4), BM5 (for CXCL12/CD34/osteonectin), and BM7 (for osteopontin). Patients with cytogenetic good risk expressed significantly more CD133+/CD34+ cells than those with standard and poor risk in BM5. Patients without aberrant immunophenotype expressed significantly more CD133+ cells in BM1, and more CD117+ cells in BM5 than those with aberrant immunophenotype. Patients treated with standard risk-average chemotherapeutic protocol expressed significantly more CXCR4+ cells than those treated with other protocols in BM7. Patients who showed lowest ANC ≥ 200/µL during induction chemotherapy expressed significantly more CXCR4+ cells at from BM1 to BM5, and more CD133+ cells in BM3 than those who did not. Early and full recovery of BM HSC is most vigorous at BM3 and BM5, respectively. Reconstruction of BM niche and stromal cell recovery is mostly active at BM5, and hematopoietic activity of BM niche recovers mostly at BM7. Patients with cytogenetic good risk, nonaberrant immunophenotype, standard risk-average chemotherapeutic protocol and less BM suppression during induction chemotherapy show prompt recovery of some BM HSC and microenvironment markers compared to others.

Abstract
Breast microcalcification is a potential diagnostic indicator for non-palpable breast cancers. Microcalcification type I (calcium oxalate) is restricted to benign tissue, whereas type II (calcium hydroxyapatite) occurs both in benign as well as in malignant lesions. Microcalcification is a pathological complication of the mammary gland. Over the past few decades, much attention has been paid to exploit this property, which forms the basis for advances in diagnostic procedures and imaging techniques. The mechanism of its formation is still poorly understood. Hence, in this paper, we have attempted to address the molecular mechanism of microcalcification in breast cancer. The central theme of this communication is "how a subpopulation of heterogeneous breast tumor cells attains an osteoblast-like phenotype, and what activities drive the process of pathophysiological microcalcification, especially at the invasive or infiltrating front of breast tumors". The role of bone morphogenetic proteins (BMPs) and tumor associated macrophages (TAMs) along with epithelial to mesenchymal transition (EMT) in manipulating this pathological process has been highlighted. Therefore, this review offers a novel insight into the mechanism underlying the development of microcalcification in breast carcinomas.

Abstract
Objective The aim of this paper was to evaluate the repair of onlay autogenous bone grafts covered or not covered by an expanded polytetrafluoroethylene (e-PTFE) membrane using immunohistochemistry in rats with induced estrogen deficiency. Material and Methods Eighty female rats were randomly divided into two groups: ovariectomized (OVX) and with a simulation of the surgical procedure (SHAM). Each of these groups was again divided into groups with either placement of an autogenous bone graft alone (BG) or an autogenous bone graft associated with an e-PTFE membrane (BGM). Animals were euthanized on days 0, 7, 21, 45, and 60. The specimens were subjected to immunohistochemistry for bone sialoprotein (BSP), osteonectin (ONC), and osteocalcin (OCC). Results All groups (OVX+BG, OVX+BMG, SHAM+BG, and SHAM+BMG) showed greater bone formation, observed between 7 and 21 days, when BSP and ONC staining were more intense. At the 45-day, the bone graft showed direct bonding to the recipient bed in all specimens. The ONC and OCC showed more expressed in granulation tissue, in the membrane groups, independently of estrogen deficiency. Conclusions The expression of bone forming markers was not negatively influenced by estrogen deficiency. However, the markers could be influenced by the presence of the e-PTFE membrane.

Abstract
Mammographic mammary microcalcifications are routinely used for the early detection of breast cancer, however the mechanisms by which they form remain unclear. Two species of mammary microcalcifications have been identified; calcium oxalate and hydroxyapatite. Calcium oxalate is mostly associated with benign lesions of the breast, whereas hydroxyapatite is associated with both benign and malignant tumors. The way in which hydroxyapatite forms within mammary tissue remains largely unexplored, however lessons can be learned from the process of physiological mineralization. Normal physiological mineralization by osteoblasts results in hydroxyapatite deposition in bone. This review brings together existing knowledge from the field of physiological mineralization and juxtaposes it with our current understanding of the genesis of mammary microcalcifications. As an increasing number of breast cancers are being detected in their non-palpable stage through mammographic microcalcifications, it is important that future studies investigate the underlying mechanisms of their formation in order to fully understand the significance of this unique early marker of breast cancer.

Abstract
C3H10T1/2/Osx, a stably transfected cell line with Osterix (Osx), was produced and chondrocytic and osteoblastic differentiation were studied in vitro. Osx promoted osteoblastic lineage that was dexamethasone dependent. Furthermore, in vivo, Osx induced ectopic mineralization in a heterotopic mouse muscle model. Skeletogenesis involves a cascade of molecular activities sequentially performed by osteoblasts and chondroblasts. A transcriptional factor gene Osx appears to influence cell disposition toward the chondrocytic or osteoblastic phenotype and therefore may be an important signaling cue for bone formation. Understanding the molecular conditions involved with Osx promoted osteoblast differentiation will facilitate therapeutic applications of Osx. Consequently, the objective of this study was to investigate chondrocytic and osteoblastic phenotype differentiation using an Osx plasmid DNA exploiting both in vitro and in vivo methodologies. In vitro, a stably transfected C3H10T1/2/Osx cell line was established and promotion of either an osteoblast or chondroblast phenotype was performed by selectively introducing dexamethasone (dex) and assaying mRNA content and phenotype markers. In vivo, a mouse muscle model was used to determine heterotopic ossification using designated Osx plasmid DNA doses incorporated in a (50:50 Poly (D,L-lactide-co-glycolide) (i.e., PLGA) 3D scaffold. Histological assessment was used to determine implant responses. Quantitative real-time polymerase chain reaction (q-RT-PCR) showed a significant increase in mRNA expression of osteocalcin (Ocn), Runx2, osteonectin (On) and osteopontin (Op) (p < 0.05) in the C3H10T1/2/Osx cells compared to the empty vector transfected cell control. At day 21, mineralization was demonstrated in the cultures of C3H10T1/2/Osx exposed to dex, but neither in cultures lacking dex nor controls. In the absence of dex, C3H10T1/2/Osx cells revealed a significantly higher expression of Sox9 and Aggrecan (Agc). In vivo, 80 microg of Osx plasmid DNA induced heterotopic mineralization 4 weeks following implantation in a mouse muscle model and the effect was dependent on the Osx plasmid DNA dose delivered in the PLGA scaffold. Using a non-committed cell line (C3H10T1/2), cell differentiation to an osteoblast phenotype appears to be dependent upon an interaction between intracellular events initiated by the transcriptional factor Osx and the presence of dex. The in vivo findings suggest Osx may promote osteoblast differentiationand mineralization at a heterotopic site.

Abstract
We examined proliferation of cells associated with PTH-induced peritrabecular bone marrow fibrosis in rats as well as the fate of those cells after withdrawal of PTH. Time-course studies established that severe fibrosis was present 7 d after initiation of a continuous sc PTH infusion (40 microg/kg.d). To ascertain cell proliferation, rats were coinfused for 1 wk with PTH (treated) or vehicle (control) and [3H]thymidine (1.5 mCi/rat). Groups of control and treated rats were killed immediately (d 0) and 1 wk (d 7) later. Few osteoblasts (Obs) and osteocytes in treated and control groups were radiolabeled on d 0. Peritrabecular cells expressing a fibroblastic (Fb) phenotype and surrounded by an extracellular matrix were not present in controls on either d 0 or d 7. Multiple cell layers of Fbs lined most (70%) of the bone surface on d 0 in treated rats and nearly all (85%) of the Fbs were radiolabeled. Fbs had entirely disappeared from bone surfaces on d 7. Eighty-five percent of the Obs on and 73% of the osteocytes within the active remodeling sites were radiolabeled. Immunohistochemistry revealed that Fbs induced by PTH treatment produced osteocalcin, osteonectin, and core binding factor-alpha1. These data provide compelling evidence that Fbs recruited to bone surfaces in response to a continuous PTH infusion undergo extensive proliferation, express osteoblast-specific proteins, and produce an extracellular matrix that is similar to osteoid. After restoration of normal PTH levels, Fbs differentiated to Obs, providing further evidence that Fbs are preosteoblasts.

Abstract
Osteonectin is a matricellular protein involved in various cellular mechanisms but its exact function remains unclear despite numerous studies. We present here the cloning of Sparus aurata partial osteonectin cDNA and the reconstruction of 15 other sequences from both vertebrates and invertebrates, almost doubling the set of available sequences (a total of 35 sequences is now available). Taking advantage of the resulting large amount of data, we have created multiple sequence alignments and identified osteonectin putative conserved features (intra- and inter-disulfide bonds, collagen- and calcium-binding domains and phosphorylation sites) likely to be important for protein structure and function. This work also provides the first evidence for the presence of more than one osteonectin in some species. Finally, S. aurata osteonectin gene expression has been shown to initiate during larval development shortly after gastrulation, and to be high in bone-derived cell lines while down-regulated during extracellular matrix mineralization, further emphasizing the important role of osteonectin in skeletal development and bone formation.

Abstract
The in situ localization of osteoblast/osteocyte factor 45 (OF45) mRNA during bone formation has been examined in the rat mandible from embryonic day 14 (E14) up to postnatal 90-day-old Wistar rats. Gene expression was also examined during cell culture not only in primary rat osteoblast-like cells but also in two clonal rat osteoblastic cell lines with different stages of differentiation, ROB-C26 (C26) and ROB-C20 (C20) using Northern blot analysis. The C26 cell is a potential osteoblast precursor cell line, whereas the C20 cell is a more differentiated osteoblastic cell line. At E15 osteoblast precursor cells differentiated into a group of osteoblasts, some of which expressed the majority of non-collagenous proteins, whereas no expression of OF45 was observed in these cells. Intercellular matrices surrounded by osteoblasts were mineralized at E16. Subsequently, the number of osteoblasts differentiated from osteoblast precursor cells was increased in association with bone formation. At E17, the first expression of OF45 mRNA was observed only in a minority of mature osteoblasts attached to the bone matrix, but not in the rest of less mature osteoblasts. At E20, concomitant with the appearance of osteocytes, OF45 mRNA expression was observed not only in more differentiated osteoblasts that were encapsulated partly by bone matrix but also in osteocytes. Subsequently, osteocytes increased progressively in number and sustained OF45 mRNA expression in up to 90-day-old rats. Northern blot analysis of the cultured cells with or without dexamethasone treatment revealed that the gene expression of OF45 correlated well with the increased cell differentiation. These results indicate that OF45 mRNA is transiently expressed by mature osteoblasts and subsequently expressed by osteocytes throughout ossification in the skeleton and this protein represents an important marker of the osteocyte phenotype and most likely participates in regulating osteocyte function.
