In order to induce an efficient bone formation with human bone marrow mesenchymal stromal cells (hBMSC) associated to a scaffold, it is crucial to determine the key points of the hBMSC action after in vivo transplantation as well as the appropriate features of a scaffold. To this aim we compared the hBMSC behavior when grafted onto two biomaterials allowing different bone potential in vivo. The cancellous devitalized Tutoplast®-processed bone (TPB) and the synthetic hydroxyapatite/β-tricalcium-phosphate (HA/βTCP) which give at 6 weeks 100% and 50% of bone formation respectively...

Breast cancer is one of the most common cancers in women in the world. Although breast cancer is well treatable at the early stage, patients with distant metastases show a poor prognosis. Data from recent studies using transplantation models indicate that Mint3/APBA3 might promote breast cancer malignancy. However, whether Mint3 indeed contributes to tumor development, progression, or metastasis in vivo remains unclear. To address this, here we examined whether Mint3 depletion affects tumor malignancy in MMTV-PyMT breast cancer model mice...

BACKGROUND: Bone Marrow Transplantation(BMT) is used to treat children with various hematologic, oncologic and metabolic diseases. While the treatment is lifesaving, it is also found to be related with anxiety, posttraumatic stress disorder, depression and psychosocial problems both in children and parents. METHODS: The aim of this study was to investigate psychopathology in pediatric BMT survivors and their mothers compared to the healthy controls. All children were interviewed using Kiddie Schedule for Affective Disorders and Schizophrenia for assessing the life-long psychopathology...

Although BMT is lifesaving in many childhood diseases, it was found to be related to anxiety, depression, and PTSD in parents, and PTSD, anxiety and overall low self-esteem in siblings. Research on siblings' HRQoL is limited. The aim of this study was to investigate PTSD and HRQoL in siblings (donor and non-donor) of pediatric BMT survivors and PTSD in their mothers, compared to the healthy controls. Thirty-five siblings and their mothers and 35 healthy peers and their mothers were recruited as the study group and as the comparison group, respectively...

Coexistence of different hereditary diseases is a known phenomenon in populations with a high consanguinity rate. The resulting clinical phenotypes are extremely challenging for physicians involved in the care of these patients. Here we describe a 6-year-old boy with co-occurrence of a homozygous splice defect in OSTM1, causing infantile malignant osteopetrosis, and a loss-of-function variant in MANEAL, which has not been associated with human disease so far. The child suffered from severe infantile-onset neurodegeneration that could not be stopped by bone marrow transplantation...

Muscle satellite cells are essential for muscle regeneration. However, efficient regeneration does not occur without muscle-resident mesenchymal progenitor cells. We show here that bone marrow-derived mesenchymal stromal cells (Bm-MSCs) also facilitate muscle regeneration in Duchenne muscular dystrophy (DMD) model mice. Bm-MSCs transplanted into peritoneal cavities of DMD model mice with severe muscle degeneration strongly suppressed dystrophic pathology and improved death-related symptoms, which resulted in dramatic lifespan extension...

Mesenchymal stromal cells (MSCs) have shown to be a promising tool in cell therapies to treat different conditions. Several pre-clinical and clinical studies have proved that the transplantation of MSCs improves wound healing. Here, we compare the beneficial effects of mouse bone marrow-derived allogeneic MSCs (allo-mBM-MSCs) and their acelullar derivatives (allo-acd-mMSCs) on skin wound healing in Non-Obese Diabetic (NOD) mice. One dose of allo-mBM-MSCs (1×106 cells) or one dose of allo-acd-mMSCs (1X) were intradermally injected around wounds in 8-10 week old female NOD mice...

CBL is a tumor suppressor gene on chromosome 11 encoding a multivalent adaptor protein with E3 ubiquitin ligase activity. Germline CBL mutations are dominant. Pathogenic de novo mutations result in a phenotype that overlaps Noonan syndrome (1). Some patients with CBL mutations go on to develop juvenile myelomonocytic leukemia (JMML), an aggressive malignancy that usually necessitates bone marrow transplantation. Using whole exome sequencing methods, we identified a known mutation in CBL in a 4-year-old Caucasian boy with atypical hemolytic uremic syndrome, moyamoya phenomenon, and dysmorphology consistent with a mild Noonan-like phenotype...

Tumor protein 53 mutations adversely affect the prognosis of myelodysplastic syndromes (MDS); however, few studies have reported on the prognostic significance of the expression of p53 protein in MDS. The current study investigated p53 immunoreactivity (p53-IR) in bone marrow biopsies (BMBs) obtained at diagnosis from 18 patients (6 females and 12 males; mean age, 50.5 years) with MDS that underwent bone marrow transplantation (BMT) to determine the associations between clinical and histopathological data and outcome...

Polyvinylpyrrolidone-iodine (PVP-I) is a broad-spectrum antimicrobial agent, but its effects on tendon-bone healing are unclear. The purpose of this study was to investigate the effects of PVP-I on bone marrow mesenchymal stem cells (BMSCs) in vitro and on tendon-bone healing in vivo. In this study, following investigation of the concentration-dependent effects of PVP-I on the viability and osteogenic differentiation of BMSCs, the appropriate concentration of PVP-I was selected for animal experiments. New Zealand white rabbits received autologous tendon transplantation with and without PVP-I treatment of the graft tendon...

This review aims to describe the current status of benign bone marrow (BM) imaging using PET. BM imaging is important as the BM is not only involved in poiesis of different vital cell lines and can be affected by primary BM disorders, but it is also frequently affected by several extramedullary diseases. Indications for the use of PET in benign BM disorders are the detection of extramedullary hematopoiesis, evaluation of patients with a discrepancy between BM histology and clinical status, visualizing BM infarctions, location of the optimal site for BM biopsy, diagnosing and staging of other hematological BM disorders, evaluation of radiotherapy effect on BM, and evaluation of BM transplantation...

We designed a novel haploidentical hematopoietic stem cell transplantation (haplo-HSCT) system using idarubicin (IDA) intensified conditioning regimens and combination of antithymocyte globulin and basiliximab for GvHD prophylaxis. The outcomes of 110 high-risk acute leukemia patients undergoing haplo-HSCT were compared with 69 contemporaneous high-risk patients receiving HLA-matched sibling transplantation using uniform IDA-intensified regimens. The relapse incidence of haplo-HSCT was 23.4%, and 3-year overall survival (OS) and disease-free survival (DFS) achieved 62...

Hematopoietic bone marrow stem cell transplantation has been regularly used in clinical practice for over 40 years. Further research indicates that bone marrow stromal cells are also stem cells that are capable of self-renewal, proliferation and differentiation. With appropriate induction, the bone marrow stromal cells can differentiate into bone, cartilage, tendon, adipose tissue and fibrous tissue, which would potentially be applied for treating bone loss diseases. This review outlines research in understanding role of bone marrow stem cells and stem cells from other origins in bone repair, and highlight the current and potential stem cell based treatment for bone loss diseases in the future...

Hematopoietic stem cells play the vital role of maintaining appropriate levels of cells in blood. Therefore, regulation of their fate is essential for their effective therapeutic use. Here we report the role of polyunsaturated fatty acids (PUFAs) in regulating hematopoiesis which has not been explored well so far. Mice were fed daily for 10 days with n-6/n-3 PUFAs, viz. linoleic acid (LA), arachidonic acid (AA), alpha-linolenic acid and docosahexanoic acid (DHA) in four separate test groups with phosphate-buffered saline fed mice as control set...

Despite the successes of bone marrow mesenchymal stem cell (BMSC) transplantation for the treatment of spinal cord injuries, only a small fraction of grafted cells migrate to the target areas. Therefore, there remains a need for more efficient strategies of BMSC delivery. The present study was designed to explore this. Rat models of spinal cord injury (SCI) were established and exposed to phosphate buffered saline (control), BMSCs or BMSCs + erythropoietin (EPO). Basso, Beattie and Bresnahan (BBB) locomotor scale and grid walk tests were then utilized to estimate neurological rehabilitation...

BACKGROUND: We previously reported that mesenchymal stem cells (MSCs) possess therapeutic effects in a murine model of carbon tetrachloride-induced acute liver failure. In the study, we observed that the majority of repopulated hepatocytes were of recipient origin and were adjacent to transplanted MSCs; only a low percentage of repopulated hepatocytes were from transplanted MSCs. The findings indicate that MSCs guided the formation of new hepatocytes. Exosomes are important messengers for paracrine signaling delivery...

Allogeneic stem cell transplantation (SCT) from an HLA-matched sibling donor (MSD) is a postremission treatment that offers a potential cure for adults with cytogenetically normal (CN) acute myelogenous leukemia (AML) in first complete remission (CR1). The best alternative in the absence of an MSD remains unclear, however. The aim of this study was to retrospectively compare the outcomes of autologous peripheral blood stem cell transplantation (auto-PBSCT; n = 177) and allogeneic bone marrow transplantation (BMT) from an HLA-matched unrelated donor (MUD; n = 173) in adult patients with CN-AML/CR1...

Transplantation of bone marrow derived stem cells (BMSCs) has been reported inhibits liver fibrosis. Several in vitro studies by co-culturing BMSCs and hepatic stellate cells (HSCs) indirectly or directly in 2D models showed inhibition of HSC as the key player in liver fibrosis. In this study, we investigated direct effect of BMSCs on HSCs by co-culturing BMSCs and HSCs in 3D model as it represents the liver microenvironment with intricate cell-cell and cell-matrix interactions. Primary isolated rat HSCs and BMSCs were directly co-cultured at 1:1 ratio with hanging drop method...

Recent studies implicate the Cyr61, CTGF, Nov (CCN) matricellular signaling protein family as emerging players in vascular biology, with NOV (alias CCN3) as an important regulator of vascular homeostasis. Herein, we examined the role of CCN3 in the pathogenesis of atherosclerosis. In response to a 15-week high-fat diet feeding, CCN3-deficient mice on the atherosclerosis-prone Apoe(-/-) background developed increased aortic lipid-rich plaques compared to control Apoe(-/-) mice, a result that was observed in the absence of alterations in plasma lipid content...
