Stem cell therapy represents a promising therapeutic avenue for cardiac disorders, including heart failure. Although stem cell transplantation showed encouraging preliminary results, the outcomes of clinical studies are still unsatisfactory. This study aimed to compare the outcomes of two therapeutic approaches, in vivo co-delivery of sodium hydrogen sulfide (NaHS) concomitant with bone marrow-derived mesenchymal stem cell (BMSC) transplantation and in vitro preconditioning of BMSCs with NaHS, both of which are intended to promote the success of stem cell therapy in rats with isoprenaline-induced heart failure...

We studied the effect of mesenchymal stem cells and hemopoietic stem cells co-transplanted in different regimens (sequence and intervals between the injections within 0-48 h) on the rate of the bone marrow hemopoiesis recovery in 468 inbred mice with cytostatic aplasia caused by a single injection of cyclophosphamide in a dose of 500 mg/kg. The efficacy of stem cells was evaluated by animal survival and general physical condition, body weight dynamics, peripheral blood counts (leucocytes, platelets, and reticulocytes), total cellularity and the presence of hemopoietic stem cells in the bone marrow on day 9 after cyclophosphamide injection...

Cell-based tissue engineering is a promising alternative for periodontal regeneration as current therapies fail to reconstitute tissue damage caused by periodontitis. As newly identified postnatal stem cells, gingiva-derived mesenchymal stem cells (GMSCs) have been focused on for isolation and expansion in vitro of cells with multi-differentiation potential and immunomodulatory capacities. It has been demonstrated that systemically delivered GMSCs can home to the mandibular bone defect sites and promote bone regeneration...

Primary central nervous system (CNS) lymphoma is an aggressive brain tumor sensitive to chemotherapy and radiotherapy. Its incidence has increased in the elderly, and they account for the majority of patients. The median survival of patients older than 70 years did not change over the last 40 years and remained in the range of 6-7 months. The definition of elderly is nonuniform, and chronological age is not the best marker of treatment tolerability or a predictor of treatment-related toxicity. Some patients who are fit can tolerate induction, consolidation, and even high-dose chemotherapy with autologous stem cell transplantation, whereas others who have multiple comorbidities with reduced renal and bone marrow function can tolerate only intermediate doses of methotrexate...

Although many recent studies describe the emergence and prevalence of 'clonal-hematopoiesis of indeterminate-potential' (CHIP) in aged human populations, a systematic analysis of the numbers of clones supporting steady-state hematopoiesis throughout mammalian life is lacking. Previous efforts relied on transplantation of 'barcoded' hematopoietic stem cells (HSC) to track the contribution of HSC clones to reconstituted blood. However, ex vivo manipulation and transplantation alter HSC function and thus may not reflect the biology of steady-state hematopoiesis...

Haploidentical stem cell transplantation (haplo SCT) has emerged as an acceptable alternative to matched family donor transplantation for children diagnosed to have primary immune deficiency disorders (PIDs). We present data over 4 years on the challenges and efficacy of unmanipulated T cell replete haplo SCTs with post-transplant cyclophosphamide (PTCy) in children diagnosed to have PIDs. We performed a retrospective study in the pediatric blood and marrow transplantation unit where all children less than 18 years of age diagnosed to have PIDs and who underwent haplo SCT with PTCy from January 2014 to February 2018 were included in the study...

OBJECTIVES: This study aimed to show the positive effects of autologous bone marrow-derived mononuclear cells in the functional recovery of adult patients with subacute and chronic ischemic stroke. Stroke is a leading cause of morbidity and long-term disability in the world, with about one-third of survivors being permanently disabled. Bone marrowderived mononuclear cell concentrate is thought to improve cerebral blood flow and to speed recovery in animal models. Many types of stem cells have been used, including mesenchymal, cord blood cells, and embryonic, with different administration methods, including intrathecal, intravenous, intraarterial, and intracerebral, all with variable degrees of success...

Hemophagocytic lymphohistiocytosis is a rare and life-threatening systemic disease that can cause hepatic infiltration and present as acute liver failure. Here, we report a case of a 3-year-old pediatric patient who presented with acute liver failure and hepatic encephalopathy secondary to hemophagocytic lymphohistiocytosis. She had left lateral segment liver transplant from her father. After 27 months, she had bone marrow transplant from her sister. At the time of reporting (36 months after liver transplant), she showed normal liver function and blood peripheral counts...

Hemophagocytic syndrome combines febrile hepatosplenomegaly, pancytopenia, hypofibrinemia, and hepatic dysfunction. It is characterized by bone marrow and organ infiltration of activated, nonmalignant macrophages that phagocytize blood cells. It is rare among renal transplant recipients. Here, we present the successful management of late-onset cytomegalovirusinduced hemophagocytic lymphohistiocytosis in a kidney transplant recipient after coronary artery bypass graft surgery. In 2012, our patient had end-stage kidney disease due to diabetic nephropathy and underwent related living-donor renal transplant...

Parvovirus B19 is a single-stranded DNA virus that typically has an affinity for erythroid progenitor cells in bone marrow and leads to pure red cell aplasia. This is a common pathogen in humans, and the expression of the infection depends on the host's hematologic and immunologic status. Here, we report a female patient who developed severe and persistent anemia after kidney transplant while being on immunosuppressive therapy. The parvovirus B19 immunoglobulin M test was positive, and the virus was detected by polymerase chain reaction as parvovirus B19 (23...

BACKGROUND: Severe mucopolysaccharidosis type I (also known as Hurler syndrome) is a rare devasting recessive genetic disease caused by the deficiency of an enzyme. Hematopoietic stem cell transplant is the standard of care in the United States, usually conducted before the child is 3 years of age, but little is known about the continued medical and educational needs of the child after transplant. A greater understanding of the burden of illness on the primary caregiver is also needed...

AMD3100 (plerixafor, Mozobil®) was first identified as an anti-HIV agent specifically active against the T4-lymphotropic HIV strains, as it selectively blocked the CXCR4 receptor. Through interference with the interaction of CXCR4 with its natural ligand, SDF-1 (also named CXCL12), it also mobilized the CD34+ stem cells from the bone marrow into the peripheral blood stream. In December 2008, AMD3100 was formally approved by the US FDA for autologous transplantation in patients with Non-Hodgkin's Lymphoma or multiple myeloma...

Stem cells or Cancer stem cells (CSCs) have now been identified in different type of tissues by using surface markers. Functional assays such as ALDEFLUOR and side population which are marker independent have been additional approaches. However, whether all these approaches identify the same population of cells remain uncertain. To address this issue we have used hematopoietic stem cells as a model. Peripheral blood stem cells enumerated by CD34 are used routinely in bone marrow transplantation which supports the recovery of bone marrow after ablative chemotherapy or radiation...

Immune thrombocytopenia (ITP) is a common autoimmune bleeding disorder. The breakdown of immune tolerance (regulatory T [Treg] cells and suppressor cytokines) plays an important role in ITP pathophysiology, especially in refractory ITP. Bone marrow-derived mesenchymal stem cells (BM-MSCs) show immunomodulatory properties and have been extensively utilized for autoimmune diseases. However, it has not been fully elucidated how BM-MSCs affect ITP. In this study, we explore the therapeutic mechanism of BM-MSCs on ITP in mice...

Objectives: Current treatments for osteoporosis were prevention of progression, yet it has been questionable in the stimulation of bone growth. The mesenchymal stem cells (MSCs) treatment for osteoporosis aims to induce differentiation of bone progenitor cells into bone-forming osteoblasts. We investigate whether human umbilical cord blood (hUCB)-MSCs transplantation may induce bone regeneration for osteoporotic rat model induced by ovariectomy. Methods: The ovariectomized (OVX) group (n = 10) and OVX-MSCs group (n = 10) underwent bilateral ovariectomy to induce osteoporosis, while the Sham group (n = 10) underwent sham operation at aged 12 weeks...

Achieving adequate healing in large or load-bearing bone defects is highly challenging even with surgical intervention. The clinical standard of repairing bone defects using autografts or allografts has many drawbacks. A bioactive ceramic scaffold, strontium-hardystonite-gahnite or "Sr-HT-Gahnite" (a multi-component, calcium silicate-based ceramic) is developed, which when 3D-printed combines high strength with outstanding bone regeneration ability. In this study, the performance of purely synthetic, 3D-printed Sr-HT-Gahnite scaffolds is assessed in repairing large and load-bearing bone defects...

Acute myeloid leukemia is a bone marrow malignancy in which blasts count increases by more than 20% in the bone marrow. Allogeneic hematopoietic stem cell transplantation (alloHCT) is a treatment option for these patients with high risk of graft versus host disease (GVHD) development. Chronic GVHD (cGVHD) often mimics a variety of autoimmune conditions such as systemic lupus erythematous or systemic sclerosis. Sclerotic cGVHD has a wide spectrum of oral manifestations, including mucosal atrophy, microstomia, and hyposalivation...
