BACKGROUND AIMS: Primary hematopoietic stem and progenitor cells (HSPCs) are key components of cell-based therapies for blood disorders and are thus the authentic substrate for related research. We propose that ubiquitous small-volume diagnostic samples represent a readily available and as yet untapped resource of primary patient-derived cells for cell- and gene-therapy studies. METHODS: In the present study we compare isolation and storage methods for HSPCs from normal and thalassemic small-volume blood samples, considering genotype, density-gradient versus lysis-based cell isolation and cryostorage media with different serum contents...

BACKGROUND: Parturition at term and preterm is characterized by sterile inflammatory processes occurring in the absence of infection whereby peripheral leukocytes infiltrate gestational tissues in response to chemotactic signals. In response to a homing signal, recruited leukocytes undergo diapedesis and extravasate through capillaries, migrating into stromal tissue. There they interact with resident immune and stromal cells to produce a mixture of matrix metalloproteinases, prostaglandins and cytokines including interleukin-1β (IL-1β) and IL-6 that in turn transform the uterus from pregnancy to parturition...

ETHNOPHARMACOLOGICAL RELEVANCE: Aqueous bark extract of Terminalia arjuna (TA) has been in use as an ethnomedicine for cardiovascular ailments in the Indian subcontinent for centuries. Studies using hemodynamic, ROS scavenging and anti-inflammatory parameters in animal models have shown its anti-atherogenic, hypotensive, inotropic, anti-inflammatory effects. However, details analysis on its effects on established molecular and cell biological markers are a prerequisite for its wider acceptance to the medical community...

Chitosan (CS) has received great attention in tissue engineering, especially in wound healing acceleration. In this study, chitin was isolated from desert locust (Schistocerca gregaria) and shrimp (Penaeus monodon) then deacetylated to chitosan. Then, chitosan was characterized by degree of deacetylation (DD), molecular weight (M.Wt), swelling index (SI), Fourier transform infrared (FTIR) and X ray diffraction (XRD). The chitosan was then casted into 2D scaffolds and was pictured using scanning electron microscope (SEM)...

Human induced pluripotent stem cells (hiPSCs) are being considered for use in understanding haematopoietic disorders and as a potential source of in vitro manufactured red cells. Here, we show that hiPSCs are able to recapitulate various stages of developmental erythropoiesis. We show that primitive erythroblasts arise first, express CD31(+) with CD235a(+) , embryonic globins and red cell markers, but fail to express the hallmark red cell transcripts of adult erythropoiesis. When hiPSC-derived CD45(+) CD235a(-) haematopoietic progenitors are isolated on day 12 and further differentiated on OP9 stroma, they selectively express CD36(+) and CD235a(+) , adult erythroid transcripts for transcription factors (e...

Adults who were affected by intrauterine growth restriction (IUGR) suffer from reductions in muscle mass and insulin resistance, suggesting muscle growth may be restricted by molecular events that occur during fetal development. To explore the basis of restricted fetal muscle growth, we used a sheep model of progressive placental insufficiency-induced IUGR to assess myoblast proliferation within intact skeletal muscle in vivo and isolated myoblasts stimulated with insulin in vitro. Gastrocnemius and soleus muscle weights were reduced by 25% in IUGR fetuses compared to controls (CON)...

An epidemic of Zika virus (ZIKV) infection associated with congenital abnormalities such as microcephaly, is ongoing in the Americas and the Pacific. Currently there are no approved therapies to treat this emerging viral disease. Here, we tested three cell-directed broad-spectrum antiviral compounds against ZIKV replication using human retinal pigment epithelial (RPE) cells and a low-passage ZIKV strain isolated from fetal brain. We found that obatoclax, SaliPhe, and gemcitabine inhibited ZIKV infections at noncytotoxic concentrations...

The liver has a marked capacity for regeneration. In most cases the liver regeneration is determined by hepatocytes. The regenerative capacity of hepatocytes is significantly reduced in acute or chronic damage. In particular, repair mechanisms are not activated in patients with alcoholic cirrhosis. Organ transplantation or advanced methods of regenerative medicine can help such patients. The promising results were obtained in clinical trials involving patients with various forms of liver disease who received transplantation of autologous bone marrow stem cells...

Lytic growth of intracellular Toxoplasma gondii tachyzoite stages over a period of days results in plaques within mononolayers of host cells. Plaque assays are in frequent use to isolate single clones and to investigate invasion, replication and egress over a longer time frame. To allow correlating plaque morphology and/or size with ultrastructural examination of individual parasites we introduce a simple protocol for correlative light and electron microscopy (CLEM) of entire plaques. We also illustrate the advantages of visualizing only the boundaries of plaques by staining for infected cells ('positive staining') rather than the traditional staining of the intact cell monolayer, thus outlining the area of lysed cells ('negative staining')...

BACKGROUND: Recent findings suggest that adult terminally differentiated cardiomyocytes adapt to stress by cellular de- and redifferentiation. In the present study we tested the hypothesis that swiprosin-1 is a key player in this process. Furthermore, the relationship between swiprosin-1 and β-adrenoceptor coupling was analyzed. METHODS: In order to study the function of swiprosin-1 in adult rat ventricular cardiomyocytes (ARVC) they were isolated and cultured in a medium containing 20% fetal calf serum (FCS)...

BACKGROUND: The human body has an extensive capacity to regenerate bone tissue after trauma. However large defects such as long bone fractures of the lower limbs cannot be restored without intervention and often lead to nonunion. Therefore, the aim of the present study was to assess the pool and biological functions of human mesenchymal stromal cells (hMSCs) isolated from different bone marrow locations of the lower limbs and to identify novel strategies to prime the cells prior to their use in bone fracture healing...

Human umbilical cord matrix (hUCM) is considered as a promising source of mesenchymal stem cells (MSCs) due to several advantages over other tissues. The potential of neural differentiation of hUCM-MSCs is of great interest in the context of treating neurodegenerative diseases. In recent years, considerable efforts have been made to establish in vitro conditions for improving the differentiation of hUCM-MSCs toward neuronal cells. In the present study, we evaluated the neural differentiation potential of hUCM-MSCs in the presence of cAMP-elevating agents forskolin and 3-isobutyl-1-methylxanthine (IBMX)...

Down syndrome (DS) is a birth defect with huge medical and social costs, caused by trisomy of whole or part of chromosome 21. It is the most prevalent genetic disease worldwide and the common genetic cause of intellectual disabilities appearing in about 1 in 400-1500 newborns. Although the syndrome had been described thousands of years before, it was named after John Langdon Down who described its clinical description in 1866. Scientists have identified candidate genes that are involved in the formation of specific DS features...

Porcine islets have notoriously low insulin secretion levels in response to glucose stimulation. While this is somehowexpected in the case of immature islets isolated from fetal and neonatal pigs, disappointingly low secretory responses are frequently reported in studies using <em>in vitro</em>-maturated fetal and neonatal islets and even fully-differentiated adult islets. Herein, we show that beta-cell specific expression of a modified glucagon-like peptide 1 (GLP-1) and of a constitutively activated type 3 muscarinic receptor (M3R) efficiently amplifies glucose-stimulated insulin secretion (GSIS)...
