Myocardial infarction (MI) is one of the most frequent causes death in industrialized countries. Stem cells therapy seems to be very promising for regenerative medicine. Skeletal myoblasts transplantation into postinfarction scar has been shown effective failing heart but shows limitations such, e.g. cell retention and survival. We synthesized investigated superparamagnetic iron oxide nanoparticles (SPIONs) as an agent direct labeling, which can used stem imaging. High quality, monodisperse...

Duchenne muscular dystrophy (DMD) is a genetic disorder associated with progressive deficiency of dystrophin that leads to skeletal muscle degeneration. In this study, we tested the hypothesis co-transplantation two stem/progenitor cell populations, namely bone marrow-derived mesenchymal stem cells (BM-MSCs) and muscle-derived (SM-SPCs), directly into dystrophic can improve function DMD patients. Three patients diagnosed DMD, confirmed by gene mutation, were enrolled study approved local...

Background: Modern therapies of post infarcted heart failure are focused on perfusion improvement the injured myocardium. This effect can be achieved by, among other means, implanting stem cells which could genetically modified with factors inducing formation new blood vessels in infarction scar area. Combined cell and gene therapy seems to a promising strategy heal an impaired The creation indirectly stimulated via vascular endothelial growth factor synthesis, for example nitric oxide...

We analyzed three cases of Complete Androgen Insensitivity Syndrome (CAIS) and report hitherto undisclosed causes the disease. RNA-Seq, Real-timePCR, Western immunoblotting, immunohistochemistry were performed with aim characterizing disease-causing variants. In case No.1, we have identified a novel androgen receptor (AR) mutation (c.840delT) within first exon in N-terminal transactivation domain. This thymine deletion resulted frameshift thus introduced premature stop codon at amino acid...

Cardiovascular diseases are a growing problem in developing countries; therefore, there is an ongoing intensive search for new approaches to treat these disorders. Currently, cellular therapies focused on healing the damaged heart by implanting stem cells modified with pro-angiogenic factors. This approach ensures that introduced capable of fulfilling complex requirements environment, including replacement post-infarction scar able contract and promote formation blood vessels can supply...

Cardiovascular diseases along with MI (myocardial infarction) lead to regional ischaemia and hypoxic conditions, which prevail after infarction. Diminished O2 saturation is related elevated level of hypoxia inducible factor 1 (HIF-1) transcription factor, may switch the expression many genes. To maximize effect therapies proposed by regenerative medicine, it essential verify (within different time points MI) proangiogenic genes their receptors that are regulated, HIF-1α.
