THE PAST DECADE has been characterized by unprecedented progress in cardiac cell biology and pathophysiology. The dogma of the heart being a terminally differentiated organ has been challenged by compelling evidence generated in several different laboratories around the world (6). These findings were received with a mixture of skepticism and enthusiasm, which has led to an exponential developme...

Stem cell-based cellular therapy is a promising tool for the treatment of pathological conditions with underlying severe tissue damage or malfunction like in chronic cardiovascular, musculoskeletal, inflammatory conditions. One biggest technical challenges use natural stem cells, however, prevention their premature senescence during therapeutical manipulations. Culturing cells under hypoxic bel...

In the 1920s, when the genetic theory of cancer was taking root, German biochemist Otto Warburg (winner of the 1931 Nobel prize in physiology or medicine) proposed that abnormal energy metabolism caused cancer. Cells can generate energy either through oxidative respiration in mitochondria or through glycolysis in the cytoplasm. Warburg showed that tumors have an acidic extracellular environment...

Much of the therapeutic benefit of allogeneic transplant is by a graft versus tumor effect. Further data shows that transplant engraftment is not dependant on myeloablation, instead relying on quantitative competition between donor and host cells. In the clinical setting, engraftment by competition alone is not feasible due to the need for large numbers of infused cells. Instead, low-level host...

Background: With the increase in life expectancy, middle aged and elderly people comprise a substantial percentage of the population worldwide. Since aging often manifests itself in the human skin, skin rejuvenation methods have gained a lot of popularity. Current medical modalities such as botulinum toxininjection, fillers, and laser therapy can provide symptomatic relief of skin aging s...

mesenchymal stem cells (mscs) could differentiate into various types of tissues. these cells serve as a backup for the regeneration and repair of tissues or cells after injury. a skin wound is defined as an injury to the skin that needs to be restored. all types of cells in skin especially mesenchymal stem cells play important role in wound healing process. in particular, paracrine signaling of...

the characteristics of cellular and molecular mechanisms associated with cell proliferation and differentiation is important to understand malignancy. in this report we characterise a leukemic model, d5a1, to study the action of differentiation agent, cellular events and gene expression of the selected transcription factors. cells induced with 4 mm hexamethylene bisacetamide (hmba) caused signs...

lncrnas (long non-coding rnas) are responsible to control the degradation process, rna stability, orchestration, inhibition, transcription and histone modification etc. these rnas have been termed as the key agents of several mechanisms such as development, organogenesis and regeneration of damaged tissues etc. they interact with a number of partner molecules either protein, rnas or dnas and co...

Background: Common resistant-to-therapy warts pose a challenge to both clinicians and patients. Among many destructive and immunotherapeutic options, no single, fully effective treatment has been suggested yet. Many investigations, including those using intralesional antigen administrations, have demonstrated that cellular immunity plays a major role in the clearance of human papilloma virus (H...
