To date, no viable therapeutic options exist for the effective and sustained reversal of cardiac failure, other than heart transplantation and mechanical circulatory assist devices. Therefore, divergent strategies aiming at the de novo formation of contractile tissue, as a prerequisite for the restoration of cardiac pump function, are currently being pursued. Clinical trials involving the transplantation of somatic progenitor cells failed. The search for alternative cell-based strategies to combat the consequences of ischemic injury has sparked widespread interest in the genetic and pharmacologic reprogramming of fibroblasts into cardiomyocytes, harnessing the abundant in vivo pool of cardiac fibroblasts. Here, we provide a comprehensive overview of in vitro and in vivo cardiac reprogramming studies identified in an extensive literature search. We systematically review and evaluate feasibility, efficiency, and reproducibility of the different technologies currently being explored. Finally, we discuss potential safety issues deduced from preclinical studies and identify obstacles that must be overcome before clinical translation.-Klose, K., Gossen, M., Stamm, C.

Cardiac fibrosis is a common pathologic consequence of stress insult to the heart and is characterized by abnormal deposition of fibrotic extracellular matrix that compromises cardiac function. Cardia...
The purpose of this study is to investigate the change in chemotactic effects of human conjunctival fibroblasts (HConFs) after transdifferentiation into myofibroblasts, and to explore related molecula...
TGFβ superfamily includes the transforming growth factor βs (TGFβs), bone morphogenetic proteins (BMPs), growth and differentiation factors (GDFs) and Activin/Inhibin families of ligands. Among the...
Thymosin beta-4 (Tβ4) is an actin sequestering protein and is furthermore involved in diverse biological processes including cell proliferation, differentiation, wound healing, stem- or progenitor ce...
Bioengineering cardiac tissue constructs with adult cardiomyocytes may help treat adult heart defects and injury. In this study, we fabricated cardiac tissue constructs by seeding adult rat cardiomyoc...
Fibroblasts can be cultured from human skin biopsies using fetal bovine serum and artificial growth medium. Fibroblasts cultured in this way retain the genetic characteristics of their do...
Evaluation of the difference in pressure ulcer incidence or the time to develop pressure ulcers depending on the turning frequencies.
Intensive care unit (ICU) patients on respirators are at high risk for preventable pulmonary complications (PPC). Turning these patients from side to side may reduce PPC, but carries the b...
The purpose of this study is to test whether optimal patient turning, strictly every 2 hours with at least 15 minutes of tissue decompression, reduces the occurrence of hospital acquired p...

The process of switching one differentiated cell type into another cell type with a different form and function, such as transdifferentiation from hepatic stellate cells to myofibroblastic cells in liver fibrogenesis.
Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
Locomotor behavior not involving a steering reaction, but in which there may be a turning random in direction. It includes orthokinesis, the rate of movement and klinokinesis, the amount of turning, which are related to the intensity of stimulation.
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.

Organ transplantation is the moving of an organ from one body to another or from a donor site to another location on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ. The emerging field of regenerative ...
Clinical trials are a set of procedures in medical research conducted to allow safety (or more specifically, information about adverse drug reactions and adverse effects of other treatments) and efficacy data to be collected for health interventions (e.g...
