Cardiovascular diseases, including myocardial infarction and heart failure, are the main causes of death worldwide. Classical pharmacological treatment may halt, but cannot reverse the underlying disease process. Cellular cardiomyoplasty has the potential to reconstruct myocardium in situ; yet, it is hampered by poor cell survival, engraftment, and differentiation. Tissue engineering has emerged as an alternative cell-ba Read More

Chronic ischemic heart disease remains a major cause of morbidity and mortality worldwide. Although revascularisation strategies and pharmaceutical therapy are able to delay ventricular remodelling, until today no therapeutic strategy is available that might prevent or even reverse this process of remodelling and consequent ventricular failure. In the recent past, experimental and clinical studies have demon Read More

In spite of increasing numbers of publications about cell replacement therapies in various neurodegenerative diseases, reports on therapeutic benefits are still rare due to the huge array of parameters affecting the clinically relevant outcome. Limiting conditions can be attributed to origin and number of cells used for transplantation, their in vitro storage, propagation and/or predifferentiation. In addition, the ability of these Read More

Radial glial cells represent a subpopulation of secondary neural precursor cells that differentiate from neuroepithelial progenitors and are transiently found in the developing CNS of mammals. There is ample evidence for a temporal and spatial arrangement of increasingly committed radial glial cells that is of critical importance for the organisation and specification of different brain regions. For the human ganglionic e Read More

Stem cells possess great promise as therapeutic tools for neurological disorders such as neurodegenerative diseases (Parkinson's disease and Huntington's disease), cerebrovascular diseases (stroke), neurotraumata (spinal cord injury) and demyelinating diseases (multiple sclerosis). This aspiration is based on the cells` ability to maintain a status of self-renewal and to differentiate into the various cell types of an organism. Read More

Gene delivery has attracted increasing interest as a highly promising therapeutic method to treat various diseases, including both genetic and acquired disorders. Viral-vectors based gene delivery can achieve higher transduction efficiency and long-term gene expression, but they may be associated with some shortcomings, such as immunogenicity, carcinogenicity, poor target cell specificity, inability to transfer large size g Read More

Heart failure is a life threatening disorder in worldwide and many papers reported about myocardial regeneration through surgical method induced by LVAD, cellular cardiomyoplasty (cell injection), tissue cardiomyoplasty (bioengineered cardiac graft implantation), in situ engineering (scaffold implantation), and LV restrictive devices. Some of these innovated technologies have been introduced to clinical settings. This review art Read More

Drug-eluting stents (DES) have revolutionized the treatment of coronary artery blockage by tremendously reducing the rate of in-stent restenosis and the necessity of repeat revascularization compared to bare-metal stents. They are also gaining increasing importance in other medical fields such as the treatment of certain localized tumors and in glaucoma therapy. DES generally contain most potent drugs, e.g. immunosuppr Read More

Beyond their originally sole mechanical function, current drug-eluting stents (DES) implement the concept of local drug delivery for the re-opening of stenotic arterial vessels, and for prevention of in-stent restenosis as one of the major limitations of conventional bare metal stents (BMS). Current DES consist of a permanent metallic stent platform and an active agent being released from a drug-incorporated polymer coati Read More

Computer assisted biofabrication of fully functional living tissue for regenerative medicine involves generation of complex three-dimensional constructs consisting of living cells and biomaterials. Laser BioPrinting (LaBP) based on laser-induced forward-transfer provides unique possibilities for the deposition of different living cells and biomaterials in a well-defined 3D structure. LaBP can be applied to generate scaffold-free 3 Read More

Glaucoma is a common cause of blindness in industrialized countries and is the most frequent cause of irreversible blindness worldwide. Since raised intraocular pressure (IOP) has been implicated as the major risk factor, the main goal of all glaucoma treatment is to reduce IOP sufficiently to prevent continuous irreversible retinal ganglion cell damage and progression of visual field loss. Pharmacological reduction of IOP is fi Read More

Cochlear implants have evolved to become the treatment of choice for severely hearing-impaired patients. Speech signals are picked up by a microphone, processed and then delivered to the stimulating electrodes (the current maximum number being 22) that are placed on an electrode array implanted into the scala tympani of the cochlea. The target cells of electrical stimulation, the spiral ganglion cells (SGCs), are locat Read More

The use of botulinum neurotoxins (BoNTs) for therapeutic purposes in neuromuscular disorders and peripheral hypercholinergic conditions as well as in aesthetic medicine is widespread and common. BoNTs are also able to block the release of a wide range of transmitters from presynaptic boutons. Therefore, application of BoNTs directly in the central nervous system (CNS) is currently under study with respect to basic rese Read More
