Journal of Cellular Biotechnology is a peer-reviewed international journal for advancing research activities in the field of cellular biotechnology. It serves as a medium for the publication of full papers, invited reviews, short communications, technical notes and letters to the Editor-in-Chief on all aspects of cellular biotechnology. This comprises molecular biological topics covering biochemical, chemical, pharmacological or bioprocess engineering aspects, as well as the development of novel biomaterials. Therefore, cellular biotechnology differs from biology, biochemistry, and other basic life sciences by its emphasis on using the knowledge of bioscience to solve important practical problems. Papers presenting information of a multidisciplinary nature - not suitable for publication in a journal devoted to a single discipline - are particularly welcome.
Manuscripts submitted for the
Journal of Cellular Biotechnology are expected to cover activities related to molecular diagnostics, the expansion of human primary cells for individualized therapies or drug testing, 2- and 3-dimensional co-culture techniques, cell line validation, tissue engineering, and stem cell biology for the treatment of human pathologies. This includes studies on the design of reactors and research on cellular biology and physiology of mammalian cells in vitro and in vivo, and tissue. Of special interest is the rational manipulation of reactions through metabolic engineering techniques or specific reactor operations that lead to biomaterials with unique properties. Also, biochemical and physiological studies of metabolism and enzymes as relevant for tissue culture cells, investigations at the molecular level including transcription/translation control; design and engineering of products by molecular strategies; engineering of cellular modification and transport systems such as post-translational protein modifications as well as protein and metabolite secretion; molecular strategies of screening for new or modified products (e.g. pharmaceuticals or bioactive compounds). In addition, investigations in preclinical animal experiments are welcome.
The endeavour of the Editor-in-Chief and publisher of the
Journal of Cellular Biotechnology is to bring together contributions from those working in various fields related to cell-cell or cell-material interactions all over the world. The editorial board members of the
Journal of Cellular Biotechnology are from those countries in Europe, Asia, Australia and America where appreciable work in cellular biotechnology is being carried out. Each editor takes responsibility to decide on the acceptance of a manuscript. He/she is required to have the manuscript appraised by two referees and may be one of them himself. The executive editorial office, to which the manuscripts have been submitted, is responsible for rapid handling of the reviewing process.
Abstract: Celecoxib (CLX) delivery and its enzyme-sensitive release from Inulin-d-alfa-tocopherol succinate (INVITE) nanomicelles are the main goals of this paper. CLX is a highly hydrophobic drug belonging to BCS class II (low solubility, high permeability). For this reason its formulation is problematic and its biopharmaceutical performances strongly depend from the applied delivery system. In the last years, INVITE nanomicelles has been shown their potential in the delivery of highly hydrophobic drugs such as curcumin and for this reason have been chosen as a good candidate for CLX delivery. Furthermore, due to the presence of ester bonds between INU and VITE it…has been supposed that the drug release could show enzyme-sensitive (esterase) behaviors. Thus CLX was loaded in INVITE nanomicelles, the loading was quantified and the physical stability was evaluated up to 90 days, finally, drug release studies in the presence or in the absence of the specific enzyme esterase were performed.

Abstract: Stenoses in arterial blood vessels by artherosclerotic processes can decrease the supply of downstream tissue dramatically. The implantation of stents by percutaneous coronary intervention is one method of choice to restore the physiological blood flow. In some cases in-stent re-stenoses by thrombotic events, vascular wall hyperplasia or endothelial dysfunction occur. Causes and nature underlying this processes are not fully understood. Aim of the present study was to study the re-stenotic processes after stent impress on a cellular and molecular level in vitro . Therefore, human arterial endothelial cells (HUAEC) were seeded on a model vascular wall intima consisting of…extracellular matrix secreted by bovine corneal endothelial cells. Subsequently, a pre-mounted balloon-expendable tubular stent made of 316 L was impressed through the HUAEC layer leading to an impairment of the vessel wall intima. After stent removal the wound healing process, HUAEC membrane integrity, vitality, proliferation and function were assessed. Immediately after stent impress an increased level of lactate dehydrogenase (LDH) was observed indicating an impairment of the cell membrane integrity. After 24 h baseline LDH values presented again. HUAEC vitality adjacent to the stent impress induced wound was normal (investigated by inverted microscopy). The proliferation of HUAEC was the highest in the direct vicinity of the stent impress induced wound. Prostacyclin and nitric oxide decreased significantly indicating a temporary loss of cell function. These results could imply that the healing process of the endothelial cell lesion is superior to the maintenance of vascular tonicity and downregulation of platelet aggregation.
