SuperNatural: A Database of Available Natural Compounds
Melanie Füllbeck, Mathias Dunkel and Robert Preissner

The majority of marketed drugs are natural compounds or derivatives thereof. The compounds availability is often unclear. Therefore we have compiled a database of ~50,000 natural compounds. Starting point for in silico screenings are about 2,500 well-known, classified natural compounds or imported molecules. Possible medical applications can be detected and about three million conformers computed to account for the flexibility during usage of the 3D-superposition algorithm.

Nucleic Acid Reagents and Experimental Results in the NCBI Probe Database
Svetlana Iazvovskaia, Ilene Karsch Mizrachi, Kirill Rotmistrovsky, and Savani Tatake

Five years ago, the NCBI Probe database (ProbeDB) was established to provide a centralized archive of molecular probes used in biomedical applications. Currently ProbeDB contains around 10 million probes of 65 types including gene silencing agents, in situ hybridization probes, and probes for variation analysis and genome mapping. Presently, ProbeDB is the largest and most extensive database of this type available in public domain.

Regulatory requirements in the development of advanced therapy products (cell-, gene therapy, tissue engineering products)
Marianne Groeneveld

Regulatory authorities are active to ensure a good regulatory environment for somatic cell therapy-, gene therapy- and tissue engineering products (in the EU known as ‘Advanced Therapy Medicinal Products’). Both the EMEA and the FDA have, amongst others, issued guidelines to address the specific aspects of these products

EFFICIENT LARGE SCALE EXPANSION OF HUMAN EMBRYONIC STEM CELLS: COMPARISON OF 4 DIFFERENT SOLUTIONS FOR SINGLE CELL PASSAGING

Human embryonic stem cells (hESC) are promising for tissue engineering (TE) purposes due to their unique properties. However, the current standard mechanical passaging technique is time consuming and labour intensive, thus limiting the rate of hESC expansion and possible TE experiments.

Immunomodulatory Properties of Adipose-Derived Stem Cells Cultured in Autologous Serum
Eivazova G, Berzins U, Zvaigzne A, Skrastina D, Bogdanova A, Kozlovska T, Lejnieks A

This study investigated whether adipose-derived stem cells (ADSC), cultivated in the medium containing autologous serum, maintain immunomodulatory properties of MSC. Obtained cells were CD73, CD90 and CD105 positive but CD34 and CD45 negative. ADSC underwent in vitro differentiation into adipocytes, osteoblasts and chondroblasts. Immunomodulatory properties of ADSC were investigated by blast transformation reaction and significant suppression of T lymphocyte proliferation was induced in a dose d

Development of cell culture system on the basis of adult stem cells for modeling of HBV infection
Zajakina A, Berzins U, Bogdanova A, Kozlovska T

Efforts to elucidate the mechanisms by which HBV infects hepatocytes and causes liver damage have been hampered by the strict virus host range and a lack of suitable cell culture and animal models of HBV infection/replication. The present study has established and elucidated a novel HBV infection/replication in vitro model system based on adipose-derived stem cells differentiated into human hepatocyte-like cell line.

FOXP3 Gene Expression in Multiple Sclerosis patients before and after Mesenchymal Stem Cell therapy
Maryam Mohajeri, Mandana Mohyeddin Bonab, Behrooz Nikbin, Ali Farazmand

Multiple Sclerosis (MS) is a chronic inflammatory demyelinating disorder of the CNS. No successful treatment for MS, but one therapeutic strategy in research is the use of bone marrow-derived mesenchymal stem cells (MSC). We studied a group of MS patients who underwented MSCs, assayed for expression of a transcription factor, FOXP3, as a specific marker of MS amelioration in peripheral blood. qRT-PCR on PBMCs showed higher FoxP3 levels.

Three-Dimensional Cell Culture Within A Biomimetic Hydrogel Based On Chitosan And Hyaluronan

A growing demand for study of cells within biologically realistic, in vitro, microenvironments requires a paradigm shift in cell culture technology: from cell culture on 2-D, rigid substrata to cell growth within a 3-D space, defined by malleable materials composed of biologically “smart” compounds.1, 2 Therapeutic issues addressed by tissue engineering and regenerative medicine require similar materials, customized for human application in a wide variety of treatment circumstances: ranging

Characterization of enamel and dentin protein expression in bioengineered human tooth tissues
Sheila Soroushian1, Monica Duailibi2, Silvio Duailibi2, Weibo Zhang1, Robert Litterman1, Ivy Pruit1, Pamela C. Yelick1

Here we have used previously described methods to bioengineer teeth from human dental stem cells (hDSC). We we were able to demonstrate that dissociated hDSC-seeded polymer constructs can form bioengineered teeth that are morphologically similar to natural human teeth at both gross and microscopic levels. We anticipate that further modifications of this approach will eventually result in reliable methods to bioengineer replacement teeth in humans.
