EXPRESSION PATTERN OFHISTONE H3 SUBTYPES INARTICULAR CHONDROCYTESAnna Kulczycka 1 *, Joanna Orchel 2 , Arkadiusz Orchel 3 ,Zofia Dzierżewicz 3 , Ilona Bednarek 11Department of Biotechnology and Genetic Engineering,Medical University of Silesia,Narcyzów 1, 41-206 Sosnowiec, Poland2Department of Molecular Biology,Medical University of Silesia,Narcyzów 1, 41-206 Sosnowiec, Poland3Department of Biopharmacy,Medical University of Silesia,Narcyzów 1, 41-206 Sosnowiec, Poland* e-mail: a_kulczycka@wp.plAbstractThree-dimensional cell culture used for tissueengineering has its own rules and directions. Thereis a deficiency of proliferative markers suitable fortissue engineering research when cells are crosslinkedin network of fibers or suspended in hydrogel.It limits cell harvesting or impairs the flow to cell areaconventional chemicals used as proliferative markers.According to current published data, the expressionof replication-dependent histone H3 genes couldbe novel proliferative marker of cells. The intensivesynthesis of H3 histones is tightly correlated with DNAsynthesis and H3 mRNA is rapidly degraded when theS phase is completed or inhibited by cell cycle inhibitors.Based on this relation, non-dividing cells containno H3 mRNA. The aim of the study was to determineexpression pattern of replication-dependent H3 subtypesand tissue-specific H3/t subtype in normal humanconnective tissue cells. Analyzed cellular model waschondrocytes cell line due to the phenomenon thatarticular cartilage doesn’t have natural ability to healits injuries, consequently development of cartilageengineering is necessary. Evaluation of expressionpattern was performed using Reverse TranscriptionPCR and reaction products were visualized on the gelelectrophoresis. This study demonstrated that RT-PCRtechnique can be successfully used to study the expressionof different histone H3 subtypes. Presentedelectrophoregram showed differential expression ofthe analyzed subtypes (no expression of H3/g andH3/t subtypes). Incubation with sodium butyrate andquantitative Real Time PCR enabled quantificationof mRNA level of selected H3/d subtype. This partof study showed a significant reduction in the mRNAlevel of H3/d when the sodium butyrate was added.Obtained results indicated the possibility of using theexpression of individual histone H3 subtype as a newproliferative marker.Keywords: histone H3 subtypes, proliferative marker,chondrocytes, RT-PCR, sodium butyrate.[Engineering of Biomaterials <strong>113</strong> (2012) 2-5]Self-assembling MicellesObtained from PLLA/PEG andPDLA/PEG Block Copolymersin Aqueous SolutionsXiaohan WU, Suming LI*Max Mousseron Institute on Biomolecules, UMR CNRS5247, University Montpellier I, 34060 Montpellier, France* e-mail: lisuming@univ-montp1.frAbstractA series of polylactide-poly(ethylene glycol) (PLA-PEG) block copolymers were synthesized by ring-openingpolymerization of L- or D-lactide in the presenceof mono- or dihydroxyl PEG, using nontoxic zinc lactateas catalyst. Micelles were then prepared by directdissolution of the obtained copolymers in aqueousmedium without heating or using any organic solvents.Aqueous gel permeation chromatography and dynamiclight scattering measurements were carried out tocharacterize the resulting micelles. Generally, mixedmicelles containing both PLLA/PEG and PDLA/PEGcopolymers appear lager and more compact comparedto single ones. However, the size of mixed micellesis smaller than that of single ones which exhibit an anisotropicstructure since stereocomplexation disfavorsthe formation of anisotropic micelles. The copolymerparameters such as structures, molar mass and PEGfraction strongly influence the formation of anisotropicmicelles, and thus lead to various micellar sizes.Keywords: polylactide, poly(ethylene glycol), stereocomplexation,self-assembly, anisotropy[Engineering of Biomaterials <strong>113</strong> (2012) 6-8]

The copolymerization ofTMC and CL was performed in bulk at 120°C. Theobtained copolymers were characterized by multiblockmicrostructure. The highest reactivity rate was demonstratedby trimethylene carbonate in comparison withε-caprolactone monomer. The thermal and mechanicalproperties of the copolymers were strongly dependenton the monomer composition.

Metronidazole was used as radiosensitizer.The changes of copolymers chain microstructure weremonitored during 16 weeks of hydrolytic degradationof material in artificial Cerebro-spinal Fluid Solution.This study shows distinct differences in the rate ofcopolymer degradation and changes of the degreeof randomness, directly connected with the type ofcomonomers and the comonomeric molar ratio. During16 weeks of hydrolytic degradation, copolymers withL-lactidyl units remain resistant to hydrolysis whilematerials with D,L-lactidyl units are completely degraded.Examined materials can be used as carriers ofagents for different types of short-, mid- and long-termtherapies based on control release systems.Keywords: biodegradable polyesters, NMR spectroscopy,hydrolytic degradation, polymeric chainmicrostructure[Engineering of Biomaterials <strong>113</strong> (2012) 16-18]HARNESSING BIOPOLYESTERSIN THE DESIGN OF FUNCTIONALMATERIALS FOR BIOMEDICALAPPLICATIONSEstelle Renard, Julien Babinot, Pierre Lemechko,Julien Ramier, Gwenaelle Vergnol, Davy Louis Versace,Daniel Grande, Valerie Langlois*1Institut de Chimie et des Matériaux Paris Est,UMR 7182 CNRS- Université Paris Est Créteil,94320 Thiais, France* e-mail: langlois@icmpe.cnrs.frAbstractThe present contribution illustrates the versatilityof poly(3-hydroxyalkanoate)s (PHAs) in the design ofa wide variety of biodegradable and/or biocompatiblemacromolecular architectures with controlled degradability.Firstly, functionalized PHAs were preparedfrom unsaturated PHAs. Pendant double bonds havebeen turned into carboxyl, hydroxyl, alkyne or epoxygroups. These reactive functions were used for furthergrafting hydrolyzable polylactide (PLA) or poly(ε-caprolactone)(PCL) as well as hydrophilic poly(ethyleneglycol) (PEG). Additionally, block copolymers with aPLA, PCL or PEG segment have been prepared byring-opening polymerization or “click” chemistry froma PHA oligomeric macroinitiator. Functional PHAs representbiodegradable aliphatic polyesters with manypossibilities to tune physico-chemical characteristics,such as hydrophilicity and degradation rate, thus makingthe resulting materials suitable as devices for drugdelivery or as scaffolds for tissue engineering. Herein,we address the recent trends in the synthesis of thesepolymeric materials and their applications in controlleddrug delivery and tissue engineering.Keywords: poly(3-hydroxyalkanoate)s, block andgraft copolymers, drug delivery, tissue engineering[Engineering of Biomaterials <strong>113</strong> (2012) 19-22]

All applicable biomedicalmaterials must be biocompatible, which meansthat they cannot cause toxic, cytotoxic, allergic, orcarcinogenic reactions. The first study evaluating thebiocompatibility of the material is determination of itscytotoxicity.The purpose of this study was to assess the biocompatibilityof poly(L-lactide-co-glycolide-co-trimethylene-carbonate)75:13:12, synthesized using Zr(Acac) 4as an initiator of polymerization. The terpolymer wasdegraded for 30, 60 and 90 days at 37şC in water.The effect of degradation products on the growth ofhuman articular chondrocytes was determined usingthe sulforhodamine B assay. The examined terpolymerwas characterized by means of NMR spectroscopy,GPC and DSC. The results showed that the studiedterpolymer was biocompatible with tested cells.Keywords: Shape-memory polymers (SMP), biodegradablepolymers, cytotoxicity, degradation products,in vitro, biocompatibility of terpolymer[Engineering of Biomaterials <strong>113</strong> (2012) 23-25]Degradation process ofTMC-based polymers bymass spectrometryJoanna Jaworska*, Janusz Kasperczyk, MagdalenaMaksymiak, Grażyna Adamus, Piotr DobrzyńskiCentre of Polymer and Carbon Materials,Skłodowskiej- Curie 34 st., 41-819 Zabrze, Poland* e-mail: maciejowska@wp.plAbstractThis paper presents results of degradation processinvestigations of resorbable poly(lactide-trimethylenecarbonate).
