Abstract
A surface of biomaterials is known to affect the behavior of cells after their adhesion on the surface, indicating that surface characteristics of biomaterials play an important role in cell adhesion, proliferation, and differentiation. To assess the effects of functional groups on biomaterial surface, normal human osteoblasts (NHOsts) were cultured on surfaces coated with self-assembled monolayers (SAMs) containing various functional groups, and the adhesion, proliferation, differentiation, and gap junctional intercellular communication (GJIC) of the NHOsts were investigated. In the case of SAM with terminal methyl groups (hydrophobic surface), NHOst adhesion and proliferation was less prevalent. In contrast, NHOsts were adhered well on SAMs with hydroxyl, carboxyl, amino, phosphate, and sulfate group, which are relatively hydrophilic, their proliferation and differentiation level were dependent on the type of functional groups. Especially, when they were cultured on either SAMs with phosphate or sulfate group, both their alkaline phosphate activity and the calcium deposition by them were enhanced more than those cultured on a collagen-coated dish. More interestingly, GJIC of NHOsts, which has been reported to play a role in cell differentiation as well as homeostasis of cells, were not significantly different among the SAM surfaces tested. These suggest that a specific functional group on a material surface can regulate NHOst adhesion, proliferation, and differentiation via cell-functional group interaction without influencing their homeostasis.

Abstract
Endothelial cell seeding, a promising method for improving the performance of vascular grafts, often requires immobilizing biological molecules on the surface of the substrate material. In this study, chitosan (CS) and sulfated chitosan (SCS) multilayers were coated on pure titanium using a layer-by-layer self-assembly technique. The CS—SCS multilayer growth was carried out by first depositing a single layer of positively charged poly(L-lysine) (PLL) on the NaOHtreated titanium substrate, followed by alternate deposition of negatively charged SCS and positively charged CS, and terminated by an outermost layer of SCS. Platelet-rich plasma (PRP) and endothelial cells were seeded on NaOH treated titanium and CS—SCS coated titanium samples, respectively, to evaluate the adhesion and activation of platelets and the behavior of endothelial cells in vitro. The multilayer processed surfaces displayed reduced platelet adhesion and activation, and promoted endothelial cell attachment and growth in vitro. This approach may be used for the fabrication of titanium-based vascular implant surfaces for endothelial promotion.

Abstract
The bioactivity of a novel composite of carbonate-containing low-crystallinity nanoparticle hydroxyapatite (HA) and a chitosan—phosphorylated chitosan polyelectrolyte complex (PEC) was evaluated in vitro and in vivo. The HA—PEC nanocomposite with complicated porous structure was prepared by a biomimetic method. An acidic chitosan (polycation) solution containing calcium and phosphate ions (6 mM Ca2+, Ca/P: 1.67) was added into phosphorylated chitosan (polyanion) solution; the formation of PEC and the controlled HA crystal growth were co-organized in alkaline solution. The material was co-cultured with rat osteoblasts in vitro, and implanted into rabbit femur marrow cavities. The results indicate that the PEC—HA composite promoted osteoblast adhesion, morphology, proliferation, and differentiation in vitro; the bone tissue response to the material histologically showed that it was bioactive, as well as biodegradable. The HA—PEC composite shows promise as a bone-repair material.

Abstract
To simulate extra-cellular matrix, a novel three-dimensional scaffold of polyelectrolyte complex (PEC) hydrogel as an osteoblast carrier was synthesized. First, chitosan, a natural glycosaminoglycan, was modified by phosphorylation to obtain a water-soluble phosphorylated chitosan (P-content: 10.7 mass%). The PEC hydrogel was then formed from equal volumes of 0.173 mass% phosphorylated chitosan in water and 1 mass% chitosan in 1% (V/V) acetic acid solution. Rat osteoblasts were seeded in the hydrogel. The PEC hydrogel had a three-dimensional hierarchically-porous structure and good cytobiocompatibility for osteoblasts in vitro. It is concluded that the PEC hydrogel is a promising material as an osteoblast carrier.

Abstract
Polyelectrolyte complexes (PEC) were prepared from chitosan as the polycation and several synthesized functional anion polysaccharides, and their effects on cell attachment, morphology, proliferation and differentiation were estimated using normal human osteoblasts (NHOst). After a 1-week incubation, PEC made from polysaccharides having carboxyl groups as polyanions showed low viability of NHOst on it although the NHOst on it showed an enhancement in their differentiation level. On the other hand, NHOst on PEC made from sulfated or phosphated polysaccharides showed similar attachment and morphology to those on the collagen-coated dish. When the number of NHOst was estimated after 1 week, the number on the PEC was ranged from 70% to 130% of those on the collagen-coated dish, indicating few effects of these PEC on cell proliferation. In addition, NHOst on PEC films made from sulfated polysaccharides differentiated to a level very similar to that observed on the collagen-coated dish, indicating that these PEC films maintain the normal potential of NHOst to both proliferate and differentiate. Measurement of gap junctional intercellular communication of NHOst on PEC revealed that PEC did not inhibit communication, suggesting that PEC films have few effects on cell homeostasis. Thus, PEC made from the sulfated polysaccharide may be a useful material as a new scaffold for bone regeneration.

Abstract
In this study, we examined the interaction of the osteoblast which forms bone and sulfated hyaluronan (SHya). For the purpose of the creation of a new functional polysaccharide, we introduced a sulfate group in hyaluronan (Hya) of high molecular weight, and SHya of high molecular weight could be obtained for the first time. When rat calvarial osteoblast (rOB) cells were cultured with a high concentration of SHya, they formed aggregated spheroids after 4h and the spheroids grew to about 200microm after 24h. We examined the expression of cell adhesion molecules in order to clarify the mechanism of aggregate formation. The N-cadherin (N-cad) and Connexin43 (Cx43) expression level of rOB cells cultured with SHya remarkably increased after 2h. A difference in the expression of Integrin beta1 (Intbeta1) could not be observed between the SHya addition and control group. The alkaline phosphatase (ALPase) activity of rOB cells cultured with SHya after 8h was significantly enhanced in comparison with control. Therefore, the sulfate group of SHya seems to enhance expression of cell adhesion protein such as N-cad and Cx43, resulting in aggregate formation and further remarkable induction of the ALPase activity of rOB cells.

Abstract
The aim of this review was to provide a detailed overview of physical chitosan hydrogels and related networks formed by aggregation or complexation, which are intended for biomedical applications. The structural basis of these systems is discussed with particular emphasis on the network-forming interactions, the principles governing their formation and their physicochemical properties. An earlier review discussing crosslinked chitosan hydrogels highlighted the potential negative influence on biocompatibility of covalent crosslinkers and emphasised the need for alternative hydrogel systems. A possible means to avoid the use of covalent crosslinkers is to prepare physical chitosan hydrogels by direct interactions between polymeric chains, i.e. by complexation, e.g. polyelectrolyte complexes (PEC) and chitosan/poly (vinyl alcohol) (PVA) complexes, or by aggregation, e.g. grafted chitosan hydrogels. PEC exhibit a higher swelling sensitivity towards pH changes compared to covalently crosslinked chitosan hydrogels, which extends their potential application. Certain complexed polymers, such as glycosaminoglycans, can exhibit interesting intrinsic properties. Since PEC are formed by non-permanent networks, dissolution can occur. Chitosan/PVA complexes represent an interesting alternative for preparing biocompatible drug delivery systems if pH-controlled release is n/ot required. Grafted chitosan hydrogels are more complex to prepare and do not always improve biocompatibility compared to covalently crosslinked hydrogels, but can enhance certain intrinsic properties of chitosan such as bacteriostatic and wound-healing activity.
