    We proposed the fabrication of a gel composed primarily of calcium phosphate (CP) nanoparticles (NPs). Here, the additive of citric acid (Citr), which is an organic molecule present in bone tissues that chelates with calcium ions, was investigated during the synthesis of the CP NPs, with a focus on a gel-like aggregation state. As a result, the Citr-coordinated CP NP (Citr/CP NP) sols exhibiting different thermal responses ((1) maintenance of a sol state, (2) formation of a stable gel-like aggregation state, and (3) formation of a thixotropic gel-like aggregation state) were successfully prepared by controlling the nucleation and nanoparticle growth temperatures during the synthesis. Specifically, the sol of the highly anisotropic Citr/CP NP nucleated at 40 °C maintained its sol state after heat at 37.5 °C, whereas the isotropic Citr/CP NP at 4 °C formed the gel-like aggregation state upon the heat. The sol grown at 4 °C formed a stable gel-like aggregation state that was resistant to external force, whereas that at 40 °C exhibited thixotropy, which is a property commonly observed in synovial fluid. The gelation would be attributed to the precipitation of calcium citrate tetrahydrate, which exhibited retrograde solubility and promoted cross-linking among the CP NPs.

    Tissue engineering technology can be used to reconstruct biological tissues or organs with lesions or loss of function and minimize the damage to patients during the repair process. As an important and fundamental component of tissue engineering, the development of cell culture technology has attracted widespread attention. In particular, the design of cell culture substrates that can provide good cell culture properties has been extensively studied. The main commercially available culture substrate is tissue culture polystyrene (TCPS), but the survival rate of cells cultured on TCPS after in vivo transplantation is relatively low, which is considered to result from the environmental differences in composition and structure between TCPS and biological tissues. Accordingly, we summarized the current status of cell culture, the issues associated with culture substrates, and the conditions required for good cell culture substrates. In particular, the culture substrate needs to be highly transparent for optical microscopy. Moreover, since cell adhesion occurs by recognizing the proteins adsorbed on the substrate, it is proposed to control the protein adsorption state through nanostructures. Thus, hydroxyapatite (HA) with good biocompatibility has attracted attention, and its properties and the possibility of forming a transparent nanostructured film have been summarized. Furthermore, based on the inorganic-organic composite structures in living bodies, such as bone tissue, the coordination between HA nanoparticles and organic citric acid molecules has also been considered to fabricate functional films for producing new cell culture substrates with a wider range of applications. In this review, the basis of cell culture technology is systematically explained, and the design concepts of culture substrate surfaces for achieving favorable cell culture properties are highlighted. Surface functionalization of HA nanoparticle films is proposed to enhance protein adsorption and cell adhesion, and is expected to have wide applications in the field of regenerative medicine.

    In the biomedical fields of bone regenerative therapy, the immobilization of proteins on the bioceramic particles to maintain their highly ordered structures is significantly important. In this review, we comprehensively discussed the importance of the specific surface layer, which can be called "non-apatitic layer", affecting the immobilization of proteins on particles such as hydroxyapatite and amorphous silica. It was suggested that the water molecules and ions contained in the non-apatitic layer can determine and control the protein immobilization states. In amorphous silica particles, the direct interactions between proteins and silanol groups make it difficult to immobilize the proteins and maintain their highly ordered structures. Thus, the importance of the formation of a surface layer consisting of water molecules and ions (i.e., a non-apatitic layer) on the particle surfaces for immobilizing proteins and maintaining their highly ordered structures was suggested and described. In particular, chlorine-containing amorphous silica particles were also described, which can effectively form the surface layer of protein immobilization carriers. The design of the bio-interactive and bio-compatible surfaces for protein immobilization while maintaining the highly ordered structures will improve cell adhesion and tissue formation, thereby contributing to the construction of social infrastructures to support super-aged society.
