    Abstract Mesenchymal stromal/stem cells (MSCs) are promising candidates for regenerative medicine owing to their self-renewal properties, multilineage differentiation, immunomodulatory effects, and angiogenic potential. MSC spheroids fabricated by 3D culture have recently shown enhanced therapeutic potential. MSC spheroids create a specialized niche with tight cell-cell and cell-extracellular matrix interactions, optimizing their cellular function by mimicking the in vivo environment. Methods for 3D cultivation of MSCs can be classified into 2 main forms: static suspension culture and dynamic suspension culture. Numerous studies have reported the beneficial influence of these methods on MSCs, which is displayed by increased differentiation, angiogenic, immunomodulatory, and anti-apoptotic effects, and stemness of MSC spheroids. Particularly, recent studies highlighted the benefits of dynamic suspension cultures of the MSC spheroids in terms of faster and more compact spheroid formation and the long-term maintenance of stemness properties. However, only a few studies have compared the behavior of MSC spheroids formed using static and dynamic suspension cultures, considering the significant differences between their culture conditions. This review summarizes the differences between static and dynamic suspension culture methods and discusses the biological outcomes of MSC spheroids reported in the literature. In particular, we highlight the advantages of the dynamic suspension culture of MSC spheroids and contemplate its future applications for various diseases.

    The transcriptional regulation of induced pluripotent stem cells (iPSCs) holds promise for their directed differentiation into ameloblasts, which are usually lost after tooth eruption. Ameloblast differentiation is regulated by multiple signaling molecules, including bone morphogenetic proteins (BMPs). Epiprofin (Epfn), a transcription factor, is expressed in the dental epithelium, and epithelial Epfn overexpression results in ectopic ameloblast differentiation and enamel formation in mouse incisor, a striking phenotype resembling that of mice with deletion of follistatin (a BMP inhibitor). However, it remains unknown whether and how Epfn transcriptional activation promotes ameloblast induction from mouse iPSCs. Here, we generated doxycycline-inducible Epfn-expressing mouse iPSCs (Epfn-iPSCs). Ameloblasts, which are characterized by positive staining for keratin 14 and amelogenin and alizarin red S staining, were successfully derived from Epfn-iPSCs based on a stage-specific induction protocol, which involved the induction of the surface ectoderm, dental epithelial cells, and ameloblasts at stages 1, 2, and 3, respectively. Epfn activation by doxycycline at stages 2 and/or 3 decreased cell proliferation and promoted ameloblast differentiation, along with the upregulation of p-Smad1/5/8, a key regulator of the BMP-Smad signaling pathway. Gene analysis of the BMP-Smad signaling pathway-associated molecules revealed that Epfn activation decreased follistatin expression at stage 2, but increased BMP2/4/7 expression at stage 3. Perturbations in the ameloblast differentiation process were observed when the BMP-Smad signaling pathway was inhibited by a BMP receptor inhibitor (LDN-193189). Simultaneous LDN-193189 treatment and Epfn activation largely reversed the perturbations in ameloblast induction, with partial recovery of p-Smad1/5/8 expression, suggesting that Epfn activation promotes ameloblast induction from mouse iPSCs partially by upregulating BMP-Smad activity. These results reveal the potential regulatory networks between Epfn and the BMP-Smad pathway and suggest that Epfn is a promising target for inducing the differentiation of ameloblasts, which can be used in enamel and tooth regeneration.

    Mesenchymal stem cells (MSCs) exhibit self-renewal, multi-lineage differentiation potential and immunomodulatory properties, and are promising candidates for cellular therapy of various tissues. Despite the effective function of MSCs, the gradual loss of stem cell characteristics that occurs with repeated passages may significantly limit their therapeutic potential. A novel 3D shaking method was previously established to generate MSC spheroids in growth medium (GM-spheroids) and successfully maintain the multipotency of expanded MSCs, yet the expression of MSC-related genes was still low. In this study, we used a neurosphere culture technique to optimize the shaking culture method using human bone marrow-derived MSCs (BM-MSCs). MSC spheroids generated in neurosphere medium (NM-spheroids) maintained high expression of MSC-related genes during 3 weeks of prolonged shaking culture. Moreover, NM-spheroids generated from expanded MSCs showed high viability, upregulation of MSC-related and immune-related genes, and recovery of differentiation potential in vitro. Expanded adherent MSCs, GM-spheroids, and NM-spheroids were transplanted into a rat femur bone defect model to investigate their therapeutic potential in bone repair. Adherent MSCs and GM-spheroids showed delayed bone healing. In contrast, NM-spheroids showed high transplantation efficiency and enhanced bone regeneration. These data suggest that NM-spheroids generated using modified neurosphere culture conditions under continuous shaking recovered their stem cell characteristics in vitro and enhanced bone regeneration in vivo. Therefore, NM-spheroids should have great clinical potential for bone and tissue regenerative therapies as a stem cell-based biomaterial therapy.

    Amelogenin comprises ~90% of enamel proteins; however, the involvement of Amelx transcriptional activation in regulating ameloblast differentiation from induced pluripotent stem cells (iPSCs) remains unknown. In this study, we generated doxycycline-inducible Amelx-expressing mouse iPSCs (Amelx-iPSCs). We then established a three-stage ameloblast induction strategy from Amelx-iPSCs, including induction of surface ectoderm (stage 1), dental epithelial cells (DECs; stage 2), and ameloblast lineage (stage 3) in sequence, by manipulating several signaling molecules. We found that adjunctive use of lithium chloride (LiCl) in addition to bone morphogenetic protein 4 and retinoic acid promoted concentration-dependent differentiation of DECs. The resulting cells had a cobblestone appearance and keratin14 positivity. Attenuation of LiCl at stage 3 together with transforming growth factor β1 and epidermal growth factor resulted in an ameloblast lineage with elongated cell morphology, positivity for ameloblast markers, and calcium deposition. Although stage-specific activation of Amelx did not produce noticeable phenotypic changes in ameloblast differentiation, Amelx activation at stage 3 significantly enhanced cell adhesion as well as decreased proliferation and migration. These results suggest that the combination of inducible Amelx transcription and stage-specific ameloblast induction for iPSCs represents a powerful tool to highlight underlying mechanisms in ameloblast differentiation and function in association with Amelx expression.

    Mesenchymal stromal/stem cells (MSCs), which generally expand into adherent monolayers, readily lose their proliferative and multilineage potential following repeated passages. Floating culture systems can be used to generate MSC spheroids, which are expected to overcome limitations associated with conventional adherent cultures while facilitating scaffold-free cell transplantation. However, the phenotypic characteristics of spheroids after long-term culture are unknown. In addition, regenerative therapies require new culture systems to maintain their undifferentiated state. In this study, we established a novel culture method employing three-dimensional (3D) "shaking" to generate MSC spheroids using bone marrow derived MSCs. Floating 3D cultures of mouse or human MSCs formed spheroids after shaking (85-95 rpm), within 1 month. These spheroids maintained their osteogenic-, adipogenic-, and chondrogenic-differentiation capacity. The adipogenic-differentiation capacity of adherent cultured mouse and human MSCs, which is lost following several passages, was remarkedly restored by shaking-culture. Notably, human MSC spheroids exhibited a renewable "undifferentiated MSC-pool" property, wherein undifferentiated MSCs grew from spheroids seeded repeatedly on a plastic culture dish. These data suggest that the shaking-culture method maintains and restores multipotency that is lost following monolayer expansion and thereby shows potential as a promising strategy for regenerative therapies with mesenchymal tissues.

    Oxidative stress on transplanted bone marrow-derived mesenchymal stem cells (BMSCs) during acute inflammation is a critical issue in cell therapies. N-acetyl-L cysteine (NAC) promotes the production of a cellular antioxidant molecule, glutathione (GSH). The aim of this study was to investigate the effects of pre-treatment with NAC on the apoptosis resistance and bone regeneration capability of BMSCs. Rat femur-derived BMSCs were treated in growth medium with or without 5 mM NAC for 6 h, followed by exposure to 100 μM H2O2 for 24 h to induce oxidative stress. Pre-treatment with NAC significantly increased intracellular GSH levels by up to two fold and prevented H2O2-induced intracellular redox imbalance, apoptosis and senescence. When critical-sized rat femur defects were filled with a collagen sponge containing fluorescent-labeled autologous BMSCs with or without NAC treatment, the number of apoptotic and surviving cells in the transplanted site after 3 days was significantly lower and higher in the NAC pre-treated group, respectively. By the 5th week, significantly enhanced new bone formation was observed in the NAC pre-treated group. These data suggest that pre-treatment of BMSCs with NAC before local transplantation enhances bone regeneration via reinforced resistance to oxidative stress-induced apoptosis at the transplanted site.

    Induced pluripotent stem (iPS) cells are an attractive cell source in regenerative medicine; however, some problems must be overcome to improve clinical applications. iPS cells generated using the genomic integration method increase the risk of tumor generation because of transgene reactivation and the disruption of endogenous genes. The somatic cell sources of iPS cells also affect teratoma formation. Therefore, it is important to select a suitable cell source from among adult somatic cells, to generate iPS cells using a transgene insertion-free method, and to screen for good iPS clones that do not contain any differentiation-resistant cells after differentiation induction. Recently, we reported a method for obtaining high-quality iPS cells using purified mesenchymal stem cells (MSCs). In this report, we produced genomic integration-free iPS cells from adult tissues, purified MSCs, and tail tip fibroblasts using the Sendai virus. Then, we evaluated the residual undifferentiated cells in secondary neurospheres generated from retroviral induction iPS cell lines and non-integration iPS cell lines derived from adult MSCs. As a result, we could generate integration-free iPS cells only from MSCs. Nevertheless, some iPS cell lines generated by the non-integration method contained undifferentiated cells. Interestingly, the integration-free iPS cells that could not differentiate correctly showed a higher side scatter (SSC) intensity than the other ES/iPS cells. Some somatic cell-derived iPS cells had a higher SSC intensity, and these cells also could not differentiate normally. Our findings suggested that an SSC intensity analysis may be efficient method for evaluating individual iPS cells before their use in therapies.

    Mesenchymal stem cells (MSCs) are defined as cells that undergo sustained in vitro growth and are able of giving rise to multiple mesenchymal lineages. Although MSCs are already used in regenerative medicine, little is known about their in vivo behavior and developmental derivation. MSCs are a heterogeneous subset of stromal stem cells isolated from many adult tissues. Previous studies have reported that MSCs can differentiate into both mesodermal and neural lineages through a phenomenon referred to as "dedifferentiation" or "trans-differentiation". Limb mesenchymal cells reportedly originate from the lateral plate mesoderm. An additional origin of MSCs is the neural crest. Here, we prospectively identified paraxial mesoderm-derived MSCs in the bone marrow of adult transgenic mice encoding early mesoderm-specific Mesp1-Cre/Floxed-EGFP. We observed that a small but significant amount of Mesp1+ cells existed in adult bone marrow. Interestingly, the detected EGFP+ cells in the bone marrow were mostly present in the haematopoietic cells and EGFP+ MSCs differentiated into osteocytes, adipocytes, chondrocytes, neurons, glial cells, and myofibroblasts. No significant differences in the in vitro characteristics were observed between EGFP+ and EGFP- MSCs from Mesp1-Cre/Floxed-EGFP mice. Our results suggested that MSCs in adult bone marrow have a multi-developmental origin and that a portion of them are derived from Mesp1+ early paraxial mesoderm.

    近年、間葉系幹細胞(MSC)の免疫機能調節能力に注目が集まり、MSCの静脈投与は薬剤関連顎骨壊死(MRONJ)等の難治性炎症性疾患に対して免疫を制御する画期的な治療法として期待されている。しかし、静脈血に投与した細胞のほとんどは肺に捕捉されるため、副作用や患部に到達し難いという根本的な課題がある。本研究では、「リンパ行性薬剤送達法」に着目し、MRONJに対してリンパ節内に投与したMSCをリンパ行性に患部に送達させる治療アプローチを探索し、その作用機序を細胞遊走および免疫応答の観点から理解することを目的とする。初年度は、予備実験としてMRL/MpJmsSlc-lpr/lprマウスの大腿骨骨髄より分離培養したMSCを、全身のリンパ節が生まれつき腫脹しておりリンパ節に細胞の投与が容易なMXH51マウスの腸骨下リンパ節内および比較対象群の尾静脈内に投与する実験系を確立した。また、投与する細胞数がリンパ節組織におけるCD4、CD8および炎症性サイトカインの発現に及ぼす影響を検討し、至適投与細胞数を決定した。投与した腸骨下リンパ節と伝達先の下流にある固有腋窩リンパ節におけるこれら分子の遺伝子発現について検討した結果、下流のリンパ節においてより著明な免疫応答を認めた。また、肺の組織切片観察の結果、尾静脈内投与群では投与した細胞に起因するとみられる炎症性細胞浸潤を認めたが、リンパ節内投与群ではそのような所見を認めなかったことから、リンパ行性薬剤送達法は静脈投与よりも副作用の少ない細胞投与法である可能性が示唆された。今後、免疫応答の詳細と共に顎骨壊死(ONJ)発症モデルを用いた検討を行う予定である。

    Recently, organoid-on-a-chip technologies, which enable us to reproduce biological function of cells and tissues at the organ level in vitro, commands considerable attention. The aim of this study was to establish culture methods for the bone/cartilage/tooth organoids-on-a-chip using induced pluripotent stem (iPS) cell technology towards creating precision prosthodontics. We established induction method of iPS cells to bone organoid using micro-space culture wells. We also found a method to induce the bone/cartilage hybrid by applying a shaking culture. Furthermore, we established a step-wise culture method to induce iPS cells to enamelblasts. These results would contribute to the production of bone/cartilage/tooth organoids-on-a-chip in the future, and may lead to the basic technology of precision prosthetics that reproduces patient hard tissues in vitro.

    The objective of this study is to control tooth root by inhibiting HDAC3 of dental mesenchyme. Our MSC-spheroids which showed neural crest stem cell like phenotype highly expressed HDAC9, HDAC11 and down regulated ESCO2, AURKA, and AURKB by analyzing PCR array. Our experiments suggested that the epigenetic change of MSC-spheroids was related to the gene expression of cell proliferation and differentiation. In addition, we performed tooth organ germ method by using MSC-spheroid and fetal dental epithelium. We successfully generate tooth organ using our MSC-spheroids. The next step, we will use HDAC inhibitor to organ germ to make clear whether HDAC inhibitor can control tooth root length.

    This study was aimed to establish a tooth engineering protocol by self-organization of iPS cells. Transcriptional regulation system was applied to mouse iPS cells in 3D culture to control expression of a tooth development-related gene. As a result, iPS cell aggregates formed cystic structures, which express oral ectoderm marker molecules. A step-wise induction method was also established to guide mouse iPS cells to differentiate into dental epithelial cells. When mouse iPS cells were cultured in hydrogels with different stiffness, effects of the stiffness on expression of tooth development-related genes were not significant. These results would contribute to promote iPS cell-based tooth engineering/regeneration in future.

    Studies on human and animal models have demonstrated the complex molecular regulatory network between dental mesenchyme and epithelium governing tooth development. However, epigenetic regulation of tooth development has not been well investigated. The aim of this study was to elucidate the relationship between an epigenetic modifier and dental root development using Hdac3-CKOosx mice. We show that Hdac3 depletion in Osterix expressing dental pulp stem cells, odontoblasts, and cementocytes cause a progressive postnatal obstruction resulting in comparatively short roots and smaller root apices of the molar. We observed degeneration in the histological development of dentin and cementum structures. Dentin and cementum had shaky borders and disordered hematoxylin staining; in addition, the Hdac3-CKOosx had thin cementum compared to that in the wild-type mice. These findings show that Hdac3 is essential in dental mesenchymal cells and regulates the rate of root formation and development.

    胎生期の原腸陥入の時期における初期の中胚葉由来の細胞をトレース可能となったMesp1-cre/CAG-EGFPマウスの骨髄をフローサイトメーターにて解析した結果、Mesp1+,Mesp1-どちらの分画にもPDGFRα+/Sca-1+の間葉系幹細胞(MSCs)集団が存在していることが分かった。そしてどちらの分画からも分化誘導実験及び遺伝子発現解析から、脂肪・軟骨・骨へ分化するMSCsをクローナルに分離することが可能であった。以上より、中胚葉由来の細胞中に、MSCsの性質を有する細胞が存在していることが確認できた。またMesp1-cre/CAG-EGFPマウスの骨髄細胞を用いて、神経堤系細胞への分化能解析を行った結果、中胚葉由来であるはずのMesp1-分画の細胞は、神経堤細胞の分化条件下でMesp1-分画の細胞(神経堤由来幹細胞を含む)と同様に神経・グリア・平滑筋という神経堤系統への分化能を有しており、分化誘導前の状態で、神経堤幹細胞マーカーとして知られるP75,Snail,Sox9を発現していることが分かった。Mesp1陽性細胞は神経堤幹細胞マーカーとして知られるPOの発現とは発生の段階で重ならないことが分かっており、Mesp1陽性の中胚葉由来MSCsは、神経堤由来では無いにも関らず、神経堤系統への分化能を有していたこととなる。 これまでの研究で、MSCsの一部の供給源は神経堤幹細胞(NCSCs)であると言われていたが、我々の解析の結果、中胚葉由来の細胞中にも間葉系及び神経堤系という2種類の系列への細胞に分化する能力を有する細胞が存在していることが分かった。 いまだにMSCs及びNCSCsの生体内での局在や全ての起源が明らかとなった訳ではないが、我々の研究によりMSCsと定義される細胞の発生学的起源やin vivoでの局在、振る舞いが明らかになり、再生医療の細胞供給源をより安全で確実なものにできると期待している。
