Abstract
Among all the adult stem cells, odontogenic stem cells inherit the characterization of neurogenic potential of their precursor ones-the cranial crest cells. Dental follicle cells (DFCs), one of the special kind of odontogenic stem cells, are raising interest in applying to regenerative medicine for they possess multi-differentiation potential, relatively free access and ethic-friendly characteristic. Parkinson's disease (PD), as one of the common neurodegenerative disorders, affects about 0.3% of the general population. Stem cell therapies are thought to be effective to treat it. Aiming at tackling ethical-concernings, confined sources and practically applicational limits, we made use of dopaminergic neurongenic differentiation potential of the DFCs and dedicated every effort to applying them as promising cell source for treating PD. Dental follicle cells were cultured from human dental follicle tissues collected from 12 to 18-year-old teenagers' completely impacted third molars. Our data demonstrated that hDFCs were expressing mesenchymal stem cell-associated surface markers, and possessed the ability of osteogenic, adipogenic and neurogenic differentiation in vitro. Additionally, hDFCs formed neuron-like cells in vitro and in vivo, as well as expressing dopaminergic-neuronogenic marker-TH. Moreover, hDFCs survived in the transplanted areas of the Parkinson's disease model of mouse over six weeks post-surgery, and the number of TH-positive DFCs in the DFCs-Grafted group surpassed its counterpart of the MPTP group with statistically significant difference. This study indicated that hDFCs might be a promising source of dopaminergic neurons for functional transplantation, and encouraged further detailed studies on the potential of hDFCs for treating PD.

Abstract
MicroRNAs (miRNAs) are endogenous short non-encoding RNAs which play a critical role on the output of the proteins, and influence multiple biological characteristics of the cells and physiological processes in the body. Mesenchymal stem/stromal cells (MSCs) are adult multipotent stem cells and characterized by self-renewal and multidifferentiation and have been widely used for disease treatment and regenerative medicine. Meanwhile, MSCs play a critical role in maintaining homeostasis in the body, and dysfunction of MSC differentiation leads to many diseases. The differentiation of MSCs is a complex physiological process and is the result of programmed expression of a series of genes. It has been extensively proven that the differentiation process or programmed gene expression is also regulated accurately by miRNAs. The differentiation of MSCs regulated by miRNAs is also a complex, interdependent, and dynamic process, and a full understanding of the role of miRNAs will provide clues on the appropriate upregulation or downregulation of corresponding miRNAs to mediate the differentiation efficiency. This review summarizes the roles and associated signaling pathways of miRNAs in adipogenesis, chondrogenesis, and osteogenesis of MSCs, which may provide new hints on MSCs or miRNAs as therapeutic strategies for regenerative medicine and biotherapy for related diseases.

Abstract
The autoimmune diseases are characterized by overactivation of immune cells, chronic inflammation, and immune response to self-antigens, leading to the damage and dysfunction of multiple organs. Patients still do not receive desired clinical outcomes while suffer from various adverse effects imparted by current therapies. The therapeutic strategies based on mesenchymal stromal cell (MSC) transplantation have become the promising approach for the treatment of autoimmune diseases due to the immunomodulation property of MSCs. MSCs derived from perinatal tissues are collectively known as perinatal MSCs (PMSCs), which can be obtained via painless procedures from donors with lower risk of being contaminated by viruses than those MSCs from adult tissue sources. Therefore, PMSCs may be the ideal cell source for the treatment of autoimmune diseases. This article summarizes recent progress and possible mechanisms of PMSCs in treating autoimmune diseases in animal experiments and clinical studies. This review also presents existing challenges and proposes solutions, which may provide new hints on PMSC transplantation as a therapeutic strategy for the treatment of autoimmune diseases.

Abstract
Mesenchymal stem cells (MSCs) have proven powerful potential for cell-based therapy both in regenerative medicine and disease treatment. Human umbilical cords and exfoliated deciduous teeth are the main sources of MSCs with no donor injury or ethical issues. The goal of this study was to investigate the differences in the biological characteristics of human umbilical cord mesenchymal stem cells (UCMSCs) and stem cells from human exfoliated deciduous teeth (SHEDs). UCMSCs and SHEDs were identified by flow cytometry. The proliferation, differentiation, migration, chemotaxis, paracrine, immunomodulatory, neurite growth-promoting capabilities, and acetaldehyde dehydrogenase (ALDH) activity were comparatively studied between these two MSCs in vitro. The results showed that both SHEDs and UCMSCs expressed cell surface markers characteristic of MSCs. Furthermore, SHEDs exhibited better capacity for proliferation, migration, promotion of neurite growth, and chondrogenic differentiation. Meanwhile, UCMSCs showed more outstanding adipogenic differentiation and chemotaxy. Additionally, there were no significant differences in osteogenic differentiation, immunomodulatory capacity, and the proportion of ALDHBright compartment. Our findings indicate that although both UCMSCs and SHEDs are mesenchymal stem cells and presented some similar biological characteristics, they also have differences in many aspects, which might be helpful for developing future clinical cellular therapies.

Abstract
Current treatment options for hypoxic-ischemic encephalopathy (HIE) are limited. Human umbilical cord mesenchymal stem cells (UC-MSCs) and cord blood mononuclear cells (CB-MNCs) offer great potential for the treatment of many neurological diseases. The aim of the present study was to identify which cell type is more effective for the treatment of HIE. PKH26-labeled UC-MSCs and CB-MNCs were transplanted into rats with hypoxia-ischemia (HI)-induced brain damage. Apoptotic cell numbers in the brain, as labeled by TUNEL, were assessed. Myelination and gliosis were investigated using myelin basic protein and glial fibrillary acidic protein immunohistochemistry, respectively. The Morris water maze was used to assess animal learning abilities. Our data show that transplantation of UC-MSCs or CB-MNCs after HI reduced astrogliosis, prevented neuronal loss in the striatum, and markedly improved functional brain outcomes after a 28-day recovery period. Moreover, treatment with CB-MNCs increased the proportion of mature oligodendrocytes and improved myelination in cortical areas. Both UC-MSCs and CB-MNCs may result in the recovery of neurological function in HI rats. Based on our data, UC-MSCs and UCB-MNCs may be particularly effective stem cell subsets for treatment of neonatal HIE.

Abstract
Mesenchymal stem cells (MSCs) are used as therapeutic tool for the treatment of immune diseases. The inflammatory environment also influences the characteristics of MSCs after transplantation. The aim of the study was to investigate the effects of pro-inflammatory cytokines on the characteristics of umbilical cord mesenchymal stem cells (UCMSCs). UCMSCs were exposed to pro-inflammatory cytokines in vitro for 3 and 7 days, and the biological properties were analyzed. The results showed that the proliferation ability was suppressed by interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β). The adipogenic capacity was inhibited in all conditioned medium, while the chondrogenic and osteogenic capacity was enhanced by TNF-α and IL-1β in vitro. Prostaglandin E2 (PGE2) was increased by IL-1β on the third day, and angiopoietin-1 (Ang-1) was inhibited appreciably by TNF-α on the seventh day. Interleukin-6 (IL-6) was increased by TNF-α and IL-1β, and hepatocyte growth factor (HGF) was inhibited by all inflammatory cytokines. IFN-γ secretion level from human peripheral mononuclear cells (hPBMCs) was lowered by UCMSCs which had been stimulated by TNF-α or IL-1β for 3 days. Moreover, IFN-γ and TNF-α secretion level was only inhibited by UCMSCs which had been by stimulated IFN-γ for 3 days but not 7 days. Our data demonstrated that different inflammatory cytokines and the duration of treatment had different effects on the properties of UCMSCs, which might be instructive for clinical pretreatment in cellular therapeutics.

Abstract
Stem cell implantation has been utilized for the repair of spinal cord injury; however, it shows unsatisfactory performance in repairing large scale lesion of an organ. We hypothesized that dental follicle cells (DFCs), which possess multipotential capability, could reconstruct spinal cord defect (SCD) in combination with biomaterials. In the present study, mesenchymal and neurogenic lineage characteristics of human DFCs (hDFCs) were identified. Aligned electrospun PCL/PLGA material (AEM) was fabricated and it would not lead to cytotoxic reaction; furthermore, hDFCs could stretch along the oriented fibers and proliferate efficiently on AEM. Subsequently, hDFCs seeded AEM was transplanted to restore the defect in rat spinal cord. Functional observation was performed but results showed no statistical significance. The following histologic analyses proved that AEM allowed nerve fibers to pass through, and implanted hDFCs could express oligodendrogenic lineage maker Olig2 in vivo which was able to contribute to remyelination. Therefore, we concluded that hDFCs can be a candidate resource in neural regeneration. Aligned electrospun fibers can support spinal cord structure and induce cell/tissue polarity. This strategy can be considered as alternative proposals for the SCD regeneration studies.

Abstract
Trauma or degenerative diseases of the central nervous system (CNS) cause the loss of neurons or glial cells. Stem cell transplantation has become a vital strategy for CNS regeneration. It is necessary to effectively induce nonneurogenic stem cells to differentiate into neurogenic cell lineages because of the limited source of neurogenic stem cells, relatively difficult cultivation, and ethical issues. Previous studies have found that dental stem cells can be used for transplantation therapy. The aim of this study was to explore a better inductive mode and time point for dental stem cells to differentiate into neural-like cells and evaluate a better candidate cell. In this study, dental follicle stem cells (DFSCs), dental papilla stem cells (DPSCs), and stem cells from apical papilla (SCAPs) were cultivated in five different modes. The proliferation ability, morphology, and expression of neural marker genes were analyzed. Results showed that DFSCs showed a higher proliferation potential. The proliferation was decreased after cultivation in chemical inductive medium as cultivation modes 3 and 5. The cells could present neural-like cell morphology after cultivation with human epidermal growth factor (EGF) and fibroblast growth factor-basic (bFGF) as cultivation modes 4 and 5. The vast majority of DFSCs gene expression levels in mode 4 on the third day was upregulated significantly. In conclusion, our data suggested that different dental stem cells exhibited different neural differentiation potentials. DFSCs might be the better candidate cell type. Furthermore, cultivation mode 4 and timing of the third day may promote differentiation into neurogenic cell lineages more effectively before transplantation to treat neurological diseases.

Abstract
OBJECTIVE In vitro tooth germ cultivation is an effective method to explore the mechanism of odontogenesis. The three-dimensional rotary cell culture system (RCCS) is typically used to culture simulated organs such as cartilage, skin, and bone. In this study, we established an in vitro tooth germ culture model using RCCS to investigate whether RCCS could provide an appropriate environment for tooth germ development in vitro. METHODS Mandibular first molar tooth germs from 1-day post-natal mice were cultured in RCCS for 3, 6, and 9 days. Tooth germ development was monitored via histology (hematoxylin & eosin staining), stereoscopic microscopy, and quantitative real-time PCR (RT-PCR). RESULTS Tooth germs cultured in RCCS maintained their typical spatial shape. Blood vessels were maintained on the dental follicle surface surrounding the crown. After cultivation, thick layers of dentin and enamel were secreted. Compared with tooth germs grown in jaw, the tooth germs grown in RCCS exhibited no significant difference in DMP1 or FGF10 expression at all time points. CONCLUSIONS Use of RCCS enhanced the development of tooth germs and allowed the tooth germs to maintain their spatial morphology. These results indicate that RCCS may be an effective culture system to investigate the mechanism of tooth development.
