Abstract
Tendon injuries often result in significant pain and disability and impose severe clinical and financial burdens on our society. Despite considerable achievements in the field of regenerative medicine in the past several decades, effective treatments remain a challenge due to the limited natural healing capacity of tendons caused by poor cell density and vascularization. The development of tissue engineering has provided more promising results in regenerating tendon-like tissues with compositional, structural and functional characteristics comparable to those of native tendon tissues. Tissue engineering is the discipline of regenerative medicine that aims to restore the physiological functions of tissues by using a combination of cells and materials, as well as suitable biochemical and physicochemical factors. In this review, following a discussion of tendon structure, injury and healing, we aim to elucidate the current strategies (biomaterials, scaffold fabrication techniques, cells, biological adjuncts, mechanical loading and bioreactors, and the role of macrophage polarization in tendon regeneration), challenges and future directions in the field of tendon tissue engineering.

Intravenous Administration of Human Amniotic Mesenchymal Stem Cells in the Subacute Phase of Cerebral Infarction in a Mouse Model Ameliorates Neurological Disturbance by Suppressing Blood Brain Barrier Disruption and Apoptosis via Immunomodulation.

Abstract
Neuro-inflammation plays a key role in the pathophysiology of brain infarction. Cell therapy offers a novel therapeutic option due to its effect on immunomodulatory effects. Amniotic stem cells, in particular, show promise owing to their low immunogenicity, tumorigenicity, and easy availability from amniotic membranes discarded following birth. We have successfully isolated and expanded human amniotic mesenchymal stem cells (hAMSCs). Herein, we evaluated the therapeutic effect of hAMSCs on neurological deficits after brain infarction as well as their immunomodulatory effects in a mouse model in order to understand their mechanisms of action. One day after permanent occlusion of the middle cerebral artery (MCAO), hAMSCs were intravenously administered. RT-qPCR for TNFα, iNOS, MMP2, and MMP9, immunofluorescence staining for iNOS and CD11b/c, and a TUNEL assay were performed 8 days following MCAO. An Evans Blue assay and behavioral tests were performed 2 days and several months following MCAO, respectively. The results suggest that the neurological deficits caused by cerebral infarction are improved in dose-dependent manner by the administration of hAMSCs. The mechanism appears to be through a reduction in disruption of the blood brain barrier and apoptosis in the peri-infarct region through the suppression of pro-inflammatory cytokines and the M2-to-M1 phenotype shift.

Abstract
Cholinergic efferent networks located from the medial septal nucleus to the hippocampus play a pivotal role in learning and memory outcomes by generating regular theta rhythms that enhance information retention. Hippocampal cholinergic neurostimulating peptide (HCNP), derived from the N-terminus of HCNP precursor protein (HCNP-pp), promotes the synthesis of acetylcholine in the medial septal nuclei. HCNP-pp deletion significantly reduced theta power in CA1 possibly due to lower levels of choline acetyltransferase-positive axons in CA1 stratum oriens, suggesting cholinergic disruptions in the septo-hippocampal system. This review also explores HCNP as a potent cholinergic regulator in the septo-hippocampal network while also examining the limitations of our understanding of the neurostimulating peptide.

Abstract
Stem cells including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs) and adult stem cells (ASCs) are able to repair/replace damaged or degenerative tissues and improve functional recovery in experimental model and clinical trials. However, there are still many limitations and unresolved problems regarding stem cell therapy in terms of ethical barriers, immune rejection, tumorigenicity, and cell sources. By reviewing recent literatures and our related works, human amnion-derived stem cells (hADSCs) including human amniotic mesenchymal stem cells (hAMSCs) and human amniotic epithelial stem cells (hAESCs) have shown considerable advantages over other stem cells. In this review, we first described the biological characteristics and advantages of hADSCs, especially for their high pluripotency and immunomodulatory effects. Then, we summarized the therapeutic applications and recent progresses of hADSCs in treating various diseases for preclinical research and clinical trials. In addition, the possible mechanisms and the challenges of hADSCs applications have been also discussed. Finally, we highlighted the properties of hADSCs as a promising source of stem cells for cell therapy and regenerative medicine and pointed out the perspectives for the directions of hADSCs applications clinically.

Abstract
OBJECTIVES Human amniotic epithelial cells have multipotent differentiation capacity and are considered as potential therapeutic cells for clinical use. This study represents the first published report on the evaluation of the safety and clinical feasibility of human amniotic epithelial cells for transplant into knee joints, serving as an initial step for subsequent therapeutic evaluations within arthritis clinics. MATERIALS AND METHODS Our experimental design was based on subjecting groups of rabbits as a recipient model for human amniotic epithelial cell transplant into knee joints. Twenty rabbits received 200 μL sterile 0.9% sodium chloride solution containing 1 × 10⁹ human amniotic epithelial cells/knee joint by intra-articular injection. Control groups received cell-free saline into knees, and some animals were not treated. After 10 days of xenotransplant, radiology scans and histologic sections of transplanted and nontrans planted knees were examined and compared. Immunohistochemistry staining was also applied to detect tumor necrosis factor-alpha and interleukin 17 (as inflammatory and immuno-rejection markers) in knee sections. RESULTS Similar to results shown in noninjected and saline-injected knees, all treated knees appeared normal, with no signs of acute immunorejection, no microbial colonization, no pain, no allergic reactions, no inflammation, and normal motion. Use of human amniotic epithelial cells appeared safe without risk of immunorejection or tumor formation in the transplanted knee joint. CONCLUSIONS Human amniotic epithelial cells can be safely transplanted into knee joints, encouraging a need for complementary research for further therapeutic evaluations of human amniotic epithelial cells for curing arthritis.

Abstract
Moyamoya disease (MMD) represents a rare steno-occlusive disorder affecting the terminal ends of the internal carotid artery and promoting the development of a poor, abnormal vascular network at the brain's base. Primarily affecting East Asian countries over Western populations, MMD can be further divided into symptomatic and asymptomatic subtypes. The current knowledge of the underlying mechanisms and potential management strategies for asymptomatic cases of MMD are largely lacking and thus warrant investigation to elucidate the pathology of this rare disorder. Here, we assess research examining the expression profile of circular RNAs (circRNAs) of neutrophil transcriptome in asymptomatic MMD patients. These findings conclude that 123 differentially expressed circRNAs significantly contributed to metabolism, angiogenesis, and immune response. The hypoxia-inducing factor-1α signaling pathway was also revealed to be crucial in angiogenesis. We also evaluate current therapeutic options demonstrating the potential for MMD patients, such as EC-IC bypass and ischemic pre- and post-conditioning. These approaches combined with recent findings on the circRNA expression profile suggest a crucial role of anti-inflammatory and angiogenic-related mechanisms underlying MMD. Investigating the role of circRNAs and neutrophils in the asymptomatic MMD subtype may provide insight into its elusive pathology and direct future approaches to combat the progression of this rare disease.

Abstract
BACKGROUND AIMS Human amniotic mesenchymal stromal cells (hAMSCs) are a potent and attractive stem cell source for use in regenerative medicine. However, the safe uses of therapeutic-grade MSCs are equally as important as the efficiency of MSCs. To provide efficient, clinic-compliant (safe for therapeutic use) MSCs, hAMSC lines that completely eliminate the use of animal products and have been characterized for carcinogenicity and biosafety are required. METHODS Here, we have efficiently generated 10 hAMSC lines under human umbilical cord blood serum (hUCS)-supplemented medium (xeno-free culture) and fetal bovine serum (FBS)-supplemented medium (standard culture) and investigated carcinogenicity and immunosuppressive properties in the resultant hAMSC lines. All hAMSC lines were examined for efficiency (growth kinetics, cryopreservation, telomere length, phenotypic characterization, differentiation potential), carcinogenicity (proto-oncogene and tumor suppressor gene and epigenomic stability) and safety (immunosuppressive properties). RESULTS Stem cell characteristics between the xeno-free hAMSC lines and the cell lines generated using the standard culture system showed no differences. Xeno-free hAMSC lines displayed normal growth proliferation potential, morphological, karyotypic, phenotypic differentiation properties and telomere lengths. Additionally, they retained normal immunosuppressive effects. As a marker of carcinogenicity and biosafety, proto-oncogenes expression levels showed no differences in xeno-free hAMSCs, and we detected no SNP mutations on hotspot codons of the P53 tumor suppressor gene and stable epigenomic imprinting in xeno-free hAMSC lines. CONCLUSIONS Xeno-free hAMSC lines retain essential stem cell characteristics, with a high degree of certainty for meeting biosafety and carcinogenicity standards for a xeno-free system supplemented with allogenic hUCS. The cell lines are suitable and valuable for therapeutic purposes.
