Lee HJ, Jeon M, Kim YH, Kim SO, Lee KE. Comparative gene expression analysis of stemness between periodontal ligament and umbilical cord tissues in humans. J Dent Sci 2023; 18:211-219. [PMID: 36643271 PMCID: PMC9831792 DOI: 10.1016/j.jds.2022.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 06/09/2022] [Indexed: 01/18/2023] Open
Abstract
Background/purpose Due to their regenerative potential, periodontal ligament (PDL) and umbilical cord (UBC) tissues are an attractive potential mesenchymal stem cells (MSCs) source. This study compared the expression patterns of genes related to stemness between fresh PDL and UBC tissues. Materials and methods PDL tissues were collected from 38 permanent premolars extracted for orthodontic purposes, and UBC tissues were obtained from three newborns. Each sample was immediately frozen to prevent RNA degradation. cDNA microarray analysis, quantitative real-time polymerase chain reaction (PCR), and immunohistochemical staining were performed. Gene expression patterns associated with dental stemness (DS) and induced pluripotent stemness (iPS) were compared between PDL and UBC tissues. Results In the cDNA microarray analyses, the expressions of most iPS genes were greater in the PDL than in the UBC. Meanwhile, the expressions of most DS genes were greater in the UBC than in the PDL. Quantitative real-time PCR analyses showed that the expression levels of matrix metallopeptidase 13 (MMP13), ADAM metallopeptidase domain 22 (ADAM22), vascular cell adhesion protein 1 (VCAM1), and kruppel-like factor 4 (KLF4) genes were greater in the PDL than in the UBC, while the expressions of melanoma cell adhesion molecule (MCAM) and activated leukocyte cell adhesion molecule (ALCAM) were greater in the UBC than in the PDL. Conclusion These results suggest that UBC and PDL tissues showed slightly different expression patterns of genes related to stemness, which warrants further investigation to use these tissues for future regeneration and implantation therapies.

Abstract
Background and Objectives Umbilical cord blood (UCB) donation is a behaviour promoted by many countries' health systems. However, UCB donation is not a widespread behaviour among expectant mothers, and little is known about the reasons that may lead to it. The aim of the present study was to analyse the contribution of Theory of Planned Behaviour (TPB) variables among both primiparous and multiparous women in predicting intention to donate UCB. Materials and Methods Three hundred seventy‐six expectant mothers completed questionnaires that captured sociodemographic data, parity, previous donation, attitudes, subjective norms, perceived behavioural control (PBC) and intention to donate UCB. Multigroup analysis structural equation modelling was conducted using Mplus (version 8.02). Results Multigroup path analyses showed that intentions were strongly predicted by subjective norms and moderately predicted by positive attitudes and PBC in both primiparous and multiparous women. TPB constructs explained 71% of the variance in intentions for both groups. Conclusions Future interventions to increase intention to donate among primiparous and multiparous women could primarily consider the influence of partner and significant others in determining positive intentions and secondarily target increasing positive attitudes and perceptions of control.

Abstract
The use of umbilical cord blood (UCB) holds promise for the treatment of a wide spectrum of diseases. However, information on UCB donation is not widespread or accurate among expectant women. The aim of this study is to evaluate pregnant women's knowledge of UCB donation, their main sources of information and their satisfaction with the knowledge possessed. Women (N = 375) in the last semester of pregnancy completed questionnaires evaluating sociodemographics, knowledge of UCB donation, past donation, sources of information, satisfaction with the information and the desire to have received more information. Women were aware of the possibility of donating UCB (97.5%) although, on average, they reported not having enough knowledge of donation possibilities, procedures to be followed and uses of UCB (2.51, on a 5-point scale). Considering knowledge satisfaction, 28% were not at all satisfied. Only 2.8% felt fully prepared and the great majority (75.2%) would have liked to have received more information. The main source of information was the Internet (51.2%). Gynecologists and midwives were indicated by only 24.4% and 18.6% of women, respectively. Age and education were significantly correlated with UCB knowledge. Chi-square tests evidenced that those who reported professional sources of information (gynecologists, obstetricians, prenatal courses) did not need additional information. Conversely, mothers who turned to other mothers for information were more likely to desire further information. Most mothers report the Internet as the main source of information. Providing accurate information through official sources may result in a more positive attitude toward donation.

Abstract
The purpose of regenerative medicine is to restore or enhance the normal function of human cells, tissues, and organs. From a clinical point of view, the use of stem cells is more advantageous than differentiated cells because they can be collected more easily and in larger quantities, their proliferation capacity is more pronounced, they are more resistant in cell culture, their aging is delayed, they are able to form a number of cell lines, and they are able to promote vascularization of tissue carriers. The therapeutic use of stem cells for disease modification, immunomodulation, or regenerative purposes are undoubtedly encouraging, but most studies are still in their early stages, and the clinical results reported are not clear with regard to therapeutic efficacy and potential side effects. Uniform regulation of the clinical application of stem cells is also indispensable for this highly customizable, minimally invasive, individualized therapeutic method to become a successful and safe treatment alternative in many different autoimmune and autoinflammatory disorders.

Abstract
Stem cells possess the extraordinary capacity of self-renewal and differentiation to various cell types, thus to form original tissues and organs. Stem cell heterogeneity including genetic and nongenetic mechanisms refers to biological differences amongst normal and stem cells originated within the same tissue. Cell differentiation hierarchy and stochasticity in gene expression and signaling pathways may result in phenotypic differences of stem cells. The maintenance of stemness and activation of differentiation potential are fundamentally orchestrated by microenvironmental stem cell niche-related cellular and humoral signals.

Abstract
Kidney is one of the most difficult organs for regeneration. Several attempts have been performed to regenerate renal tissue using stem cells, the results were not satisfactory. Urine is major product of kidney and contains cells from renal components. Moreover, urine-derived stem cells (USCs) can be easily obtained without any health risks throughout a patient's entire life. Here, we evaluated the utility of USCs for renal tissue regeneration. In this study, the ability of USCs to differentiate into renal lineage cells was compared with that of adipose tissue-derived stem cells (ADSCs) and amniotic fluid-derived stem cells (AFSCs), with respect to surface antigen expression, morphology, immunocytochemistry, renal lineage gene expression, secreted factors, immunomodulatory marker expression, in vivo safety, and renal differentiation potency. Undifferentiated USCs were positive for CD44 and CD73, negative for CD34 and CD45, and formed aggregates after 3 weeks of renal differentiation. Undifferentiated USCs showed high SSEA4 expression, while renal-differentiated cells expressed PAX2, WT1, and CADHERIN 6. In the stem/renal lineage-associated gene analysis, OCT4, SSEA4, and CD117 were significantly downregulated over time, while PAX2, LIM1, PDGFRA, E-CADHERIN, CD24, ACTB, AQP1, OCLN, and NPHS1 were gradually upregulated. In the in vivo safety evaluation, renal-differentiated USCs did not show abnormal histology. These findings demonstrated that USCs have a similar MSC potency, renal lineage-differentiation ability, immunomodulatory effects, and in vivo safety as ADSCs and AFSCs, and showed higher levels of growth factor secretion for paracrine effects. Therefore, urine and USCs can be one of good cell sources for kidney regeneration.

Abstract
Traumatic brain injury (TBI) is now characterized as a progressive, degenerative disease and continues to stand as a prevalent cause of death and disability. The pathophysiology of TBI is complex, with a variety of secondary cell death pathways occurring which may persist chronically following the initial cerebral insult. Current therapeutic options for TBI are minimal, with surgical intervention or rehabilitation therapy existing as the only viable treatments. Considering the success of stem-cell therapies in various other neurological diseases, their use has been proposed as a potential potent therapy for patients suffering TBI. Moreover, stem cells are highly amenable to adjunctive use with other therapies, providing an opportunity to overcome the inherent limitations of using a single therapeutic agent. Our research has verified this additive potential by demonstrating the efficacy of co-delivering human umbilical cord blood (hUCB) cells with granulocyte-colony stimulating factor (G-CSF) in a murine model of TBI, providing encouraging results which support the potential of this approach to treat patients suffering from TBI. These findings justify ongoing research toward uncovering the mechanisms which underlie the functional improvements exhibited by hUCB + G-CSF combination therapy, thereby facilitating its safe and effect transition into the clinic. This paper is a review article. Referred literature in this paper has been listed in the reference section. The datasets supporting the conclusions of this article are available online by searching various databases, including PubMed. Some original points in this article come from the laboratory practice in our research center and the authors’ experiences.

Abstract
Impaired wound healing is a severe clinical challenge and research into finding effective wound healing strategies is underway as there is no ideal treatment. Gelatinous material from the umbilical cord called Wharton's jelly is a valuable source of mesenchymal stem cells which have been shown to aid wound healing. While the cellular component of Wharton's jelly has been the subject of extensive research during the last few years, little is known about the de-cellularized jelly material of the umbilical cord. This is important as they are native niche of stem cells. We have isolated Wharton's jelly from umbilical cords and then fractionated acellular gelatinous Wharton's jelly (AGWJ). Here, we show for the first time that AGWJ enhances wound healing in vitro as well as in vivo for wounds in a murine model. In vivo staining of the wounds revealed a smaller wound length in the AGWJ treated wounds in comparison to control treatment by enhancing cell migration and differentiation. AGWJ significantly enhanced fibroblast cell migration in vitro. Aside from cell migration, AGWJ changed the cell morphology of fibroblasts to a more elongated phenotype, characteristic of myofibroblasts, confirmed by upregulation of alpha smooth muscle actin using immunoblotting. AGWJ treatment of wounds led to accelerated differentiation of cells into myofibroblasts, shortening the proliferation phase of wound healing. This data provides support for a novel wound healing remedy using AGWJ. AGWJ being native biological, cost effective and abundantly available globally, makes it a highly promising treatment option for wound dressing and skin regeneration.

Abstract
INTRODUCTION Due to their regenerative ability, stem cells are looked at as a promising tool for improving infertility treatments in women. As the main limiting factor in female fertility is represented by the decrease of ovarian reserve, the main goals of stem cell-based clinical platforms would be to obtain in vitro or in vivo neo-oogenesis. Refractory endometrial factor infertility also represents an obstacle for female reproduction for which stem cells might provide novel treatment strategies. Areas covered: A systematic search of the literature was performed on MEDLINE/PubMed database to identify relevant articles using stem-cell based clinical or research platforms in the field of female infertility. Expert opinion: In vitro oogenesis has not so far developed beyond the stage of oocyte-like cells whose normal progression to mature oocytes and ability to be fertilized was not proved. Extensive epigenetic programming of gamete precursors and the complex interactions between somatic and germ cells required for human oogenesis likely represent the main obstacles in stem-cell-based neo-oogenesis. Also resuming oogenesis in vivo in adulthood still appears a distant hypothesis, as there is still a lack of consensus about the existence and functionality of adult ovarian stem cells.

Abstract
Tissue engineering has emerged at the intersection of numerous disciplines to meet a global clinical need for technologies to promote the regeneration of tissues. Recently, many authors have focused their attention on mesenchymal stem/stromal cells (MSCs) for their capacity to differentiate into many cell lineages. The most widely studied cell types are bone marrow mesenchymal stem cells and adipose-derived stem cells (ASCs), which display similar results. Biomaterials, cells, and growth factors are needed to design a regenerative plastic surgery approach in the treatment of organ and tissue defects, but not all tissues are created equal. The aim of this article is to describe the advances in tissue engineering through the use of ASCs, platelet rich plasma, and biomaterials to enable regeneration of damaged complex tissue.

Abstract
Type 1 diabetes mellitus (T1DM) is a chronic disorder that results from autoimmune-mediated destruction of pancreatic islet β-cells. However, to date, no conventional intervention has successfully treated the disease. The optimal therapeutic method for T1DM should effectively control the autoimmunity, restore immune homeostasis, preserve residual β-cells, reverse β-cell destruction, and protect the regenerated insulin-producing cells against re-attack. Umbilical cord blood is rich in regulatory T (T(reg)) cells and multiple types of stem cells that exhibit immunomodulating potential and hold promise in their ability to restore peripheral tolerance towards pancreatic islet β-cells through remodeling of immune responses and suppression of autoreactive T cells. Recently, reinfusion of autologous umbilical cord blood or immune cells from cord blood has been proposed as a novel therapy for T1DM, with the advantages of no risk to the donors, minimal ethical concerns, a low incidence of graft-versus-host disease and easy accessibility. In this review, we revisit the role of autologous umbilical cord blood or immune cells from cord blood-based applications for the treatment of T1DM.

Abstract
To address the hypothesis that using a zirconia (ZrO2)/ β-tricalcium phosphate (β-TCP) composite might improve both the mechanical properties and cellular compatibility of the porous material, we fabricated ZrO2/β-TCP composite scaffolds with different ZrO2/β-TCP ratios, and evaluated their physical and mechanical characteristics, also the effect of three-dimensional (3D) culture (ZrO2/β-TCP scaffold) on the behavior of human endometrial stem cells. Results showed the porosity of a ZrO2/β-TCP scaffold can be adjusted from 65% to 84%, and the compressive strength of the scaffold increased from 4.95 to 6.25 MPa when the ZrO2 content increased from 30 to 50 wt%. The cell adhesion and proliferation in the ZrO2/β-TCP scaffold was greatly improved when ZrO2 decreased. Moreover, in vitro study showed that an osteoblasts-loaded ZrO2/β-TCP scaffold provided a suitable 3D environment for osteoblast survival and enhanced bone regeneration. We thus showed that a porous ZrO2/β-TCP composite scaffold has excellent mechanical properties, and cellular/tissue compatibility, and would be a promising substrate to achieve both bone reconstruction and regeneration needed during in vivo study for treatment of large bone defects.
