Abstract
PROBLEM Accelerated placental aging is linked to abnormal fetal growth, preeclampsia (PE), and preterm birth (PTB). NANOG, a transcription factor, is known for its role in cellular reprogramming, self-renewal, and clonogenic growth. Its expression is regulated by Kruppel-like factor 4 (KLF4), which functions as both a transcriptional activator and repressor. This study evaluated the KLF4-NANOG pathway in placental samples from normal pregnancies (NP) as well as those with PE, fetal growth restriction (FGR), and PTB. METHOD OF STUDY Placental samples from NP pregnancies and those with PE, FGR, and PTB were analyzed for NANOG and KLF4 expression using western blotting and immunohistochemistry. RESULTS NANOG protein expression was significantly increased in placentas from PE, FGR, and PTB compared to NP (fold changes vs. NP: PE 2.48 ± 0.3, p = 0.002; FGR 1.64 ± 0.16, p = 0.03; PTB 6.03 ± 3.35, p = 0.01). Similarly, KLF4 protein expression was elevated in PE, FGR, and PTB placentas compared to NP (fold changes vs. NP: PE 5.78 ± 0.73, p = 0.001; FGR 2.61 ± 0.43, p = 0.02; PTB 11.42 ± 2.76, p = 0.0006). Immunohistochemistry revealed strong NANOG staining in the syncytiotrophoblast tissue of PE, FGR, and PTB samples, especially in extravillous trophoblasts, compared to NP placentas. CONCLUSIONS The elevated expression of NANOG and KLF4 in abnormal placental tissues suggests their potential role as markers of enhanced placental aging and dysfunction. These findings underscore the importance of the KLF4-NANOG pathway in the pathology of PE, FGR, and PTB, providing a basis for future research into therapeutic targets for these conditions.

Abstract
In equine regenerative medicine using bone marrow-derived mesenchymal stem/stromal cells (BM-MSC), the importance of the quality management of BM-MSC has been widely recognized. However, there is little information concerning the relationship between cellular senescence and the stemness in equine BM-MSC. In this study, we showed that stemness markers (NANOG, OCT4, SOX2 and telomerase reverse transcriptase) and colony forming unit-fibroblast apparently decreased accompanied with incidence of senescence-associated β-galactosidase-positive cells by repeated passage. Additionally, we suggested that down-regulation of cell proliferation in senescent BM-MSC was related to increased expression of cyclin-dependent kinase inhibitor 2B (CDKN2B). On the other hand, forced expression of NANOG into senescent BM-MSC brought upregulation of several stemness markers and downregulation of CKDN2B accompanied with restoration of proliferation potential and osteogenic ability. These results suggested that expression of NANOG was important for the maintenance of the stemness in equine BM-MSC.

Abstract
Peripheral Nerve Injuries (PNI) affect more than 20 million Americans and severely impact quality of life by causing long-term disability. The onset of PNI is characterized by nerve degeneration distal to the nerve injury resulting in long periods of skeletal muscle denervation. During this period, muscle fibers atrophy and frequently become incapable of "accepting" innervation because of the slow speed of axon regeneration post injury. We hypothesize that reprogramming the skeletal muscle to an embryonic-like state may preserve its reinnervation capability following PNI. To this end, we generated a mouse model in which NANOG, a pluripotency-associated transcription factor can be expressed locally upon delivery of doxycycline (Dox) in a polymeric vehicle. NANOG expression in the muscle upregulated the percentage of Pax7+ nuclei and expression of eMYHC along with other genes that are involved in muscle development. In a sciatic nerve transection model, NANOG expression led to upregulation of key genes associated with myogenesis, neurogenesis and neuromuscular junction (NMJ) formation, and downregulation of key muscle atrophy genes. Further, NANOG mice demonstrated extensive overlap between synaptic vesicles and NMJ acetylcholine receptors (AChRs) indicating restored innervation. Indeed, NANOG mice showed greater improvement in motor function as compared to wild-type (WT) animals, as evidenced by improved toe-spread reflex, EMG responses and isometric force production. In conclusion, we demonstrate that reprogramming the muscle can be an effective strategy to improve reinnervation and functional outcomes after PNI.

Abstract
Undoubtedly, mesenchymal stem cells (MSCs) are the most common cell therapy candidates in clinical research and therapy. They not only exert considerable therapeutic effects to alleviate inflammation and promote regeneration, but also show low-immunogenicity properties, which ensure their safety following allogeneic transplantation. Thanks to the necessity of providing a sufficient number of MSCs to achieve clinically efficient outcomes, prolonged in vitro cultivation is indisputable. However, either following long-term in vitro expansion or aging in elderly individuals, MSCs face cellular senescence. Senescent MSCs undergo an impairment in their function and therapeutic capacities and secrete degenerative factors which negatively affect young MSCs. To this end, designing novel investigations to further elucidate cellular senescence and to pave the way toward finding new strategies to reverse senescence is highly demanded. In this review, we will concisely discuss current progress on the detailed mechanisms of MSC senescence and various inflicted changes following aging in MSC. We will also shed light on the examined strategies underlying monitoring and reversing senescence in MSCs to bypass the comprised therapeutic efficacy of the senescent MSCs.

Abstract
We investigate the age-related metabolic changes that occur in aged and rejuvenated myoblasts using in vitro and in vivo models of aging. Metabolic and signaling experiments reveal that human senescent myoblasts and myoblasts from a mouse model of premature aging suffer from impaired glycolysis, insulin resistance, and generate Adenosine triphosphate by catabolizing methionine via a methionine adenosyl-transferase 2A-dependant mechanism, producing significant levels of ammonium that may further contribute to cellular senescence. Expression of the pluripotency factor NANOG downregulates methionine adenosyltransferase 2 A, decreases ammonium, restores insulin sensitivity, increases glucose uptake, and enhances muscle regeneration post-injury. Similarly, selective inhibition of methionine adenosyltransferase 2 A activates Akt2 signaling, repairs pyruvate kinase, restores glycolysis, and enhances regeneration, which leads to significant enhancement of muscle strength in a mouse model of premature aging. Collectively, our investigation indicates that inhibiting methionine metabolism may restore age-associated impairments with significant gain in muscle function.

Abstract
Mitochondrial dysfunction, a hallmark of aging, has been associated with the onset of aging phenotypes and age-related diseases. Here, we report that impaired mitochondrial function is associated with increased glutamine catabolism in senescent human mesenchymal stem cells (MSCs) and myofibroblasts derived from patients suffering from Hutchinson-Gilford progeria syndrome. Increased glutaminase (GLS1) activity accompanied by loss of urea transporter SLC14A1 induces urea accumulation, mitochondrial dysfunction, and DNA damage. Conversely, blocking GLS1 activity restores mitochondrial function and leads to amelioration of aging hallmarks. Interestingly, GLS1 expression is regulated through the JNK pathway, as demonstrated by chemical and genetic inhibition. In agreement with our in vitro findings, tissues isolated from aged or progeria mice display increased urea accumulation and GLS1 activity, concomitant with declined mitochondrial function. Inhibition of glutaminolysis in progeria mice improves mitochondrial respiratory chain activity, suggesting that targeting glutaminolysis may be a promising strategy for restoring age-associated loss of mitochondrial function.

Abstract
Aging remains a primary risk factor for a host of diseases, including leading causes of death. Aging and associated diseases are inherently multifactorial, with numerous contributing factors and phenotypes at the molecular, cellular, tissue, and organismal scales. Despite the complexity of aging phenomena, models currently used in aging research possess limitations. Frequently used in vivo models often have important physiological differences, age at different rates, or are genetically engineered to match late disease phenotypes rather than early causes. Conversely, routinely used in vitro models lack the complex tissue-scale and systemic cues that are disrupted in aging. To fill in gaps between in vivo and traditional in vitro models, researchers have increasingly been turning to organotypic models, which provide increased physiological relevance with the accessibility and control of in vitro context. While powerful tools, the development of these models is a field of its own, and many aging researchers may be unaware of recent progress in organotypic models, or hesitant to include these models in their own work. In this review, we describe recent progress in tissue engineering applied to organotypic models, highlighting examples explicitly linked to aging and associated disease, as well as examples of models that are relevant to aging. We specifically highlight progress made in skin, gut, and skeletal muscle, and describe how recently demonstrated models have been used for aging studies or similar phenotypes. Throughout, this review emphasizes the accessibility of these models and aims to provide a resource for researchers seeking to leverage these powerful tools.

Abstract
Cell-generated forces play a foundational role in tissue dynamics and homeostasis and are critically important in several biological processes, including cell migration, wound healing, morphogenesis, and cancer metastasis. Quantifying such forces in vivo is technically challenging and requires novel strategies that capture mechanical information across molecular, cellular, and tissue length scales, while allowing these studies to be performed in physiologically realistic biological models. Advanced biomaterials can be designed to non-destructively measure these stresses in vitro, and here, we review mechanical characterizations and force-sensing biomaterial-based technologies to provide insight into the mechanical nature of tissue processes. We specifically and uniquely focus on the use of these techniques to identify characteristics of cell and tissue "tensegrity:" the hierarchical and modular interplay between tension and compression that provide biological tissues with remarkable mechanical properties and behaviors. Based on these observed patterns, we highlight and discuss the emerging role of tensegrity at multiple length scales in tissue dynamics from homeostasis, to morphogenesis, to pathological dysfunction.

Abstract
Senescence of myogenic progenitors impedes skeletal muscle regeneration. Here, we show that overexpression of the transcription factor NANOG in senescent myoblasts can overcome the effects of cellular senescence and confer a youthful phenotype to senescent cells. NANOG ameliorated primary hallmarks of cellular senescence including genomic instability, loss of proteostasis, and mitochondrial dysfunction. The rejuvenating effects of NANOG included restoration of DNA damage response via up-regulation of DNA repair proteins, recovery of heterochromatin marks via up-regulation of histones, and reactivation of autophagy and mitochondrial energetics via up-regulation of AMP-activated protein kinase (AMPK). Expression of NANOG in the skeletal muscle of a mouse model of premature aging restored the number of myogenic progenitors and induced formation of eMyHC+ myofibers. This work demonstrates the feasibility of reversing the effects of cellular senescence in vitro and in vivo, with no need for reprogramming to the pluripotent state.

Fast photocurable thiol-ene elastomers with tunable biodegradability, mechanical and surface properties enhance myoblast differentiation and contractile function. Bioact Mater 2021; 6:2120-2133.

Abstract
Biodegradable elastomers are important emerging biomaterials for biomedical applications, particularly in the area of soft-tissue engineering in which scaffolds need to match the physicochemical properties of native tissues. Here, we report novel fast photocurable elastomers with readily tunable mechanical properties, surface wettability, and degradability. These elastomers are prepared by a 5-min UV-irradiation of thiol-ene reaction systems of glycerol tripentenoate (GTP; a triene) or the combination of GTP and 4-pentenyl 4-pentenoate (PP; a diene) with a carefully chosen series of di- or tri-thiols. In the subsequent application study, these elastomers were found to be capable of overcoming delamination of myotubes, a technical bottleneck limiting the in vitro growth of mature functional myofibers. The glycerol-based elastomers supported the proliferation of mouse and human myoblasts, as well as myogenic differentiation into contractile myotubes. More notably, while beating mouse myotubes detached from conventional tissue culture plates, they remain adherent on the elastomer surface. The results suggest that these elastomers as novel biomaterials may provide a promising platform for engineering functional soft tissues with potential applications in regenerative medicine or pharmacological testing.

Abstract
Mesenchymal stem/stromal cells (MSCs) have various properties that make them promising candidates for stem cell-based therapies in clinical settings. These include self-renewal, multilineage differentiation, and immunoregulation. However, recent studies have confirmed that aging is a vital factor that limits their function and therapeutic properties as standardized clinical products. Understanding the features of senescence and exploration of cell rejuvenation methods are necessary to develop effective strategies that can overcome the shortage and instability of MSCs. This review will summarize the current knowledge on characteristics and functional changes of aged MSCs. Additionally, it will highlight cell rejuvenation strategies such as molecular regulation, non-coding RNA modifications, and microenvironment controls that may enhance the therapeutic potential of MSCs in clinical settings.

Abstract
With age, adult skeletal muscle (SkM) is known to decrease in muscle mass, strength, and functional capacity, a state known as sarcopenia. Here we developed an in vitro three-dimensional (3D) bioengineered senescent SkM tissue using primary human myoblasts. These tissues exhibited the characteristics of atrophied muscle, including expression of senescent genes, decreased number of satellite cells, reduced number and size of myofibers, and compromised metabolism and calcium flux. As a result, senescent SkM tissues showed impaired ability to generate force in response to electrical stimulation compared with young tissues. Furthermore, in contrast to young SkM tissues, senescent tissues failed to regenerate in response to injury, possibly as a result of persistent apoptosis and failure to initiate a proliferation program. Our findings suggest that 3D senescent SkM may provide a powerful model for studying aging and a platform for drug testing and discovery of therapeutic compounds to improve the function of sarcopenic muscle. Impact statement Skeletal muscle (SkM) plays important physiological roles and has significant regenerative capacity. However, aged SkM lose their functionality and regeneration ability. In this article, we present a senescent human bioengineering SkM tissue model that can be used to investigate senescence, metabolic or genetic diseases that inflict SkM, and to test various strategies including novel small molecules that restore muscle function and promote regeneration. One key limitation of two-dimensional cell culture system is the detachment of contractile myotubes from the surface over time, thereby limiting the evaluation of myogenic function. Here we use primary human myoblasts, which exhibit all major hallmarks of aging to mimic the organization and function of native muscle. Using this system, we were able to measure the contractile function, calcium transients, and regeneration capacity of SkM tissues. We also evaluated the response of senescent SkM tissues to injury and their ability to regenerate and recover, compared with "young" tissues. Our results suggest that three-dimensional constructs enable organization of contractile units including myosin and actin filaments, thereby providing a powerful platform for the quantitative assessment of muscle myotubes in response to injury, genetic or metabolic disorders, or pharmacological testing.

Abstract
Stem cells derived from elderly donors or harvested by repeated subculture exhibit a marked decrease in proliferative capacity and multipotency, which not only compromises their therapeutic potential but also raises safety concerns for regenerative medicine. NANOG-a well-known core transcription factor-plays an important role in maintaining the self-renewal and pluripotency of stem cells. Unfortunately, the mechanism that NANOG delays mesenchymal stem cell (MSC) senescence is not well-known until now. In our study, we showed that both ectopic NANOG expression and PBX1 overexpression (i) significantly upregulated phosphorylated AKT (p-AKT) and PARP1; (ii) promoted cell proliferation, cell cycle progression, and osteogenesis; (iii) reduced the number of senescence-associated-β-galactosidase- (SA-β-gal-) positive cells; and (iv) downregulated the expression of p16, p53, and p21. Western blotting and dual-luciferase activity assays showed that ectopic NANOG expression significantly upregulated PBX1 expression and increased PBX1 promoter activity. In contrast, PBX1 knockdown by RNA interference in hair follicle- (HF-) derived MSCs that were ectopically expressing NANOG resulted in the significant downregulation of p-AKT and the upregulation of p16 and p21. Moreover, blocking AKT with the PI3K/AKT inhibitor LY294002 or knocking down AKT via RNA interference significantly decreased PBX1 expression, while increasing p16 and p21 expression and the number of SA-β-gal-positive cells. In conclusion, our findings show that NANOG delays HF-MSC senescence by upregulating PBX1 and activating AKT signaling and that a feedback loop likely exists between PBX1 and AKT signaling.

Abstract
Collagen type III (COL3) is one of the 3 major collagens in the body, and loss of expression or mutations in the COL3 gene have been associated with the onset of vascular diseases such the Ehlers-Danlos syndrome. Previous work reported a significant reduction of COL3 in tissues such as skin and vessels with aging. In agreement, we found that COL3 was significantly reduced in senescent human mesenchymal stem cells and myofibroblasts derived from patients with Hutchinson-Gilford progeria syndrome, a premature aging syndrome. Most notably, we discovered that ectopic expression of the embryonic transcription factor Nanog homeobox (NANOG) restored COL3 expression by restoring the activity of the TGF-β pathway that was impaired in senescent cells. RNA sequencing analysis showed that genes associated with the activation of the TGF-β pathway were up-regulated, whereas negative regulators of the pathway were down-regulated upon NANOG expression. Chromatin immunoprecipitation sequencing and immunoprecipitation experiments revealed that NANOG bound to the mothers against decapentaplegic (SMAD)2 and SMAD3 promoters, in agreement with increased expression and phosphorylation levels of both proteins. Using chemical inhibition, short hairpin RNA knockdown, and gain of function approaches, we established that both SMAD2 and SMAD3 were necessary to mediate the effects of NANOG, but SMAD3 overexpression was also sufficient for COL3 production. In summary, NANOG restored production of COL3, which was impaired by cellular aging, suggesting novel strategies to restore the impaired extracellular matrix production and biomechanical function of aged tissues, with potential implications for regenerative medicine and anti-aging treatments.-Rong, N., Mistriotis, P., Wang, X., Tseropoulos, G., Rajabian, N., Zhang, Y., Wang, J., Liu, S., Andreadis, S.

Abstract
Adult skeletal muscle regeneration relies on the activity of satellite cells residing in the skeletal muscle niche. However, systemic and intrinsic factors decrease the myogenic differentiation potential of satellite cells thereby impairing muscle regeneration. Here we present data showing that late passage C2C12 myoblasts exhibited significantly impaired myogenic differentiation potential that was accompanied by impaired expression of myogenic regulatory factors (Myf5, MyoD, Myogenin, and MRF4) and members of myocyte enhancer factor 2 family. Notably, ectopic expression of NANOG preserved the morphology and restored the myogenic differentiation capacity of late passage myoblasts, possibly by restoring the expression level of these myogenic factors. Muscle regeneration was effective in 2D cultures and in 3D skeletal microtissues mimicking the skeletal muscle niche. The presence of NANOG was required for at least 15days to reverse the impaired differentiation potential of myoblasts. However, it was critical to remove NANOG during the process of maturation, as it inhibited myotube formation. Finally, myoblasts that were primed by NANOG maintained their differentiation capacity for 20days after NANOG withdrawal, suggesting potential epigenetic changes. In conclusion, these results shed light on the potential of NANOG to restore the myogenic differentiation potential of myoblasts, which is impaired after multiple rounds of cellular division, and to reverse the loss of muscle regeneration.

Abstract
Ischemic heart diseases are a serious health problem worldwide. The transplantation of mesenchymal stem cells (MSCs) has been investigated in numerous clinical trials on various other diseases due to the self-renewal capacity of these cells and their potential to differentiate into a variety of cell types. The presence of excess reactive oxygen species in injured myocardium causes cardiac dysfunction and leads to inefficient repair of the heart. The poor outcomes of stem cell transplantation have been suggested to result from residual oxidative damage affecting the transplanted cells. The aim of the present study was to compare the effects of hydrogen peroxide (H2O2) on Wharton's jelly-derived MSCs (WJ-MSCs) and bone marrow-derived MSCs (BM-MSCs) in vitro, in order to provide information useful for the future selection of MSC types for cardiac differentiation and transplantation. H2O2 at concentrations of 200, 500 and 1,000 µM was applied to WJ-MSCs and BM-MSCs under cardiogenic differentiation conditions. The morphology of MSCs treated with H2O2 was similar to that of untreated cells, whereas the cell density decreased in direct association with the dose of H2O2. Cardiac differentiation markers were then evaluated by immunofluorescence analysis of GATA4 and cardiac troponin T (cTnT). The fluorescence intensity levels of the two markers were identified to be diminished by increasing doses of H2O2 from 500 to 1,000 µM. The expression levels of homeobox protein Nkx2.5, cTnT and cardiac α-actin were also examined, and were identified to be low in the WJ-MSCs treated with 1,000 µM H2O2, which was similar to the findings observed in BM-MSCs. These results suggested that oxidative stress affects cardiomyocyte differentiation via the downregulation of cardiac genes and cardiac proteins. Furthermore, it should be noted that there was a marked difference in the effect depending on the source of MSCs. This evidence provided supportive information for the use of stem cells in transplantation.

Abstract
Aging is the main risk factor contributing to vascular dysfunction and the progression of vascular diseases. In this review, we discuss the causes and mechanisms of vascular aging at the tissue and cellular level. We focus on Endothelial Cell (EC) and Smooth Muscle Cell (SMC) aging due to their critical role in mediating the defective vascular phenotype. We elaborate on two categories that contribute to cellular dysfunction: cell extrinsic and intrinsic factors. Extrinsic factors reflect systemic or environmental changes which alter EC and SMC homeostasis compromising vascular function. Intrinsic factors induce EC and SMC transformation resulting in cellular senescence. Replenishing or rejuvenating the aged/dysfunctional vascular cells is critical to the effective repair of the vasculature. As such, this review also elaborates on recent findings which indicate that stem cell and gene therapies may restore the impaired vascular cell function, reverse vascular aging, and prolong lifespan.
