Stem cell research and therapy are progressing these days dramatically. Stem cell therapy holds enormous treatment potential for many diseases which currently have no or limited therapeutic options. Unfortunately, this potential also comes with side-effects. In this review, the positive and negative effects of regulation of stem cells will be explained. Stem cells are undifferentiated cells which able to develop into many different cells of types in the body during early life and growth. There are five types of stem cells: embryonic stem cells, induced pluripotent stem cells, somatic stem cells, fetal stem cells and mesenchymal stem cells. Stem cell transplantation is one form of stem cell therapy, it comes with different techniques sourced, and those are autologous and allogeneic transplantation stem cells. In an autologous transplant, a patients blood-forming stem cells are collected, meanwhile, in an allogeneic transplant, target cells are replaced with new stem cells obtained from a donor or donated umbilical cord blood. Its abilities to maintain the phenotype, self-renewing and differentiate itself into specialized cells, give rise to stem cell as an innovation for the treatment of various diseases. In the clinical setting, stem cells are being explored for different conditions, such as in tissue repair and regeneration and autoimmune diseases therapy. But along with its benefit, stem cell therapy also holds some harm. It is known that the treatment using stem cell for curing and rehabilitation has the risk of tumor formation.Keywords:Â stem cell, therapy, transplantation, tumorigenic, mesenchymal stem cell, allogeneic

BACKGROUND: An organism’s lifespan is inevitably accompanied by the aging process, which involves functional decline, a steady increase of a plethora of chronic diseases, and ultimately death. Thus, it has been an ongoing dream of mankind to improve healthspan and extend life.CONTENT: There are only a few proposed aging interventions: caloric restriction, exercise, and the use of low-molecular-weight compounds, including spermidine, metformin, resveratrol, and rapamycin. Resveratrol, a constituent of red wine, has long been suspected to have cardioprotective effects. Interest in this compound has been renewed in recent years, first from its identification as a chemopreventive agent for skin cancer, and subsequently from reports that it activates sirtuin deacetylases and extends the lifespans of lower organisms. Resveratrol have been shown to prevent and reduce the severity of age-related diseases such as atherosclerosis, stroke, myocardial infarct, diabetes, neurodegenerative diseases, osteoarthritis, tumors and metabolic syndrome, along with their ability to extend lifespan.SUMMARY: The purpose of aging research is the identification of interventions that may avoid or ameliorate the ravages of time. In other words, the quest is for healthy aging, where improved longevity is coupled to a corresponding healthspan extension. It is only by extending the healthy human lifespan that we will truly meet the premise of the Roman poet Cicero: “No one is so old as to think that he may not live a year.”KEYWORDS: aging, caloric restriction, mimetic, healthspan, sirtuin activator

BACKGROUND: Cancer is a disease of genomic instability, evasion of immune cells, and adaptation of the tumor cells to the changing environment. Genetic heterogeneity caused by tumors and tumor microenvironmental factors forms the basis of aggressive behavior of some cancer cell populations.CONTENT: Cancers arise in self-renewing cell populations and that the resulting cancers, like their normal organ counterparts, are composed of hierarchically organized cell populations. Self â€“ renewing â€œcancer stem cellsâ€ (CSC) maintain tumor growth and generate the diverse populations constituting the tumor bulk. CSCs in multiple tumor types have been demonstrated to be relatively resistant to radiation and chemotherapy. The clinical relevance of these studies has been supported by neoadjuvant breast cancer trials that demonstrated increases in the proportions of CSCs after therapy. The CSC hypothesis has tremendously important clinical implications.SUMMARY: In summary, a large and accumulating body of evidence supports the CSC hypothesis, which has important implications for cancer prevention and therapy. The ultimate test of this hypothesis will require clinical trials demonstrating that targeting of these pathways reduces cancer incidence and improves outcomes for patients with cancer.KEYWORDS: Somatic mutation, tumor heterogeneity, metastasis, epithelial-mesenchymal transition, CSC niche

One of the most serious side effects of diabetes is diabetic foot ulceration (DFU). It is a severe and extremely morbid illness that has been linked to higher mortality on its own. The development of effective wound therapeutics in the future may be influenced by our current and developing understanding of wound pathophysiology. By reestablishing cellular functioning, small extracellular vesicles (sEVs), a crucial medium for intercellular communications, exhibit encouraging therapeutic potential in the treatment of DFU. Mesenchymal stem cell (MSC) derived exosomes and engineered extracellular vesicles (EVs) have the potential to aid in the healing of wounds. Along with encouraging the growth and stimulation of endothelial cells, keratinocytes, and fibroblasts, they also have immunomodulatory and anti-inflammatory properties. They help prevent damaged cells from dying, revitalize senescent cells, and boost angiogenesis. MSC-EVs can be a safe, effective and ethical therapy for DFU by increasing M2 macrophages polarization, improving the proliferation, reducing scar, and improving angiogenesis.KEYWORDS: mesenchymal stem cell, extracellular vesicle, diabetic wound, wound healing

Diabetes mellitus (DM) is a chronic endocrine and metabolic disease indicated by the presence of hyperglycemia. It has been known that hyperglycemia and oxidative stress are the main culprit of all DM complications, including macrovascular complications. As a byproduct of lipid, protein, and carbohydrate metabolism, methylglyoxal (MGO) is a highly reactive substance which plays a positive signaling role in helping cells regain redox balance under oxidative stress circumstances. DM-related problems lead to an excess of mitochondrial superoxide in the heart and big and small vascular endothelial cells. Elevated intracellular reactive oxygen species induce impaired angiogenesis in reaction to ischemia, trigger several proinflammatory pathways, and result in enduring epigenetic modifications that propel the continuous expression of proinflammatory genes even after glucose levels return to normal. Over time, the significance of the extremely quick advanced glycation end-products (AGE) production caused by the extremely reactive MGO has been clarified. It is now evident that MGO causes vascular tissue to react maladaptively. Glyoxalase 1 (GLO1) is the primary enzyme in an organism's enzymatic glyoxalase defense mechanism, which converts MGO to D-lactate in order to counteract the harmful effects of MGO. Understanding the role of the MGO–GLO1 pathway in the etiology of vascular disease in diabetes has advanced significantly. Therefore, it can be summarized that vascular damage are linked to diabetes. The AGE precursor MGO are important in determining the connection between diabetes and vascular damage. MGO and AGEs play a role in several phases of the development of diabetes complications. MGO and AGEs may be useful therapeutic targets for diabetes's macrovascular problems.KEYWORDS: hyperglycemia, AGE, methylglyoxal, glyoxalase, D-lactate, gluthatione, oxidative stress

BACKGROUND: World Health Organization has reported four million people die every year due to obesity comorbidity, and the prevalence of obesity is keep increasing, especially after COVID-19. Obesity has been defined as a chronic disease involving adipose tissue dysfunction which leads to metabolic diseases and psychosocial consequences. The review article will highlight some recent researches regarding the new conceptual framework that integrates both metabolic drives, as well as to summarize the numerous discussions about the current understanding of hypothalamic control of food intake and energy homeostasis.CONTENT: Obesity apparently is not simply regulated only by food and exercise. Hypothalamus takes part in controlling energy intake and expenditure via appetite regulation. Hedonic control in cortical and subcortical brain areas process cognitive, reward, information, and executive function. Managing metabolic adaptation, browning the white adipose tissue, and preserving lean mass can be another strategy to safely manage obesity.SUMMARY: Obesity need to be managed in a multimodal strategy including neurophysiology and physiology approach, together with environment support. Thus, a weight regain can be prevented. Commitment from both scientific and regulation point of view can shed a light to eradicate obesity.KEYWORDS: adipocyte, appetite, nutrition, obesity, physical activity, reward, satiety

BACKGROUND: Fibronectin type III domain-containing protein 5 (FNDC5), or also known as irisin, has been identified for two decades but almost completely disregarded for 10 years. It is present in skeletal muscle, heart, and brain, and in reaction to exercise can transform white adipose tissue into brown. Since then, irisin has gained a lot of attention for its potencies in treating metabolic disorders. In this review article, the potential future of irisin especially on metabolism and aging process will be discussed.CONTENT: Sedentary lifestyle is acknowledged as risk factor for type 2 diabetes mellitus, obesity, immune system issues, asthma, and neurological or heart illness. Irisin is secreted by muscle cells when exercising, produced after the proteolytic cleavage of FNDC5 protein. Irisin has positive impacts on maintaining physiological balance including reducing inflammation, keeping the bone homeostasis, as well as influencing metabolic processes and the neurological system function. Due to these many and advantageous characteristics, irisin could be a possible choice for preventing and managing disorders associated with modern society, and finding the agents to increase irisin can be beneficial.SUMMARY: Irisin offers a fresh potential basis for kinesitherapy and shows promise as a therapeutic target due to its various biological activities. Irisin pathway can be activated through dietary changes, the use of natural substances and drugs and can interact with this signalling pathway which involved peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) and uncoupling protein mRNA 1 (UCP1) to resolve obesity and its metabolic comorbidities.KEYWORDS: irisin, FNDC5, exercise, inflammation, obesity, nervous system

BACKGROUND: Age contributes to body composition alteration, rises a common disorder in elderly known as sarcopenic obesity (SO), which is characterized by the combination of obesity (excess fat mass) and sarcopenia (reduced skeletal muscle mass) clinical form and function.CONTENT: The primary cause of SO is insulin resistance. Glucose transporter 4 (GLUT4) dysfunction results in impaired fatty acids oxidation. Decreased muscle mass results in lower mitochondria number and volume. Both will increase oxidative stress. Together with altered myokines in SO, oxidative stress was promoted and lead to higher M1 macrophages and failure in autophagy. The pro-inflammatory condition and dysbiosis links SO to a variety of cardiometabolic conditions, including non-alcoholic fatty liver disease, type 2 diabetes, and cardiovascular disease. The mortality, comorbidities, cardiometabolic diseases, and disability or impairment of SO is higher compare to obesity or sarcopenia alone. Some treatments have been developed for SO including adequate dietary intake, vitamin D and antioxidant supplementation, and exercises.SUMMARY: SO is more prevalent among the elderly and has a significant negative impact on their quality of life. Therefore, maintaining muscle mass and strength as well as preventing obesity should be the key goals of initiatives to support healthy aging.KEYWORDS: aging, body composition, obesity, sarcopenia, skeletal muscle, metabolic syndrome

BACKGROUND: Burn injury induced increased risk of venous thromboembolism (VTE) due to hypercoagulability, immobilization, and endothelial injury. Despite this risk, VTE in burn patients often remains clinically undetected. Although D-dimer is widely used as a VTE marker, its utility in burn patients is inconsistent, particularly in the early post-burn period. Therefore, this study was conducted to evaluate the correlation between D-dimer levels and factors related to VTE, including hematologic, coagulation, immunologic, organ function parameters, and burn characteristics.METHODS: An analytical observational study was conducted involving adult patients with acute burn injuries enrolled in Dr. Soetomo General Hospital from March to June 2025. Demographic, anthropometric, burn characteristic, and existing comorbid were documented from subjects’ medical records. Blood samples from subjects were collected immediately via venipuncture. D-dimer was analyzed with Enzyme-Linked Fluorescent Assay (ELFA) method, hematology and coagulation profiles were also assessed using hematology analyzer and automated coagulation system, respectively. Meanwhile, hepatic and renal function were analyzed with chemistry analyzers.RESULTS: Most burn subjects (18 of 20) demonstrated elevated D-dimer levels. Higher D-dimer levels were associated with increased leukocyte counts and upward trend of RDW-CV and RDW-SD. Further analysis among the subjects with elevated D-dimer level showed significant negative correlations were observed between D-dimer levels and anemia-related parameters, including hemoglobin, erythrocyte count, and hematocrit (all p<0.05). Elevated D-dimer was also associated with immune dysregulation, reflected by increased basophil percentages and decreased immunoglobulin (Ig) levels. Additionally, D-dimer levels showed significant positive correlations with aspartate aminotransferase (AST), alanine aminotransferase (ALT), and blood urea nitrogen (BUN), suggesting a link between hypercoagulability and kidney as well as renal dysfunction following burn injury.CONCLUSION: Leukocyte count, RDW-CV, and RDW-SD are higher in burn patient with elevated D-dimer levels, suggesting that high D-dimer might be correlated with VTE. Elevated D-dimer in burn patients correlates with several VTE risks including anemia, immune dysregulation, and hepatic–renal dysfunction, indicating early coagulation activation and systemic injury following burn injury.
