iPS cell modeling of cardiometabolic diseases.

Cardiometabolic diseases encompass simple monogenic enzyme deficiencies with well-established pathogenesis and clinical outcomes to complex polygenic diseases such as the cardiometabolic syndrome. The limited availability of relevant human cell types such as cardiomyocytes has hampered our ability to adequately model and study pathways or drugs relevant to these diseases in the heart. The recent discovery of induced pluripotent stem (iPS) cell technology now offers a powerful opportunity to establish translational platforms for cardiac disease modeling, drug discovery, and pre-clinical testing

Rebuilding insight into the pathophysiology of Alzheimer's disease through new blood-brain barrier models.

The blood-brain barrier is a unique function of the microvasculature in the brain parenchyma that maintains homeostasis in the central nervous system. Blood-brain barrier breakdown is a common pathology in various neurological diseases, such as Alzheimer's disease, stroke, multiple sclerosis, and Parkinson's disease. Traditionally, it has been considered a consequence of neuroinflammation or neurodegeneration, but recent advanced imaging techniques and detailed studies in animal models show that blood-brain barrier breakdown occurs early in the disease process and may precede neuronal loss. Th

Human Adipose-Derived Stem Cells Reduce Cellular Damage after Experimental Spinal Cord Injury in Rats.

Traumatic spinal cord injury (SCI) is a devastating condition without an effective therapy. Cellular therapies are among the promising treatment strategies. Adult stem cells, such as mesenchymal stem cells, are often used clinical research for their immunomodulatory and regenerative potential. This study aimed to evaluate the effect of human adipose tissue-derived stem cells (ADSC) infusion through the cauda equina in rats with SCI. The human ADSC from bariatric surgery was isolated, expanded, and characterized. Wistar rats were subjected to blunt SCI and were divided into four groups. Two exp

The role of physical rehabilitation in stem cell transplantation patients.

The purpose of this paper is to review the evidence for the role of physical rehabilitation in stem cell transplantation patients. We will also review the literature and discuss professional experiences on how rehabilitation can play a role in stem cell transplant care and survivorship. Hematopoietic stem cell transplantation (HCT) is a procedure that has evolved substantially over the years to help treat multiple conditions, particularly hematologic malignancies. HCT can be very stressful on the body and can leave patients weakened and sometimes quite debilitated. Supportive care measures hav

Novel Treatments for Mantle Cell Lymphoma: From Targeted Therapies to CAR T Cells.

Mantle cell lymphoma is a rare B-cell non-Hodgkin's lymphoma that retains a sobering prognosis despite an extensive research effort. Mantle cell lymphoma remains incurable even with aggressive, and at times toxic, chemoimmunotherapy with early incorporation of autologous stem cell transplantation. Given this, attention has turned to the use of targeted therapies addressing dysregulation of B-cell signaling pathways. Drugs such as immunomodulatory agents, proteasome inhibitors, and Bruton's tyrosine kinase inhibitors have shown success in the relapsed/refractory population, and there is ongoing

Isolation of Human Umbilical Cord Blood Hematopoietic Stem Cells and Directed Differentiation Into Megakaryocytes.

Platelets originate from megakaryocytes, whose generation involves a series of biological processes including directed differentiation, proliferation, polyploidization, and maturation of hematopoietic stem cells. Abnormalities in megakaryocyte development and maturation can lead to quantitative and functional defects in platelets, thereby contributing to hemostatic or thrombotic disorders as well as the development of malignancies. Investigating megakaryocyte development and maturation and platelet production can provide important theoretical foundations for the diagnosis and treatment of thro

Current status of nano-embedded growth factors and stem cells delivery to bone for targeted repair and regeneration.

UNLABELLED: Bone-related diseases like osteoarthritis and osteoporosis impact millions globally, affecting quality of life. Osteoporosis considerably enhances the probability of bone fractures of the wrist, hip, and spine. Enhancement and acceleration of functional bone development can be achieved through the sustained delivery of growth factors (GFs) and cells in biomaterial carriers. The delivery of bioactive compounds in a targeted, spatiotemporal way that most closely resembles the natural defect repair process can be achieved by designing the carrier system with established release kineti

Concise review: Preclinical studies on human cell-based therapy in rodent ischemic stroke models: where are we now after a decade?

Stroke, a debilitating brain insult, afflicts millions of individuals globally each year. In the last decade, researchers have investigated cell-based therapy as an alternative strategy to improve neurological outcome following stroke. This concise review critically examines preclinical reports using human adult and fetal stem/progenitor cells in rodent models of ischemic stroke. As we enter the second decade of study, we should aim to optimize our collective likelihood to translational success for stroke victims worldwide. We advocate international consensus recommendations be developed for f

TIM-3 as an immune and leukemia stem-cell biomarker in acute myeloid leukemia: diagnostic laboratory and translational perspectives.

Despite improvements in ELN-based risk stratification, acute myeloid leukemia (AML) still faces three significant challenges: relapse, resistance to therapy, and measurable residual disease (MRD). T-cell immunoglobulin and mucin-domain-containing molecule 3 (TIM-3/HAVCR2) is a clinically relevant AML biomarker, as it is enriched in CD34+CD38- AML leukemia stem cells, with limited expression in normal hematopoietic stem cells, and is involved in immune-checkpoint disruption in the leukemic microenvironment. This review focuses on the diagnostic, prognostic, and translational value of TIM-3 in A

The dual role of exosomes in renal fibrosis and their potential for clinical translational applications.

Renal fibrosis is the core pathological process in the progression of chronic kidney disease to its end stage. There is to date no novel therapeutic strategies that are both safe and efficient in reversing renal fibrosis in humans. Exosomes, as key mediators of intercellular communication, play significant regulatory roles in renal fibrosis. Translating mechanistic studies on exosome-mediated promotion or inhibition of renal fibrosis into clinically applicable anti-fibrotic strategies remains a challenging issue in this field. In this review, we systematically elucidate the distinct dual role

Malignant gliomas: new translational therapies.

Malignant gliomas are the most common primary brain tumors in adults and carry a dismal prognosis. Despite aggressive therapy with maximal safe surgical resection, radiation and chemotherapy, these tumors invariably are refractory to or become resistant to treatment and recur. Gliomas are highly infiltrative cancers and display remarkable genetic heterogeneity making them challenging to treat. Recent progress has been made in understanding the molecular and genetic composition of these tumors and from this, promising new targets for therapy have emerged. In particular, anti-angiogenesis therap

The Immunomodulatory Role of Cell-Free Approaches in SARS-CoV-2-Induced Cytokine Storm-A Powerful Therapeutic Tool for COVID-19 Patients.

Currently, there is still no effective and definitive cure for the coronavirus disease 2019 (COVID-19) caused by the infection of the novel highly contagious severe acute respiratory syndrome virus (SARS-CoV-2), whose sudden outbreak was recorded for the first time in China in late December 2019. Soon after, COVID-19 affected not only the vast majority of China's population but the whole world and caused a global health public crisis as a new pandemic. It is well known that viral infection can cause acute respiratory distress syndrome (ARDS) and, in severe cases, can even be lethal. Behind the

Dental stem cell-derived extracellular vesicles for oral tissue regeneration: Mechanisms, engineering strategies, and clinical translation.

OBJECTIVE: The regeneration of complex oral and maxillofacial tissues remains a significant clinical challenge. While stem cell-based therapies have shown promise, their clinical translation is impeded by safety concerns, immune rejection risks, and manufacturing standardization hurdles. Cell-free therapies utilizing extracellular vesicles derived from dental mesenchymal stem cells (DMSC-EVs) have therefore attracted increasing interest as a potential alternative strategy warranting systematic investigation. DESIGN: This narrative review, structured around a systematic literature search, crit

Who Tells the Story of the Treatment of Androgenetic Alopecia?-A Bibliometric Analysis From 2003 to 2023.

BACKGROUND: Androgenetic alopecia (AGA) is a common form of nonscarring hair loss that affects both men and women, significantly influencing psychological well-being and quality of life. Although AGA accounts for over 90% of male hair loss, there has been limited bibliometric analysis to guide the direction of research and the development of treatments. METHODS: A thorough literature search was performed using the Web of Science database, resulting in the identification of 2203 articles on AGA treatment published between 2003 and 2023. The search was restricted to English-language peer-review

Translational Potential of Stem Cell-based Therapies in the Treatment of Neonatal Hypoxic-ischemic Brain Injury.

Neonatal hypoxia-ischemia is a leading cause of neonatal death in both developed and developing countries. The consequences of hypoxic-ischemic injury affect the rest of the child's life, often resulting in intellectual or motor disability that persists into adulthood. To date, therapeutic hypothermia (TH) appears to be the only available intervention aimed at limiting brain injury and is recognized as the "gold standard" in neonatal intensive care. The basic mechanisms of neuroprotection achieved by temporal cooling involve the reduction of free radical activity, suppression of the inflammato

Leducq Transatlantic Network of Excellence to Cure Phospholamban-Induced Cardiomyopathy (CURE-PLaN).

The deletion of Arginine 14 of the phosholamban gene (PLN p.R14del) is associated with the pathogenesis of an inherited form of cardiomyopathy with prominent arrhythmias. Patients carrying the PLN R14del mutation are at risk of developing dilated cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy. Although the genetic etiology is well defined, the molecular mechanism underlying the pathogenesis of PLN R14del-cardiomyopathy is unknown. Our CURE PLaN network, funded by the Foundation Leducq, will bring together leading scientists, clinicians, and patients to elucidate the genotype
