Article Abstract
Background: Cardiovascular disease (CVD) remains the leading cause of mortality worldwide. The human myocardium has a limited regenerative capacity, prompting the development of innovative strategies to restore cardiac function. Stem cells (SCs) and bioartificial tissues (BATs) have emerged as promising tools in regenerative cardiology for myocardial repair and functional recovery.
Methods: This review analyzes current preclinical and clinical research focused on SC- and BAT-based therapies for CR. Literature was identified through comprehensive database searches. Studies evaluating cardiomyocyte differentiation, integration into host tissue, vascularisation and electromechanical properties were selected. Emphasis was placed on therapeutic potential, safety and translational challenges.
Results: SCs, including embryonic and mesenchymal stem cells, demonstrated potential to differentiate into cardiomyocyte-like cells and contribute to myocardial restoration. When combined with biomaterial scaffolds or decellularized matrices, SCs showed improved survival, structural support, and functional integration. BATs, such as engineered heart tissue, replicated native myocardial architecture and supported synchronized contraction. Despite these advances, concerns persist regarding immunogenicity, arrhythmias, and long-term efficacy. Technical hurdles in large-scale production and personalised application remain unresolved.
Conclusions: SC- and BAT-based therapies offer innovative avenues for repairing damaged myocardium. Their application could revolutionise treatment strategies for heart failure and post-infarction remodelling. However, clinical translation requires addressing immune compatibility, arrhythmic risk and manufacturing limitations. Interdisciplinary collaboration and regulatory standardisation are essential for their future clinical adoption.

Neural stem cells (NSCs) are multipotent stem cells with self-renewal capacity, able to differentiate into all neural lineages of the central nervous system, including neurons, oligodendrocytes, and astrocytes; thus, their proliferation and differentiation are essential for embryonic neurodevelopment and adult brain homoeostasis. Dysregulation in these processes is implicated in neurological disorders, highlighting the need to elucidate how NSCs proliferate and differentiate to clarify the mechanisms of neurogenesis and uncover potential therapeutic targets. MicroRNAs (miRNAs) are small, post-transcriptional regulators of gene expression involved in many aspects of nervous system development and function.

Retinal ganglion cells (RGCs) are highly compartmentalized neurons whose long axons serve as the sole connection between the eye and the brain. In both injury and disease, RGC degeneration occurs in a similarly compartmentalized manner, with distinct molecular and cellular responses in the axonal and somatodendritic regions. The goal of this study was to establish a microfluidic-based platform to investigate RGC compartmentalization in both health and disease states.

Background: Sjögren's syndrome (SS) is a chronic autoimmune disease delineated by excessive lymphocyte infiltration to the lacrimal or salivary glands, leading to dry eye and dry mouth. Exosomes secreted from mesenchymal stem cells (MSC) are known to have anti-inflammatory and tissue regeneration abilities. This study endeavored to demonstrate the effect of MSC-derived exosomes on the clinical parameter of dry eyes and associated pathology in SS mouse model.
