        <description><![CDATA[Mitochondrial dysfunction, driven by genetic mutations or oxidative stress, is a central contributor to the onset and progression of ophthalmic diseases. In recent years, intercellular mitochondrial transfer (MT) has emerged as a novel mechanism of cellular communication and repair in ocular tissues. MT occurs through tunneling nanotubes, extracellular vesicles (EVs), cell fusion, or transmitophagy, and has been shown to support photoreceptor survival, maintain retinal homeostasis, and protect against oxidative injury. Mesenchymal stem cells (MSCs), owing to their remarkable reparative and immunomodulatory properties, have attracted particular attention as efficient mitochondrial donors. Evidence from experimental models demonstrates that MSC-mediated MT can restore bioenergetics, mitigate oxidative stress, and rescue cellular function in inherited optic neuropathies, corneal injuries, retinal degenerative diseases, and ischemic retinopathies. This review summarizes current evidence of MT in ophthalmology, highlights the therapeutic contributions of MSCs, discusses the molecular and microenvironmental factors regulating MT efficiency, and outlines unresolved challenges. We further provide perspectives on how mitochondrial transfer may be translated into innovative therapies for ocular disorders.]]></description>

        <description><![CDATA[The potential of mesenchymal stromal cells (MSCs) in the treatment of hemorrhagic stroke has been demonstrated; however, their clinical efficacy remains inconsistent and further comprehensive studies on their mechanism of action are warranted. In this study, the intracerebral hemorrhage (ICH) rat model was used for intravenous infusion of adipose-derived mesenchymal stromal cells (AD-MSCs) 24 h after modeling. Histopathological techniques and single cell transcriptome sequencing techniques were used to study the mechanism of AD-MSCs promoting the repair of damaged brain tissue. The results indicated that AD-MSCs markedly promote the repair of damaged brain tissues and restored neural function. Single-cell transcriptome sequencing further revealed that this therapeutic effect is specifically through the inhibition of monocyte infiltration in injured brain tissue, promotion of resident microglia proliferation and signaling pathways linked to immune response and neuroprotection. These processes are closely tied to the Csf1+ subgroup of AD-MSCs. For acute hemorrhagic stroke, Csf1+ AD-MSCs promote the repair of damaged brain tissue by activating resident microglia and inhibiting monocyte infiltration. This study offers novel insights into the mechanisms underlying MSC-based stroke treatment and supports the potential for stable and efficacious MSC therapies.]]></description>

        <description><![CDATA[Bone fractures and bone loss represent significant global health challenges, with their incidence rising due to an aging population. Despite autologous bone grafts remain the gold standard for treatment, challenges such as limited bone availability, immune reactions, and the risk of infectious disease transmission have driven the search for alternative cell-based therapies for bone regeneration. Stem cells derived from oral tissues and umbilical cord mesenchymal stem cells (MSCs) have shown potential in both preclinical and clinical studies for bone tissue regeneration. However, their limited differentiation capacity and wound healing abilities necessitate the exploration of alternative cell sources. In this study, we generated induced pluripotent stem cells (iPSCs) using a safe, nonviral and mRNA-based approach from human periodontal ligament fibroblasts (PDLF), an easily accessible cell source. These iPSCs were subsequently differentiated into MSCs, referred to as induced MSCs (iMSCs). The resulting iMSCs were homogeneous, highly proliferative, and possessed anti-inflammatory properties, suggesting their potential as a superior alternative to traditional MSCs for regenerative therapy. These iMSCs demonstrated trilineage differentiation potential, giving rise to osteocytes, chondrocytes, and adipocytes. The iMSC-derived osteocytes (iOSTs) were homogeneous, patient-specific and showed excellent attachment and growth on commercial collagen-based membranes, highlighting their suitability for bone tissue regeneration applications. Given their promising characteristics compared to traditional MSCs, PDLF-derived iMSCs are strong candidates for future clinical studies in bone regeneration and other regenerative dental therapies.]]></description>
