: This systematic review aims to evaluate the use of mesenchymal stem cells, particularly those derived from bone marrow, adipose tissue, and dental pulp in maxillofacial and oral surgery, focusing on their regenerative potential, clinical applications, and integration with biomaterials. : Mesenchymal stem cells are multipotent stem cells known for their immunomodulatory and regenerative abilities. Their low immunogenicity and differentiation capacity make them ideal for treating craniofacial defects and enhancing soft tissue repair. : The review followed PRISMA guidelines and was registered in PROSPERO. The literature was searched across PubMed, Scopus, and Web of Science from 2009 to 2024. Twelve studies met the inclusion criteria and were analyzed for clinical efficacy and methodological quality. : Clinical trials demonstrated the safety and regenerative benefits of mesenchymal stem cell in bone and soft tissue reconstruction. Adipose-derived stem cell and dental pulp stem cell showed favorable outcomes in angiogenesis and healing, while bone marrow's cell proved effective in bone regeneration, particularly when combined with scaffolds. : Although results are promising, limitations remain in consistency and long-term outcomes. Optimizing scaffold integration, preservation methods, and delivery techniques is crucial. Mesenchymal stem cell-based therapies represent a powerful, minimally invasive alternative to traditional grafting in oral and maxillofacial surgery.

Stemming from human immune organs, tonsil-derived mesenchymal stem cells (TMSCs) hold unique strengths in differentiation potential and immune regulatory functions. These characteristics make them valuable for therapeutic applications, particularly in regenerative medicine and autoimmune disease treatment, as they can modulate immune responses and promote tissue repair. Their ability to interact with various cell types and secrete a range of bioactive molecules further enhances their role in orchestrating healing processes, making them a promising avenue for innovative therapies aimed at restoring balance in the immune system and facilitating recovery from injury or disease.

The role of inflammation in the regulation of acute myeloid leukemia (AML) and stressed hematopoiesis is significant, though the molecular mechanisms are not fully understood. Here, we found that mesenchymal stromal cells (MSCs) had dysregulated expression of the inflammatory cytokine S100A8 in AML. Upregulating S100A8 in MSCs increased the proliferation of AML cells in vitro.

Lymphangioleiomyomatosis (LAM) is a rare lung disease caused by hyperactivation of the mechanistic/mammalian target of rapamycin 1 (mTORC1) growth pathway in a subset of mesenchymal lung cells. Histopathologically, LAM lesions have been described as immature smooth muscle-like cells positive for the immature melanocytic marker HMB45/PMEL/gp100 and phosphorylated ribosomal protein S6 (pS6). Advances in single cell sequencing (scRNA-seq) technology allowed us to group LAM cells according to their expression of cancer stem cell (CSC) genes and identify three clusters: a high CSC-like state (SLS), an intermediate state, and a low CSC-like inflammatory state (IS).

Emphysema is characterized by chronic alveolar destruction. Lipofibroblasts (LIF) are crucial in the stem cell niche surrounding alveolar type II (AT2) cells and may contribute to alveolar regeneration. We aim to determine whether emphysema is associated with LIF reduction and whether Sterol regulatory binding protein (SREBP) activation promotes LIF differentiation and fibroblast stem cell niche properties.

Human cord blood (CB) myeloid progenitor reprogramming to a high-fidelity human induced pluripotent stem cell (hiPSC) state can be achieved using non-integrating episomal vectors and stromal signals. These conventional, primed CB-hiPSC lines can subsequently be chemically reverted with high efficiencies to a blastomere-like Tankyrase/PARP Inhibitor-Regulated Naive Stem Cell (TIRN-SC) state with functional totipotency. PARP-regulated TIRN-SCs are human stem cells with high epigenetic plasticity, stable epigenomic imprints, and have greater differentiation potency than conventional, lineage-primed hiPSCs.
