mRNA of genes (tgfβ, il6, il10, il1β, and vegf165) involved in cell proliferation, inflammatory, anti-inflammatory, and angiogenic processes were detected and quantified in cultures of mesenchymal stromal cells of different passages derived from human extraembryonic tissues (amniotic sac, umbilical cord, chorionic villi and trophoblast of the placenta). The concentrations of IL-10, IL-6, IL-1β, and TGFβ were measured.

Cleft lip and palate (CL/P) are prevalent congenital anomalies with complex genetic causes. The G874A mutation of T-box transcription factor 22 (TBX-22) gene is notably associated with CL/P, while the underlying mechanism remains to be clarified. Studies have shown that the restriction of epithelial-mesenchymal transformation (EMT) process in medial edge epithelial cells (MEEs) is crucial for CL/P development.

Background: Recent studies show that M1 macrophages accumulate predominantly in non-eosinophilic chronic rhinosinusitis with nasal polyps (neCRSwNP). However, the precise mechanisms regulating M1 macrophages and their impact on the epithelial barrier remain unclear.
Objective: We aim to investigate the expression and regulatory role of SLAMF8, a molecule exclusively expressed in myeloid cells, in M1 macrophage polarization and its potential contribution to neCRSwNP development.

Gastric cancer mesenchymal stem cells (GC-MSCs) are a crucial component of the gastric cancer microenvironment, exerting a pivotal influence on the formation of a suppressive immune microenvironment and the progression of gastric cancer. In this study, we utilized GC-MSCs to co-culture peripheral blood mononuclear cells (PBMCs) obtained from both gastric cancer patients and healthy individuals in a proportionate manner by direct cell-to-cell contact. Our findings reveal that co-culture of GC-MSCs with PBMCs led to a notable reduction in CD8 T cells percentages and an increase in surface PD-1 expression levels on CD8 T cells.

Introduction: Intestinal lymphoma may be latent in some dogs with chronic inflammatory enteropathy. Mesenchymal stromal cells (MSCs) have potential therapeutic applications for refractory chronic inflammatory enteropathy, but their impact on the development of potential intestinal lymphomas has not yet been evaluated. Therefore, this study was performed to investigate the effect of canine adipose-derived MSCs (cADSCs) on the growth of canine lymphoma cell lines to assess the safety of MSC-based therapy in terms of pro- and anti-tumorigenic effects.

Background: Human mesenchymal stromal cells (MSCs) possess regenerative potential due to pluripotency and paracrine functions. However, their stemness and immunomodulatory capabilities are sub-optimal in conventional two-dimensional (2D) culture.
Aim: To enhance the efficiency and therapeutic efficacy of MSCs, an -like 3D culture condition was applied.
