Treatment of spinal cord cells with epidermal growth factor (EGF) promoted the proliferation and maturation of astrocytes during development. EGF (30 ng/ml, 4 days) increased CBS protein expression and the number of CBS-expressing astrocytes in the culture. A high cell density also increased CBS expression, and EGF was able to increase CBS expression when cellular proliferation was inhibited.

In this study, radioresistant cell lines A549R and H1299R were constructed by repeatedly irradiating A549 and H1299 cells with gradient doses of X-rays. CCK-8, cell cloning, flow cytometry, RT-qPCR, Western blot, sphere formation detection, and other methods were used for experimental exploration. This study revealed that the radioresistance of LUAD cells was related to their stemness. By inhibiting KLF4, SOX2, CD133, and ALDH1A1 expression, EC treatment increased radiosensitivity and reduced cell sphere formation. Also, FOXM1 expression was upregulated in LUAD and in radioresistant LUAD cells. Knocking down FOXM1 inhibited the stemness of radioresistant LUAD cells. Mechanistically, EC inhibited radiotherapy-resistant LUAD cell stemness by downregulating FOXM1 expression, thereby increasing radiosensitivity. In summary, our study revealed that EC inhibited radiotherapy resistance in LUAD cells through downregulating FOXM1, and it provides a theoretical framework for treating LUAD clinically.</p>","PeriodicalId":13340,"journal":{"name":"In Vitro Cellular & Developmental Biology.

In veterinary medicine, adipose tissue is the most common source of MSCs to treat canine disease, but the collection process is invasive, and the cells are influenced by the age and health conditions of the donor. These problems enhance interest in seeking alternative MSC sources, such as perinatal tissues. In this study, we developed and validated an optimized protocol for isolating canine umbilical cord MSCs for application in veterinary therapies. Umbilical cords obtained from cesarean sections were processed using three different protocols, involving combinations of mechanical and enzymatic tissue dissociation. The cells were cultured and evaluated for membrane receptors by flow cytometry to identify MSCs and assessed for their differentiation capacity. The number of cells obtained did not differ significantly between the combined protocol with trypsin and collagenase (TRIP + COL) and the collagenase protocol (COL). In in vitro culture, the combined TRIP + COL and COL yielded 12 to 14 times more cells, respectively, in the first passage than the explant (EXP) group, within fewer days of culture. Additionally, the cells obtained from these protocols showed a greater capacity for expansion over passages, and cells from both protocols showed fibroblast-like morphology and proliferation capacity up to the sixth passage. The cells obtained from these protocols were characterized by phenotype: CD45<sup>-</sup>, CD34<sup>-</sup>, CD14<sup>-</sup>, HLA-DR<sup>-</sup>, CD29<sup>+</sup>, CD44<sup>+</sup>, and CD90<sup>+</sup>, consistent with MSC identity. However, CD90 expression in the cells decreased significantly at sixth passage. Regarding differentiation, cells obtained from the COL protocol showed a capacity for commitment to the chondrogenic and osteogenic lineages. In conclusion, the COL and TRIP + COL protocols were more effective than the EXP protocol in terms of both the number and quality of isolated cells.

This study investigates the role of SPARC in hypertension, focusing on its impact on endothelial dysfunction.Using the GSE75815 dataset from the GEO database, we identified 71 differentially expressed genes (DEGs) associated with hypertension. Pathway analyses and protein-protein interaction networks constructed through the STRING database highlighted six hub genes, with further evaluation based on Comparative Toxicogenomics Database (CTD) scores. Immune cell profiling via ImmuCellAI revealed an increase in naive B cells, positively correlating with hub gene expression.Experimental validation in human umbilical vein endothelial cells (HUVECs) treated with angiotensin II demonstrated that SPARC downregulation reduced apoptosis and BAX expression. Silencing SPARC enhanced endothelial cell proliferation, migration, and nitric oxide production, counteracting angiotensin II-induced damage. Notably, angiotensin II upregulated SPARC secretion, suggesting its critical role in mediating endothelial dysfunction.These findings establish SPARC as a key contributor to the molecular pathways underlying hypertension. Targeting SPARC may represent a novel therapeutic strategy to mitigate endothelial dysfunction and improve outcomes for hypertensive patients.Our findings highlight SPARC as a key player in the molecular pathways of hypertension.
