in spite of serious cardiotoxicity side-effects, doxorubicin is frequently used for treatment of several types of cancers. isolated human adult cardiomyocytes could be the best model for assessing drug-induced cardiotoxicity, while harvesting mature cardiomyocytes is restricted by some limitations such as biopsy size, cell numbers, viability, proliferative capacity and their disability to be pa...

background dox is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. however, its cardiac toxicity limits the clinical usefulness of this drug. previous reports have shown corticosteroids induce a cytoprotective effect on cardiomyocytes. mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for as...

introduction: lactate dehydrogenase is one of the cardiac enzyme markers, studied in vivo. in the present study, activity and kinetic properties of enzyme extracted from cardiomycytes derived from mouse embyronic stem cell in vitro were compared with enzyme extracted mouse neonatal from cardiomyocytes in vivo. material and methods: mouse embryonic stem cells were cultured and differentiated and...

Induction of cardiomyocyte proliferation, the most promising approach to reverse myocardial attrition, has been gaining importance as a therapy for cardiovascular disease. Hypoxia and macrophages were previously independently reported to promote cardiomyocyte proliferation in mice. However, whether hypoxia promotes cardiomyocyte proliferation in humans, and the association between hypoxia and m...

Cardiomyocyte Monitoring In article number 2202235, Chunyu Chang, Donghui Zhang, and co-workers develop micropatterned hydrogels with anisotropic structural colors by locking shear-oriented tunicate cellulose nanocrystals (TCNCs) in hydrogel networks through situ polymerization. The autonomous beating of cardiomyocytes drives synchronous deformations the hydrogels, causing periodic changes tran...

Sodium-glucose cotransporter 2 inhibitors offer cardiovascular and renal benefits in patients with chronic kidney disease through not yet clearly defined mechanisms. Juni et al. showed that sodium-glucose inhibitor empagliflozin exposure vitro can restore cardiomyocyte function by counteracting harmful effects of uremic serum on the endothelium-cardiomyocyte crosstalk between endothelial cells ...

objective(s):cardiomyocytes have small potentials for renovation and proliferation in adult life. the most challenging goal in the field of cardiovascular tissue engineering is the creation of an engineered heart muscle. tissue engineering with a combination of stem cells and nanofibrous scaffolds has attracted interest with regard to cardiomyocyte creation applications. human adipose-derived s...

AIMS Adipose stromal cells and dissociated brown adipose tissue have been shown to generate cardiomyocyte-like cells. However, it is not clear whether white mature adipocytes have the same potential, even though a close relationship has been found between adipocytes and vascular endothelial cells, another cardiovascular cell type. The objective of this study was to examine if white adipocytes w...

Although it is accepted that the heart has a limited potential to regenerate cardiomyocytes following injury and that low levels of cardiomyocyte turnover occur during normal ageing, quantification of these events remains challenging. This is in part due to the rarity of the process and the fact that multiple cellular sources contribute to myocardial maintenance. Furthermore, DNA duplication wi...

BACKGROUND The fibroblast growth factor (FGF) family is essential to normal heart development. Yet, its contribution to cardiomyocyte differentiation from stem cells has not been systemically studied. In this study, we examined the mechanisms and characters of cardiomyocyte differentiation from FGF family protein treated embryonic stem (ES) cells and induced pluripotent stem (iPS) cells. METH...
