Currently available heart valve replacements are limited in long-term performance or fail due to leaflet thickening, lack of growth remodeling potential. In order address these issues, it is necessary mimic multiple factors the native valvular extracellular matrix (ECM) such as architecture, mechanical behavior and biochemical signals. Here, we successfully generated an electrospun PEGdma–PLA scaffold adapted structure properties leaflets. Valvular interstitial cells (VICs) endothelial...

Abstract Bone formation or regeneration requires the recruitment, proliferation, and osteogenic differentiation of stem/stromal progenitor cells. A potent stimulus driving this process is mechanical loading. Osteocytes are mechanosensitive cells that play fundamental roles in coordinating loading-induced bone via secretion paracrine factors. However, exact mechanisms by which osteocytes relay signals to these poorly understood. Therefore, study aimed demonstrate potency mechanically...

Elastic fibers are essential for the proper function of organs including cardiovascular tissues such as heart valves and blood vessels. Although (tropo)elastin production in a tissue-engineered construct has previously been described, assembly to functional elastic vitro using human cells highly challenging. In present study, we seeded primary isolated vascular smooth muscle (VSMCs) onto 3D electrospun scaffolds exposed them defined laminar shear stress customized bioreactor system....

Cardiovascular disease remains a leading cause of mortality and morbidity worldwide. Embryonic stem cell-derived cardiomyocytes (ESC-CMs) may offer significant advances in creating vitro cardiac tissues for modeling, drug testing, elucidating developmental processes; however, the induction ESCs to more adult-like CM phenotype challenging. In this study, we developed bioreactor system employ pulsatile flow (1.48 mL/min), cyclic strain (5%), extended culture time improve maturation murine...

One major obstacle to the application of stem cell-derived cardiomyocytes (CMs) for disease modeling and clinical therapies is inability identify developmental stage these cells without need genetic manipulation or utilization exogenous markers. In this study, we demonstrate that Raman microspectroscopy can non-invasively embryonic cell (ESC)-derived chamber-specific CMs monitor maturation. Using marker-free approach, peaks were identified atrial ventricular CMs, ESCs successfully...

Synthetic polymeric materials have demonstrated great promise for bone tissue engineering based on their compatibility with a wide array of scaffold-manufacturing techniques, but are limited in terms the bioactivity when compared to naturally occurring materials. To enhance regenerative properties these materials, they commonly functionalised bioactive factors guide growth within developing tissue. Extracellular matrix vesicles (EVs) play an important role facilitating endochondral...

Bioreactors are essential cell and tissue culture tools that allow the introduction of biophysical signals into in vitro cultures. One major limitation is need to interrupt experiments sacrifice samples at certain time points for analyses. To address this issue, we designed a bioreactor combines high-resolution contact-free imaging continuous flow closed system compatible with various types microscopes. The high throughput fluid was combined two-photon fluorescence lifetime microscopy...

Human distal upstream element (Fuse) binding protein 1 (FUBP1) is a transcriptional regulator of c-Myc and represents an important prognostic marker in many cancers. Therefore, the present study aimed to investigate whether FUBP1 could combine with participate progression colon cancer. Detection expression was done through reverse transcription-quantitative PCR (RT-qPCR), combination detected by immunoprecipitation assay. Cell counting kit (CCK)-8, colony formation, transwell wound healing...

Tracking the distribution and differentiation of stem cells by high-resolution imaging techniques would have significant clinical research implications. In this study, a model cell-penetrating peptide was used to carry gadolinium particles for magnetic resonance (MRI) mesenchymal (MSCs). MSCs were isolated from rat bone marrow identified osteogenic in vitro. The labeled with fluorescein-5-isothiocyanate (FITC) synthesized solid-phase synthesis method. Fluorescein analysis confirmed that new...
