TempoATP – a snapshot

Genetically encoded biosensors have become popular and powerful LIVE-cell reporters in recent years (see reference here). These biosensors can be incorporated into a variety of human inducible pluripotent stem cells (iPSCs) and iPSC-derived cell types (such as neurons, glial cells, kidney cells, and cardiomyocytes, just to name a few). Previously, we discussed the biosensors and how they are used in research (here). TempoATP biosensor (image shown above) is a LIVE-cell reporter that tracks intracellular ATP levels in real time (from seconds to hours).

Cardiomyocytes are cardiac muscle cells. They are terminally differentiated and facilitate contractile forces (“beatings”) of the heart. Grown in vitro as a monolayer sheath, cardiomyocytes are connected by gap junction proteins that help synchronize contraction-relaxation cycles of the cardiomyocytes. Cardiomyocytes may be used in various in vitro or in vivo studies; transplantation into normal or diseased systems; cardiac toxicology studies; or cardiovascular developmental studies. Cardiomyocytes have a high mitochondrial density, which allows them to produce adenosine triphosphate (ATP) quickly, making them highly resistant to fatigue.

Most of us will remember from high school biology class that kidneys comprise part of the excretory system and function in toxin removal, maintaining electrolyte homeostasis and regulating the body’s acid-base balance. Beyond this, proper kidney function is also critical for the secretion of several important hormones such as erythropoietin and renin, which regulate red blood cell production and arterial blood pressure, respectively. Given the complex roles of the kidney, it’s no surprise that its structure is just as complex with many different parts and cell types working together to carry out its functions.  (more…)Tell us more...
