How do you differentiate iPSC into cardiomyocytes?

Patient-specific cardiomyocytes can easily be derived by reprograming adult somatic cells into iPSCs and then differentiating these into cardiomyocytes. ESCs and iPSCs have the potential to form a teratoma if injected directly into the heart,16 and thus must be differentiated into cardiomyocytes prior to implantation.

How do you identify cardiomyocytes?

Cardiomyocyte shape Surface characteristics and cell shape can be used to identify cardiomyocytes, in addition to several transcription factor genes. Cardiac cells can be identified by contractile myofibrillar proteins, some (and hopefully more to come) surface proteins, and striations along with shape and length.

How do pluripotent stem cells differentiate?

The definition of pluripotent stem cell is based on two properties: self-renewal and potency. Similarly to ES, iPS cells can be expanded indefinitely and they are capable to differentiate in all the derivatives of the three germ layers.

What is cardiomyocyte differentiation?

Cardiomyocytes are the chief cell type in the heart and their coordinated contraction as a mass is responsible for the pumping of blood around the developing embryo. Cardiac specification occurs very early on during embryonic development.

What do cell surface markers do?

Cell markers, also known as cell surface antigens, serve as monograms to help identify and classify cells. The majority of them are molecules or antigens within cell’s plasma membrane.

What is difference between totipotent and pluripotent?

The difference between totipotent and pluripotent cells is only that totipotent cells can give rise to both the placenta and the embryo. As the embryo grows these pluripotent cells develop into specialized, multipotent stem cells. There are multipotent stem cells for all of the different types of tissue in the body.

What are atrial cardiomyocytes?

Atrial and ventricular cardiomyocytes form the muscular walls of the heart (the myocardium). Atrial myocytes have a different ultrastructure compared to ventricular myocytes. They have differential gene expression patterns regarding, e.g., transcription factors, structural proteins, and ion channels (2).

What is a Myocardiocyte?

Also known as myocardiocytes, cardiomyocytes are cells that make up the heart muscle/cardiac muscle. As the chief cell type of the heart, cardiac cells are primarily involved in the contractile function of the heart that enables the pumping of blood around the body.
