ESCs and iPSCs

Embryonic stem cells (ESCs) are found in the inner cell mass of blastocysts. They are considered immortal as they have an unlimited capacity for self-renewal in an undifferentiated state. Like ESCs, induced pluripotent stem cells (also known as iPS cells or iPSCs) are also pluripotent stem cells that can be generated directly from adult cells, they can propagate indefinitely.

Embryonic stem cells (ESCs) are found in the inner cell mass of blastocysts. They are considered immortal as they have an unlimited capacity for self-renewal in an undifferentiated state. ESCs have the ability to differentiate into cells from all three germ layers (endoderm, mesoderm and ectoderm).

Embryonic stem cells (ESCs) are pluripotent cells and differentiation is tightly controlled by growth factor, cytokines and epigenetic processes such as DNA methylation and chromatin remodeling. ESCs divide into two cells: they can either differentiated in to two identical daughter cells, or one undergoes self-renewal and produces an identical stem cell, and the other cell be will differentiated.

Induced pluripotent stem cells (also known as iPS cells or iPSCs) can be generated directly from adult cells. Like ESCs, they can propagate indefinitely. Given the right cocktail of factors and or small molecules, they can be reprogrammed to differentiate into many types of somatic cells, including neurons, cardiomyocytes, and hepatocytes. Stem cell therapies using these types of cells are now entering the clinic.

ESCs and iPSCs have great potential for use in regenerative medicine to repair damaged tissue, and in organ transplantation to generate human organ tissues. The use of iPSCs in medicine has the advantage that the cells are autologous, limiting the risk of immune rejection.

Stem cells offer the potential for treating many diseases including cancer and neurodegenerative conditions, such as Alzheimer's, Parkinson's or Huntington's diseases, or repairing damaged tissue from myocardial infarction.
