Embryonic Stem Cells

ESC Poster

Embryonic stem cells are derived from a very early stage embryo known as a “blastocyst” – a cluster of cells that resemble a hollow, microscopic sphere. Unlike adult stem cells, which are restricted to producing limited cell types, embryonic stem cells have the potential to generate every cell type in the body.

The advantages of ESCs are:

Make cell lines

Turn into many tissues  (pluripotency)

No rejection if personalized cell line

Disadvantages:

Generate tumors (cancer) when injected into animals

Control of differentiation and cell division

Ethical issues

Limited number of cell lines

Rejection potential if from a different donor

Photomicrograph of Mesenchymal Stem Cells

05/08/2012

Here is a Scanning Electron Micrograph of Mesenchymal Stem Cells as mentioned in the previous post. This is an accurate 3D representation of what they look like. Remember, MSCs can become many different kinds of cells like marrow cells, muscle, bone, cartilage and more. They are known for being long and branch-like.

The Mesengenic Process

Mesenchymal stem cells are considered multipotent because they differentiate (or become) a variety of cell types. They go on to create cells found in bone marrow, bone, cartilage, tendon, muscle and fat as seen above in the Mesenchymal Stem Cell Breakdown Chart above.
