Mature teratomas are designated grade 0, displaying mature and well-differentiated tissues belonging to all three germinal layers
8-9) Teratomas are embryonic tumors that are derived from two to three germinal layers
Teratomas are composed of derivatives of all three germinal layers
, arranged in haphazard manner.
Background: Teratomas are usually derived from all the three germinal layers
Arising from all 3 germinal layers
, teratomas are heterogeneous masses that may be intracranial or extracranial.
5) In the case presented here, all 3 germinal layers
The company reports that during the past 2 years its scientists have successfully differentiated the cloned MLPCs into tissues representative of the 3 germinal layers
, including neural stem cells, nerve cells, liver/pancreas precursors, skeletal muscle, fat cells, bone cells and blood vessels.
Figure 3 demonstrates the tumor histology, which shows derivatives of all 3 germinal layers
For example, research shows the cord blood-derived MLPC stem cell has the ability to turn into cells representative of the three different embryonic germinal layers
, including liver and pancreatic precursor cells, terminally differentiated liver cells, lung cells, fat cells, cartilage cells, bone cells, skeletal muscle, blood vessels, neural stem cells and nerve cells.
Dermoid cysts can be composed of elements descending from all three of the germinal layers
, but in ovarian DCs, ectodermic differentiation frequently occurs.
Researchers then differentiated the MLPC into cell types representative of the three germinal layers
The results of the University of Minnesota study also further demonstrate the MLPC's unique ability as a cord blood stem cell to expand and differentiate -- in a controllable fashion -- into tissues representative of the three germinal layers
