Mesoderm: The middle cell of embryonic tissue
which forms bone, connective tissue, muscle, blood, vascular and lymphatic tissue.
3] The fact that patients were their own source of tissue meant that the method was free from ethical concerns associated with use of human embryonic tissue
and the risk of immunoreactions, graft rejection, and need for long-term immunosuppressive treatment.
In all mammals mesenchyme eventually differentiates into three embryonic tissues
-- the endoderm, the mesoderm, and the ectoderm.
It is defective in a rare human birth defect that results in a shortage or absence of sweat glands, misshapen and absent teeth, and loss of hair follicles all appendages that develop from the same embryonic tissue
They have, for the first time, derived and purified lens epithelium -- the embryonic tissue
from which the lens of the eye develops.
As the name implies, the former are derived from embryonic tissue
and possess the greatest potential to differentiate into a wide range of cell types, although it has proven difficult to direct their differentiation pathway.
Scientists have previously shown that embryonic tissue
transplants can be used to grow new kidneys inside rats.
If you didn't understand their real agenda, it would amaze you to know that in the very same time frame there were a series of amazing studies that documented the great promise of sources other than human embryonic tissue
- - cloned or otherwise - - in addressing a whole host of medical problems.
In its newly identified function, corticotropin-releasing hormone (CRF) stimulates the production of a protein previously found to prevent maternal immune cells from attacking embryonic tissue
The blastocyst must be treated with the respect appropriate to early human embryonic tissue
The capacity of human mesenchymal stem cells to regenerate tissue follows a sequence of events similar to that of embryonic tissue
Using the Mexican axolotl as a model to represent the evolutionary lineage leading to land animals, and paddlefish as a model for the branch leading to ray-finned fishes, the researchers found that electrosensors develop in precisely the same pattern from the same embryonic tissue
in the developing skin, confirming that this is an ancient sensory system.
