Thus, embryonic stem cells are likely to be easier to isolate and grow ex vivo than adult stem cells. [36] Embryonic stem cells divide more rapidly than adult stem cells, potentially making it easier to generate large numbers of cells for therapeutic means. In contrast, adult stem cell might not divide fast enough to offer immediate treatment. [36]
Embryonic stem cells is one of the sources that are being considered for the use of tissue engineering. [19] The use of human embryonic stem cells have opened many new possibilities for tissue engineering, however, there are many hurdles that must be made before human embryonic stem cell can even be utilized.
The use of embryonic stem cells has also been applied to tendon repair. The embryonic stem cells were shown to have a better survival rate in the tendon as well as better migrating capabilities to reach all areas of damaged tendon. The overall repair quality was also higher, with better tendon architecture and collagen formed.
Some stem cells form tumors after transplantation; [106] pluripotency is linked to tumor formation especially in embryonic stem cells, fetal proper stem cells, induced pluripotent stem cells. Fetal proper stem cells form tumors despite multipotency. [107] Ethical concerns are also raised about the practice of using or researching embryonic stem ...
However, since the generation of embryonic stem cells involves destruction (or at least manipulation) [4] of the pre-implantation stage embryo, there has been much controversy surrounding their use. Patient-matched embryonic stem cell lines can now be derived using somatic cell nuclear transfer (SCNT). [citation needed]
As opposed to mesenchymal stem cells, embryonic-like stem cells are not abundant in the amniotic fluid, making up less than 1% of amniocentesis samples. Embryonic-like stem cells were originally identified using markers common to embryonic stem cells such as nuclear Oct4, CD34, vimentin, alkaline phosphatase, stem cell factor and c-Kit. However ...
In September 2020, Scalise co-signed a letter by Mississippi Sen. Roger Wicker calling for an end to taxpayer funded embryonic stem cell research at the National Institutes of Health, but the ...
A stem cell line is a group of stem cells that is cultured in vitro and can be propagated indefinitely. Stem cell lines are derived from either animal or human tissues and come from one of three sources: embryonic stem cells, adult stem cells, or induced pluripotent stem cells. They are commonly used in research and regenerative medicine.
