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.
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]
Former Senator Frist also supports stem cell research, despite having initially supported past restrictions on embryonic stem cell research. 2008 V.P. candidate Palin opposed embryonic stem cell research, which she said causes the destruction of life, thus this research is inconsistent with her pro-life position and she does not support it.

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 ...
In 1998, Thomson's Lab was the first to report the successful isolation of human embryonic stem cells. On November 6, 1998, Science published this research in an article titled "Embryonic Stem Cell Lines Derived from Human Blastocysts", results which Science later featured in its “Scientific Breakthrough of the Year” article, 1999.

The Food and Drug Administration (FDA) approved the first clinical trial in the United States involving human embryonic stem cells on January 23, 2009. Geron Corporation, a biotechnology firm located in Menlo Park, California, originally planned to enroll ten patients with spinal cord injuries to participate in the trial.
Hwang's team reported another successful cloning of human cells in the 17 June 2005 issue of Science, in this case, embryonic stem cells derived from skin cells. [27] Their study claimed the creation of 11 different stem cell lines that were the exact match of DNA in people having a variety of diseases. The experiment used 185 eggs from 18 ...
A blastoid is an embryoid, [1] a stem cell-based embryo model which, morphologically and transcriptionally resembles the early, pre-implantation, mammalian conceptus, called the blastocyst. The first blastoids were created by the Nicolas Rivron laboratory [ 2 ] [ 3 ] by combining mouse embryonic stem cells and mouse trophoblast stem cells.
