Because human embryonic stem cells are extracted from human embryos, several questions and issues have been raised about the ethics of embryonic stem cell research the national institutes of health created guidelines for human stem cell research in 2009. John d gearhart is a renowned american developmental geneticist best known for leading the johns hopkins university research team that first identified and isolated human pluripotent stem cells from human primordial germ cells, the precursors of fully differentiated germ cells born in.
What are embryonic stem cells embryonic stem cells are derived from embryos at a developmental stage before the time that implantation would normally occur in the uterus fertilization normally occurs in the oviduct, and during the next few days, a series of cleavage divisions occur as the embryo. Abstract the use of human embryos for research on embryonic stem (es) cells is currently high on the ethical and political agenda in many countries. Stem cells are cells found in all multi-cellular organisms they were isolated in mice in 1981, and in humans in 1998 in humans there are many types of stem cells, each with varying levels of potency. Abstract human blastocyst-derived, pluripotent cell lines are described that have normal karyotypes, express high levels of telomerase activity, and express cell surface markers that characterize primate embryonic stem cells but do not characterize other early lineages.

Stem cells are the cellular putty from which all tissues of the body are made ever since human embryonic stem cells were first grown in the lab, researchers have dreamed of using them to repair. In november 1998 the first published research paper reported that stem cells could be taken from human embryos subsequent research led to the ability to maintain undifferentiated stem cell lines (pluripotent cells) and techniques for differentiating them into cells specific to various tissues and organs.
Stem cell research has sparked controversy and heated debate since the first human stem cell line was derived in 1998 too frequently these debates devolve to simple judgments—good or bad, life-saving medicine or bioethical nightmare, symbol of human ingenuity or our fall from grace—ignoring the people affected.

Also, research has been underway for about 25 years more than embryonic stem cells, so that they are now routinely used in medical procedures in comparison, embryonic stem cell reasearch are still at the initial experimental trial state. Stem cell research has long been a much-debated and highly-controversial scientific field while there is no apparent controversy with regards to who discovered stem cells, many scientists through the years have contributed to the development of the study that it would appear difficult to credit a single person for the discovery.
