The direction of research and development of stem cell production mouse and human embryo models.

As early as the 1980s, there was a debate in the UK about whether human embryo models should be allowed.
from a medical point of view, human embryo in vitro research will undoubtedly benefit human beings, but from an ethical point of view, is the embryo equivalent to the existence of the truth of the human person? Should it have the same moral status as it does? The two sides could not reach an agreement on the argument.
therefore, the "14-day period" principle was born, that is, human embryos must not be cultured in vitro for more than 14 days.
this important rule continues to this day.
now, there are repeated breakthroughs in embryo culture technology, calling for a rethink of the existing framework in order to find the best solution in the interests of science, society and potential medical interests.
using stem cells in the laboratory to make models of mouse and human embryos are moving forward rapidly, bringing profound legal and ethical issues.
in view of this, the British journal Nature recently published an opinion piece, calling on the international community to discuss the direction of this fast-growing field of research.
in their comments, scientists at the Hublerch Institute in the Netherlands and Jackson Labs in the United States agreed that there must be an open and transparent discussion about the legal status of human stem cell-derived embryo models and the application of such research in order to help countries develop policies and regulations. "Effective communication with the public is key to ensuring prudent progress to promising research methods,"
wrote.
" Over the past 18 months, researchers have developed mouse models that contain similar ovoid sacs and placental tissue.
comment notes that it is not expected to be far from being used to make similar human models using human stem cells.
such models are expected to improve the effectiveness and safety of in vitro fertilization (IVF) and promote the prevention and treatment of developmental disorders.
article, scientists raise several issues that need to be discussed publicly, including whether the lab-like entities should be treated as human embryos now or in the future, and how limits should be set for the cultivation of complete human embryos.
they urged funding agencies and the scientific and medical community to take the lead in the discussion.
can treat embryonic-like entities as human embryos has been highly controversial. some scholars
argue that although human embryos have the potential to develop into complete human beings, there is still a difference between human embryos and those who exist as facts, while the opposition is that human embryos should be regarded as having the ability to develop adults from the very beginning of fertilization.
published this article is a review in the journal Nature, rather than a peer-reviewed nature research paper, an authoritative review of scientific research and its impact.
