Summary
This study examines the moral justification for using discarded human embryos in human embryonic stem cell (hESC) research. The paper argues that the common justification for using these embryos is unsound, impacting public policy debates.
Area of Science:
- Bioethics
- Stem Cell Research
- Embryology
Background:
- The use of human embryos in research is a contentious issue.
- Many believe discarded embryos from fertility treatments can be ethically used in human embryonic stem cell (hESC) research.
- This view is often proposed as a compromise in public funding debates.
Purpose of the Study:
- To critically evaluate the most plausible argument justifying the use of discarded embryos in hESC research.
- To determine if this argument remains sound regardless of the moral status attributed to embryos.
- To discuss the policy implications of this ethical argument's potential unsoundness.
Main Methods:
- Philosophical analysis of ethical arguments.
- Examination of the concept of moral status in relation to human embryos.
- Review of policy implications related to hESC research funding.
Main Results:
- The primary argument for morally justifying the use of discarded embryos in hESC research is found to be unsound.
- This conclusion holds irrespective of varying interpretations of embryo moral status.
- The ethical basis for public policy supporting such research is undermined.
Conclusions:
- The ethical justification for using discarded embryos in hESC research is flawed.
- This finding has significant implications for public policy and funding decisions regarding hESC research.
- Rethinking the ethical framework for embryo research is necessary.

Embryonic Stem Cells
Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Embryonic Stem Cells
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.
Stem Cell Culture
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
Zygotic Development And Stem Cell Formation
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
