Human pluripotent stem cells are valued for their potential to form numerous specialized cells and for their longevity. In the US, where a portion of the population is opposed to destruction of human embryos to obtain stem cells, what avenues are open to scientists for obtaining pluripotent cells that do not offend the moral sensibilities of a significant number of citizens? It is this question that the official position paper, or white paper, "Alternative Sources of Human Pluripotent Stem Cells," published in May 2005 by the President's Council on Bioethics under the chairmanship of Leon Kass, seeks to answer. Three experts external to the council, Andrew Fire from the Stanford University School of Medicine, Markus Grompe of the Oregon Health and Science University, and Janet Rossant from the Samuel Lunenfeld Research Institute in Toronto, also reviewed the white paper prior to publication.

Matthew Kaufman was a professor of anatomy at the University of Edinburgh, in Edinburgh, UK, who specialized in mouse anatomy, development, and embryology during the late twentieth century. According to the The Herald, he was the first, alongside his colleague Martin Evans, to isolate and culture embryonic stem cells. Researchers initially called those cells Evans-Kaufman cells. In 1992, Kaufman published The Atlas of Mouse Development, a book that included photographs of mice development and mice organs over time. Kaufman also wrote books about UK medical history, phrenology, or the study of craniums as an indicator of character or mental ability, and medical teaching in the eighteenth and nineteenth centuries. Kaufman’s anatomical records and experiments in mouse development contributed to genetic engineering, embryology, and anatomy.

Henry Morgentaler was a physician who performed abortions, acted as a reproductive rights activist, and advocated for legal access to abortions in Canada during the twentieth century. In 1969, he opened his first abortion clinic in Canada and participated in the legal/court case of R v. Morgentaler (1988), which led Canada to decriminalize abortion. Morgentaler helped establish legal access to abortions for women in Canada and advocated for the protection of women's reproductive choices under the law.

Where Are My Children? is an anti-abortion silent film released in the United States on 16 April 1916. The film was directed by Lois Weber and Phillips Smalley and produced by Universal Film Manufacturing Company/Lois Weber Productions in Universal City, California. In the film, Weber tells a story of an attorney who wants to have children and raise a family, but his wife chooses to abort her pregnancies, fearing that having children will ruin her social activities. In the early 1900s, information about contraception was not freely available or legal to obtain. Physicians were allowed to distribute contraceptives only if the woman would be put in a life-threatening circumstance were she to get pregnant. In the film, Weber encourages contraceptives as a means of family planning, but advocates against abortions. Where Are My Children? is one of the first films to discuss birth control and family planning, and it is among the first to push against motion picture censorship of contraception and family planning in cinema.

Margaret Higgins Sanger advocated for birth control in the United States and Europe during the late nineteenth and early twentieth centuries. Although people used contraceptives prior to the twentieth century, in the US the 1873 Comstock Act made the distribution of information relating to the use of contraceptives illegal, and similar state-level Comstock laws also classified discussion and dissemination of contraceptives as illegal. Sanger helped to repeal the Comstock Act and similar laws so that women could legally use contraceptives to control their fertility and the sizes of their families. In 1916, Sanger opened the first birth control clinic in the US in New York City, New York. Later in life, Sanger formed several advocacy organizations that promoted access to contraception, including the Planned Parenthood Federation of America. Sanger's advocacy increased women's access to contraception and helped change the United States' social and legal perceptions of birth control.

Margaret Goldwater advocated for birth control and reproductive rights in the United States during the twentieth century. Goldwater was a socialite and philanthropist and was married to Barry Goldwater, US Senator from Arizona. She spent much of her life working to further the women's reproductive rights movement, which sought to expand women's legal, social, and physical access to reproductive healthcare, including contraception and abortions. Goldwater, with guidance from birth control activist Margaret Sanger, helped establish the second birth control clinic in Arizona, the Mother's Health Clinic in Phoenix, Arizona. She conducted large fundraising events and authored articles in local newspapers on the need for contraceptives and family planning. Goldwater's advocacy helped launch and sustain The Mother's Health Clinic, which became the largest provider of women's reproductive healthcare in Arizona, and it later became Planned Parenthood of Central and Northern Arizona.

In the twentieth and early twenty-first centuries, Gail Roberta Martin specialized in biochemistry and embryology, more specifically cellular communication and the development of organs. In 1981, she named any cell taken from inside a human embryo at the blastocyst stage an “embryonic stem cell”. During development, an embryo goes through the blastocyst stage just before it implants in the uterus. Embryonic stem cells are useful for experiments because they are self-renewing and able to develop into almost any cell type in the body. Martin later identified a key chemical component in limb development and continues to study embryogenesis, or the growth of embryos over time. Martin’s work on embryonic stem cells has allowed scientists to further research and treat human diseases, and her study of how organs form has helped scientists learn about the healthy growth of embryos.

The Chicago Women’s Liberation Union, hereafter Union or CWLU, was a feminist union that operated in Chicago, Illinois, from 1969 to 1977 and was the first and largest union, at the time of its operation, focused on women’s issues. The Union organized women with the self-proclaimed collective goal of achieving liberation from sexism and inequality. Within the larger CWLU, smaller groups and chapters formed to address issues such as abortion, rape, child care, and reproductive health, among others. During CWLU’s eight years of operation, the activists circulated petitions, held demonstrations, and visited high schools to raise public awareness of women’s issues. The CWLU created educational opportunities for women in response to apparent sexism in the US and connected them to social groups to further the women’s liberation movement and women’s reproductive health awareness in the United States.

Charles Knowlton was a physician and author who advocated for increased access to information about reproduction in the nineteenth century in the US. Throughout his early medical education, Knowlton was particularly interested in anatomy and on several instances robbed graves for bodies to dissect. In 1832, Knowlton authored The Fruits of Philosophy, a pamphlet that contained detailed descriptions of the reproductive organs and information on conception and methods to control reproduction. Knowlton circulated his work among his patients until it was republished in Boston, Massachusetts, in 1832. For publishing a book on sex and methods of birth control, Knowlton was convicted of breaking obscenity laws, which prevented the transmission of obscene materials. After his death, social activists Charles Bradlaugh and Annie Besant republished his work in London, England. Knowlton’s writing about sex and birth control allowed individuals to understand and take control of their reproduction and initiated a public discussion about obscenity laws.
