Senate Dems reject ban on certain types of human-animal hybrid experiments

A party line vote saw 48 Republicans supporting the measure and 49 Democrats rejecting it. 含义. 汤姆·提利斯, R-N.C。, 乔·曼钦, 德瓦, and Marsha Blackburn, R-Tenn。, didn’t vote.

Proposed this week, the Endless Frontier Act also contained language barring the transfer of a human embryo to a non-human womb and vice versa.

We shouldn’t need to clarify in law that creating animal-human hybrids or ‘chimeras’ is ethically unthinkable, but sadly the need for that very clear distinction has arrived,” 说森. 詹姆斯·兰克福德, R-Okla。, who co-sponsored the bill with Sens. Mike Braun, 果皮。, and Steve Daines, R-Mont.


Braun said: “Human life is distinct and sacred, and research that creates an animal-human hybrid or transfers a human embryo into an animal womb or vice versa should be completely prohibited, and engaging in such unethical experiments should be a crime.

The legislation would impose penalties as high as $ 1 million orthe amount equal to twice the amount of the gross pecuniary gain.It also provided for up to 10 入狱多年.

The bill was intended as a check on the National Institutes of Health (NIH) potentially lifting its moratorium on research utilizing chimeras.

在星期三, the International Society for Stem Cell Research released guidance backing chimeric research.

Chimeric embryo and in utero research … should proceed for the minimum time necessary to achieve the scientific aim,” the organization’s guidelines read.

This research must proceed incrementally, stopping at well-defined timepoints to assess the degree and scope of chimerism during development before proceeding to full gestation, if full gestation is among the well-justified goals of the research. To avoid unpredictable and widespread chimerism, researchers should endeavor to use targeted chimerism strategies to limit chimerism to a particular organ system or region of the gestating chimeric animal.

Thursday’s vote came against the backdrop of a growing debate about the use of fetal tissue in scientific research.

本月初, Pennsylvania’s legislature held hearings discussing, 部分地, the University of Pittsburgh’s fetal tissue practices. Amid a raging debate about fetal cell lines and COVID-19 vaccines, a Pitt study gained attention for grafting fetal scalps onto mice.
