UPDATE ON HUMAN CLONING AND FETUS FARMS
This is an update from the Federal Legislation
Department at National Right to Life in Washington, D.C., 202-626-8820,
Legfederal@aol.com, issued on September 21, 2005.
It now appears that consideration of various bills
dealing with embryonic stem cell research, human cloning, and related
issues in the U.S. Senate will be delayed, at least until October 2005
and perhaps longer, due in part to preoccupation with legislation
related to Hurricane Katrina, and the two Supreme Court vacancies. The
issue also continues to percolate in a number of state legislatures.
This update provides you with several new resources on these issues, as
follows:
1. In the past, we have pointed out how the research
use of so-called "leftover" human embryos, created by in vitro
fertilization, is only a brief stepping stone towards the use of cloning
to create human embryos for the sole purpose of using them in research
and therapies (so-called "therapeutic cloning"). While advocates of
"therapeutic cloning" initially claimed that they would grow human
embryos "only" to 14 days of development, we asserted that this
limitation, too, was merely a temporary political expedient and would
quickly be abandoned.
In July, the on-line magazine Slate published a
five-part series, written by its national correspondent, William Saletan,
titled "The Organ Factory: The case for harvesting older human
embryos," which is available here
in Microsoft Word format. (The series can also be read at the Slate
website
here.)
Mr. Saletan presents evidence that growing human
embryos to the eight-week point will become technically feasible in the
not-distant future, and would provide tissues of more medical value than
cells obtained from 14-day-old embryos. Why not do it then?, Mr. Saletan asks.
2. What Mr. Saletan describes is what we have
referred to as "fetus farming," although he does not use that term.
Cloning researchers are rapidly progressing down the road towards fetus
farms. In the June 2005 issue of "Cloning and Stem Cells," a technical
journal, Dr. Robert Lanza and other researchers at Advanced Cell
Technology (Worcester, MA) reported that they created cloned cow
fetuses, grew them in utero in adult cows to four months (which is
equivalent to four months in a human pregnancy), aborted the fetal cows,
obtained the liver tissue cells that they desired, and transplanted
those cells into adult cows. The authors reported this exercise as an
advance in “therapeutic cloning” (the first two words in their
summary). Although the authors claimed a degree of success, they
observed, “Improvement in engraftment may be anticipated if the number
of stem cells transplanted were to be increased, either by utilizing
older fetuses . . .” (See
“Long-Term Bovine Hematopoietic Engraftment with Clone-Derived Stem Cells,"
Cloning and Stem Cells, June 2005.)
We suggest that ACT is not spending money on this
research in the hope of developing a treatment for liver disease in
cows.
3. On July 27, 2005, Senator Dianne Feinstein (D-Ca.) and others
introduced S. 1520, a new version of "clone-and-kill" legislation.
Unlike the previous versions, S. 1520 does not contain the 14-day
"deadline" for killing the cloned human embryos.
NRLC's on-line factsheet, "Human
Cloning Legislation in Congress: Misconceptions and Realities,"
contains the most up-to-date information on cloning-related legislation
in Congress, including the evolution of the "clone-and-kill" bills.
Most of the information in the factsheet is also readily applicable to
cloning-related debates in state legislatures.
4. In order to make large-scale human "fetus
farming" feasible, some sort of "artificial womb" would be necessary.
In this field, too, researchers seem to be advancing rapidly. A new
NRLC factsheet, "Artificial
Wombs: From Embryo Farms to Fetus Farms," contains an eye-opening
collection of excerpts from different sources on this subject.
5. Following the disappointing July 29 announcement
by Sen. Bill Frist (R-Tn.) that he will support the bill (H.R. 810) to
provide federal funds for certain research that requires the killing of
human embryos, medical journalist Michael Fumento wrote a worthwhile
column titled "On Embryonic Stem Cells, Frist Backs A Loser," which you
can read
here.

topics can be accessed in the "Human Embryos" section of the NRLC
website,
