• Human stem cell research
Embryonic
Adult (somatic):
Undifferentiated cells, found among
differentiated cells in a tissue or organ that can
renew themselves and can differentiate to yield
some or all of the major specialized cell types
of the tissue or organ.
Primary role: to maintain and repair the tissue in
which they are found.STEM CELL RESEARCH

• Ethics
Discussion of the bioethics of human stem
cell research has transitioned from
controversies over the source of human
embryonic stem cells to concerns about the
ethical use of stem cells in basic and clinical
research.International Stem Cell Research

• November 1998
Dr. James A. Thompson, a biologist at the
University of Wisconsin, first reported the
isolation of human embryonic stem cells
(hESCs).
Scientists hoped to find ways of using hESCs to
repair damaged tissue.
Until 2001, no public funding was ever provided
for hESC research in the U.S.
President Bush: “I oppose federal funding for
SC research that involves destroying living
human embryos.”United States
• May 24, 2005
The House of Representatives passed a
bill to expand federal financing for
embryonic stem cell research, defying a
veto threat from President Bush.
An identical bill has board bipartisan
support in the U.S. Senate.United States
• The Stem Cell Research Enhancement Act
(SCREA) of 2005
Would ease current restrictions on
federal funding for stem cell research by
allowing the Secretary of Health and
Human Services to conduct and support
research on stem cells, regardless of the
date on which they derived from a
human embryo.United States
• HR-2520, the “Stem Cell Therapeutic &
Research Act of 2005” - Passed virtually
unanimous decision by the House of
Representatives.
The Bill amended the Public Health Service Act
to establish a National Cord Blood Stem Cell
Bank Network to:
Prepare, store and distribute human umbilical
cord blood stem cells for the treatment of
patients and to support peer-reviewed
research using such cells.
$19.4 M appropriation to collect
cryopreserved cord blood SC units with
extended funding over five years.President Obama signs the executive order on stem
cell policy at the White House (March 09, 2009)
Today, with the Executive Order I am about to sign, we will bring the change that
so many scientists and researchers; doctors and innovators; patients and loved
ones have hoped for, and fought for, these past eight years: we will lift the ban on
federal funding for promising embryonic stem cell research. We will vigorously
support scientists who pursue this research. And we will aim for America to lead
the world in the discoveries it one day may yield.United States
• Under the auspices of the Obama
administration, the NIH expands federal
funding for stem cell lines that meet certain
ethical requirements if:
The embryo was discarded after IVF.
Informed consent was obtained from the
donors.
The couple does not receive compensation
(neither financial nor medical benefits) or are
concerned or threatened.United States • Older stem cell lines created in the spirit the new regulations will be considered for federal funding, whereas embryos created solely for research purposes will be excluded.
United States
• NIH guidelines
April 23, 2009: NIH published draft
guidelines allowing funding for research on
SCs derived from donated embryos leftover
from fertility treatment, provided that
certain conditions be met, such as the
voluntary informed consent of donors.
NIH continues to fund research on adult SCs
and induced pluripotent SCs.Australia
• Research involving SC is managed largely by
the Australian Stem Cell Center (ASCC) based
at Monach University in Melbourne.
The ASCC has links with many universities
around Australia and around the world.
• Bio21 at the University of Melbourne
An Australian research base for Cygenics Ltd
who, through their subsidiary Cordlife Pty Ltd,
have moved some of their research from the
USA to Australia.Australia
• Therapeutic focus:
Hematopoiesis
Cardiac regeneration
Respiratory diseases
• Therapeutic cloning is permitted.
• The main technology platforms used are:
Embryonic SC (obtained from surplus IVF)
Adult SCs
Tissue repair and immune modulationAustralia
• Funding
Australian SC Center who in-turn holds
funding rounds.
Source of funding: The Australian
Government and the State Government of
Victoria provide the majority of funding for
the ASCC while a small amount comes from
the commercial affiliations the ASCC
maintain.Brazil
• March 2005 Bill
Authorizes the use of SC in research and
therapy.
It allows the use of SCs up to five days old
that cannot be used further in IVF
process
Also allows unused embryos that have
been frozen for at least 3 yrs.Brazil • The use of cloning techniques in order to obtain embryos is prohibited, whether the objective is therapeutic cloning or human cloning. • Genetic engineering in embryos, eggs, and sperm is not allowed. • The University of Sao Paulo has successfully tested the use of SCs as a treatment for diabetes.
Brazil • Is still at an early stage regarding human SCs, but quite advanced in veterinary SCs, which are important models for research on humans. • In order to carry out research with SCs, research groups must submit their projects to their institution's ethics committee as well as to CONEP (National Council for Ethics in Research).
Canada
• SC research is funded by a mix of the
Canadian Institutes of Health Research
The Canadian Stem Cell Network
Genome Canada
NSERC (the Natural Sciences &
Engineering Research Council)
National Cancer Institute
Provincial governments
US NIHCanada
• ACT: Canadian Federal Government,
March 2004
Banning human cloning for reproductive
or therapeutic purposes.
However, the Assisted Human
Reproductive Act allows for Canadians to
derive new human SC lines from embryos
left over after fertility treatment.
The agency was established in 2006.Canada • A Stem Cell Oversight Committee (SCOC) has been established by the Canadian research councils to conduct ethical review of all human pluripotent SC research proposals recommended for approval by their scientific peer review panels.
Canada
• CARE-NET
Brings together researchers from four
Canadian cities to study the use of adult
SCs as repair material for damaged
hearts, lungs and blood vessels.
• Canada has had a long history in SC
research.
Has currently more than 100 senior
scientists working on SC.China
• Growing interest in SC research (the
government initiative).
• Chinese biotechnologies in general are
now competing on innovation with their
Western counterparts.
• Well-funded teams in China’s major
cities, some connected to large hospitals
SCs from adult, fetal and embryonic
sources.China • The country faces fewer moral or public objections to the use of embryonic SCs than Western nations. • Production of new human embryonic SC lines are legal, as is therapeutic cloning. • China’s Ministry of Sciences & Technology (MoST) funds the bulk of the research directly.
China
• SC research in China is regulated by only
one guideline, which was jointly issued
by the Ministry of Science & Technology
and the Ministry of Health in December
2003.
Each local institution has a review
committee of specialists of wide ranges.
The committees are directly responsible for
the authorization and surveillance of hESC
research.China
• SC research guidelines
Prohibited:
Reproductive cloning
Transfer of an embryo into the uterus of a
woman or animal
Generation of chimeric human embryos
• However, there is “regional” lack of
regulated stem cell procedure.China
• Most of China’s top university SC labs
and centers have spun-off companies to
commercialize their research.
A typical example is SinoCells, a span-out
from the Peking University’s SC Research
Center, which aims to develop
cryopreservation methods for SCs.
• Potential for a “cloning superpower”
• Therapeutic cloning permitted.France
• SC research strengths

announcement of establishing
mechanisms by which ESCs differentiate
to muscle cells.

(Hopital Necker).France • A Bioethics Act permits research on the embryo. • Both therapeutic and reproductive cloning are banned under the Act. • Licensing of embryo research will be the responsibility of Agence de Biomedicine. The Agency was established in May 2005.
France • The French Academie des Sciences and Academie de Medicine both favor authorization of therapeutic cloning due to its potential in finding treatments for new diseases. • There are growing signs of openness to discuss the issue and increasing political support for authorization of therapeutic cloning.
India • Many Ms of $ are spent on SC research in India in the past years. • The Department of Biotechnology under Ministry of Science & Technology is the nodal funding agency for supporting the SC R & D programs. • Research is promoted for therapeutics applications using adult and embryonic SCs.
India
• Absence of laws specific to SC Research
Government of India has drawn up a plan to
effectively review and monitor the way stem cell
research being conducted in the country.
• Institutions engaged in SC research (SCs to
regenerate nerve, heart and adult muscle cells, and
repair damaged bone tissue):
L.V. Prasad Eye Institute, Chennai, Christian
Medical College, Vellore, National Brain
Research Center in Delhi.Japan
• Allows scientists to conduct stem cell
research for therapeutic purposes.
• No consensus on formal guidelines
• November 2007
Japanese researchers collaborated with
American scientists reprogrammed
human skin cells to behave like
embryonic stem cells.Japan • In general, slow development of the regulatory framework. • Continues to receive significant amount of public funding. • Despite lack of a transparent regulatory framework, few human ESC lines have derived at Kyoto University using frozen embryos.
Japan
• On July 23, 2004, Japan’s Council for
Science and Technology Policy, the
government top science and technology
policy body, approved the final report of
its Bioethics Expert Panel on human
embryo and SC research.
The report recommended a change in
Japanese policy to allow the creation on
human embryos using therapeutic
cloning techniques for SC research.United Kingdom • In January 2001, Parliament agreed to regulations to allow research for therapeutic purposes on cells derived from human embryos. • As part of the agreement, a House of Lords Select Committee on Stem Cell Research was formed to examine the issue in more detail.
United Kingdom
• Regulatory issues
The rapid pace of advances in SC research
has led to concerns that developments
were moving too fast for the regulatory
process to keep up!
Among the key regulatory issues by the
Lords SC Res Committee were the
inadequacy of existing legislation &
regulations and the possible need for
further regulation to take recent
developments into account.United Kingdom
• The House of Lords SC Committee
Weighted the ethical arguments carefully.
While respecting the views of those who
regarded any research involving the
destruction of a human embryo wrong, it
concluded that in light of the current law
and social attitudes, it was “not
persuaded that all research on early
human embryos should be prohibited.”United Kingdom
• The 14 Day Limit – The Warnock Committee
Chose a 14 day limit for research on human
embryos because this is a the point at which
the precursor to what will eventually develop
into the nervous system becomes apparent.
Although this is a somewhat arbitrary, the Lords
SC Res Committee noted that it seemed to have
been widely accepted in practice, and
recommended that 14 days “should remain the
limit for research on early embryos.”United Kingdom
• UK is considered to be a world leader in
its advancement of hESC research.
Employs a more progressive approach and
utilizes an extremely centralized, highly
regulated system for human embryonic
stem cell research.Greater Middle East • Nascent programs Saudi Arabia Qatar • More established programs Iran Israel Turkey
Greater Middle East
• The Fiqh Council of the Muslim World
League in Saudi Arabia
“it is permissible to obtain, grow and use
SCs for therapeutic or permissible scientific
research”
• Islamic Republic of Iran
Fatwa of 2002 – encourages Iranian
scientists to pursue SC research with the
purpose of advancing technology to save
lives.CONCLISION • Scientists and regulatory bodies in many countries are aware of the need for ethical evaluation and specific policies for SC research. • Basic policy/bioethical issues: 1. Scientific and therapeutic relevance 2. Universal standards 3. Regulatory SC procedure
CONCLISION • From a bioethical viewpoint, it is more questionable when dealing with embryos whose cryopreservation should be authorized by the parents which will be used either for a particular use or for donation. • Currently, there is no “global” unanimity on SC research policies, standards and bioethical issues.
CONCLISION
• U.S. vs. U.K.
The United States employs a decentralized
system with little federal regulatory
authority and broad discretion left to states
and private entities.
The United Kingdom utilizes a centralized,
independent body, enabling it to act more
quickly and periodically vis-à-vis SC
research.CONCLISION • Finally, there are countries and regions that lack SC academics, specialists and policymakers to improve the quality of research as well as regulated SC procedure, however, international collaboration might solve the existing issues.
