Stretching the limits: Stem cells in regeneration science

DEVELOPMENTAL DYNAMICS, Issue 12 2008
David L. Stocum
Abstract The focus of regenerative medicine is rebuilding damaged tissues by cell transplantation or implantation of bioartificial tissues. In either case, therapies focus on adult stem cells (ASCs) and embryonic stem cells (ESCs) as cell sources. Here we review four topics based on these two cell sources. The first compares the current performance of ASCs and ESCs as cell transplant therapies and the drawbacks of each. The second explores somatic cell nuclear transfer (SCNT) as a method to derive ESCs that will not be immunorejected. The third topic explores how SCNT and ESC research has led to the ability to derive pluripotent ESCs by the dedifferentiation of adult somatic cells. Lastly, we discuss how research on activation of intrinsic adult stem cells and on somatic cell dedifferentiation can evolve regenerative medicine from a platform consisting of cell transplantation to one that includes the chemical induction of regeneration from the body's own cells at the site of injury.

Embryo Stem Cell Research: Ten Years of Controversy

THE JOURNAL OF LAW, MEDICINE & ETHICS, Issue 2 2010
John A. Robertson
This overview of 10 years of stem cell controversy reviews the moral conflict that has made ESCs so controversial and how this conflict plays itself out in the legal realm, focusing on the constitutional status of efforts to ban ESC research or ESC-derived therapies. It provides a history of the federal funding debate from the Carter to the Obama administrations, and the importance of the Raab memo in authorizing federal funding for research with privately derived ESCs despite the Dickey-Wicker ban on federal funding of embryo research. It also reviews the role that scientists themselves have played in developing regulations for ESC research, the emergence of ESCROs as special review bodies for ESC research, and the thorough consent requirements for donation of IVF embryos to ESC research. With research now transitioning from the lab to the clinic, the article reviews the challenges of ensuring safety and consent in translational research. It concludes with a call for respecting those persons who have to using or working with ESC products and an account of how obtaining stem cells from a person's own cells will alleviate some but not all of the controversy surrounding ESC research.

Patent Policy for Human Embryonic Stem Cell Research in Taiwan

THE JOURNAL OF WORLD INTELLECTUAL PROPERTY, Issue 4 2010
Jerry I.-H.
The potential of human embryonic stem cell (ESC) research could prove to provide immense therapeutic value for illnesses not curable under currently existing therapies. However, human ESC research is controversial as it touches the fundamental value of human life. Taiwan has been aiming to become the biotech hub of Asia-Pacific and is becoming a major player in human ESC research. Whether or not the research results from human ESC are patentable could have a profound impact on the progress in this field. In this article, the science of human ESC research is clarified and tested against the existing murky Taiwan patent standards. In particular, this article distinguishes between therapeutic cloning and reproductive cloning techniques, asks questions about the patentability of totipotent human ESCs and explores the meaning of the word embryo. This article draws comparison with the European practice on ethical standards and concludes that patenting human ESC research might not be so controversial, but Taiwan has to make its patent law clearer in this field to fulfill the country's intended goal.
