About Stem Cell Research


Stem cells are undifferentiated cells that can develop into specialized tissue types. Researchers are investigating how to isolate and culture them, and control their differentiation, in the hope that they can be used to treat and understand a variety of diseases.

Stem cells can be derived from a number of cellular sources: adult, fetal, and placental tissues; umbilical cord blood; and embryos. Stem cells from these different sources have different properties.

Adult stem cells can be obtained from the bodies of adults and children, and until recently considered multipotent, which means that particular adult stem cells can develop into specific tissue types. Adult stem cells have been used in therapies such as bone marrow transplants for years.

Embryonic stem cells are found in early embryos. They are pluripotent, which means they can develop into all tissue types and be cultured as stem cell "lines." No therapies have been developed from human embryonic stem cells, which were first isolated in 1998.

In recent years, new methods of cellular reprogramming have enabled the derivation of so-called induced pluripitent stem (iPS) cells, which seem to have the full powers of embryonic stem cells but are from adult body cells.

Human embryonic stem cell research is controversial because it destroys embryos. Most investigations use embryos created but not used for in vitro fertilization (IVF) treatment. Some scientists have worked to derive human embryonic stem cells using a cloning technique called research cloning, which raises a separate set of troubling questions.



Guest Post: A Look Inside a Stem Cell Clinic Infomercial Eventby David BrafmanKnoepfler Lab Stem Cell BlogApril 29th, 2015Over the past several years there has been a proliferation of so-called stem cell ‘clinics’, which promise patients miraculous therapies often for currently incurable diseases and disorders.
Seeking Your Input: Survey on Egg Retrievalby Gina Maranto, Biopolitical Times guest contributorApril 22nd, 2015We are surveying women’s knowledge and attitudes toward egg retrieval to yield critical insights into how best to frame health information intended to enable women to make informed choices.
Hype, Money and Stem Cellsby Pete ShanksBiopolitical TimesApril 9th, 2015Michael Hiltzik of the Los Angeles Times used newly published research to write a scathing article largely focused on the California Institute for Regenerative Medicine.
New Study: Stem Cell Field is Infected with Hypeby Michael HiltzikLos Angeles TimesMarch 31st, 2015Stem cell researchers often ply journalists with "unrealistic timelines" for the development of stem cell therapies, and journalists often swallow these claims uncritically.
New DNA Tech: Creating Unicorns and Curing Cancer for Real?by David Ewing DuncanThe Daily BeastMarch 30th, 2015We have the earth-shattering technology in our hands—but even its inventors worry about its awesome power to alter our genetic future.
The Price Of Hype: The Public Now Has Unrealistic Timelines For Scienceby Hank CampbellScience 2.0March 11th, 2015Today, people think stem cell therapies already exist. It's not science journalists and bloggers framing this for political gain. The culprits are scientists playing up their research.
A U.S. Cloning Pioneer’s Startling New Partnershipsby Cynthia FoxBioScience TechnologyMarch 3rd, 2015In a move that stunned the stem cell field, the first researcher to create cloned human cells—and to derive embryonic stem cells from them—has teamed with a man who once made a fraudulent claim to do the same.
'Manufactured' Babies of Same-Sex Parents May Soon Be Reality[Quotes CGS's Marcy Darnovsky]by Beth GreenfieldYahoo ParentingFebruary 26th, 2015Some say it will allow same-sex couples to “manufacture” biological babies using embryonic stem cells.
How Much Do Stem Cell Treatments Really Cost?by Paul KnoepflerKnoepfler Lab Stem Cell BlogFebruary 22nd, 2015Part of the way that clinics cut corners to boost their profits is by not following FDA regulations, putting patients in danger.
