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.



Top 5 Challenges for SCNT Cloned Human Embryonic Stem Cellsby Paul KnoepflerKnoepfler Lab Stem Cell BlogApril 21st, 2014A new advance in somatic cell nuclear transfer-based therapeutic cloning of human embryonic stem cells is important because it showed it could be done using adult cells. However, key challenges and concerns remain.

New Hope for Embattled STAP Cell Researchers?by Monte MorinLos Angeles TimesApril 1st, 2014Just hours after Japanese investigators announced findings of fabrication and misconduct in a highly criticized "acid bath" stem cell study, scientists in Hong Kong said they had partly succeeded in reproducing the controversial experiment.

One Author of a Startling Stem Cell Study Calls for Its Retractionby Hiroko TabuchiThe New York TimesMarch 10th, 2014Saying he is no longer sure of his team’s conclusions, an author of a study that claimed to have discovered a simple new way to make stem cells has called for it to be retracted.
Critiquing the California Stem Cell Story: 'Continuums' vs. Curesby David JensenCalifornia Stem Cell ReportMarch 10th, 2014What cures has the California stem cell agency produced, as was promised during the 2004 ballot campaign that created the state program?
Efforts to Repeat Controversial Stem Cell Technique Intensifyby Carolyn Y. JohnsonThe Boston GlobeMarch 6th, 2014In an effort to bring clarity to one of the most controversial and confusing scientific findings in recent memory, three Japanese scientists have released a detailed protocol explaining step by step how to create stem cells with a simple acid bath.
