Immune molecule that plays a powerful role in avoiding organ rejection identified (6/21/2008)

When a mouse's immune system is deciding whether to reject a skin graft, one powerful member of a molecular family designed to provoke such a response can effectively reduce the visibility of the mouse's own cells and help the graft survive ...> Full Article

First-Ever Recording of Blood Vessel Development During the Formation of an Organ (6/8/2008)

A new microscope system that can take 3-D pictures of an embryonic mouse organ over 24 to 48 hours has shown researchers the first glimpse of the formation of blood vessels during development. ...> Full Article

From Stem Cells To Organs: The Bioengineering Challenge (2/17/2008)

For more than a decade, Peter Zandstra has been working at the University of Toronto to rev up the production of stem cells and their descendants. The raw materials are adult blood stem cells and embryonic stem cells. The end products are blood and heart cells -- lots of them. Enough mouse heart cells that they form beating tissue. ...> Full Article

Study probes stance on animal-to-human transplants (1/27/2008)

A study has found people who would benefit from animal-to-human transplants (xenotransplants), baulk at the idea of receiving organs from animals otherwise destined for their dinner plate. ...> Full Article

Cell printing pioneer shortlisted for major prize (1/25/2008)

A professor who developed technology that allows tailor-made tissues and bones to be grown has been shortlisted for a major international prize that recognises world changing ideas. ...> Full Article

Enzyme Mutation Disrupts Organ Growth (11/29/2007)

The cellular mechanism that turns DNA into all of the thousands of proteins that make up a human body is itself both intricate and interesting. A key player in the process--called transcription--is the enzyme RNA polymerase III. A new study reports that a mutation of this enzyme prevents cell division, but surprisingly, only affects the development of specific organs. It may also have a therapeutic application against cancer. ...> Full Article

Breakthrough in Organ Rejection Diagnosis Examines Gene Behavior (11/25/2007)

New Research describes a revolutionary technique for more clearly identifying the possibility of organ rejection in kidney transplants. The technique, which uses a microarray or "Gene Chip," a process of examining DNA sequences, defines how major causes of organ disease leading to rejection share similar disturbances in gene behavior. The study is the first to show how gene sets, as opposed to single genes, can be used for diagnosis of rejection in individual patients, and offers new insight into the mechanisms of these gene changes. ...> Full Article

Stem Cells Derived from Adult Testes Produce Wide Range of Tissue Types for Therapeutic Organ Regeneration (9/20/2007)

After a decade of research, Howard Hughes Medical Institute scientists have succeeded in reprogramming adult stem cells from the testes of male mice into functional blood vessels and contractile cardiac tissue. The research offers a promising new source of stem cells for use in organ regeneration studies. ...> Full Article

Nanotechnology May Be Used to Regenerate Tissues And Organs (5/3/2007)
