A group of researchers in Israel, the United States and other nations have made important advances in the rapidly-expanding field of "regenerative medicine," outlining for the first time connections in genetic regulation that normally prevent birth defects in heart and facial muscles. Some of these problems are surprisingly common — about 1 percent of all people have a congenital heart defect. This basic research will provide a road map to ultimately allow scientists to grow the cell...

Researchers at Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have derived a population of pure lung and thyroid progenitor cells in vitro that successfully mimic the developmental milestones of lung and thyroid tissue formation. The research, which will be published in the April 6 edition of the journal Cell Stem Cell, identifies factors necessary for embryonic stem cells to differentiate into lung progenitor cells and provides key information about how the...

In recent years, a number of controversial claims have been made about the female mammal's egg supply — that it is renewed over her adult lifetime (as opposed to the conventional understanding that she is born with all of her eggs), and that the source of these eggs is stem cells that originate in the bone marrow. Now, Weizmann Institute scientists have disproved one of those claims and pointed in new directions toward resolving the other. Their findings, based on an original method for...

When a sperm fertilizes an egg, each contributes a set of chromosomes to the resulting embryo, which at these very early stages is called a zygote. Early on, zygotic genes are inert, so embryonic development is largely controlled by parental factors. The activation of the zygotic genome therefore represents an important transition toward a more autonomous mode of embryonic development, and has been the subject of much speculation and scrutiny. Now, a new study published by Cell Press on...

Although the body is constantly replacing cells and cell constituents, damage and imperfections accumulate over time. Cleanup efforts are saved for when it really matters. Researchers from the University of Gothenburg, Sweden, are able to show how the body rids itself of damage when it is time to reproduce and create new life. 'I have a daughter. She is made of my cells yet has much less cellular damage than my cells. Why didn't she inherit my cells including the damaged proteins? That's...

For the past decade, researchers have tried to reprogram the identity of all kinds of cell types. Heart cells are one of the most sought-after cells in regenerative medicine because researchers anticipate that they may help to repair injured hearts by replacing lost tissue. Now, researchers at the Perelman School of Medicine at the University of Pennsylvania are the first to demonstrate the direct conversion of a non-heart cell type into a heart cell by RNA transfer. Working on the idea that...

Scientists at the Genome Institute of Singapore (GIS) have recently generated significant single cell expression data crucial for a detailed molecular understanding of mammalian development from fertilization to embryo implantation, a process known as the preimplantation period. The knowledge gained has a direct impact on clinical applications in the areas of regenerative medicine and assisted reproduction. This study, published in Developmental Cell on April 20, 2010, is the first of its...

A new study from the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa suggests that stem cells intentionally break their own DNA as a way of regulating tissue development. The study, published in Proceedings of the National Academy of Science (PNAS), could dramatically change how researchers think about tissue development, stem cells and cancer. Human cells contain 46 strands of DNA that code for all our genes. Certain chemicals and UV light can break these strands into...

The National Institutes of Health has given the University of Pittsburgh $5 million to explore new ways of growing replacement cells from existing tissues. A $2.9 million, five-year grant was presented to Professor Eric Lagasse to support development of a novel concept: using the body's many lymph nodes as sites for growing replacement cells for other tissues and organs. Professor Ipsita Banerjee received a $2.2 million, five-year award to study how embryonic stem cells develop into mature...

U.S. and Spanish scientists say they have proven, in principle, that a human genetic disease can be cured using a combination of gene and stem cell therapy. The researchers, led by the Salk Institute for Biological Studies, said their achievement has catapulted the field of regenerative medicine significantly forward. It's been 10 years since human stem cells were first cultured in a Petri dish, Professor Juan-Carlos Izpisua Belmonte of the Center of Regenerative Medicine in Barcelona, Spain,...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
