UCLA's Yi Sun, an associate professor of psychiatry and biobehavioral sciences, and Howard Hughes Medical Institute investigator Thomas Südhof at the University of Texas Southwestern Medical Center were able to produce 70 to 80 percent of neurons in cell culture. (sciencedaily.com)
We're excited because we have been able to purify so many more neurons out of the cell culture and they were, surprisingly, healthy enough to form synapses. (sciencedaily.com)
The cells were then put into a cell strainer that allowed passage through of the isolated neurons. (sciencedaily.com)
Using the same techniques to prod the two embryonic stem cells lines to differentiate, Sun found that one line had a bias to become neurons that are found in the forebrain. (sciencedaily.com)
If you're studying a disease found in a certain part of the brain, you should use a human embryonic stem cell line that produces the neurons from that region of the brain to get the most accurate results from your study. (sciencedaily.com)
Huntington's disease, for example, is a forebrain disease, so the neurons should be differentiated from a cell line that is biased to produce neurons from the forebrain. (sciencedaily.com)
Sun said there are ways to prod an embryonic stem cell line biased to become neurons found in the rear brain to become neurons found in the forebrain. (sciencedaily.com)
Led by Prof. Malin Parmar, the team differentiated dopaminergic neurons from human embryonic stem cells in culture, then transplanted them into the brains of rats that were modeled to exhibit the symptoms of Parkinson's. (medgadget.com)
Prof. Parmar and colleagues showed that following transplantation, the embryonic stem cell-derived dopaminergic neurons exhibited the functional characteristics of native dopaminergic neurons, including dopamine production as well as long distance extension and connection with target regions in the brain. (medgadget.com)
Unlike fetal stem cells, which have been previously used to create dopaminergic neurons, embryonic stem cells (from existing stem cell lines) offer an abundant, readily accessible supply of cells. (medgadget.com)

States, not the federal government, now fund the majority of human embryonic stem cell research conducted in the United States, according to a recent study in the journal Nature Biotechnology . (scienceblog.com)
In addition, states varied substantially in the extent to which they prioritized human embryonic stem cell research, and much of the research performed in the states could likely have been funded by the National Institutes of Health under federal guidelines established by President Bush in 2001. (scienceblog.com)
While the federal government still contributes more to stem cell research overall, each year since 2007 these six states have funded more human embryonic stem cell research than the federal government," said Aaron Levine, assistant professor at Georgia Tech. (scienceblog.com)
Levine created an online searchable database ( http://www.stemcellstates.net/ ) that allows users to find detailed information about each grant given out by the six states that adopted programs specifically to fund stem cell research. (scienceblog.com)
From what I could tell, only a relatively small portion of the stem cell research supported by these states was clearly ineligible for federal funding," said Levine, who is on the faculty of the School of Public Policy in the Ivan Allen College of Liberal Arts. (scienceblog.com)
He said he was surprised at how great the difference was among states in the share of grants that supported human embryonic stem cell research. (scienceblog.com)
The papers made fantastic claims about embryonic stem cell research studies that turned out to be false. (lifenews.com)

Rep. Dave Weldon (R-FL) on the House floor, regarding stem cell research: 'The truth is that embryonic stem cell research is perfectly legal in the U.S. Every lab in America could do embryonic stem cell research,' he said. (physiciansforlife.org)
The real value of over two decades of ES-cell research currently lies with these advances but there has been relatively little external acclaim or general interest. (scitizen.com)
These debates will, and must, rage on but it interesting that two things in particular seem to be lost to most debates on the issue: (i) the value of research to this point in time, and (ii) the likelihood that the use of stem cells of any type to treat most if not all these diseases remains, for a variety of reasons, a distant possibility.

Established by George Todaro and Howard Green in 1962 from disaggregated Swiss mouse ( Mus musculus ) embryo tissue, the 3T3 cell line is a standard fibroblast cell line used in a wide spectrum of research and industrial biomedical applications. (fsu.edu)
However, due to examination of 3T3 cells and subsequent research it has become widely accepted that for immortalization of cells to take place, telomere shortening, which can instigate chromosomal rearrangements, must be overcome, a process that is not necessarily related to a cell s ability to undergo oncogenic transformation. (fsu.edu)
The changes, which include new guidelines for company-sponsored academic research and lab-to-lab transfer of cells, have thus far been welcomed by the hESC research community. (consumerwatchdog.org)

The nucleus of an adult somatic cell (such as a skin cell) is removed and transferred to an enucleated egg, which is then stimulated with electric current or chemicals to activate cell division. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)

As stem cells within a developing human embryo differentiate within the cell, their capacity to diversify generally becomes more limited and their ability to generate many differentiated cell types also becomes more restricted. (erlc.com)
Adult stem cells are sometimes referred to as somatic stem cells to differentiate them from human germ cells, sperm cells and egg cells. (erlc.com)
