However, some experts say only embryonic stem cells can generate the vast number of cells needed to cure some diseases.
Mr. LINKOV: We're not going to see fuel cells for a number of years.
Mice given the modified cells produced more than six times the number of "killer T" cells, which are immune cells produced to neutralise a target.
In other words, the adult cells had simply fused with the embryonic ones - the new cells had twice the number of chromosomes ("packets" of genetic material).
He estimates that his method could be available clinically in five years, after researchers find ways to reduce the required number of cells by a factor of 10 or even 100.
When there are a sufficient number of cells, scientists "seed" them -- much like you would seed a new lawn -- onto a mesh scaffold that is shaped like a urethra.
Two specific types of immune system cell that attack invaders - CD4 T-cells and natural killer cells - increased in number with age, with a higher rate of increase in women than in men.
The Scripps Research Institute team had already boosted the number of cells created with two compounds initiating a naturally occurring process that moves the cell nearer to a stem-cell like state.
The extreme microscope will enable a number of subjective and time-consuming tasks such as counting the number of cells staining positive for a biomarker or locating cells infected with a parasite like malaria, to be replaced by highly repeatable and robust computer vision applications.
An electron microscope would be unreliable, particularly for someone infected a long time, because the number of cells harboring virus genes would be diluted over time and difficult to detect, said McGowan, the New York and New Jersey chairman of the American Academy of HIV Medicine.
This happens during the production of sex cells, and its effect is to halve the number of chromosomes in a cell (the number returns to normal when two sex cells combine during fertilisation).
The number of these vessels correlated strongly with the number of metastatic cells in the lymph nodes and lungs.
And though I later learned that the formula for projecting the number of jail cells was more nuanced, it was not inaccurate.
FORBES: A $5 Children's Book vs. a $47,000 Jail Cell -- Choose One
Dr. David Amaral of the MIND Institute says the team used automated techniques to estimate the number of brain cells in each amygdala.
But they have now discovered that by adding thiazovivin, a small molecule involved in cell survival, they doubled that to get 200 times the number of transformed cells.
So while the additional dissolved iron triggered an earlier-than-usual phytoplankton bloom, as the metal triggered growth in a greater number of phytoplankton cells, the bloom was only 15-20% larger than normal because the growth was limited by the amount of available nitrogen, another vital ingredient required for the organisms to develop.
The research has been promising so far, and has increased the number of functional liver cells the team has been able to maintain in artificial tissues.
ENGADGET: Researchers use 3D printer, sugar, to create a fake artery network for lab-grown tissue
Egli is among the handful of scientists who have been working to perfect the technique with human cells and in 2011, succeeded in producing human stem cells, but with double the number of chromosomes.
Benlysta is delivered directly into a vein (intravenous infusion) and is the first inhibitor designed to target B-lymphocyte stimulator (BLyS) protein, which may reduce the number of abnormal B cells thought to be a problem in lupus.
FORBES: Human Genome Sciences' Benlysta Approved To Treat Lupus
Geron had injected stem cells into the spine of a small number of spinal patients to test safety.
These T-cells were converted into stem cells, which could dramatically increase in number when grown in the laboratory.
Professor Barry said data suggested that the number of cases where stem cells were retrieved from the cord cell bank was still quite small.

The reason for this is believed to be to stop cancer in its tracks by preventing tumour cells from dividing more than a certain number of times. (Successful cancers often have a special enzyme that repairs telomeres.) The cost is that, eventually, even healthy tissue cannot renew itself.
Given intravenously, Kadcyla courses through the body, looking for breast-cancer cells with a distinguishing feature: a high number of a particular protein, called HER2, on their surface.
E5, and it combines a microprocessor with 3, 200 reconfigurable logic cells, a chunk of memory, and a number of other components.
The good news: There are a growing number of very competent companies manufacturing solar cells for efficient conversion of this sunlight to electricity.
Principia and a number of other teams also use the gallium cells.
If these can be identified, they hope that the number of these on the surface of tumour cells can be boosted, so they present an obvious target for "killer" cells in the body's immune system.
Professor Harry Moore, of the Centre for Stem Cell Biology at the University of Sheffield, UK, said there were a number of key differences between mice and human testes cells.
Figures for the number of inmates with access to Sky TV in their cells rose from 1, 536 in 2006 to 4, 070 in 2009.
