are the furthest from development, but even if Geron's particular approach doesn't work, some experts predict that treatments could be available using these cells as early as a decade from now.
Ascidian larval muscle cells therefore provide an experimental system with which to explore an intrinsic genetic program for autonomous specification of embryonic cells
Every embryonic cell
will have exactly one potential enhancer-reporter.
After scientists first grew human embryonic stem cells in the laboratory in 1998, many researchers waxed about an imminent era of cellular-replacement therapy, where the blank slate embryonic cells
would be transformed into an array of tissues useful for treating Parkinson's disease, heart failure, diabetes, and other conditions.
The new version also allows the donor of the embryonic cells
to be identified, since the immunological make-up of the cells may be important if they are transplanted into patients.
This is the first commercially available test to leverage bioinformatics to inform in vitro fertilization (IVF) transfer decisions by identifying potential abnormalities across all 24 chromosomes (aneuploidy) from a single embryonic cell
Implantation of neural embryonic cells
into the brains of patients with Parkinson's disease improved their ability to move, according to the results of a study published in the June issue of the Archives of Neurology.
The report from scientists at the University of Illinois at Chicago identifies two enzymes that alter the expression of certain genes needed for embryonic cells
to differentiate and become endothelial cells.
Coaxing specialized adult cells to regress back into a more malleable, embryonic-stem-cell-like state (a process called "induced pluripotency") would also allow scientists to realize the therapeutic benefits of embryonic cells
without the thorny ethical problems that plague cells derived from embryos.
When the researchers put the embryonic cells
into mice and reactivated the gene, the cells formed healthy intestines.
But we already know embryonic cells
cannot generate placental tissue.
Japanese scientists reported they have successfully coaxed monkey embryonic cells
into forming dopamine-producing cells, a brain chemical involved in movement that is depleted in Parkinson's disease.
