Reprogrammed Cells Kept Bug-Free by SIRT1

(Genetic Engineering & Biotechnology News) – Regenerative medicine—the promise of rejuvenating or replacing damaged or diseased tissues—will most likely rely on the use of induced pluripotent stem (iPS) cells, which are obtained when adult cells are essentially thrown into evolutionary reverse. This abrupt change can be hard on cells, which may suffer chromosomal abnormalities and […]

Stem Cells Show Bizarre Absorption Property ‘Not Seen before in Cells’

(Medical News Today) – Scientists at the University of Cambridge in the UK have discovered that the nuclei of stem cells have the unusual ability to become thicker when stretched and thinner when compressed. The counterintuitive property – termed auxeticity – is already known to materials scientists, who see its application ranging from super-absorbent sponges […]

Researchers Unravel Complex Genetic Coding that Allows Embryonic Cells to Proliferate, Perform Myriad Biological Tasks

(News-Medical) – A team of interdisciplinary researchers took lung cells from the embryos of mice, choosing samples at different points in the development cycle. Using the new technique of single-cell genomic analysis, they recorded what genes were active in each cell at each point. Though they studied lung cells, their technique is applicable to any […]

New Initiative Could Ban Funding of Embryonic Stem Cell Research in Europe

(Forbes) – Encouraged by a recent European Union court decision banning the patenting of technologies that use human embryonic stem cells, a group of pro-life organizations has launched an initiative which, if it passes, will cut funding of embryonic stem cell research in the E.U.

Cloning Advance Using Stem Cells from Human Adult Reopens Ethical Questions

(Washington Post) – Scientists have grown stem cells from adults using cloning techniques for the first time — bringing them closer to developing patient-specific lines of cells that can be used to treat a whole host of ailments, from heart disease to blindness. The research, described in Thursday’s online edition of the journal Cell Stem […]

Researchers Discover New Marker Derived from Human Umbilical Cord Blood

(News-Medical) – The development of stem cell therapies to cure a variety of diseases depends on the  ability to characterize stem cell populations based on cell surface markers. Researchers from the Finnish Red Cross have discovered a new marker that is highly expressed in a type of stem cells derived from human umbilical cord blood, […]

Scientists Make First Embryo Clone from Adults

(The Wall Street Journal) – Scientists for the first time have cloned cells from two adults to create early-stage embryos, and then derived tissue from those embryos that perfectly matched the DNA of the donors. The experiment represents another advance in the quest to make tissue in the laboratory that could treat a range of […]
