New Way to Regrow Human Corneas Could Help Overcome a Major Cause of Blindness

July 16, 2014

1 Comment

Harvard-affiliated researchers have discovered a new way to regrow human corneas that could help researchers overcome a major cause of blindness. Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule that acts as a marker for hard-to-find limbal stem cells. This work, a collaboration among the […]

Scientists Coax Human Embryonic Stem Cells to Organize

July 1, 2014

0 Comments

Using geometry, scientists from the Laboratory of Stem Cell Biology and Molecular Embryology at Rockefeller University have coaxed human embryonic stem cells to organize themselves. About seven days after conception, something remarkable occurs in the clump of cells that will eventually become a new human being. They start to specialize. They take on characteristics that […]

Researchers Identify Major Obstacle to Converting Cells Back to Their Youthful State

January 31, 2014

2 Comments

Researchers from Yale University have identified a major obstacle to converting cells back to their youthful state — the speed of the cell cycle, or the time required for a cell to divide. A fundamental axiom of biology used to be that cell fate is a one-way street — once a cell commits to becoming […]

Scientists Grow Human Brain Tissue in a 3D Culture System

August 29, 2013

1 Comment

By using a new method, which modified an established approach to generate so-called neuroectoderm, scientists were able to grow human brain tissue in a three-dimensional culture system. Complex human brain tissue has been successfully developed in a three-dimensional culture system established in an Austrian laboratory. The method described in the current issue of Nature allows […]

A newly published study from scientists at the Gladstone Institutes details how researchers transformed the class of cells that form human scar tissue into those closely resembling beating heart cells. In the aftermath of a heart attack, muscle cells within the region most affected shut down. They stop beating. They die. And they become entombed […]

Researchers Sequence Genome of Human’s Closest Invertebrate Relative

August 20, 2013

0 Comments

Stanford researchers have sequenced the genome of mankind’s closest invertebrate relative, Botryllus schlosseri – a small sea creature that can regenerate its entire body from its blood vessels alone. At first glance, Botryllus schlosseri has very little in common with humans. The small sea creature fuses together with others to form colonies that look like […]

Cardiac Stem Cells Offer New Ways to Prevent and Treat Heart Failure

August 19, 2013

1 Comment

A newly published study shows for the first time that if cardiac stem cells are eliminated, the heart is unable to repair itself after damage. Researchers at King’s College London have for the first time highlighted the natural regenerative capacity of a group of stem cells that reside in the heart. This new study shows […]
