Success with bioengineered human livers

Cincinnati - Scientists working on the development of artificial human livers have shown some success by bioengineering human liver tissues. The livers were generated from healthy and usable human liver tissue from human pluripotent stem cells.

Graphene used to change stem cells for nerve regrowth

Scientists have successfully changed stem cells for nerve regrowth by harnessing the properties of the versatile material graphene together with electricity.

Heart tissue grown on spinach leaves

To overcome a problem of growing human organs in a laboratory, researchers have turned to plants to establish a vascular system that delivers blood deep into the developing tissue. Here beating human heart cells have been grown on spinach leaves.

Scientists engineer human stomach for research

Cincinnati - Scientists have successfully grown functional stomach and intestinal tissues. This has been created to study diseases and new drugs, and looking at the interactions between health and disease.

Patient’s own stem cells used to heal burns

In an important scientific breakthrough a company has devised a spray, based on stem cells, that helps skin to regenerate after it has been badly burned. This is a replacement to skin grafts.

Blow for bone marrow transplant as stem cells age

Bone marrow transplants are tricky procedures, particularly with blood-related problems. Now a new concern has been raised: rapid cellular ageing.

Scientists think it's possible to reverse the aging process

The fountain of youth may be a myth but a gene called Nanog might lead to the same effect. A new research breakthrough could bring with it treatments for conditions like atherosclerosis, osteoporosis and Alzheimer’s.

3D pen successfully prints stem cells

A further advancement with three-dimensional printing has been made in the biology field. This is with a pen-like device that could be used to make cartilage implants during live operations.

New stem cell therapy may regenerate lost limbs in a few years

A groundbreaking discovery from an Australian research team at the University of New South Wales (UNSW) may pave the road for the future of stem cell technology. Thanks to this new research humans may regrow their lost limbs in just a few years.

Fully functional human liver grown in lab

The search for artificial organs continues. In a recent step-forwards, scientists have produced the most realistic lab-grown liver tissue yet seen. This is through lab-on-chip technology.

Laboratory-made blood to begin trials

Cambridge - The U.K. National Health Service (NHS) aims to test blood made in a laboratory within the next two years. This could signal a move away from blood donations.

Compound from plants targets cancer stem cells

By using an enzyme and compound found in broccoli and Brussels sprouts, researchers have devised a chemical that can potentially prevent the re-occurrence of certain types of cancer. This is based on research in human cervical cancer stem cells.

New technology for making living tissue

A new method for constructing large tissues from living components of three-dimensional micro-tissues has been developed. Researchers hope that the process can one day building entire organs.

Scientists grow human intestines inside a mouse

Scientists have begun growing human intestines in mice. The object of the research is to pave the way for better models of intestinal function and failure.

Op-Ed: Should a genetics company plan to create new creatures?

San Francisco - A San Francisco-based biotech wants to see its technology applied for inventing new organisms. This has raised concerns about so-called “Frankenstein science.”

Lab grows proto egg and sperm cells

Using stem cells, scientists have generated early egg- and sperm-like cells within a laboratory. This could be a step towards a cure for infertility.

Op-Ed: Using human brain cells to smarten up the mouse

The Journal of Neuroscience reports that brain cells from one animal species can be transplanted into that of another species and thrive. With an extent and relative rapidity, implanted human brain cells can actually take over the brains of mice.

Stem cells directed towards embryo development

Cambridge - Embryonic stem cells can form any tissue. However, scientists have struggled to develop a properly organized embryo. This appears to have changed with some recent research.

Lab creates first human stomach tissue in a dish

Cincinnati - Researchers have created three-dimensional human stomach tissue in a laboratory by using stem cells. The living tissue can be used to develop treatments against diseases like cancer.

Can electromagnets 're-program' cells?

Scientists have reported that electromagnetic exposure facilitates cell reprogramming. Not all scientists are convinced.

Paralyzed man walks again

A remarkable story: a paralyzed Bulgarian man called Darek Fidyka is walking again after novel treatment by doctors. The treatment consisted of implanted regenerative cells.

Op-Ed: Has Alzheimer’s been recreated in a stem cell lab study?

According to a newly published report, scientists have used a novel three-dimensional culture method to recreate the plaques and tangles of the neurodegenerative disease Alzheimer’s.

Op-Ed: Do stem cells offer diabetes cure potential?

Scientists have developed hormone-producing pancreas cells from human embryonic stem cells. This could pave the way for a cell therapy to treat diabetes.

‘Alzheimer’s in a Dish’ a breakthrough in search for cure

Scientists have succeeded in replicating human brain cells with typical Alzheimer’s Disease structures. Up to now, researchers searching for a treatment have had to work with mouse brains, an imperfect and unsatisfactory substitute.

Researchers say stem cells could provide Type I diabetes cure

A team of Havard University researchers believe they have found a cure for Type I diabetes using stem cells to create the kind of insulin-producing cells that victims of Type I diabetes lack.

Op-Ed: Stem cell superheroes and the limits of our biology Special

Ever thought about having the powers or abilities of a superhero? We can improve our abilities by training and effort, but enhancing the human condition really has biological limits. What if we could exceed the constraints of our biology?

Stem cell study for eye disease

Kobe - Scientists at the RIKEN Center for Developmental Biology will shortly treat the first patient in using a stem cell-based treatment for age-related macular degeneration.

3D printers, food and the human body

Natick - 3D printing can technically create a pattern and then an object from nearly anything. Both food and human organs are items scientists are currently researching.

Can stem cells be used to treat autism?

Duke University is launching a $41 million stem-cell trial to explore the use of umbilical cord blood cells to treat autism, stroke, cerebral palsy, and related brain disorders.

Lawsuit claims stem cells unsafe

San Fransisco - StemCells, Inc., a California company developing cell therapies for a range of conditions, is being sued by a former employee who claims that the company did not follow proper protocol in preparing treatments.
