CURRENT STEM CELL NEWS

1. Diabetes Drug may hold the cure for neurodegenerative diseases- says study.

Scientists from University of Toronto have studied the effects of the common Diabetic Drug Metformin on mouse and human brain stem cells and concluded that Metformin stimulates the mechanism by which these brain stem cells generate new brain cells thus opening up new avenues for treating neurodegenerative diseases.Click to read more...

2. Specific differentiation stage of cells effective for clinical transplantation in Parkinson's disease identified.

A team led by Dr. Lorenza Studer from New York has been able to label dopaminergic neurons derived from embryonic stem cells at early, mid, and late stages of differentiation and the associated genes. Their study's result that neurons at mid stage of differentiation are best for transplantation could help improvising cell transplant strategies for Parkinson's disease. Click to read more...

3. Abnormal Bone Marrow stem cells lead to Myelodysplastic syndromes - Researchers find proof

Researchers from Yeshiva University have found proof that abnormalities in Bone Marrow stem cells are the main cause for development of myelodysplastic syndromes (MDS) which can progress to acute leukemia. These findings could help in developing therapies for preventing and treating MDS. Click to read more...

4. Two key epigenetic regulators of fate of bone marrow stem cells discovered

Dr. Wang and his team from UCLA School of Dentistry have identified two key epigenetic regulators which can induce bone marrow stem cells to form bone cells instead of fat cells. This could pave way for treatments for osteoporosis. Click to read more...

5. Stem Cell transplant could help reverse Type I diabetes

A recent animal study has demonstrated that Stem cell transplantation could restore insulin levels in Type-I diabetic mice and reverse diabetes in these animals thus giving hope for millions suffering from Diabetes. Click to read more...

6. Human trials on Stem Cells to cure HIV bound to start

A research Institute from Australia has announced that their successful research on treating HIV affected patients by injecting blood stem cells which are modified to mimic a gene mutation found in some individuals who are resistant to HIV, is going to enter the stage of Clinical trials shortly. Click to read more...

7. Advanced Imaging technique helps visualize trafficking of immune cells into heart

An advanced intravital two-photon imaging technique has helped scientists visualize the trafficking of immune cells into the heart in vivo. These immune cells are responsible for the inflammation that ensues once the blood flow of the heart, stopped by a heart attack, is restored.Click to read more...

8. Possible Mechanism by which tumour cells escape vasculature and establish metastases identified

A recent article published in the Journal Cancer Cell has reported how a particular chemokine released by metastatic colon cancer cells binds to a particular receptor in the endothelial cells of the vasculature thereby triggering increased permeability of the vessels through specific signalling pathways. This increase in permeability helps the tumour cells to escape the vessels into the new tissue locations to establish metastases.Click to read more...

9. Tracking of stem cells using Magnetic iron oxide nanoparticles is safe- Says study

A research study has established that labeling of stem cells with superparamagnetic iron oxide (SPIO) particles for tracking them in vivo, is safe as these particles did not interfere with cell function and also did not have any early or late clinical side effects on parameters like blood pressure, perfusion, coagulation etc. Click to read more...

10. Non-viable tissue from Burn Injuries could offer potential cell source for Tissue Engineering

A new study has shown that cells from the Burn Eschar, the non-viable tissue that remains after burn injury could actually be a potential source of mesenchymal stem cells which will be useful in tissue engineering. Click to read more..

Really???

1. We all believe that our hearts cannot regenerate once it is cut. However an animal study in 2011 showed that the neonatal heart in 1 day old mice had the ability to regenerate after it was surgically resected while this regenerative potential was lost by 7 days of age. This study suggests that mammalian hearts appear to have a transient regenerative capability.

2. Did you know that scientists have come closer to eradicating malaria? They postulate that by injecting certain modified genetic elements, known as homing endonuclease genes, or HEGs into the mosquitoes, we will be able to shut down the genetic pathways needed for malarial transmission. Another important aspect is that these HEGs could be transmitted from this mosquito to its successive generations also.

Quote Corner:

“The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity”

- Albert Einstein
