New system developed for culturing stem cells

A researcher at the University of Wisconsin-Madison has developed a new method for culturing both embryonic and induced Pluripotent Stem Cells. The benefits of this appear to be that it doesn't use mouse proteins, currently part of the many existing approaches,  that could contaminate the stem cells.

From my understanding, this is another great step forward in developing the processes required for the wide spread therapeutic use of stem cells. Here's a link to the U.W. news site.

How To Make Your Own Stem Cells

This a great article explaining Somatic Cell Nuclear Transfer and how this technique can be applied to make matching stem cells for possible therapeutic use. This is an older and more controversial approach than using induced Pluripoten Stem Cells, but might avoid some of the current issues related to how iPSCs are created that increases the potential for malignancies and other issues.

SCNT related treatments are commonly referred to a therapeutic cloning. I believe this approach could be beneficial for creating both the types and volume of stem cells necessary to treat Cerebral Palsy. Another benefits of SCNT is that is should avoid graft vs. host issues, because the cells are identical to those of the patient.

Scripps research scientists find nerve cell activity drains stem cell pool in developing brain

Scripps Research recently published these findings in the journal Neuron. Through this study researchers discovered that stem cell replication decreases as brain activity increases. They also found that the protein Musashi1 possibly plays a role in regulating stem cell replication. As Musashi1 levels decrease, so does stem stell replication.

Does these finding mean that Musashi1 proteins could be used to stimlate repair in the adult brain? Or do these findings also suggest that stem cells used thearpeutically will self regulate as they begin to differentiate and brain activity increases? At a minimum this study suggests there are additional avenues to pursue for treatment of numerous neural diseases and conditions.

Cerebral Palsy Awareness Day

This video includes some great statistics about Cerebral Palsy. With advances in stem cell research, now is the time to make additional investments into Cerebral Palsy treatments. If anyone knows of any existing legislative or other efforts to increase funding for CP research please let me know. I am willing to participate in and to advocate for these initiatives!

Virus-free technique enables Stanford scientists to easily make stem cells pluripotent

This Feb. 2010 news release highlights a new method for inducing pluripotent stem cells that reduces some of the risks associated with using these cells for therapy. The initial induced cells are not neural, but hopefully this process can be used to create these types of cells as well and is another step towards safe stem cell therapies for all types of medical conditions, including Cerebral Palsy.
