In the most recent issue of Cell Stem Cell, a new study out of the laboratory of Dr. Lee Rubin at the Harvard Stem Cell Institute, reports the identification of a new small molecule that might be effective in treating Amyotrophic Lateral Sclerosis (ALS). Otherwise known as Lou Gehrig’s

syndrome, ALS is a neurodegenerative disorder that results in motor neuron death, severe debilitation, and ultimately death. To date, there are few therapeutic options, with a median survival time from onset to death of around 39 months.
In this study, Yang et al. derived motor neurons from mouse embryonic stem cells and performed a drug screen in the culture dish to identify novel molecules that might preserve or inhibit the death of motor neurons. The group found many different hits, but one molecule that showed a robust and reproducible effect on motor neuron survival in many of their assays was kenpaullone. This molecule is a GSK3-beta inhibitor, and the authors go on to show that in addition to this, it also inhibits HGK kinase in motor neurons.
In addition to promoting the survival of mouse motor neurons, they also used human iPSC lines derived from ALS patients and showed a positive survival effect on human motor neurons. This new study demonstrated the power of pluripotent technology to search for novel drug candidates to use as therapeutics for debilitating diseases with no current cures.
Congratulations to Dr. Rubin and his group for this fantastic study, and good luck moving forward! For more information, please see the link below:

HOW MY WIFE GOT CURED FROM ALS, With the use of Stem Cell and other recipe
Below is how i got a cure for my wife who suffered from Amyotrophic Lateral Sclerosis ( ALS). .
I lost my dad to ALS 5 years ago , he suffered from the dreaded disease for 6 years with his doctor telling us he can’t be cured and all the therapies and life support machines could not save him and 3 years later my wife was also diagnosed of the same disease and i was devastated she fainted when the doctor read the diagnosis because she knew how deadly the disease was. In a year her condition worsened and she was unable to move and she was confined to the bed the direction the disease has taken with her body is the gradual deterioration of the “Bulgar muscle,” which controls breathing, swallowing, voice, and tongue movement. Her neck muscles have weakened to the point that she can’t hold her head up and the left side of her body is weaker than the right , the doctors told me all her muscles were dead, she was able to eat via a machine because she could not swallow anything. I searches and tried different neurologist and different medicines none worked and i was so scared to lose my wife. While running up and down seeking for a solution i met my friend from third grade saw me all worked up, we got talking and in the process of discussion i told him all i am facing. He felt sad and told me about Dr. Hassan who was able to cure his cousin. I was interested and he gave me his contact. I contacted him and he came down to where my wife was and started to treat her with his medicine and in a space 3 weeks she was up on her feet again and in 4 week she recovered fully. She can do normal things like walking, eating, without any assistance whatsoever. I am so amazed at the potency and effectiveness of his medicine.he also dose delivery too via DHL courier delivery service. I decided to share my story for you not to lose hope or feel your world has ended you too can be okay like my wife. Simply contact him on his mail, for more information about his treatment. I hope this helps someone out there.write Him on (drhassanherbscure@gmail.com)
whatsapp ( 2349032582239 ) I hope this helps someone out there . he told me he can also cure HSV 1& 2, Cancer ,Diabetics ,HIV/AIDS ,Heart failure.Kidney problem and so much more
