Adult Stem Cells–Saving Legs, Saving Lives

Excerpt:

Previous stories focused on the science of treating peripheral artery disease with adult stem cells. Often overlooked are the people whose lives have been changed or even saved by adult stem cell treatments.

Helen Thomas, 80, of Hastings, Michigan is one of those people. Helen’s painful circulatory problem in her leg meant she had trouble walking, rarely left home, and was facing amputation of her leg. But her physician, Kenneth Merriman of Hastings, asked around at a medical conference and found Dr. Randall Franz, who was doing a clinical trial at Grant Medical Center in Columbus, Ohio. Franz injected Helen’s own adult stem cells into her leg, causing new blood vessels to grow. Helen is now up and about, back to normal.

A Neurological Save with Adult Stem Cells

Excerpt:

When she was 30, Jennifer Osman was diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP), a neurological disorder that attacks the peripheral nervous system, progressively weakening and numbing its victim.

[…]Then Jennifer signed up for an adult stem cell study run by Dr. Richard Burt, chief of the Division of Immunotherapy at Northwestern University Feinberg School of Medicine. Her adult stem cells were collected and she received chemotherapy to knock out the rogue immune cells attacking her nervous system. Shortly after, on April 1, 2005, Jennifer received a transplant of her own adult stem cells and her immune system, now rebooted, began to rebuild itself. The process was slow and grueling, but she has taken no medication for the disease since 2008. Today, almost five years since her transplant, she is nearly symptom-free.

You Call That “Success”?

Excerpt:

A news story out yesterday exemplifies the “successes” of embryonic stem cells. The story proclaimed that scientists had “successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa.” Sounds pretty good? Later there is the requisite hyperbole about treatments, that “Once the complication issues are addressed” and a list of retinal diseases that will be treated with embryonic stem cells.

Seeing Real Success with Adult Stem Cells

Excerpt:

In a paper published February 15, 2010, Oregon scientists showed that they could use bone marrow-derived adult stem cells to treat a rat model of retinitis pigmentosa. Visual function was significantly preserved in this study. An added benefit was that the cells could be easily grown in culture and administered intravenously; once injected, they traveled to the retina where they exerted their protective effect. The study highlights the possibility of using a patient’s own adult stem cells for treatment of retinitis, diabetic retinopathy, and macular degeneration.

A study by Canadian and Japanese researchers used human retinal stem cells that had been modified to increase their differentiation potential. When injected into the eyes of mice, the adult stem cells survived and differentiated into photoreceptors. Injected into a mutant mouse strain that lacks functional photoreceptors, the adult stem cells significantly improved visual function. The study was published online in the journal Stem Cells December 11, 2009.

Something to think about when the topic of embryonic stem cells comes up.

Ethically-sound adult stem cell research cures paralysis in human patients

Leave a comment

There are two kinds of stem-cell research. The first kind is called embryonic stem-cell research (ESCR). This kind is opposed by pro-lifers because it kills unborn persons by extracting their stem cells for use in medical research. The second kind is called adult stem-cell research (ASCR). This kind is supported by pro-lifers.

You may be surprised to know that ESCR doesn’t work as nearly as well as ASCR. Despite all the advocacy from left-wing Hollywood actors, ESCR has not helped a single patient. But ASCR in being used for 73 different kinds of therapies, and it keeps getting better and better. Here’s the latest scientific discovery in ASCR.

Story from Wayne State University, which made the discovery. (H/T Secondhand Smoke via ECM)

Excerpt:

A new study by a Wayne State University School of Medicine researcher details the outcome of adult stem cell grafts in spinal cord injuries and how the procedure led to increased mobility and quality of life for patients.

Associate Professor Jean Peduzzi-Nelson of the Department of Anatomy and Cell Biology conducted the study, “Olfactory Mucosal Autografts and Rehabilitation for Chronic Traumatic Spinal Cord Injury,” which was published online in the journal Neurorehabilitation and Neural Repair.

The process involves the use of adult stem-like progenitor cells in the patient’s own nasal tissue. The use of a person’s own stem cells, Peduzzi-Nelson said, lessens the problems of rejection, tumor formation and disease transmission.

In the study, 20 patients with severe chronic spinal cord injuries received a treatment combination of partial scar removal, transplantation of nasal tissue containing stem cells to the site of the spinal cord injury and rehabilitation. All of the patients had total paralysis below the level of their spinal cord injury before the treatment.

Wesley J. Smith notes that ASCR is getting more and more efficient:

A team led by scientists from The Scripps Research Institute has developed a method that dramatically improves the efficiency of creating stem cells from human adult tissue, without the use of embryonic cells. The research makes great strides in addressing a major practical challenge in the development of stem-cell-based medicine…

The new technique, which uses three small drug-like chemicals, is 200 times more efficient and twice as fast as conventional methods for transforming adult human cells into stem cells (in this case called “induced pluripotent stem cells” or “iPS cells”). “Both in terms of speed and efficiency, we achieved major improvements over conventional conditions,” said Scripps Research Associate Professor Sheng Ding, Ph.D., who led the study. “This is the first example in human cells of how reprogramming speed can be accelerated. I believe that the field will quickly adopt this method, accelerating iPS cell research significantly.”

Democrats introduce bill to punish infanticide as a felony, not murder

Leave a comment

UPDATE: Sorry, the headline from before should read that infanticide up to one year will be reduced to a felony, not legalized outright! My mistake!

A post at Gateway Pundit, sent to me by the greatest commenter in the blogosphere, ECM.

Gateway Pundit has a link to the bill, but Cassy Fiano has a lot more.

Here’s a bit about the bill:

It defines infanticide as:

A person commits an offense if the person wilfully by an act or omission causes the death of a child to whom the person gave birth within the 12-month period preceding the child’s death
The bill says that infanticide should not be prosecuted as murder, though, as long as:

… at the time of the act or omission, the person’s judgment was impaired as a result of the effects of giving birth or the effects of lactation following the birth.
Infanticide would become a felony, punishable by no more than two years in prison, with a minimum of 180 days, and/or a fine of no more than $10,000.

We need to start getting serious about defending the pro-life view using facts and arguments. Here’s some stuff to get you started. Disagreeing with people is fun once you take time to learn your stuff in detail.

Here is a new video featuring pro-life supermodel Kathy Ireland talking to Mike Huckabee, who strikes as very ignorant. (No surprise, given his terribly uninformed positions on illegal immigration and fiscal policy!)

The Wintery Knight strongly approves of pro-life supermodels!
