Stem cells progress against ALS

Studies begun by Harvard Stem Cell Institute (HSCI) scientists eight years ago have led to a report published today that may be amount to a major step in developing treatments for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease.

The findings by Kevin Eggan, a professor in Harvard’s Department of Stem Cell and Regenerative Biology (HSCRB), and colleagues also has produced functionally identical results in human motor neurons in a laboratory dish and in a mouse model of the disease, demonstrating that modeling the human disease with customized stem cells in the laboratory could relatively soon eliminate some

Stem cells overcome major cause of blindness

Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule that acts as a marker for hard-to-find limbal stem cells.

This work, a collaboration among the Harvard-affiliated Massachusetts Eye and Ear/Schepens Eye Research Institute, Boston Children’s Hospital, Brigham and Women’s Hospital, and the VA Boston Healthcare System, holds promise for burn patients, victims of chemical injury, and others with damaging eye diseases.

The research, published this week in the journal Nature,is also one of the first examples of constructing a tissue from an adult-derived human stem cell.

Limbal stem cells reside in the eye’s

New hope for SCID disease

Children born with so-called “bubble boy” disease have the best chance of survival if they undergo a hematopoietic stem cell transplant as soon after birth as possible, according to a detailed analysis of 10 years of outcome data by researchers at the Harvard-affiliated Dana-Farber/Boston Children’s Cancer and Blood Disorders Center.

Researchers say the findings support expanding newborn screening for severe combined immune deficiency (SCID), a disorder that leaves affected infants so vulnerable to infection that most die within the first year of life if untreated.

The study, published today in the New England Journal of Medicine, analyzed data on 240 children

Enhancing the regenerative capacity of stem cells

tem cell scientists scored what at first appeared an easy win for regenerative medicine when they discovered mesenchymal stem cells several decades ago. These cells, found in bone marrow, can give rise to fat, bone, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair. Unfortunately, the results of these trials have been underwhelming. One problem is that these stem cells don’t stick around in the body long enough to benefit patients.

But Harvard Stem Cell Institute (HSCI) scientists at Boston Children’s Hospital aren’t ready to give up. A research team led by Juan Melero-Martin

Stem Cell Therapy is Reality

The mesenchymal stem cells found in the bone marrow can give rise to bone, fat, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair.

Unfortunately, the results of these trials have been underwhelming, the main problem being that these stem cells do not stick around in the body long enough to benefit the patient.

Researchers have now found that transplanting mesenchymal stem cells along with blood vessel-forming cells naturally found in circulation improves results.
