Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Scientists may have figured out how to use stem cells to regenerate lost or injured tissue

In experiments with fruit flies, Johns Hopkins scientists have restored the insect's sperm-making stem cells by triggering cells on the way to becoming sperm to reverse course. The unexpected findings are described in the May 13 issue of Science.

Centre for Life opens with the UK’s first two human embryonic stem cell lines

The UK’s first two human embryonic stem cell lines, developed separately by researchers at King’s College London and the Centre for Life in Newcastle, are to be deposited in the UK Stem Cell Bank. The deposit coincides with the official opening of the Bank by Health Minister, Lord Warner, today (Wednesday 19 May 2004).

Inactivating a protective molecule may help chemotherapy for leukemia but harm bone marrow

Inactivating a protective molecule in leukemic cells to make them more vulnerable to chemotherapy might also make healthy blood-forming cells more sensitive to the toxic effects of those same drugs.

Study of hematopoietic stem cell transplantation for severe, treatment-resistant lupus

The study will include a basic research component to examine the roles of B and T cells, white blood cells in the immune system, in triggering lupus symptoms.

Embryonic stem cells may hold the key to regenerating damaged heart muscle

Embryonic stem cells may hold the key to regenerating damaged heart muscle, when transplanted within a 3-dimensional scaffold into the infracted heart, according to a new study coming out in June in the Journal of Heart and Lung Transplantation.

New research center created by leading blood and marrow transplant organizations

In their mission to improve transplant access and outcomes for patients, the National Marrow Donor Program® (NMDP) and the Medical College of Wisconsin’s International Bone Marrow Transplant Registry and Autologous Blood and Marrow Transplant Registry (IBMTR/ABMTR) have created the Center for International Blood and Marrow Transplant Research (CIBMTR.)

Bone marrow and stem cell transplantation rejection averted by UV light exposure

One of the unfortunate side effects of bone marrow and stem cell transplantation is that the newly implanted cells often stage an internal attack against the patient they're intended to help.

World's first gene therapy trial aimed at preventing cancer

The concept seems straightforward. If, at its heart, cancer is a disease of genes, then giving patients new genes should disarm cancer. Such treatment would replace missing or faulty genes that keep cell growth in check, or would flush the body with "super genes" that could attack and destroy cancer.

New studies put spotlight on replicative capacity of beta cells

Researchers at Harvard University and the Howard Hughes Medical Institute (HHMI) have discovered that insulin-producing beta cells in the pancreas that are attacked in type 1 diabetes are replenished through duplication of existing cells rather than through differentiation of adult stem cells.

Embryo testing could produce babies who might aid sick siblings

Parents with a child requiring stem cell transplantation can have genetic testing done on embryos prior to implantation to determine if the tissue type matches and the ensuing offspring could potentially serve as a donor to the affected child, according to a study in the May 5 issue of The Journal of the American Medical Association (JAMA).

Tooth cells may help treat Parkinson's disease

Cells derived from the inside of a tooth might someday prove an effective way to treat the brains of people suffering from Parkinson's disease.

New hope for advances in treatment methods for AIDS, Alzheimer's and age-related blindness

Pharmaceutical science leaders from the FDA, research institutions and top pharmaceutical companies will gather at the 2004 AAPS National Biotechnology Conference, AAPS' spring annual meeting.

New technique to deliver gene therapy to soft-tissue tumors

Using new research and technology that shows bone marrow-derived mesenchymal stem cells (MSCs) will engraft at the site of a tumor and contribute to the growth of stromal fibroblasts (the healthy tissue surrounding a tumor)

Transplanted bone-marrow cells could regenerate nerve cells in the brain

Findings of a preliminary study in this week's issue of THE LANCET suggest that transplanted adult bone-marrow cells could regenerate nerve cells in the brains of human stem-cell recipients. These early findings, if confirmed in future research, have implications for the treatment of neurodegenerative disorders such as Parkinson's disease.

Scientists get new motor neurons to migrate through the spinal cord

In experiments with rodents, Johns Hopkins scientists have used properly directed stem cells to successfully overcome what is thought to be a basic hurdle in restoring function to severely damaged central nervous systems

Injections of adult stem cells could repair hearts

Injections of adult stem cells into damaged heart tissue significantly improved heart function in patients with severe congestive heart failure, according to results of the first prospective randomized trial of the experimental therapy presented today at the American Association for Thoracic Surgery.
