Scientists regenerate bone tissue using only proteins secreted by stem cells

May 13, 2015 by · Leave a Comment 

Scientists have discovered a way to regrow bone tissue using the protein signals produced by stem cells. This technology could help treat victims who have experienced major trauma to a limb, like soldiers wounded in combat or casualties of a natural disaster. The new method improves on older therapies by providing a sustainable source for fresh tissue and reducing the risk of tumor formation that can arise with stem cell transplants.

Stem cells age-discriminate organelles to maintain stemness

April 3, 2015 by · Leave a Comment 

Tissue stem cells, that continuously renew our tissues, can divide asymmetrically to produce two types of daughter cells. One will be the new stem cell, where as the other will give rise to the differentiating cells of the tissue.

Direct generation of neural stem cells could enable transplantation therapy

November 7, 2014 by · Leave a Comment 

Induced neural stem cells (iNSCs) created from adult cells hold promise for therapeutic transplantation, but their potential in this capacity has been limited by failed efforts to maintain such cells in the desirable multi-potent NSC state without continuous expression of the transcription factors used initially to reprogram them.

New technique allows scientists to find rare stem cells within bone marrow

October 7, 2014 by · Leave a Comment 

Deep within the bone marrow resides a type of cells known as mesenchymal stem cells (MSCs). These immature cells can differentiate into cells that produce bone, cartilage, fat, or muscle — a trait that scientists have tried to exploit for tissue repair.

Turmeric compound boosts regeneration of brain stem cells

September 26, 2014 by · Leave a Comment 

A bioactive compound found in turmeric promotes stem cell proliferation and differentiation in the brain, reveals new research published today in the open access journal Stem Cell Research & Therapy. The findings suggest aromatic turmerone could be a future drug candidate for treating neurological disorders, such as stroke and Alzheimer’s disease.

A non-toxic strategy to treat leukemia

September 12, 2014 by · Leave a Comment 

A study comparing how blood stem cells and leukemia cells consume nutrients found that cancer cells are far less tolerant to shifts in their energy supply than their normal counterparts. The results suggest that there could be ways to target leukemia metabolism so that cancer cells die but other cell types are undisturbed.

New reprogramming factor cocktail produces therapy-grade induced pluripotent stem cells

September 6, 2014 by · Leave a Comment 

Induced pluripotent stem cells (iPSCs)—adult cells reprogrammed back to an embryonic stem cell-like state—may hold the potential to cure damaged nerves, regrow limbs and organs, and perfectly model a patient’s particular disease. Yet through the reprogramming process, these cells can acquire serious genetic and epigenetic abnormalities that lower the cells’ quality and limit their therapeutic usefulness.

Stowers researchers reveal molecular competition drives adult stem cells to specialize

August 6, 2014 by · Leave a Comment 

Adult organisms ranging from fruit flies to humans harbor adult stem cells, some of which renew themselves through cell division while others differentiate into the specialized cells needed to replace worn-out or damaged organs and tissues.

Embryonic stem cells offer new treatment for multiple sclerosis

June 20, 2014 by · Leave a Comment 

Scientists in the University of Connecticut’s Technology Incubation Program have identified a novel approach to treating multiple sclerosis (MS) using human embryonic stem cells, offering a promising new therapy for more than 2.3 million people suffering from the debilitating disease.
