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.

New target found for asthma

An enzyme released by mast cells in the lungs appears to play a key role in the tightening of airways that is a hallmark of asthma -- pointing to a potential new target for treatment against the illness.

Adult stem cell application effective in treatment of peripheric vascular disease

Multipotent adult progenitor stem cells extracted from bone marrow, and known as MAPCs, have proved to be effective in the regeneration of blood vessel tissue and also in muscle tissue when treating peripheric vascular disease.

Researcher transplants stem cells to try to save patients' legs

A Northwestern University Feinberg School of Medicine researcher has launched the first U.S. trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation in their legs.

German Research Foundation skeptical on cloning of human cells

According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory.

Stem cell research aims to tackle Parkinson's disease

Scientists in Sweden are developing new ways to grow brain cells in the laboratory that could one day be used to treat patients with Parkinson's disease, an international conference of biologists organised by the European Science Foundation (ESF) was told last week.

Scientists uncover role of cancer stem cell marker: controlling gene expression

Scientists at Jefferson's Kimmel Cancer Center in Philadelphia have made an extraordinary advance in the understanding of the function of a gene previously shown to be part of an 11-gene "signature" that can predict which tumors will be aggressive and likely to spread.

Cancer stem cell marker also drives transcription in normal cells

New research links the recently discovered function of a multi-faceted transcriptional complex to control of gene expression in both normal cells and cancer stem cells.

Molecules might identify high-risk acute-leukemia patients

New research suggests that certain small molecules used by cells to control the proteins they make might also help doctors identify adult acute-leukemia patients who are likely to respond poorly to therapy.

University of Minnesota researchers have created a beating heart in the laboratory

By using a process called whole organ decellularization, scientists from the University of Minnesota Center for Cardiovascular Repair grew functioning heart tissue by taking dead rat and pig hearts and reseeding them with a mixture of live cells. The research will be published online in the January 13 issue of Nature Medicine.

Stem cells make bone marrow cancer resistant to treatment

Scientists at the Johns Hopkins Kimmel Cancer Center say they have evidence that cancer stem cells for multiple myeloma share many properties with normal stem cells and have multiple ways of resisting chemotherapy and other treatments.
