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.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.

Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

ZIOPHARM announces new preclinical data from two darinaparsin studies on solid tumors

ZIOPHARM Oncology, Inc., a drug development company employing small molecule and synthetic biology approaches to cancer therapy, announced today new preclinical data from two separate studies of darinaparsin, a novel organic arsenic, in various solid tumor models at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, taking place November 12-16 in San Francisco.

EPO-secreting engineered vessels could reverse anemia

Patients who rely on recombinant, protein-based drugs must often endure frequent injections, often several times a week, or intravenous therapy. Researchers at Children's Hospital Boston demonstrate the possibility that blood vessels, made from genetically engineered cells, could secrete the drug on demand directly into the bloodstream.

Stem cell therapy within 2 or 3 weeks does not improve heart function after attack

A research network led by a Mayo Clinic physician found that stem cells obtained from bone marrow delivered two to three weeks after a person has a heart attack did not improve heart function.

Stem cell injections within two weeks may not help in post heart attack recovery

University Hospitals Case Medical Center researchers could still be close to giving heart attack patients a second chance-just not as they originally thought.

Fact-checking Romney's debate performance

CNN examines comments made by GOP presidential hopeful Mitt Romney regarding the possible dollar savings that could result by repealing the health law, while the AP revisits his positions regarding the Massachusetts health law he signed while that state's governor. Also in the news, more on Rick Perry's Texas and where the candidates state on health research.

Viewpoints: Conservative legal path on health law; Romney's plans for Medicare and vets; States moving on reform

A federal appeals court in the District of Columbia endorsed the constitutionality of health care reform this week in an opinion as notable for its authorship as for its legal reasoning. The majority opinion in the 2-to-1 decision was written by Judge Laurence Silberman, a stalwart of conservative jurisprudence whose views are said to be enormously influential in conservative legal circles.

Cultured ES cells can self-organize into three-dimensional tissue-like structures

The possibility that functional, three-dimensional tissues and organs may be derived from pluripotent cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), represents one of the grand challenges of stem cell research, but is also one of the fundamental goals of the emerging field of regenerative medicine.
