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 identify stem-cell genes that help form plant organs

Plant stem-cells are master cells located at the tip of the stem and are part of a structure called the shoot apical meristem (SAM).

Researchers generate functional neurons from induced pluripotent stem (iPS) cells

In a new study, researchers were able to generate functionally mature motor neurons from induced pluripotent stem (iPS) cells, which are engineered from adult somatic cells and can differentiate into most other cell types.

Human stem cells provide a new model for Lou Gehrig's disease

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a devastating condition in which motor neuron degeneration causes progressive loss of movement and muscle tone, leading to death.

Discovery of gene that controls the production of tooth enamel

Researchers have identified the gene that ultimately controls the production of tooth enamel, a significant advance that could some day lead to the repair of damaged enamel, a new concept in cavity prevention, and restoration or even the production of replacement teeth.

Statins can stimulate cardiac muscle cell regeneration, improve heart function

Statins, used widely to treat elevated cholesterol, have been shown to prevent progression of coronary narrowing and to have other beneficial effects on the heart, such as reducing inflammation, that are independent of cholesterol.

Neuralstem's ALS trial on hold

Neuralstem, Inc. has announced its spinal cord stem cell trial to treat Amyotrophic Lateral Sclerosis (ALS) is on clinical hold and that the Federal Drug Administration (FDA) has provided the Company with specific comments, questions and recommendations for modifications to its protocol.

Mutations in two genes linked to most common brain cancers

Scientists at the Johns Hopkins Kimmel Cancer Center and Duke University Medical Center have linked mutations in two genes, IDH1 and IDH2, to nearly three-quarters of several of the most common types of brain cancers known as gliomas.

A stem cell bandage for your knee

Building on his previous work, Hollander and his team, which included Dr Wael Kafienah and Dr John Tarlton, announced in 2005 they had, for the first time ever, successfully grown human cartilage from a patient's own bone marrow stem cells.

Molecules self-assemble to provide new therapeutic treatments

Researchers in the laboratory of Samuel I. Stupp at Northwestern University have an interesting approach for tackling some major health problems: gather raw materials and then let them self-assemble into structures that can address a multitude of medical needs.

New device decreases wait times for patients needing immunotherapy

Researchers from the Children's Cancer Hospital at The University of Texas M. D. Anderson Cancer Center have created a device that significantly decreases the time needed to produce genetically manipulated T cells in preclinical tests for leukemia.

New understanding of how leukemia develops

In a collaborative study published Feb. 9, 2009, in the Proceedings of the National Academy of Sciences (PNAS), scientists performed a genome-wide expression analysis comparing highly enriched normal blood stem cells and leukemic stem cells, and identified several new pathways that have a key role in cancer development.
