Stem Cells News and Research

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.

Unrepaired DNA Damage Can Persist for Years and Lead to Cancer Mutations

While most known types of DNA damage are fixed by our cells’ in-house repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer.

ALS Stem Cell Model Reveals Increased Susceptibility to Cell Death

Amyotrophic lateral sclerosis (ALS) is a fast-progressing neurodegenerative disease with an average survival time of three years. In ALS, certain types of neurons called motor neurons that are required for muscle contractions die off, leading to progressive paralysis affecting most muscles of the body. The molecular causes of ALS are poorly understood, and effective treatments are missing.
