Caution on stem cell therapy

Researchers discover at least one or two additional types of adult stem cells beyond Bmi1-expressing cells, found primarily in the upper third of the intestine. This finding complicates stem cell therapy for diseases such as Parkinson's and heart disease, requiring recognition of organ-specific stem cell complexity.

Scientific information largely ignored when forming opinions about stem cell research

Public attitudes toward embryonic stem cell research are influenced more by religious values and deference to scientific authority than scientific knowledge. For highly religious audiences, understanding the science has no effect on their views, while for less religious individuals, it is linked to more positive attitudes.

Medical College of Wisconsin researchers identify proteins that help develop mammalian hearts

The study identifies GATA4 and GATA6 as crucial proteins controlling heart cell formation. Without these proteins, embryonic stem cells fail to develop normal hearts. The findings have significant implications for the production of heart cells from stem cells and may help unravel the mechanisms behind congenital heart disease.

Stem cells and cancer: cancer pathways that also control the adult stem cell population

Researchers have found that a key gene called Apc plays a crucial role in controlling adult stem cells and preventing tumours. The study suggests that when this gene is lost or damaged, the normal function of adult stem cells breaks down, leading to cancer. This research has important implications for using adult stem cells for therapy.

UCLA researchers find blood stem cells originate and are nurtured in the placenta

Researchers have made a groundbreaking discovery about the origin of blood stem cells, finding that they are generated in the placenta. The study's findings may allow for the growth of blood stem cells in cell culture, potentially leading to new treatments for diseases like leukemia and aplastic anemia. By understanding how blood stem ...

UCLA stem cell scientists reprogram human skin cells into embryonic stem cells

UCLA stem cell scientists have successfully reprogrammed human skin cells into embryonic stem cells without using embryos or eggs. This breakthrough uses genetic alteration to turn back the clock on human skin cells and create cells nearly identical to human embryonic stem cells, which can become every cell type in the human body.

USC researchers identify mechanism that controls activation of stem cells during hair regeneration

Researchers at USC have identified a novel signaling mechanism that coordinates stem cell activity and regulates hair regeneration in large populations of hairs in animal models. The study found that periodic expression of bone morphogenetic protein (Bmp) in the skin macro-environment is key to coordinated hair stem cell activation.
