An international team of scientists led by researchers at the University of California, San Diego School of Medicine have used induced pluripotent stem cells (iPSCs) derived from patients with amyotrophic lateral sclerosis (ALS) to reveal for the first time how reduced levels of a specific protein may play a central role in causing at least one inherited form of the disease.

 In a study that increases the understanding of the link between fetal development and obesity later in life, researchers at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) found altering the levels of two common hormones, insulin and leptin, in utero changes the cellular development in the region of the brain that regulates appetite.

 Stem cell technologies have been proposed for cell-based diagnostics and regenerative medicine therapies. However, being able to make stem cells efficiently develop into a desired cell type -- such as muscle, skin, blood vessels, bone or neurons -- limits the clinical potential of these technologies.

 New research in mice suggests that adult stem cells from immune system tissue in the smell-sensing region of the human nose (human olfactory ecto--mesenchymal stem cells [OE-MSCs]) could provide a source of cells to treat brain disorders in which nerve cells are lost or irreparably damaged.

 A research breakthrough has proven that it is possible to reprogram mature cells from human skin directly into brain cells, without passing through the stem cell stage. The unexpectedly simple technique involves activating three genes in the skin cells; genes which are already known to be active in the formation of brain cells at the fetal stage.

The ultimate source of some cancers is embryonic cells. Research published in the June 24th Cell, a Cell Press publication, traces the precursor of deadly esophageal cancers to leftover embryonic cells found in all adults.

Blood stem cells, as from a bone marrow transplant, are used to treat serious cancers. Therapies using other types of stem cells, mostly still experimental, are envisioned to help repair damaged organs and to treat scourges like diabetes and Parkinson’s disease.

 Innovative adult stem cell research by scientists at The University of Texas Health Science Center at Houston (UTHealth) could aid efforts to apply the brakes to stem cells that produce the type of fat ringing the waists of millions. Research appeared online ahead of the print issue of Cell Stem Cell.

 Scientists have known for years that neurogenesis takes place throughout adulthood in the hippocampus of the mammalian brain. Now Columbia researchers have found that under stressful conditions, neural stem cells in the adult hippocampus can produce not only neurons, but also new stem cells.

 Whitehead Institute researchers have identified signals from breast epithelial cells that can induce those cells to transition to and maintain a mesenchymal and stem cell-like cell state that imbues both normal and cancer cells with a greater ability to migrate and self-renew.
