New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells.   view more (2009-11-24)

Umbilical cord blood stem cell transplant may help lung, heart disorders
Two separate studies published in the current issue of Cell Transplantation (18:8), - now freely available on-line have shown that transplanted human-derived umbilical cord blood (UCB) stem cells transplanted in an animal model had positive therapeutic effects on specific lung and heart disorders the animal models.   view more (2009-11-24)

Measuring and modeling blood flow in malaria
When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells.   view more (2009-11-23)

Johns Hopkins researchers track down protein responsible for chronic rhinosinusitis with polyps
A protein known to stimulate blood vessel growth has now been found to be responsible for the cell overgrowth in the development of polyps that characterize one of the most severe forms of sinusitis, a study by Johns Hopkins researchers suggests.   view more (2009-11-23)

Is hepatic differentiation of embryonic stem cells induced by valproic acid and cytokines?
Embryonic stem (ES) cells, known for their capacity to proliferate indefinitely and differentiate into almost all types of cells including hepatocytes, have raised the hope of cellular replacement therapy for liver failure.   view more (2009-11-18)

Cornell researchers identify a weak link in cancer cell armor
The seeming invincibility of cancerous tumors may be crumbling, thanks to a promising new gene therapy that eliminates the ability of certain cells to repair themselves.   view more (2009-11-13)

Exploration by explosion: Studying the inner realm of living cells

New findings on the formation of body pigment
The skin's pigment cells can be formed from completely different cells than has hitherto been thought, a new study from the Swedish medical university Karolinska Institutet shows. The results, which are published in the journal Cell, also mean the discovery of a new kind of stem cell.   view more (2009-10-19)

Shedding light on cancer cells
Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells.   view more (2009-09-25)

The vasculature emerges as a potential therapeutic target in treating ADPKD liver cysts
As part of an effort to develop effective medical therapies that block the progression of liver cyst growth in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD), researchers at the University of Colorado Anschutz Medical Center have found that the liver cyst walls develop and maintain a vasculature as they grow out from the body... view more...
