When most groups of mammalian cells are faced with a shortage of nutrients or oxygen, the phrase “every man for himself” is more apt than “all for one, one for all.” Unlike colonies of bacteria, which often cooperate to thrive as a group, mammalian cells have never been observed to help one another out. But a new study led by a researcher at the Stanford University School of Medicine has shown that certain human embryonic stem cells, in times of stress, produce molecules that not only benefit themselves, but also help nearby cells survive.
“Altruism has been reported among bacterial

Before going ahead and explaining the possibilities that are on the verge of development based on the regenerative capabilities of a stem cell, let us first understand what a stem cell is actually. Stem cells are the basic group of cells that have the extremely potent capability of regenerating themselves. The process through which they regenerate themselves is known as mitotic cell division and after the division, the previously unspecialized cells turn into specialized cells for specific organs through cellular differentiation.
These cells are not found in unicellular organisms, but are found in varying quantities within all multi

Former Vice President Al Gore Endorses Trans-Pacific Collaboration to Promote Use of Patient Cells for Drug Discovery and Development and Cell-Based Therapies iZumi Bio, Inc., and Kyoto University‘s Center for iPS Cell Research and Application (CiRA), today announced a collaboration to promote the basic research, development and application of induced pluripotent stem (iPS) cell technology – a form of cellular reprogramming which originated in Japan – with the goal of advancing drug discovery and enabling cell-based therapies.
“Stem cell research holds great promise for the creation of new therapies that could revolutionize the treatment of disorders such
