    Beginner's Luck: The Power of Stem Cells

    Young stem cells, like young people, have unlimited options before them. They can become anything – businessperson, farmer, heart cell, skin cell. But then instructions kick in, and the young stem cell helps create the part of the body it is fated to become. However, scientists may be able to use the early potential of stem cells to treat a number of diseases.

    The Helen and Martin Kimmel Institute for Stem Cell Research

    On the occasion of establishing the Helen and Martin Kimmel Institute for Stem Cell Research, the couple – decades-long friends of the Weizmann Institute – talks about why they chose to invest in stem cell research, and why they chose to do so at Weizmann. They also share their first meeting, which was at a Weizmann event, and their love of science.

    Israelis Make Major Breakthrough in Turning Mature Cells into Skin Cells

    Tel Aviv University and Weizmann Institute of Science researchers have shown it is possible to turn mature cells from the heart, brain and other organs in mice models into skin cells. Their findings, just published in the prestigious journal Nature Communications, proves for the first time that it is possible to repurpose the function of different mature cells across the body and harvest new tissue and organs from these cells. “The applications of this are unlimited – from transplants, which would eliminate long waiting lists and eliminate the common problem of immune system rejection of ‘foreign’ organs; to maybe one day curing deafness: taking any cell in the body and transforming it into melanocytes to aid in the restoration of hearing. The possibilities are really beyond the scope of the imagination,” said Prof. Carmit Levy of the TAU Sackler School of Medicine’s human molecular genetics and biochemistry department.

    “Brain on a Chip” Reveals How the Brain Folds

    Being born with a “tabula rasa” – a clean slate – is, in the case of the brain, something of a curse. Our brains are already wrinkled like walnuts by the time we are born. Babies born without these wrinkles – called smooth brain syndrome – suffer from severe developmental deficiencies and their life expectancy is markedly reduced. The gene that causes this syndrome recently helped Weizmann Institute of Science researchers to probe the physical forces that cause the brain’s wrinkles to form. In their findings, reported in Nature Physics, the researchers describe a method they developed for growing tiny “brains on chips” from human cells that enabled them to track the physical and biological mechanisms underlying the wrinkling process.
