    Stem Cells Might Heal Damaged Lungs

    The insight that bone marrow and lung stem cells are quite similar led Prof. Yair Reisner and his team to investigate whether transplant methods used for bone marrow might also work for treating lung diseases such cystic fibrosis and asthma. When mice with lung damage were given the new stem cell treatment, their lungs healed and breathing improved.

    Human Primordial Cells Created in the Lab

    Weizmann's Dr. Jacob Hanna and Cambridge University scientists have made a first-in-the-world breakthrough: creating human primordial cells. The group has turned back the clock on human cells to create primordial germ cells: the embryonic cells that give rise to sperm and ova. Scientists worldwide have been pursuing this goal for several years.

    Science Tips, August 2014

    Three updates from the labs of the Weizmann Institute: a new technique identifies the exact DNA sequences involved in regulating the fate of blood stem cells; theorizing that tiny black holes ate their way to becoming massive quasars; nanocubes can self-assemble into beautiful, complex structures.

    Stem Cell Reprogramming Made Easier

    Reprogramming adult stem cells so that they are like embryonic stem cells, and thus have the ability to become any type of cell we like, has the potential to change medicine; however, the reprogramming process is inefficient and impractical. Now, Dr. Yaquob Hanna has found that removing one protein changes everything.

    Science Tips, July 2012

    Three updates from the Weizmann Institute: fool's gold regulates environmental oxygen; finding a molecular mechanism behind faulty stem cells and cancer; and solving the mystery of where importins – proteins critical to healing nerve damage – are produced.

  • Why Chemotherapy Fails

    Prof. Ehud Shapiro leads research that shows how leukemia can evade chemotherapy. Using his method of mapping the family trees of cells, the team found that slowly dividing cancer cells are most likely to survive the toxic therapy. This could lead to new ways of fighting cancer.

    New Stem Cells Go Back Further

    One challenge in using induced pluripotent stem cells (iPSCs) – which are ""reprogrammed"" regular cells – is that they retain traces of their former identity (e.g., skin cells). Dr. Jacob Hanna has now created iPSCs that are completely reset to the earliest possible state. This could lead to applications such as custom-grown transplant organs.

    Science Tips, October 2012

    Three updates from the Weizmann Institute: how bacteria that live with arsenate are able to identify it; previously unknown stem-cell ""bodyguards"" in the bone marrow; and a finely tuned immune system ensures response to common ills.

    Unraveling the Mysteries of Science and Disease

    Weizmann Prof. Emeritus Michel Revel's long, brilliant career includes co-developing Copaxone® and Rebif®, two of the world's leading MS drugs. At 75, rather than retire, he's still breaking ground: his new biotech firm is developing applications for human embryonic stem cells, aiming to better treat – and cure – diabetes and other diseases.

    Using Young Cells to Fight Age-Related Macular Degeneration

    Israeli company Cell Cure Neurosciences is conducting clinical trials on a stem-cell-based treatment for age-related macular degeneration (AMD), reports Israel21c. The firm's CEO, Charles Irving, conducted his doctoral research in chemistry at Weizmann. Currently, treatment options for AMD – a major cause of blindness in adults – are limited.
