A new study by researchers at University of California, San Diego School of Medicine reveals a protein’s critical – and previously unknown -- role in the development and progression of acute myeloid leukemia (AML), a fast-growing and extremely difficult-to-treat blood cancer. The study was published July 23 in Cell Stem Cell.

Stem Cell Transplantation for Children with Rare Form of Leukemia Improves Outcomes

Researchers in the Division of Hematology, Oncology and Blood & Marrow Transplantation at CHLA have shown greatly improved outcomes in using stem cell transplantation to treat patients with a serious but very rare form of chronic blood cancer called juvenile myelomonocytic leukemia (JMML).

Using Low-Dose Irradiation, Researchers Can Now Edit Human Genes

For the first time, researchers have employed a gene-editing technique involving low-dose irradiation to repair patient cells, according to a study published in the journal Stem Cells Translational Medicine. This method, developed by researchers in the Cedars-Sinai Board of Governors Regenerative Medicine Institute, is 10 times more effective than techniques currently in use.

A Human Heart-on-a-Chip Screens Drugs for Potential Benefit, Harm

A research team funded by the National Institutes of Health has generated a novel system for growing cardiac tissue from undifferentiated stem cells on a culture plate. This heart on a chip is a miniature physiologic system that could be used to model early heart development and screen drugs prescribed during pregnancy. Researchers from the University of California (UC) Berkeley; the Gladstone Institutes, in San Francisco; and UC San Francisco, reported their work in the July 14, 2015, online issue of Nature Communications.

Fruitfly Sperm Cells Reveal Intricate Coordination in Stem Cell Replication

Stem cells are key for the continual renewal of tissues in our bodies. As such, manipulating stem cells also holds much promise for biomedicine if their regenerative capacity can be harnessed. Researchers are making headway in this area by studying stem cells in their natural environment in fruitflies.

Stem Cells Might Heal Damaged Lungs

As bone marrow and lung stem cells are quite similar, the Weizmann Institute’s Prof. Yair Reisner investigated 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.
