Genes that express in precisely timed patterns, known as oscillatory genes, play an essential role in development functions like cell division, circadian rhythms and limb formation. But without a time-lapse view of genetic expression, these genes have gone largely undiscovered.

An algorithm developed by Co-Director James Thomson and colleagues is giving scientists a new way to identify the dynamics of oscillatory genes, and perhaps defining the roles of these early-development forces for the first time.

A paper published in this week’s online edition of Nature Methods describes this new statistical approach, called “Oscope,” which helps identify oscillating genes in single-cell RNA-sequencing experiments. The key to Oscope is examining cells from an unsynchronized population, where the cells are in different developmental states.

A clinical trial using stem cells to treat people who have lost their vision due to retinitis pigmentosa (RP) has treated its first four patients at UC Irvine. CIRM, California’s stem cell agency, is funding the FDA-approved trial, which is led by Dr. Henry Klassen of the Gavin Herbert Eye Institute in Irvine. Research by Steve Fisher, Geoff Lewis and colleagues in the UC Santa Barbara Center for Stem Cell Biology and Engineering in the Neuroscience Research Institute contributed to the pre-clinical work that led to this first ever stem cell trial for RP. The four patients are legally blind because of retinitis pigmentosa, a degenerative disease that slowly destroys cells in the retina, the light sensitive area in the back of the eye that is essential for vision. 

The patients were each given a single injection of retinal progenitor cells. It’s hoped these cells will help protect the photoreceptors in the retina that have not yet been damaged by RP, and even revive those that have been damaged but not yet destroyed by the disease.Worldwide almost 1.5 million people suffer from RP. It is the leading cause of inherited blindness in the developed world. There is no cure and no effective treatment.

Congratulations to Brett Cook (BMSE grad) and Alex Sercel (MCDB undergrad), both in the Feinstein Lab, whose team won Second Prize ($3,500) in the UCSB Technology Management New Venture Competition. They were also awarded the Elings Prize ($5,000). Their startup company, Chemoguard, is developing personalized toxicity screening of chemotherapy treatments using induced pluripotent stem cell technology.

Pioneering research using stem cells to regenerate eye tissue conducted by MCDB’s Dennis Clegg and co-workers may one day help people with age-related macular degeneration (AMD). As the first person to hold the newly endowed Wilcox Family Chair in BioMedicine, Clegg is poised to bring stem-cell-based therapy for AMD to Phase I clinical trials.
