A closer look at Quinton Smith’s groundbreaking stem cell engineering: These are vessels-on-a-chip they’ve enabled to self-assemble on the chip by modulating specific cell ratios and hydrogel concentrations. The red cells are blood vessel cells and the green are microspheres that show the vessels’ functionality. They use these microvascular networks to test drugs for liver diseases and preeclampsia, which disproportionately affect Black and Latino populations. | The Henry Samueli School of Engin

The evolution of stem cell research in the past 20 years has been exciting and in some ways surprising. Scientists are focusing their attention and research dollars on the most promising treatments and that's created a shift in emphasis toward adult and iPS cell research. Stem Cell Research Facts produced a short documentary that explores the history and the direction of stem cell treatments.
