A New CRISPR Advance – CRISPR interference system in induced pluripotent stem cells (iPSCs) provides a powerful platform to perform genome-scale screens in a wide range of iPSC-derived cell types, dissect developmental pathways, and model disease.

Reprogrammed Stomach Tissue as a Renewable Source of Functional β Cells for Blood Glucose Regulation – Scientists show that reprogramming of antral stomach cells assembled into bioengineered mini-organs in vitro yielded transplantable units that also suppressed hyperglycemia in diabetic mice, highlighting the potential for development of engineered stomach tissues as a renewable source of functional β cells for glycemic control.
