Cedars-Sinai study shows rapid healing of heart damage with cell therapy

A scientific technique that rapidly increases the body's production of anti-inflammatory cells promoted healing from heart attacks in mice, according to a new study by investigators from the Smidt Heart Institute at Cedars-Sinai. Once adapted to treat humans, the technique could potentially be used to repair heart muscle damage after a heart attack and be applied to a variety of inflammatory disorders.

Study develops fused neural organoids with leptomeninges

A new study in the peer-reviewed journal Stem Cells and Development describes the development of a co-culture system of neural organoids generated from human induced pluripotent stem cells (iPSCs) fused with fetal leptomeninges from mice with fluorescently labeled meninges, called leptomeningeal neural organoid (LMNO) fusions.

Stanford study reveals glucose's surprising role in cell differentiation

The sugar glucose, which is the main source of energy in almost every living cell, has been revealed in a Stanford Medicine study to also be a master regulator of tissue differentiation - the process by which stem cells give rise to specialized cells that make up all the body's tissues.
