Stanford School of Medicine researchers report that the human brain forms from two separate types of stem cells rather than one uniform source. One lineage, marked by the Otx2 gene, produces the midbrain and forebrain responsible for higher-order thinking and speech, while a distinct stem cell type gives rise to the hindbrain, which governs basic functions like heartbeat and breathing. Researcher Kyle Loh says this finding allows scientists to grow hindbrain neurons in a lab dish for the first time.

A Nature Index 2026 feature on regenerative medicine reviews progress in cell therapy and tissue engineering, including the use of induced pluripotent stem cells (iPSCs) to pursue treatments for autoimmune diseases, Parkinson's disease and heart failure. It also notes clinical trials using stem-cell transplants to replace insulin-producing cells in people with type 1 diabetes have shown some success.

Researchers led by immunologist Hongkui Deng at Peking University transplanted lab-grown pancreatic islet cells, derived from a patient's own reprogrammed fat cells, into a young woman with type 1 diabetes. Nearly three years after the 2024 procedure, she no longer requires insulin injections and reports stable blood-sugar levels.

Researchers at Stanford, led by Kyle Loh, report evidence that the brain develops from two separate populations of precursor cells rather than a single universal one. One lineage forms the hindbrain, which governs vital functions like heartbeat and breathing, while a second gives rise to both the forebrain and midbrain. The findings, published in Nature Neuroscience, also describe a method for converting stem cells efficiently into hindbrain motor neurons.

A Stanford research team removed a large section of a mouse's brain and replaced it with tissue grown from human stem cells known as brain organoids. The goal was to give these lab-grown clusters of neurons a living, connected environment closer to an actual brain than a petri dish can offer.

Scientists at the Institute for Stem Cells and Regenerative Medicine in Beijing grew muscle stem cells from mouse quadriceps into small tissue grafts, called myografts, and implanted them under the skin of the animals' backs. The grafts formed organized, blood-vessel-fed muscle tissue that contracted continuously for months, producing gains in muscle mass, strength and bone density and slowing age-related muscle decline, according to a study published in Nature Aging.
