Researchers at Showa and Kansai Medical Universities grew mesothelial-like cells from human iPS cells to repair the peritoneum, the membrane that wears out and ends peritoneal dialysis. A look at the mouse proof-of-concept and why Japan's PD rate is so unusually low.
Japan's iPS cell therapy already treated fresh spinal injuries. Now a Keio University team is preparing a trial for the far harder chronic phase, where more than 100,000 patients have long been told regeneration simply isn't possible.
A Japanese biotech threaded a catheter into a failing heart and delivered iPS-derived muscle without opening the chest. Inside the world's first trial of its kind.
On May 20, 2026, Japan added three ultra-expensive regenerative medicines to public insurance coverage: Amshepri (world's first iPS cell-derived drug, for Parkinson's), Akugo (stem cells for traumatic brain injury), and Zolgensma Intrathecal (gene therapy for SMA patients aged 2+). Prices range from 55 million yen ($352K) to 167 million yen ($1.06M). We explain why these drugs cost so much, how Japan's high-cost medical expense system shields patients, and whether prices might fall over time.
A Japanese team led by Prof. Takanori Takebe (Osaka & Science Tokyo) and Dr. Mureo Kasahara (National Center for Child Health and Development) plans the world's first pediatric clinical trial of UTOpiA, a bioartificial liver that perfuses blood through iPS-derived liver organoids. Animal trials showed 90% survival. How it compares with King's College London's HELP trial and Beijing's CiPS-BAL.
Kyoto University's iPS Cell Research Institute (CiRA) has succeeded in producing 'helper T cells'—the conductors of the immune system—from iPS cells without using mouse feeder cells. The breakthrough opens a path beyond the limits of $500K+ CAR-T therapy, especially for patients whose own immune cells are exhausted from chemotherapy. Here's how Japan's progress compares with US efforts at Memorial Sloan Kettering and China's surging T-cell pipeline.
Panasonic has partnered with Kyoto University's iPS Cell Research Foundation to begin proof-of-concept trials for fully automating iPS cell establishment at Osaka's Nakanoshima Cross. The goal: slash per-patient costs from tens of millions of yen to around 1 million yen. How does Japan's approach compare with US rival Cellino's laser-driven biomanufacturing?
Japan's iCELL BANK launched in April 2026, offering individuals the ability to create and cryopreserve their own iPS cells for future regenerative medicine. Using ID Pharma's Sendai virus vector technology, the service marks a new phase in commercializing the Nobel Prize-winning iPS cell technology for everyday consumers.
Nobel laureate Shinya Yamanaka explained iPS Cell 2.0 on NTV's Bankisha. From next-gen stem cell tech overcoming current limitations to universal blood platelets that bypass blood-type matching, plus Japan's historic first-ever iPSC drug approvals in 2026 — a comprehensive look at where iPS cells stand 20 years after their discovery.
Not the iPS cells themselves, but the liquid they're grown in, injected into arthritic knees. A Japanese team's world-first study showed 71.4% improvement by international criteria with no serious adverse events. We look at what a seven-patient uncontrolled pilot can and cannot tell us, and where conditioned medium sits in Japan's regulations.
Japanese startup Orizuru Therapeutics has begun clinical trials transplanting iPS cell-derived islet cells into diabetes patients. The first-ever transplant surgery succeeded in February 2025, with company-sponsored trials planned in Japan and the US. Over a decade after Professor Yamanaka's Nobel Prize, Japan's regenerative medicine enters the practical stage.
On March 6, 2026, Japan's Health Minister formally approved ReHeart (severe heart failure) and Amshepri (Parkinson's disease), the world's first iPS cell-derived medical products. In May, Amshepri became the first iPS product covered by public insurance, priced at 55.3 million yen. Here are the conditions, the seven-year deadline, and the objections.
Researchers at Kyoto and Hiroshima Universities created iPS cells from bonobos, chimpanzees, and gibbons, then achieved the world's first differentiation into limb bud mesoderm cells. Inside Japan's Whole-Zoo iPS Cell Project and its work on primate evolution, conservation, and zoo veterinary medicine.
Osaka University spinoff Reimei has launched the world's first corporate clinical trial of a corneal epithelial cell sheet made from donor-derived iPS cells. Learn how this breakthrough could solve the global corneal donor shortage, restore vision for millions, and where Japan's regenerative medicine regulation stands versus the US FDA.
Japan's health ministry panel has approved two iPS cell-derived regenerative medicine products — a world first. "ReHeart" for severe heart failure and "Amshepri" for Parkinson's disease are set to become the first commercially available iPS cell therapies. Twenty years after Shinya Yamanaka created iPS cells from mouse cells, Japan's groundbreaking technology is finally reaching patients.
Marking 20 years since Professor Shinya Yamanaka's groundbreaking iPS cell discovery, Japan advances toward world-first regulatory approval of regenerative medicine products in 2026. Explore the latest clinical trials for Parkinson's disease treatment and heart failure therapy, and discover how this Japanese innovation is revolutionizing global medicine.
