The Japanese government, industry and academia are deliberating health care policies and initiatives to boost Japan’s role in the future of regenerative medicine, experts at Bio Japan 2024 said, as the fruits of cell and gene therapy research come to fruition with new approvals.

The big advantage of cell culture to model diseases is its throughput. “You can play the disease over and over again in the dish,” Clive Svendsen told the audience at the International Society of Stem Cell Research (ISSCR) Annual Meeting held in Hamburg last week. That high throughput, however, is not particularly useful if the cell lines themselves do not accurately model the disease. Cancer cell lines are used in many cell culture experiments far beyond cancer for their ability to grow. But they are “highly abnormal,” Bill Skarnes told the audience at an innovation showcase, as well as quite unstable. “I don’t think the [HEK-293] cell line is the same in your lab as it is in the lab next door,” Skarnes said.

Japanese researchers have transplanted human induced pluripotent stem cells (iPSCs) in a primate model of myocardial infarction and were able to restore heart muscle and function in monkeys. Developed by Tokyo-based Heartseed Inc., the grafted iPSCs consist of clusters of purified heart muscle cells (cardiomyocyte spheroids) that are injected into the myocardial layer of the heart. Published in Circulation on April 26, 2024, the study showed that the cardiomyocyte spheroids survived long term and showed improved contractile function with low occurrence of post-transplant arrhythmias.

On the heels of a $4.6 million series A round in December 2023, cell therapy company Rxcell Inc. is planning to raise another $15 million in 2024 to take its iPSC-derived photoreceptors to the clinic for retinitis pigmentosa and other degenerative diseases of the retina.

San Diego-based Kenai Therapeutics Inc. raised $82 million in a series A round to move its disease-modifying cell therapy for Parkinson’s disease into the clinic. The company, which leverages induced pluripotent stem cell (iPSC) technology, will advance its next-generation allogeneic neuron replacement cell therapies for neurological diseases, specifically completing a clinical proof-of-concept trial for its lead candidate, RNDP-001. The series A was co-led by Alaska Permanent Fund Corp., Cure Ventures and The Column Group, with participation from Euclidean Capital and Saisei Ventures. Proceeds will enable Kenai to submit an IND for RNDP-001 and bring it through the completion of phase I trials, which are expected to begin sometime in 2024.
