Established Elixirgen Scientific, Inc. Japan Branch in Yokohama City, Kanagawa Prefecture.
Relocated Japan Branch to the Life Innovation Center in Kawasaki City.
Expanded into Shonan Health Innovation Park in Fujisawa City, Kanagawa Prefecture, and started mRNA manufacturing contract business (CDMO).
The Japan Branch was incorporated as Elixirgen Scientific Japan Co., Ltd.
Reiko Co., Ltd. acquired additional shares of the consolidated subsidiary, becoming a wholly owned subsidiary.
Ricoh Biosciences Co., Ltd. will exhibit at BioJapan 2026, to be held from October 7 to 9, 2026. Its booth is at the Yokohama-Kawasaki Pavilion (B-05), where it will introduce a manufacturing platform for mRNA drug development and a disease model panel for neurodegenerative diseases. Advance registration on the official website is required to attend.
Research using contract-manufactured modified mRNA was published in Science Advances on September 2, 2026. A research group at Osaka University reported that intra-articular administration of Col IX (Col9a1 and Col9a2) mRNA maintained and improved cartilage structure and mechanical properties in a rat osteoarthritis model, suppressing disease progression. Our company manufactured the modified mRNA using chemical modifications including a CleanCap-3Me structure and N1-methylpseudouridine (m1Ψ). The findings suggest a potential new treatment strategy to prevent cartilage matrix breakdown at the very early stages of osteoarthritis.
From August 17 through September 30, 2026, Quick-Tissue™ frozen differentiated cells and differentiation induction kits are available at special prices. The minimum order for reagent kits has been reduced from five kits to two, and frozen differentiated cells can be purchased in sets of ten. Eligible products ship free during the campaign, and an amount equal to the purchase price will be discounted from the next commissioned service.
Ricoh Biosciences is offering special prices on Quick-Tissue™ frozen differentiated cells and differentiation induction kits from August 17 to September 30, 2026. The campaign offers four benefits, including a lower minimum order quantity, free shipping, and bundle-purchase benefits.
