A break through feat of growing pluripotency expressing cells from osteoarthritis (OA) affected cartilage tissue of knee joints of elderly has been reported by orthopedicians and cell culture experts led by Dr Shojiro Katoh, President, Edogawa Hospital. OA affects, knee joints of millions globally and those with severe disease, undergo Total Knee Arthroplasty (TKA), in which damaged cartilage is replaced with artificial knee prosthesis. Dr Katoh, during TKA surgery, took portions of the damaged tissue, which otherwise is discarded, isolated chondrocyte cells in tissue engineering lab, and could culture them as fully reorganized healthy cartilage tissue, expressing biomarkers relevant to pluripotency.

Cartilage of the knee joint acts as a cushion between bones of the thigh and leg and absorbs the body weight. When cartilage is damaged due to sports injury, trauma or wear and tear, it causes joint pain and disability. In early stage of the disease, Autologous Chondrocyte Implantation (ACI) or Matrix Assisted Chondrocyte Implantation (MACI) are practiced. Such cell therapies use patient’s own cartilage cells, harvested from healthy, non-weight bearing area, grown in lab, and transplanted to replace the damaged tissue, to restore functionality.

"This could probably be the world’s first report of Osteoarthritis tissue, yielding cells expressing pluripotency markers," said Dr. Katoh, citing their publication in Regenerative Therapy Journal (https://www.sciencedirect.com/science/article/pii/S2352320420300274), also presented in the 19th Japanese society for regenerative medicine meeting. "Our technique may help utilize OA affected cartilage, discarded as biomedical waste, as a source of tools of cell therapies viz., cells, cell secreted growth factors, and exosomes to repair cartilage defects in regenerative medicine," he added.

Edogawa hospital, located in eastern Tokyo, has many senior citizens. "Contrary to the age-old belief that Wisdom is the strength of elders, this research finding has made me humble, to learn about nature’s hidden strength in their physical intricacies too, fueling our enthusiasm," said Dr Katoh adding a philosophical humility to his accomplishment. His Edogawa Evolutionary Lab of Science (EELS), having confirmed hyaline phenotype is now evaluating miRNA-140 and Hyaluronan expression of chondrocytes.

This technology has a potential to solve cartilage damage of approximately 12 million people annually worldwide, according to JBM Inc, and GN Corporation, co-applicants to a patent and research partners to EELS.

Impartner Launches the First CPQ Built for Partners20.8.2026 16:00:00 EEST | Press release

Impartner, the leading partner revenue orchestration platform, today announced the launch ofImpartner CPQ, giving partners a direct path to create and advance quotes within the Impartner PRM platform. The new capability enables faster movement from opportunity to submission while giving vendors control over the rules, products, pricing, and approvals that govern each transaction. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260820479441/en/ Give partners a faster path from opportunity to quote with Impartner's CPQ. For many partnership programs, quoting remains a largely manual process. Partners often depend on vendor sales teams to prepare quotes because traditional CPQ systems are designed primarily for direct sellers or require additional licensing for external users. The result is a slower path from opportunity to revenue, increased administrative work for channel teams, and a partner experience that can limit the impa

Scientist.com Expands R&D Platform Capabilities with SciSure’s Integrated LabOps Inventory and Compliance Services20.8.2026 15:55:00 EEST | Press release

Scientist.com, the life sciences industry’s leading AI-enabled R&D orchestration platform and digital marketplace, today announced an expansion of its platform capabilities through an integration with SciSure’s lab management and EHS compliance tools. The partnership gives biopharma organizations a more unified workflow connecting scientific procurement directly with laboratory operations. “By bringing SciSure’s inventory management, safety, and compliance capabilities into the Scientist.com ecosystem, we are closing the gap between sourcing reagents and safely managing them in the laboratory,” said Jon Zibell, VP of Global Alliances at SciSure. “Together, our platforms connect product information, safety checks, and inventory management, giving research, lab operations, and EHS teams greater visibility from purchase request through disposal.” The integration connects procurement, safety, inventory, and compliance in a single connected workflow.

NETFORCE Accelerates Its U.S. Industrial Expansion as a New Intermediate-Force Market Takes Shape20.8.2026 15:23:00 EEST | Press release

For the first time, major U.S. federal agencies are beginning to structure procurement around a new category of intermediate-force equipment, giving officers an additional option between verbal presence and higher levels of force. NETFORCE believes companies establishing themselves at this early stage will benefit from a significant first-mover advantage as this category expands nationwide. This is precisely the market NETFORCE anticipated years ago, having invested heavily in research, industrialization and international intellectual property well before the category attracted attention.

Esri Expands World Imagery with Airbus High-Resolution Basemap Coverage for 2,000 Cities Worldwide20.8.2026 15:00:00 EEST | Press release

At the 2026 Esri User Conference (UC), the global leader in location intelligence announced a significant enhancement to its World Imagery basemap through a new agreement with Airbus. The collaboration will enable Esri to provide ArcGIS users with high-resolution imagery coverage for approximately 2,000 cities around the world through the addition of the new Airbus, Nearmap, and Vantor imagery. The added data is part of an enhanced imagery initiative for the World Imagery Basemap, the most widely used map service in ArcGIS, and was highlighted during this year’s Esri UC Plenary. Beginning in the second half of 2026, Airbus will deliver 30 cm imagery designed to provide more current and detailed visual context for ArcGIS users worldwide. Airbus imagery is highly accurate, color-consistent, and provides nearly cloud-free coverage with minimized haze and seasonal variation between contiguous images. As part of the broader World Imagery enhancement program announced at the 2026 UC, Esri al
