Cell Therapy Tools for Cartilage Repair From Osteoarthritic Knee Joint of Elderly
18.6.2020 08:34:00 EEST | Business Wire | Press release
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.

From Network Automation to Agentic NetOps: NetBrain Sets the Standard for Deploying AI in Network Operations29.5.2026 16:00:00 EEST | Press release
NetBrain Technologies, Inc. today announced major new platform features that advance Agentic NetOps from an emerging category to operational reality. NetBrain's clients are already deploying agents that are diagnosing and remediating issues across complex multi-vendor enterprise networks. These new features further extend the platform with new agent tooling, cross-domain context, and open interfaces for the broader agentic enterprise. Early customer outcomes show the magnitude of the shift: A leading health insurer used NetBrain's Deep Diagnosis agent to diagnose and resolve a weeks old VPN connectivity issue in under five minutes. A large manufacturer resolved a critical device issue with a single prompt, isolating the root cause across the network path in under 20 minutes, saving hundreds of hours of engineer time, shrinking MTTR by more than 95%. A global telecommunications firm found NetBrain's context-grounded agents outperformed a stand-alone frontier LLM on a persistent firewall
Adtran resolves long-running patent litigation, reinforcing commitment to defend innovation29.5.2026 15:00:00 EEST | Press release
Adtran today announced it has resolved a patent litigation matter, resulting in a full settlement and dismissal of all claims with prejudice. The case, initiated in 2020 by a non-practicing entity asserting five patents, was transferred to the US District Court for the Northern District of Alabama in 2021 following a successful motion by Adtran. Adtran subsequently filed counterclaims, including bad-faith patent assertion under Alabama statutory law. The settlement includes payment to Adtran to resolve its counterclaims. Terms of the agreement remain confidential. “This outcome reflects a disciplined and consistent approach to protecting our innovation and our customers,” said Justin Ferguson, SVP and general counsel at Adtran. “We take all claims seriously, but we will not hesitate to defend ourselves when assertions lack merit. Situations like this place unnecessary strain on technology providers and divert resources from advancing networks and services. By advancing our counterclaim
