The graft is tailored to the biological, physical, and clinical needs of the patient. The basis for the production of the living bone graft is mesenchymal cells derived from the patient's adipose tissue. The product is in clinical trials; the company estimated that marketing approval would be granted in 2024–2025. MesenCure is a drug for the treatment of cytokine storm that creates life-threatening respiratory distress. The drug is manufactured from mesenchymal cells derived from the adipose tissue of healthy donors and is intended for the treatment of inflammation in the respiratory system, whether caused by the novel coronavirus or any other virus, or by bacteria or exposure to other pathogens. The drug is in clinical trials in hospitals in Israel. In July 2021, the company reported significant success of the drug in treating severe COVID-19 patients.
