MUSCAT : The award was presented during the 12th annual Researchers Forum held under the theme “Researches are published… Visions are realized.”

The award-winning research was led by Dr. Sulaiman bin Ali Al-Hashimi, Head of the Stem Cell and Regenerative Medicine Laboratory at the Centre for Natural and Medical Sciences Research, University of Nizwa. The study has drawn wide recognition for its innovative contribution to treating chronic wounds, particularly those linked to diabetes.

Dr. Al-Hashimi said the idea for the project emerged from years of research in stem cells and tissue engineering, combined with close observation of clinical challenges faced by patients with chronic wounds. He noted that the rising prevalence of diabetes in Oman has intensified the need for more effective and sustainable treatment solutions.

He explained that traditional wound treatments often focus only on covering injuries, without actively supporting tissue regeneration. By integrating 3D bioprinting into regenerative medicine, the research aimed to bridge this gap through the development of an active bio-dressing that stimulates the natural healing process.

The newly developed three-dimensional dressing is made from carboxymethyl chitosan and infused with the drug tacrolimus. According to Dr. Al-Hashimi, this represents a qualitative shift in wound care, as the dressing not only protects the wound but also regulates inflammation, stimulates tissue regeneration, and allows controlled drug release, significantly improving treatment efficiency.

Laboratory and animal model studies showed promising results in accelerating wound healing and reducing inflammation. However, Dr. Al-Hashimi stressed that the treatment remains in the experimental phase and has not yet progressed to human use, as further safety studies and clinical trials are required.

He also highlighted key challenges faced during the project, including the technical difficulty of developing a biocompatible, 3D-printable biomaterial and the limited advanced infrastructure needed to move research from the laboratory to clinical application. Despite these hurdles, he said the experience strengthened innovation, teamwork, and research quality.

Dr. Al-Hashimi underlined the importance of specialised research laboratories in building a competitive national research ecosystem, noting that achievements in stem cell and regenerative medicine are the result of collective, multidisciplinary efforts. He added that the laboratory places strong emphasis on training young Omani researchers, viewing this as a long-term investment to ensure sustainability and global research collaboration.

Looking ahead, he said the next phase of his work will focus on advancing regenerative medicine and stem cell therapies, refining treatment models, and building national research teams capable of delivering tangible scientific impact.

Concluding his remarks, Dr. Al-Hashimi said the award is both an honour and a responsibility, emphasising that the ultimate goal of scientific research is to serve humanity and improve quality of life.
