Advances in autologous tissue regeneration in the form of an omentum-derived hydrogel and induced pluripotent stem cell (iPSC)-derived tissue have led to promising therapies for spinal cord injury and cardiac infarction. Asaf Toker, MD, Matricelf, Ness Ziona, Israel, provides an overview of the future of this novel technology. Whilst currently only being assessed in two indications, this method of autologous tissue engineering can theoretically be applied to any type of damaged tissue. Potential indications include Parkinson’s Disease, age-related macular degeneration (AMD) and other musculoskeletal disorders. This interview was conducted during Meeting on the Mediterranean 2022.

Autologous tissue-engineered solutions for spinal cord injuries

Asaf Toker, MD, Matricelf, Ness Ziona, Israel, discusses autologous neural implants for patients with spinal cord injuries, which consists of the implant itself and a scaffold. Omental tissue extracted from the patient via a biopsy is decellularized, resulting in the formation of thermo-responsive hydrogel that serves as the scaffold for the tissue-engineered product. Differentiation of induced pluripotent stem cells (iPSCs) derived from the patient’s mature cells within the thermo-responsive hydrogel results in the formation of neural cells that can connect damaged spinal tissue. First-in-man clinical trials for the product are planned in 2025 in patients with spinal cord injuries. This interview was conducted during Meeting on the Mediterranean 2022.

Restoring cardiac tissue with omentum-based hydrogel implants

Asaf Toker, MD, Matricelf, Ness Ziona, Israel, describes of the development of an autologous omental hydrogel to treat damaged cardiac tissue after a myocardial infarction. In a similar fashion to neural implants for spinal cord injuries also produced by Matricelf, the novel therapy utilizes autologous omental tissue that is decellularized to make a thermo-responsive hydrogel. Induced pluripotent stem cells (iPSCs) derived from the patient’s peripheral blood subsequently differentiates into cardiac tissue when attached to the hydrogel. The implant can either be surgically attached on the injured tissue or can be injected and then solidify once in the body. This interview was conducted during Meeting on the Mediterranean 2022.
