Gel Treatment to Heal Damaged Heart Cells


Scientists at University of California has conducted a trial on a unique gel which would help to heal damaged heart tissues. The gel is hydrogel and can be injected directly to damaged part.

The gel is in trial and may seek FDA approval soon. It is prepared from tissues known as connective tissues. Connective tissue is one of the four basic types of tissue. The tissues used in gel are derived from Decellularized Ventricular Extracellular Matrix of heart. Derived tissues are then transformed into powder by freezing and drying. The powder along with special liquid, is then used to inject in heart.

Formation of new cells is initiated by connective tissues when the liquid consolidates and becomes partly solid. The overall process triggers formation of new cells at the injected area without disturbing functionalityies of heart. This eventually results in replacement of damaged cells with new cells. Apart from healing, the hydrogel also generates signals to stop further damage of the cells.

Other materials, used to heal damaged cells of heart, experimented on mice are suppose to be delivered by syringe or needle. But, none of them were suitable for delivery through catheter as most of the material blocked catheter because of rapid consolidation.

Scientists found, during experiment on rats, the gel very feasible as it was easily accepted by body at body temperature. Unlike other treatment hydrogel did not show side effects such as abnormal heart beats. That way the hydrogel has been concluded as safer.

Dr Karen Christman is one of the authors involved in trial.

The trial result has been demonstrated in Journal of the American Cardiology.
