Founded by MIT scientists, the clinical-stage biotech company Frequency Therapeutics discovered a way to reverse hearing loss without hearing aids or implants. Focusing on progenitor cells (which reside in the inner ear and turn into hair cells when humans are in utero, before going dormant) the company injects small molecules into the cochlea, which transform these cells into hair cells that help us hear. During their 200-person trial, the company saw meaningful improvement in patients’ hearing, with some reporting improved speech perception after a single injection that lasted nearly two years.
