The replacement of animals as test subjects is one step closer to reality with the successful testing of multi-organ "human-on-a-chip" models to recapitulate the 28-day experiments typically used in animals to evaluate the systemic toxicity of drug and cosmetic compounds. As published and featured as a frontispiece in the prestigious peer-reviewed scientific journal Advanced Functional Materials, the microfluidic device with interlinking modules containing human-derived heart, liver, skeletal muscle and nervous system cells was able to maintain cellular viability and record cellular function in real-time for 28 days.
