Scientists conducted many experiments with HeLa cells, including sending them to space where they grew more powerful with each trip. A scientist tried using the cells to treat wounds but they became cancerous. In 1965, scientists fused HeLa cells with mouse and chicken cells, creating hybrids that could reproduce. This led to controversy over mixing human and animal cells. Henrietta Lacks' family was both positively and negatively impacted by the success of her cells, with one son converting to Islam in prison after fatally stabbing a neighborhood bully.
