You won't have much luck searching keywords on your topic with terms like "alternative" or "replacement". Instead, use terms referring to a specific alternative (for example, "organ on a chip"; "in vitro"; "explant"), or terms such as "research design", "sample size", or "minimally invasive". Use the quotations around the terms to find exact phrases.
