Understanding the question
A positive cell experiment can support a biological hypothesis, but it cannot establish that an intervention improves muscle strength, physical function or health in people. Cells in a dish encounter a controlled environment that does not reproduce digestion, circulation, immune responses, movement or the interactions among organs. Animal experiments add some of this complexity, while introducing differences between species. Human research is needed to investigate whether an intervention reaches the intended tissue, affects its proposed target, provides a meaningful benefit and has an acceptable safety profile in the population being studied.
What a useful investigation needs to consider
Identify the model before interpreting the result. A finding in an immortalized cell line, a primary human muscle cell culture and a person participating in a randomized trial answers three different questions. The word human in a cell description does not make an experiment a human clinical study.
Follow the proposed chain from exposure to target engagement, tissue response and functional outcome. Evidence supporting one link leaves the others unresolved. Consider whether the tested concentration is achievable, whether the endpoint matters to people and whether independent human evidence exists.
