The primary advantage of organ culture over cell culture is the retention of structural integrity. Unlike cell culture, which lacks in vivo structural complexity, organ culture allows for the recreation of the whole three-dimensional structure of the organ. This ensures that cell-to-cell communication and association are greatly preserved, enabling cells to interchange signals via interaction or adhesion.

Additionally, organ culture helps in studying the actual behaviour of a tissue in an in vitro system. It allows for a better understanding of the biochemical and functional characteristics of an organ, making comparisons with in vivo organs easier. It is also highly suitable for studying the effects of hormones individually or in combinations.
