This indicates that NGC 3860 has crossed though the core of the Leo Cluster and that ram pressure exerted by the dense intergalactic medium in the cluster stripped most of the hydrogen gas out of the galaxy.[12] Also, the gas disk of NGC 3860 is truncated which strongly indicates that the galaxy is undergoing ram pressure stripping as it infalls into the Leo Cluster.[13] See also
