Abstract:
1. A method of dissecting a substrate of cultured cells, comprising: separating the substrate of cultured cells into separated portions with a cutting tool that comprises a rotatable shaft having a shallow thread member that forms a continuous groove extending around the rotatable shaft and across a width of the rotatable shaft, the continuous groove extending upward on both sides into sharp crests that define a continuous cutting surface across the width of the rotatable shaft, the continuous groove comprising a shallow, concavely curved surface that has a generally constant thread height across a width of the rotatable shaft, wherein the sharp crests of the continuous cutting surface are rolled through the substrate to cut the substrate into the portions without collecting a substantial amount of substrate in the shallow, concavely curved surface of the continuous groove; and separating the portions from one another to dissect the substrate.
