title: Improved method for cytogenetic studies of solid tumors.
abstract: Solid human tumors were dissociated with collagenase, cultured for 16-48 hours, and harvested for cytogenetic preparation. Of the 19 tumors used, 14 showed sufficient numbers of metaphases to be useful for chromosome analysis.
