S ummary . A harvesting technique which gives information about the spatial relationships between cells grown in diffusion chambers in mice has been designed. The principle is that cells are centrifuged directly from the chamber clot onto a slide during pronase treatment. The technique has been applied to normal human bone marrow cells grown in diffusion chambers. The slides show that the cells are situated in clusters. A limiting dilution assay of progenitor cells based on the presence of granulopoietic clusters in the chambers demonstrates the use of the method for quantitation of progenitor cells.
