RESUMO

Mouse bone marrow and spleen cells were fractionated with the aid of soybean agglutinin and peanut agglutinin. A test for spleen colony-forming units in the isolated fractions showed that the hemopoietic stem cells are agglutinated by both of these lectins. The capacity of the agglutinated fractions to reconstitute lethally irradiated allogeneic mice was investigated. A sequential fractionation of splenocytes from SWR donors by soybean agglutinin and peanut agglutinin, or a single fractionation by soybean agglutinin of splenocytes from BALB/c donors, afforded a cell fraction that successfully reconstituted lethally irradiated (BALB/c X C57BL/6)F1 mice, without complications due to graft-versus-host reaction.
