Purification of erythroblastic nests
AJ Macario, C Dugan, IL Perez-Lloret and E Conway de Macario
We describe a method for preparing purified erythroblastic nests in large
numbers (approximately 10(6)/run) in three steps: (1) induction of splenic
erythropoiesis in mice, (2) preparative differential centrifugation for the
removal of erythrocytes and single cells from spleen cell suspensions, and
(3) sedimentation in an isokinetic gradient of Ficoll 400 in Joklik's
modification of minimum essential medium. Viability of isolated EN is very
high, as demonstrated by the trypan blue exclusion and in vitro erythrocyte
formation methods.
