CD34 expression on HSC in fetal and neonatal liver and spleen.
Expression of c-Kit and CD34 on Lin− BM cells of neonatal liver, neonatal spleen, and fetal liver cells (16 dpc) of Ly-5.2 mice, and the percentages of Ly-5.2+ cells in B220+cells (B), Thy-1+ cells (T), and Gr-1/Mac-1+cells (M) in Ly-5.1 recipient PB 8 to 10 weeks after transplantation. The recipients were transplanted with CD34− (R1), CD34low (R2), and CD34high (R3) cells (1 × 102 [●], 1 × 103 [○], 2 × 103 [▪], 1 × 104 [■] and 2 × 104 cells [⧫]) in Ly-5.2 neonatal liver, neonatal spleen, and fetal liver cells (14-18 dpc). The averages of the proportions of the 3 fractions in Lin−c-Kit+cells of neonatal spleen, neonatal liver, and fetal liver cells (n = 2, 2, and 4) are shown in each window in the flow cytometry graphs.
