Abstract
The methyl cellulose modification of the CFUe technique has been applied to 14 day fetal liver and adult bone marrow and spleen from CBA/CA mice. Optimized doses of fetal calf serum, α-thioglycerol, erythropoietin and cell suspensions have been obtained from dose response curves in order to standardize the technique. The slopes of the erythropoietin and cell dose response curves indicate a greater sensitivity by fetal liver to the hormone than bone marrow or spleen. The proportion of cells in the DNA synthesis phase of the cell cycle, as measured by the CFUe technique, has been estimated by administering hydroxyurea. Two hours after the drug was injected, 89% of fetal liver cells, 71% of bone marrow cells and 81% of spleen cells were found to be in the S-phase. Mit einer modifizierten Methyl-Cellulose-Technik wurde der CFUe-Gehalt von fötaler Leber (Gestationsalter 14 Tage), von erwachsenem Knochenmark und Milz bei CBA/CA-Mäusen bestimmt. Die optimalen Kulturbedingungen wurden untersucht, indem Dosis-Wirkungskurven für fötales Kalbserum, α-Thioglycerol, Erythropoetin und Zelldosen durchgeführt werden. Fötale Leberzellen zeigten ein besseres Ansprechen auf Erythropoetin als die Knochenmark- und Milzzellen der Maus. Weiterhin wurde die Proliferationsaktivität der CFUe von verschiedenen hämopoetischen Geweben mit Hilfe des S-Phase-spezifischen Zytostatikums Hydroxyharnstoff untersucht. Der Anteil der CFUe in DNA-Synthese war verschieden für fötale Leber (89%), erwachsenes Knochenmark (71%) und Milz (81%).This publication has 30 references indexed in Scilit:
