fructose 2,6-bisphosphate concentration and 6-phosphofructo-2-kinase activity markedly decrease during differentiation of rabbit erythroid cells , being higher in erythroblasts ( 654 +/- 97 pmol/10 ( 9 ) cells ; 238 +/- 81 u mu/10 ( 9 ) cells ) than in reticulocytes ( 40 +/- 15 pmol/10 ( 9 ) cells ; 11 +/- 3 u mu/10 ( 9 ) cells ) and much higher than in mature erythrocytes ( 10 +/- 0.8 pmol/10 ( 9 ) cells ; 2 +/- 1 u mu/10 ( 9 ) cells ) .
