Culture of HL60 cells in 5 x 10(-7) M 9-cis RA together with a wide range of concentrations of D3 resulted in promotion of neutrophil differentiation at 10(-15)-10(-12) D3 , a failure to differentiate and apoptosis at 10(-11)-10(-10) M D3 , followed by co-operativity between 9-cis RA and 5 x 10(-9) M D3 in inducing monocyte differentiation in the absence of neutrophil differentiation .
