this esm is similar in function to a subspecies of human colony stimulating factor ( csf ) , csf-alpha , since ( i ) it stimulated the production from bone marrow cells of day 14 colonies ( 31 +/- 15 , arithmetic mean +/- 1 s.e.m . colonies , n = 5 ) in semi-solid agar , ( ii ) a large proportion ( 47 +/- 12 % , n = 5 ) of these colonies were eosinophilic and ( iii ) it activated purified peripheral eosinophils as judged by increased autofluorescence ( a mean increase of 23.6 +/- 6.6 units measured by flow cytometry , n = 10 ) .
