title: Abnormal in vitro granulopoiesis in phenotypically normal parents of some children with congenital neutropenia.
abstract: Bone marrow from hematologically normal parents of congenitally neutropenic children showed defective myeloid differentiation in vitro. In one family only the mother's marrow differentiated abnormally; in the second family both parents demonstrated abnormal myeloid differentiation. In vitro culture of bone marrow may be useful in establishing the mode of inheritance of some forms of familial neutropenia.
