Bone marrow stromal cells have been shown to support the growth and differentiation of neuroblastoma cells. In an attempt to study the effects of bone marrow stromal cells on neuronal differentiation, we have co-cultured neuroblastoma × glioma hybrid NG108-15 cells with human bone marrow stromal cells. After co-culturing, clones exhibiting morphological differentiated phenotype and high level of neurofilament expression were isolated. Interestingly, these clones maintain their ability to proliferate in contrast to differentiated NG108-15 cells induced by dibutyryladenosine 3′,5′-cyclic monophosphate. These results suggested that bone marrow stromal cells can induce partial differentiation of NG108-15 cells. 1Department of Biology and Biotechnology Research Institute, The Hong Kong University of Science and Technology 2Department of Surgery, The Chinese University of Hong Kong, Prince of Wales Hospital, Shatin N.T., Hong Kong, China 3Corresponding Author: Mun-Fai Leung ACKNOWLEDGEMENTS: These studies were supported by the ITDC Industrial Support Fund AF/142/96.
