[Study on expression of adherent proteins related to regulation of hematopoiesis in long-term cultured human bone marrow stromal cells].

Objective: To study the molecular basis of bone marrow stromal cell supporting hematopoiesis.

Methods: Immunoelectron microscopic localization of adherent protein related to regulation of hematopoiesis was performed by immunocolloidal gold labelling technique in the adherent layer of long-term cultured human bone marrow stromal cells (LTCHBMSC).

Results: Adherent proteins were found to be expressed on LTCHBMSC.
