Abstract

This video describes the technique for long term 2D co-culture of leukemia cells with bone marrow stromal cells to study their interaction with the bone marrow microenvironment. The 2D coculture model utilizes the acute lymphoblastic leukemia cells and the bone marrow stromal or osteoblasts that influence tumor cell phenotype. This study will support investigation of the mechanisms that underlie bone marrow supported survival of leukemic cells during chemotherapy exposure.
Protocol
1. Advanced Preparation Culturing bone marrow stromal cells (BMSC) and osteoblasts (OB). Maintain both BMSC or OB at 37 °C in 6% CO2 and grown on 10 cm tissue culture plates until 90% confluency is reached. Trypsinize BMSC or OB cells and split 1:2 onto new 10 cm plates. The cells are grown to these standards until needed for leukemic co-culturing. 2. Establishing and Maintaining Co-culture Add 5-20 x 10<s…
