Differential expression of candidate HSC regulators by UG26.1B6 and UG26.3B5 stromal cells. Real-time PCR was performed for β-NGF, MIP-1γ, and Bmp4 on three RNA samples from UG26.1B6 (HSC-supportive) and UG26.3B5 (less supportive) stromal clones. Graphs show the relative expression levels of each factor in both cell lines. n = 3. For MIP-1γ and Bmp4, P < 0.001.
