Effects of BMP-2 on cellular proliferation of various human myeloma cell lines.

Myeloma cells were cultured with 50 ng/mL of BMP-2 for 48 hours, and cell viability was measured by MTT assay as compared with control cells cultured without BMP-2. Results are expressed as the mean ± SD of at least 3 different experiments. *HS-Sultan cells were cultured for 72 hours.
