In vitro sensitivity of Ba/F3 cells to tyrosine kinase inhibitors. Response of 14 Ba/F3 cell lines expressing Ph-like ALL alterations to targeted agents. Cell viability was measured after 48 hours using CellTitre-Blue viability assay. IC₅₀ values were calculated using serial dilutions and linear regression. The heat map shows IC₅₀ values (log₁₀ scale) according to the color key. Cell lines (columns) and drugs (rows) were ordered by unsupervised clustering.
