Revised pH dataset

HUVECs were cultured in control medium (approximately pH 7.4) and exposed daily to low pH medium (approximately pH 7.0) for 20 minutes, then returned to control medium, forming the ‘Change’ group. Comparison groups included cells cultured under control medium (‘Control’ group) or under low pH medium (‘Low pH’ group). Cell proliferation, tube formation, migration, and protein/gene expression were assessed.
