SCP2 and neuroblastoma: To assess the transcription activity of the core promoters, we transiently transfected two types of human cell lines, HeLa S3 (human cervical carcinoma cells) and SH-SY5Y (human neuroblastoma cells originating from bone marrow tissue), with the pRc/CMV, natural CMV, SCP2 or SCP3-driven EGFP expression vectors, and imaged the fluorescence signals expressed by the transfected cell populations.
