Which of the following is not a mechanism by which cells communicate with each other?

#Unit 5. Developmental Biology

transcription factors are secreted from one cell and taken up by the target cell, where they influence gene expression
cell surface molecules on adjacent cells interact and initiate a signal transduction process that influences cellular behavior and gene expression
cells form gap junctions with adjacent cells, allowing the passage of small molecules
cells secrete proteins and small hydrophilic molecules, which interact with cell surface receptors on target cells and initiate a signal transduction process that influences cellular behavior and gene expression
