Body cells receive input from both growth stimulating factors and growth inhibiting factors. In cells with a normal controlled growth there is a balance between both of these. After binding to a receptor, the signal is transferred via a cascade of phosphorylations (signal transduction). When the signal arrives at the nucleus, transcription
Which of the following molecules does NOT stimulate cell division?
Extra info: The epidermal growth factor stimulates cell division in the epidermis, erythropoetin promotes cell division in the bone marrow, and growth hormone supports cell division in many cell types. Tyrosine kinase is an enzyme involved in the signal transduction of growth factors and requires stimulation by growth factors.
