during a clinical study, a resercher investigates methods of accelerating marrow engraftment following bone marrow transplantation cancer patients. a synthetic glycoprotein , similar in function to granulocyte colony-stimulating factor (G-CSF) , is designed. which of the following is a acharacteristic of G-CSF activity that must be taken into account to assure similar biologic function?
1- activation of a specific cell-surface receptor
2- display of cross-species functionality
3- downregulation of cell growth
4- production by endothelial cells
5- stimulation of megakaryocytic cell production
