Red Blood Cells (RBC) do not "form a scab", they are merely trapped in the scab during blood coagulation. Platelets, carried in the blood serum form the scab by sticking to the endothelium (inside) of the blood vessel forming a plug to end bleeding. Clotting proteins than begin to condense and form the hard scab. Human RBC do not have DNA and therefore cannot act in response to external stimuli like a cut.
