They noted that the forms, which they called electron dense bodies were so small that they could pass through bacterial filters that normally withheld ordinary bacteria with cell walls. The electron dense bodies could persist inside tissue culture cells in the laboratory. Platelet granules are of two types: alpha granules and dense bodies.
