A tissue collection apparatus for initiating bone formation ex vivo. A substantially cylindrical body includes a closed end, an internal surface, an open proximal end and a detachable closure cap for preventing a flow of air at the juncture thereof and the substantially cylindrical body. A first portion is integral with the detachable closure cap for allowing a flow of a collection of bone growth elements substantially having a quantity of platelets, mesenchymal cells, bone cells, blood and tissue cells, collagen and noncollagenous proteins comprising components thereof to flow into the substantially cylindrical body and strike a procoagulant surface of an interpositional admixture element so as to induce aggregation and degranulation of the quantity of platelets. The interpositional element is interposed within the substantially cylindrical body. A second portion integral with the substantially cylindrical body is provided to allow the connection of vacuum means. The second portion includes a second internal passage to allow a flow of air there through.
