Abstract: Described are single-use dispensing devices with a dry chamber containing lyophilized material, a wet chamber containing reconstituting solution, a breaking chamber positioned between and attached to the dry chamber and a first end of the wet chamber. The breaking chamber includes a leak-proof frangible seal that prevent mixing of the lyophilized material and the reconstituting solution until the frangible seal is broken.

Abstract: In certain embodiments, this disclosure describes compositions comprising platelet lysates depleted of fibrinogen. In a further embodiment, the composition further comprises a cell culture medium component. This disclosure also provides a method for preparing the composition, comprising the steps of (a) lysing platelets providing a lysate; (b) removing cell debris; and (c) depleting fibrinogen by forming a removable mass by adding a metal salt such as calcium chloride. Furthermore, the disclosure also describes the product produced using said method.
