Canalicular system platelets
WebThe open canalicular system (OCS) is an internal membrane structure found in platelets. First identified 50 years ago, the OCS comprises a tunneling network of surface-connected channels that appear to play an important role in platelet function. WebThe existence of two separate groups of membrane-enclosed channels in platelets, the open canalicular system (OCS) and the dense tubular system (DTS), has been recognized for several years. The present study has employed ultrastructural observations on normal platelets, cells from a child with the g …
