[Secretion of acetylcholinesterase by megakaryocytes in mice]

Acetylcholinesterase, an early and nearly specific marker of Rodent thrombocytic cells, undergoes a typical secretory cycle leading to the release of the enzyme in the demarcation system and the outer cellular space of bone marrow megakaryocytes. This secretion process suggests that megakaryocytes may adapt the amplification of their own precursors by modulating the concentration in cholinergic compounds in hematopoietic tissues.
