In case of platelets, progenitor cells differentiate into megakaryocytes, which are responsible for creating platelets.

在血小板的程中，造血胞会分化巨核胞；由巨核胞来造血小板。

When it binds, those cells activate the JAK2 gene which makes them divide and mature into megakaryocytes and platelets.

当结合后，胞激活JAK2基因，促使胞分化、熟，变为巨核胞和血小板。

Platelets. The blood platelets are actually cell fragments rather than complete cells. Platelets are formed in the bone marrow from giant multinucleated cells called megakaryocytes.

血小板。血小板实际上是胞碎片而不是完整的胞。血小板在骨髓中形，来自于被称为巨核胞的巨大的多核的胞。
