This is what platelets look like. For some of us , it is the closest we are going to get to seeing them. Study their shape. Meditate on their line. Perhaps it will help.
All blood cells originate and mature in the bone marrow.
They begin in 'stem' cells, then differentiate into the red cells, white cells, and platelets. Those with ITP have a lower platelet count. It can range from severe cases that hover close to zero to more mild cases where the counts stay in closer to 100,000. 30,000 is often considered a 'safe' count', one that is high enough to protect against cerebral hemorrhage. In people with ITP the platelets are often enlarged.
