CNIO scientists discover a new blood platelet formation mechanism

Thrombocytopenia is a by a lower platelet level than normal. Platelets are tiny cells that participate in the coagulation of blood. Patients usually suffer uncontrolled bleeding that gives rise to hematomas and haemorrhages, and even death. Understanding how these cells are produced by the body, then, could be of great use for alleviating the illness, whose incidence increases exponentially in those patients who undergo chemotherapy. Such is the gravity of the symptoms in these patients that they can even lead to the suspension of the treatment.

Cdk1-Deficient Megakaryocytes
Two Cdk1-deficient megakaryocytes extend proplatelet elongations to produce platelets.


The study has been funded by the , the Ramón Areces Foundation, the Ministry of Economy and Competitiveness, the Community of Madrid and the European Union.
