Maribel Díaz-Ricart, Ph.D.

Maribel Díaz-Ricart Endothelial cells (HUVEC) in culture (left image). Exposure of HUVEC to serum from patients with a chronic inflammatory disease (right image) causes endothelial damage, with retraction and release of cells, exposure of the surface to circulating cells, with the adhesion of platelets to the extracellular matrix and attachment of leukocytes (insert) to the remaining cells
