LRRK2 and Platelet storage pool disease: This cell system consisted in induced pluripotent stem cell (iPSC)‐derived DAn generated upon cell reprogramming of parental skin cells from L2PD patients carrying the G2019S mutation (n = 4), sPD patients without LRRK2 mutations (n = 6), and gender‐ and age‐matched healthy subjects (n = 4) (Sanchez‐Danes et al, 2012a,b).
